Definitions
- Atherectomy catheters are used to remove material from a blood vessel to open the lumen of the blood vessel and improve blood flow through the vessel.
- Atherectomy catheters generally have cutters positioned at or near the distal end of the catheter. Some atherectomy catheters are designed to cut along only one portion of their distal circumference. Such 'directional atherectomy' catheters must be manipulated such that the cutter is positioned adjacent to the material to be cut. Such manipulation can involve urging the cutter against one side of a blood vessel so that material can be cut, and can involve rotating the proximal region of the catheter shaft so as cause rotation of the distal region of the catheter and thereby position the distally located directional cutter adjacent to material to be cut.
- the present invention is directed to devices and methods for manipulating and urging a cutting element of an atherectomy catheter such that the cutter is positioned adjacent to the material to be cut.
- the present invention provides a manipulator which is used with an atherectomy catheter to rotate, translate, or both rotate and translate the catheter.
- the atherectomy catheter may have a cutting element that is able to extend through a window to cut material of interest.
- the manipulator can be actuated using one hand only.
- an atherectomy catheter is provided with a pre-formed distal region. The pre-formed distal region urges the atherectomy catheter cutter into forcible contact with the inner wall of a vessel. When the cutting element encounters tissue, forces that tend to deflect the cutting element away from the tissue are resisted by the pre-formed distal region of the catheter.

- a distal portion of the shaft is shaped to provide an apposition force to urge the cutting element against the vessel wall.
- Catheter 50 may be similar to catheter 20 described above but may be any other catheter with a working element, having shaft 56 similar to shaft 26 described above or another shaft, in any case with the addition of jog 5 Ij and preformed bends 5 Ip, 5 Id.
- Catheter 50 is also comprised of working element 52 and window 54 which may be similar in construction, materials, and function as working element 22 and window 24 respectively.
- the window 54 is positioned at a radially inner position on the shaft so that the working element 52 is urged against the vessel wall when the catheter is positioned within a vessel.
- Manipulator 55 may be comprised of manipulator 10, 30 described above or may be another manipulator. Use of manipulator 55 with catheter 50 is optional.
- Handle 58 may be similar to handle 28 described above but may be any other handle.
- Catheter shaft 56 includes jog 5 Ij and preformed bends 5 Ip, 5 Id.
- Jog 5 Ij is comprised of a hinge structure that allows distal portion 56d of shaft 56 to abruptly bend in relation to mid portion 56m of shaft 56.
- Catheter structures capable of jog are further described in US Patent Application 10/896,741 , filed July 21 , 2004 and published as US 2005/0177068 Al, paragraphs [0092] to [0094], [0100] to [0102], [0105] to [0107] and Figures 1, IA, 2, 4A and 4B.
- US Patent Publication US 2005/0177068 are hereby incorporated herein in their entirety.
- preformed bends are formed such that the mid portion and the portion of the catheter shaft proximal of the mid portion lie within a first plane and the hinge element is configured to permit bending of the distal portion with respect to the mid portion only in the first plane.
- Preformed bends 5 Ip, 5 Id may be formed by constraining distal portion 56d in metal molds followed by application of heat to cause catheter 56 to take the shape of the mold, or other means as are known to those of skill in the art.
- Preformed bend 5 Ip has a lesser angle 53p than preformed bend 51d angle 53d.
- Preformed bend 51p angles of 90 to 150 degrees are contemplated. In one embodiment preformed bend 51p angles are 100 to 120 degrees.
- angle 53p are 95, 105, 110, 115, 125, 130 or 140 degrees.
- Preformed 5 bend 5 Id angles 53d of 100 to 180 degrees are contemplated.
- preformed bend 51d angles are 120 to 140 degrees.
- angle 53d is 110, 130, 150, 160, or 170 degrees.
- the length from preformed bend 5 Ip to preformed bend 5 Id is generally greater than the length from preformed bend 5 Id to jog 5 Ij. Lengths from preformed bend 5 Ip to preformed bend 5 Id of 0.5 to 2.0 o inches are contemplated. In one embodiment length from preformed bend 5 Ip to preformed bend 5 Id is 1.00 to 1.25 inches.
- lengths from preformed bend 5 Ip to preformed bend 5 Id are 0.75, 1.5 or 1.75 inches.
- Lengths from preformed bend 5 Id to jog 5 Ij of 0.125 to 1.0 inches are contemplated.
- length from preformed bend 5 Id to jog 5 Ie is 0.375 to 0.625 inches.
- lengths from preformed bend 5 Id to jog 5 Ij are 0.25, 0.5, 0.75 or 0.875 inches.
- the combined bends 51d, 51p and lengths between bends and between bend and jog cause catheter 56 to have a maximum excursion 56e from the unbent portion of catheter 56 to jog 56j.
- catheters of the invention are chosen to have an excursion greater than the diameter of the vessel or conduit that catheter 500 will be used within.
- Excursions 56e of 3 to 40 millimeters are contemplated. In one embodiment excursion 56e is 5 to 8mm. In some embodiments excursions 56e are 4, 5, 6, 7, 8, 10, 12, 15, 20, 25, 30 or 35 millimeters.
- preformed bends 5 Ip and 5 Id are forced to assume angles larger than their undeflected preformed angles while jog 5 Ij allows distalmost portion of catheter 50 to become oriented along inner wall of vessel V.
- This cooperation between jog 56j and bends 5 Ip, 5 Id forces or urges window 54 into contact with inner wall of vessel V as preformed bends attempt to restore their0 undeflected preformed angles.
- Preformed bend 51d maintains apposition force of cutter 52 and window 54 against the inner wall of vessel V at the low end of vessel diameters. As vessel diameter increases preformed bend 5 Ip eventually starts to apply apposition force to the catheter tip as well.
- Urge forces of 0.05 to 0.5 lbs are contemplated.
- the urge force is 0.1 lbs.
- the urge force is 0.075, 0.2, 0.3 or 0.4 lbs.
- Working element 52 such as a cutter, can be extended through window 54 to contact material to be cut, such as atheroma. During cutting, cutting forces tending to deflect cutter away from inside surface of vessel will be resisted by the urge forces produced as described above.
- the distal portion of shaft 56 can be rotated, translated, or both by manipulator 55 (if used) to assure that window 54 is circumferentially oriented so as to contact the material to be cut.
- a catheter 50 having excursion 56e greater than the inside diameter of vessel V is chosen.
- the catheter is introduced over a guidewire into the patient in any known manner to a location in vessel V where material is to be removed.
- the catheter when introduced over a guidewire, tends to straighten somewhat and follow the guidewire to the location.
- Preformed bends 5 Ip, 5 Id in cooperation with jog 5 Ij urge window 54 against inner wall of vessel V.
- cutter 52 is extended outside of window 54 in a radial direction and catheter 50 is advanced through the vessel with cutter 52 extended to cut atheroma.
- atheroma is directed into interior of catheter by cutter 52.
- the user grasps manipulator 55 and moves it to an appropriate location for manipulating the catheter. The user then locks the manipulator onto shaft 56 and rotates, translates, or both the shaft while handle 58 position remains unchanged.
- Figs. 5 A to 5C illustrate another catheter 60 for use with a manipulator 65.
- a distal portion of the shaft is shaped to provide an apposition force to urge the cutting element against the vessel wall.
- Catheter 60 may be similar to catheter 20 described above but may be any other catheter with a working element, having shaft 66 similar to shaft 26 described above or another shaft, in any case with the addition of jog 6 Ij and continuously decreasing radius curve 61.
- Jog 6 Ij may be similar in construction, materials, and function to jog 5 Ij.
- Catheter 60 is also comprised of working element 62 and window 64 which may be similar in construction, materials, and function as working element 22 and window 24 respectively.
- Working element 62 is positioned at a radially inward position on the shaft so that the working element 62 is urged against the vessel wall when the catheter is positioned within a vessel. Jog 61j and continuously decreasing radius curve 61 cooperate to urge working element 62 into contact with material to be cut in a vessel.
- Manipulator 65 may be comprised of manipulator 10, 30 described above or may be another manipulator. Use of manipulator 65 with catheter 60 is optional.
- Handle 68 may be similar to handle 28 described above but may be any other handle. 5
- Catheter shaft 66 includes jog 6 Ij and continuously decreasing radius curve 61. Continuously decreasing radius curve 61 may be formed by constraining distal portion 66d of catheter shaft 66 in metal molds followed by applying heat to cause distal portion 66d to take the shape of the mold, or other means as are known to those o of skill in the art. Distal portion 66d may curl around at least 90 degrees up to at least 720 degrees. Fig. 5A shows the shaft curling about 360 degrees and Fig. 5B shows the shaft curling about 720 degrees. In other embodiments distal portion 66d curls around 120, 150, 180, 240, 300, 480, or 600 degrees.
- the maximum curve diameter 63 may vary from 3 mm to 50 mm although the maximum curve diameter may be5 outside this range depending upon the particular application. In one embodiment the maximum curve diameter is 10 to 12 mm. In other embodiments the maximum curve diameter is 4, 6, 8, 15, 20, 25, 30, or 40 mm.
- the continuously decreasing radius curve 61 may be0 comprised of a number of discrete preformed bends (not shown).
- the number of sections of decreasing radius may vary.
- catheters having from 2 to 100 sections are contemplated.
- the catheter may have 4, 6, 8, 10, 15, 20, 40, 60, 75, or 100 sections.
- catheter has an infinite number of sections as disclosed by the 5 continuously variable embodiment of Figs. 5A to 5C.
- the continuously decreasing radius is intended to provide a relatively uniform apposition force over a range of vessel diameters.
- the actual apposition force may vary considerably during use since vessel geometry and size vary considerably from patient to patient; however, the shape of the shaft tends to provide a0 uniform force over a range of vessel sizes.
- the catheter is introduced over a guidewire into the patient in any known manner to a location where material is to be removed.
- the catheter when introduced over a guidewire, tends to straighten somewhat and follow the guidewire to the location.
- Curve 61 in cooperation with jog 6 Ij urge window 64 against inner wall of vessel V.
- cutter 62 is extended outside of window 64 in a radial direction and catheter 60 is advanced through the vessel with cutter 62 extended to cut atheroma.
- atheroma is directed into interior of catheter by cutter 62.
- the user grasps manipulator 65 and moves it to an appropriate location for manipulating the catheter. The user then locks the manipulator onto the shaft 66 and rotates, translates, or both the shaft while handle 68 position remains unchanged.
