Definitions
- This invention relates to a method and device for facilitating the delivery of components along guidewires to branches of a tubular system. It has particular application for the percutaneous treatment of vascular and non-vascular disease, and in particular in the use of balloon angioplasty and for the deployment of balloon-expanded or self- expanding stents.
- Balloon angioplasty or deployment of stents for lesions at a bifurcation may require that the component (balloon angioplasty or stent) be advanced into position over two guidewires, each of which is positioned in a separate downstream branch vessel. It is important that, when the guidewires are positioned prior to the component delivery, the guidewires do not become entangled or wrapped around each other.
- a guidewire positioning device for facilitating the delivery of components along guidewires to two or more branches of a tubular system, said device including a shaft and two or more guidewire lumina interconnected to and parallel to one another, each said lumen having an open distal end and an open proximal end on said shaft.
- the tubular system may be a vascular system and the device may be adapted for facilitating the delivery of components used in the management of vascular disease.
- the device may be adapted for the delivery of stents to lesions at a bifurcation.
- a method of positioning guidewires for the delivery of components to two or more branches of a tubular system including the steps of: engaging a first guidewire through a first guidewire lumen of a guidewire positioning device, before or after advancing the first guidewire along the tubular system and into a first branch; advancing one or more further guidewires along one or more further guidewire lumen, interconnected to and parallel to the first guidewire lumen, of the guidewire positioning device, to a distal end of said further guidewire lumen; advancing the guidewire positioning device, with the engaged further guidewire or guidewires, along the first guidewire by means of a shaft of the guidewire positioning device, until said distal end of the or each further guidewire lumen is adjacent the branching of the tubular system; rotating the shaft of the guidewire positioning device so that the distal end of the or each further guidewire lumen is adjacent a second branch of the tubular system; and advancing the, or one of the, further guidewires into the second
- a method of treating a lesion of lesions at a bifurcation in a blood vessel including the steps of: engaging a first guidewire on a first guidewire lumen of a guidewire positioning device, before or after advancing the first guidewire along the blood vessel and into one down stream branch vessel; advancing a second guidewire to a distal end of a second guidewire lumen, interconnected to and parallel to the first guidewire lumen, of the guidewire positioning device; - securing the second guidewire in relation to the guidewire positioning device; advancing the guidewire positioning device, with the secured second guidewire, along the first guidewire by means of a shaft of the guidewire positioning device until the distal end of the second guidewire lumen is at the bifurcation; rotating the guidewire positioning device, if necessary, to align the distal end of the second guidewire lumen with the second branch vessel; advancing the second guidewire into the second branch vessel; withdrawing the guidewire positioning device along both the first and second
- Figure 1 Shows a longitudinal section of a guidewire positioning device of the invention in one preferred form
- Figure 2 shows a perspective view of the device of Figure 1 with a guidewire engaged in the second lumen;
- Figure 3 shows an enlarged longitudinal section of the distal end of the device of Figure 2;
- Figure 4 shows longitudinal sections of alternative configurations of the joins between the shaft and the two guidewire lumina of a guidewire positioning device of the invention.
- Figure 5 shows a cross section through the manipulation aid of the device of Figures 1 and 2, in one preferred form.
- a guidewire positioning device 1 of the invention has two guidewire lumen which are interconnected to one another and parallel.
- the first guidewire lumen 4 has an open distal end 1 5 and an open proximal end 1 6.
- the second guidewire lumen 5 has an open distal end 1 7 and open proximal 1 8.
- a radio- opaque marker 8, 9 may be positioned at or close to the distal end 1 5, 17 so that the position of the distal ends may be determined through fluoroscopy.
- the second guidewire lumen 5 may have a distal end 1 7 a short distance (approximately 1 0mm) proximal to the distal end 1 5 of the first guidewire lumen 4.
- the second guidewire lumen 5 might extend to the distal end 1 5 of the first guidewire lumen 4, or it may end distally a considerable distance more than 10mm from the distal end 1 5 of the first guidewire lumen 4.
- the distal end 1 7 of the second guidewire lumen 5 may have an oblique bevelled shape 10, as best seen in Figure 3. This shape aids advancement of the guidewire positioning device 1 into position in the vessel, and also aids advancement of a guidewire from the second guidewire lumen 5 into a branch vessel.
- the radio-opaque marker 9 at or close to the distal end 1 7 of the second guidewire lumen 5 may have a symmetrical or asymmetrical configuration.
- An asymmetrical shape, as shown in Figure 3 may aid orientation of the second guidewire lumen 5 in the vessel under fluoroscopy.
- the guidewire lumen may have a double over-the- wire, double monorail, or combination over-the-wire/monorail configuration.
- a double monorail configuration would require a separate proximal catheter shaft (as in Figures 1 and 2) .
- proximal catheter shaft at the proximal end of this shaft 3 there may be a longitudinally enlarged hub 2, or manipulation aid, to aid catheter manipulation.
- This hub 2 may have a longitudinal recessed groove 7 into which a guidewire may be positioned, as shown in Figures 2 and 5. Slotting a guidewire 6 in place in this groove 7 holds the guidewire in position in relation to the guidewire positioning device, as the device is advanced, withdrawn or rotated to manipulate the distal end of the device.
- Figure 5 shows that this groove 7 may include ribbing 1 9 or other means, to grip the guidewire 6.
- one or more additional parallel lumina may be included for use in applications where a parent vessel or tube branches into more than two branches or where more than one separate component is required to be delivered to one particular branch.
- Figures 1 and 3 show a guidewire positioning device 1 of the invention in a monorail version.
- the proximal ends 1 6, 1 8 of the guidewire lumina 4, 5 are shown off set in this embodiment, with the proximal end 1 6 of the first guidewire lumen 1 5 proximal of the proximal end 1 8 of the second guidewire lumen 5, consistent with the embodiment of Figure 4B.
- the embodiment of Figure 4A shows the two proximal ends 1 6, 1 8 at the same proximal position in relation to the shaft 3.
- Figure 4 also shows of the interconnection between the shaft 3 and the lumina 4, 5.
- the guidewire positioning device of the invention including the hub 2, shaft 3 and lumina 4, 5 may be integrally formed from plastics material.
- one method of use after deployment of the guide catheter, is to advance a first guidewire via the first guidewire lumen 4 and along the guide catheter, across the bifurcation lesion and into one downstream branch vessel.
- the first guidewire may be advanced along the guide catheter first and the first guidewire lumen then engaged on the first guidewire via its proximal end.
- a second guidewire is then positioned in the second guidewire lumen 5 of the device and advanced until the distal end of the guidewire is close to or adjacent the distal end 1 7 of the second guidewire lumen 5.
- the proximal portion of the second guidewire is then slotted into the recessed groove 7 in the hub 2 at the proximal end of the catheter shaft 3, to hold that guidewire in position as the guidewire positioning device 1 is subsequently manipulated.
- the guidewire positioning device 1 and the second guidewire are then advanced as a unit along the first guidewire already positioned in the vessel.
- the guidewire positioning device 1 is advanced until the distal end 1 5 of the first guidewire lumen 4 is just beyond the bifurcation" and the distal end 1 7 of the second guidewire lumen 5 is almost at the bifurcation. It will be appreciated that in an embodiment of the device in which the distal ends of the guidewire lumina are adjacent one another then both will be positioned substantially at the bifurcation.
- the guidewire positioning device 1 is then rotated by manipulation of the hub 2 so that the bevelled, marked distal end 1 7 of the second guidewire lumen 5 is aligned with the other branch vessel which does not yet have a guidewire.
- the second guidewire is then released from the hub and steered into the second branched vessel. Once the second guidewire is in position the guidewire positioning device may be withdrawn, with both guidewires kept in position, one in each downstream branch vessel.
- Angioplasty balloons or stents can then be advanced over one or both guidewires to treat the lesion in the knowledge that the guidewires are not entangled or wrapped around each other.
- the guidewire positioning device 1 of the invention provides a relatively simple device which can be used to facilitate the delivery of guidewires to branched regions of a tubular system, such as blood vessels, to enable the delivery of components required in those branches along the guidewires, without the risk of complications associated with multiple guidewires becoming wrapped or entangled with one another.
