Laser-cut clot puller
View Patent ↗A device for removing blood clots and methods of making and using the same. The clot pulling device may include a first spine, a second spine disposed parallel to the first spine, and a basket disposed between and coupled to the spines. In addition, a pushing member may be coupled to the first spine and extend proximally therefrom.
1. A method for removing clots from a blood vessel, comprising the steps of:
providing a clot pulling device including a first spine having a proximal end, a second spine disposed parallel to the first spine, a pushing member coupled to the proximal end of the first spine and extending proximally therefrom, and a basket disposed between and coupled to the first and second spines;
providing a catheter having a lumen extending therethrough;
advancing the catheter through a blood vessel to a location adjacent an area of interest;
advancing the clot pulling device through the lumen of the catheter to a position distally of the area of interest;
expanding the basket;
entrapping a clot within the basket;
advancing the catheter through a blood vessel to a location adjacent an area of interest includes disposing the clot pulling device in the lumen and advancing the catheter and the clot pulling device through the blood vessel; and
advancing the clot pulling device through the lumen of the catheter to a position distally of the area of interest includes pushing the clot pulling device in the distal direction with the pushing member.
2. The method of claim 1 , wherein the step of advancing the clot pulling device through the lumen of the catheter to a position distally of the area of interest includes advancing the clot pulling device out from a distal end of the catheter.
3. The method of claim 1 , wherein the step of expanding the basket includes applying force in the distal direction to the pushing member.
