Abstract
A catheter system that is actuatable to a deployed state and includes a catheter body and a dilator positioned at least partially within the lumen of the catheter. A distal end of the dilator can be releasably connected to a distal tip of the catheter body. The dilator can be retractable to expand and invert the distal tip and form a funnel shape in the deployed state.
Claims18
A catheter system actuatable to a deployed state, comprising:
- a catheter body comprising a lumen;
- and
- a dilator positioned at least partially within the lumen, a distal end of the dilator releasably connected to a distal tip of the catheter body, the dilator being retractable to expand and invert the distal tip such that the distal tip forms a funnel shape in the deployed state;
- the distal tip comprising:
- a proximal segment;
- and
- a distal segment extending from the proximal segment, the distal segment being substantially flexible, the distal segment further comprising a proximal end and a distal end, the proximal end comprising a first mating surface;
- a pull ring adjacent to the distal end of the distal segment, the pull ring comprising a second mating surface,
- wherein the first mating surface and the second mating surface are configured to snap lock together.
6 more elements
A method of inverting an expansile catheter in a blood vessel, comprising:
- advancing the catheter to a target site;
- retracting, by a dilator at least partially within a lumen of the catheter, a pull ring approximate a distal tip of the catheter, causing the distal tip to expand and invert to a funnel shape, the pull ring and a proximal end of the distal tip each comprising mating surfaces configured to snap lock together.
