First Claim
Patent Images
1. A medical device, comprising:
- an elongated tubular member having a proximal segment, a distal segment, and an inner lumen disposed at least partially therethrough, the distal segment configured to radially expand when axially compressed; and
a dilator tip insertable at least in part within the distal segment.

Abstract
Devices and systems for retrieving an intravascular device within a body lumen are disclosed. The retrieval device may comprise an elongated tubular member having a relatively stiff proximal segment, an expandable distal segment, and an inner lumen disposed about a guidewire. The distal segment may include a braid configured to expand when axially compressed. A dilator tip operatively coupled to the elongated tubular member and guidewire may be used to track the retrieval device through the body.

31. A system for retrieving an intravascular device disposed within a body lumen, comprising:
-
an embolic protection filter disposed about an elongated wire;
a retrieval device configured to radially expand and encompass the intravascular filter therein, said retrieval device comprising an elongated tubular member having a proximal segment, a distal segment, and an inner lumen adapted to slidably receive the elongated wire; and
a dilator tip insertable at least in part within the distal segment, said dilator tip configured to engage a stop disposed about the elongated wire.
