Abstract
Apparatus for passing a blocked vein, including: (a) an intravascular catheter body defining at least one lumen; (b) a radially expandable anchor at a distal end of said catheter; and (c) a penetration tool sized and shaped to be delivered by the lumen to a point distal of the expandable anchor, the penetration tool including a tip and configured for being pushed through venous blockage more than one week old and present with a young's modulus greater than 1 MPa. Optionally, the penetration tool tip comprises a sharpened tip. Optionally or additionally, the penetration tool tip is controllably bendable.
Claims26
An apparatus for passing a blocked blood vessel, comprising:
- (a) an intravascular catheter body defining at least one lumen;
- (b) a radially expandable anchor at a distal end of said catheter;
- and
- (c) a penetration tool sized and shaped to be delivered by said at least one lumen to a point distal of said radially expandable anchor, said penetration tool including a tip and configured for being pushed through venous-a blood vessel blockage more than one week old and having a young's modulus greater than 1 MPa;
- wherein said apparatus further comprises an axially slidable sheath in said at least one lumen and outside said penetration tool and configured to shape said penetration tool;
- wherein said penetration tool is bendable at a bend location at a distal end thereof such that said tip is steerable;
- and wherein said penetration tool is configured to only bend in one direction.
