Crossing occlusions in blood vessels
First Claim
1. A method of facilitating treatment via a vascular wall defining a vascular lumen containing an occlusion therein, the method comprising:
- providing a first intravascular device having a distal portion and at least one aperture;
positioning the distal portion of the first intravascular device in the vascular wall;
providing a reentry device having a body and a distal tip, the distal tip having a natural state and a compressed state;
inserting the distal tip, in the compressed state, in the distal portion of the first intravascular device; and
advancing the distal tip, in the natural state, through the at least one aperture of the first intravascular device.

Abstract
The present disclosure is directed a method of facilitating treatment via a vascular wall defining a vascular lumen containing an occlusion therein. The method may include providing a first intravascular device having a distal portion and at least one aperture and positioning the distal portion of the first intravascular device in the vascular wall. The method may further include providing a reentry device having a body and a distal tip, the distal tip having a natural state and a compressed state and inserting the distal tip, in the compressed state, in the distal portion of the first intravascular device. The method may further include advancing the distal tip, in the natural state, through the at least one aperture of the first intravascular device.
