Rapid exchange over-the-wire catheter with breakaway feature
First Claim
Patent Images
1. A rapid exchange over-the-wire catheter for use in combination with a guidewire which has been positioned at a target site in a patient'"'"'s body, said catheter comprising:
- a tubular shaft having a proximal end, a distal end, and at least one lumen adapted to receive said guidewire; and
a tear strip longitudinally disposed in said tubular shaft along said lumen from said proximal end toward said distal end for progressively removing said tear strip from said tubular shaft from said proximal end toward said distal end to expose said guidewire and to allow said catheter to be removed from said guidewire while maintaining said guidewire in said desired position.

Abstract
A rapid exchange over-the-wire catheter is disclosed provided with one or more breakaway elements for progressively exposing the guide wire from the proximal end toward the distal end of the catheter in a simple and efficient manner. The breakaway element may be formed as a longitudinally aligned pull strip provided in the catheter guidewire lumen or as one or more linearly arrayed tubular breakaway segments in the catheter shaft or as a combination of both features.

14. A rapid exchange over-the-wire dilation catheter for use in combination with a guidewire, said catheter comprising:
-
a tubular shaft having a proximal end, a distal end, and at least one lumen adapted to receive said guidewire, said tubular shaft being formed with at least one circumferential tear strip disposed between said proximal and distal end of said tubular shaft, said tear strip being operable for disecting a proximal portion of said tubular shaft from a distal portion of said tubular shaft allowing removal of said guidewire form said lumen; and an expandable dilation balloon disposed adjacent to said distal end. - View Dependent Claims (15, 16)
