Abstract
Balloon catheters and methods of making and using the same. A balloon catheter may include a catheter shaft and a balloon coupled thereto. A traction member may be coupled to the balloon catheter adjacent the balloon and may extend along a portion or all of the length of the balloon. The traction member can improve traction between the balloon and a target site.
Claims12
A balloon catheter, comprising:
- an elongate shaft;
- a balloon coupled to the shaft, the balloon having an outer surface, a proximal end, and a distal end;
- and
- a wire extending substantially parallel to a longitudinal axis of the catheter along the outer surface of the balloon, the wire having a gripping region defined by a helical winding of the wire for facilitating gripping or reducing slippage disposed along the outer surface of the balloon, the wire having a proximal end attached directly to the shaft adjacent the proximal end of the balloon and a distal end attached directly to the shaft adjacent the distal end of the balloon.

A balloon catheter, comprising:
- an elongate shaft having a length, wherein a guidewire lumen is defined along at least a portion of the length of the shaft;
- a balloon coupled to the shaft, the balloon having an outer surface, a proximal end, and a distal end, and an inflatable portion between the proximal end and the distal end;
- and
- a wire having a surface that facilitates gripping or reduces slippage attached to the balloon catheter and extending along the outer surface of the balloon, the wire having a proximal end attached to the balloon catheter adjacent the proximal end of the balloon and a distal end attached to the balloon catheter adjacent to the distal end of the balloon and the wire extending substantially parallel to a longitudinal axis of the catheter along the outer surface of the balloon;
- wherein the distal end of the wire is attached to the catheter shaft at a location distal of the inflatable portion of the balloon;
- and
- wherein the surface is defined by a helical winding of the wire such that a series of windings form a series of peaks.

A balloon catheter, comprising:
- an elongate shaft having a length, wherein a guidewire lumen is defined along a portion of the length of the shaft;
- a balloon coupled to the shaft, the balloon having an outer surface, a proximal end, and a distal end;
- and
- a nickel-titanium alloy wire external to the balloon and extending substantially parallel to a longitudinal axis of the catheter along the outer surface of the balloon and attached to the shaft, the wire includes a gripping region defined by a helical winding of the wire such that a series of windings form a series of peaks for facilitating gripping or reducing slippage and the wire having a proximal end attached to the shaft adjacent the proximal end of the balloon and a distal end attached to the shaft adjacent to the distal end of the balloon.
