Abstract
The embodiments disclosed herein relate to balloon catheter assemblies. The balloon catheter assemblies can include a hub, an elongated member, and an inflation balloon. The balloon catheter assemblies can also include a support wire having a proximal end that is longitudinally displaceable within a sleeve that is disposed in the catheter hub. A distal end of the support wire may be coupled to the inflation balloon at one or more positions.
Claims20
A balloon catheter assembly, comprising:
- an elongated member having a lumen extending longitudinally therethrough;
- a hub coupled to a proximal end of the elongated member;
- a support wire disposed within the elongated member;
- and
- an inflation balloon, wherein a distal end of the inflation balloon is coupled to a distal end of the support wire, and wherein the support wire is operatively coupled to the balloon catheter assembly such that the support wire does not exert a longitudinally compressive force on the inflation balloon.
2 more elements
A balloon catheter assembly, comprising:
- an inflation balloon;
- and
- a support wire coupled to the inflation balloon at a coupling portion at a proximal end of the inflation balloon and at a distal end of the inflation balloon, such that the support wire resists longitudinal compression of the inflation balloon.
A method of positioning a balloon catheter assembly, comprising:
- applying a force to displace the balloon catheter assembly within a delivery lumen,
- wherein the force is transferred to or from a support wire such that the support wire does not exert a longitudinally compressive force on an inflation balloon.
