Catheter shaft having distal support
First Claim
1. A catheter comprising:
- an inflatable balloon having a proximal end, a distal end, and an inflation cavity therebetween;
a catheter shaft having the inflatable balloon affixed proximate a distal end thereof, the catheter shaft having an inflation lumen fluidly connected to the balloon inflation cavity and a guidewire lumen extending through the balloon cavity within a tubular member which is affixed to the inflatable balloon proximate the distal end; and
a reinforcing sleeve, having a proximal portion and a distal portion with a lumen extending therethrough, wherein the distal portion of the reinforcing sleeve extends into the inflation cavity with at least a portion of the tubular member slidably disposed through the lumen of the reinforcing sleeve and the proximal portion of the reinforcing sleeve is fixed relative to the catheter shaft and disposed in the catheter shaft inflation lumen.

Abstract
A catheter comprising an inflatable balloon having a proximal end, a distal end, and an inflation cavity therebetween, a catheter shaft having the inflatable balloon affixed proximate a distal end thereof, the catheter shaft having an inflation lumen fluidly connected to the balloon inflation cavity. A guidewire lumen extends through the balloon cavity within a tubular member which is affixed to the inflatable balloon proximate the distal end. A reinforcing sleeve, having a proximal portion and a distal portion with a lumen extending therethrough, wherein the distal portion of the sleeve extends into the inflation cavity with at least a portion of the tubular member slidably disposed through the lumen thereof and the proximal portion is fixed relative to the catheter shaft and disposed in the catheter shaft inflation lumen.

11. A catheter comprising:
-
a guidewire tube having a distal end, a proximal end, a lumen therebetween, and an outer surface; an outer tube disposed over the guidewire tube, the outer tube having a distal end, a proximal end and an inner surface defining a lumen therebetween; a balloon having a distal waist sealingly fixed to the guidewire tube, a proximal waist sealingly fixed to the outer tube, and an inflation cavity therebetween; and a reinforcing sleeve having an outer surface attached to the inner surface of the outer tube and extending distally into the inflation cavity; wherein the guidewire tube is slidably disposed within the reinforcing sleeve. - View Dependent Claims (12, 13, 14)

15. A catheter comprising:
-
a first elongate member having a proximal end, a distal end, and a lumen therebetween; a second elongate member partially disposed in the lumen of the first elongate member having a proximal end, a distal end, and a lumen therebetween; a third elongate member disposed on the second elongate member, the third elongate member having a distal end, a proximal end, and a lumen therebetween; and an inflatable balloon member disposed on the second elongate member, the inflatable balloon member having a distal end, a proximal end, and a lumen therebetween; wherein the distal end of the inflatable balloon member is sealingly connected to an outer surface of the second elongate member and wherein a proximal portion of the inflatable balloon member is sealingly connected to a first distal portion of the first elongate member; wherein the third elongate member extends from a point proximal the distal end of the first elongate member to a point distal the proximal end of the balloon; wherein a portion of the third elongate member proximate the balloon is fixed to a distal portion of the first elongate member; and wherein the second elongate member is slidably disposed within the third elongate member. - View Dependent Claims (16, 17, 18, 19, 20, 21)
