Catheter with locking device
First Claim
1. A catheter, comprising:
- a first distal shaft section having a first distal drainage lumen extending therethrough, and a first inflation lumen extending through a wall of the first shaft section;
an elastic sleeve bonded to a distal portion of the first shaft section in circumferential zones defining a cavity beneath the sleeve communicating with the first inflation lumen;
a proximal portion comprising a second proximal shaft section having a second drainage lumen extending therethrough, a hollow connector defining a continuation of the second drainage lumen, a side arm having a valve, and a second inflation lumen extending through the side arm from the valve and through the second shaft section to a distal end of the proximal portion; and
means for releasably locking the first shaft section to the proximal portion while establishing communication between the first and second drainage lumens and between the first and second inflation lumens, wherein the locking means comprises, a body member having a first tubular section extending through the body member and having opposed ends projecting from the body member, said opposed ends of the first tubular section being receivable in the first and second inflation lumens, a second tubular section extending through the body member and having opposed ends projecting from the body member, said opposed ends of the second tubular section being receivable in the first and second drainage lumens, and means for gripping an outer surface of the first and second shaft sections.

Abstract
A catheter comprising, a first distal shaft section having a first distal drainage lumen extending therethrough, and a first inflation lumen extending through a wall of the first shaft section. The catheter has an elastic sleeve bonded to a distal portion of the first shaft section in circumferential zones defining a cavity beneath the sleeve communicating with the first inflation lumen. The catheter has a proximal portion comprising a second proximal shaft section having a second drainage lumen extending therethrough, a hollow connector defining a continuation of the second drainage lumen, a side arm having a valve, and a second inflation lumen extending through the side arm from the valve and through the second shaft section to a distal end of the proximal portion. The catheter has a device for locking the first shaft section to the proximal portion while establishing communication between the first and second drainage lumens and between the first and second inflation lumens.
