Foley catheter assembly
First Claim
1. A catheter assembly comprising a shaft having a drainage lumen and an inflation lumen mateable with a connector with a generally axially disposed bore therethrough and an inflation side arm, said connector comprising:
- an inflation means which provides fluid communication between said inflation side arm and said inflation lumen in said shaft, in any rotational orientation of said shaft; and
a rotatively enactable sealing means disposed about said bore for securing said shaft in said bore of said connector and for preventing leakage of fluid from said inflation means;
said sealing means comprising at least one annular channel having means for the receipt of adhesive, said channel disposed in said bore radially outwardly of said shaft.

Abstract
A shaft and a connector with a side arm which when assembled comprise a catheter. The connector has an inflation lumen in its side arm and an axial bore through the body of the connector, the inflation lumen and the bore being in fluid communication.
The bore has three annular channels therein. Two of the channels are arranged to receive adhesive through the wall of the connector, and the third channel is intermediate the other two is in fluid communication with the inflation lumen of the side arm. The shaft has a drainage lumen and an inflation lumen therein. A pair of openings to the inflation lumens, are disposed in the shaft, corresponding to two of the channels in the connector.
Adhesive injected into the outer channels bonds the shaft to the connector and seals the proximalmost orifice of the inflation lumen in the shaft. The other opening provides fluid communication between the inflation lumen of the shaft and the inflation lumen of the side arm.
