Abstract
An anti-reflux drainage device includes an elongated member defining a lumen, and a valve disposed along the elongated member. The valve can include one or more lumens in fluid connection with the lumen of the elongated member, a socket, a shaft disposed in the socket, and a stopper connected to the shaft that occludes the second lumen when exposed to retrograde pressure. Another such device includes an elongated member and a ball valve. The ball valve can include a seat and a shoulder defined by the elongated member, and a ball disposed in the elongated member between the seat and shoulder that occludes lumen when exposed to retrograde pressure.
Claims39
A medical device for assisting in the drainage of fluid from a body cavity comprising:
- an elongated member comprising a distal end and a proximal end and defining a first lumen extending therebetween;
- and
- a valve disposed at the proximal end of the elongated member, the valve comprising:
- a tube defining a second lumen in fluid connection with the first lumen, the tube comprising a first end connected to the proximal end of the elongated member, and a socket;
- a shaft at least partially disposed in the socket;
- and
- a stopper connected to the shaft that occludes the second lumen when exposed to retrograde pressure.
A valve for preventing reflux of fluids in a medical device comprising:
- a tube defining a lumen having a first end and a second end, and a socket;
- a shaft at least partially disposed in the socket;
- and
- a stopper attached to the shaft that occludes the lumen when exposed to retrograde pressure.
A method of assisting the drainage of fluid from a body cavity, the method comprising:
- providing a medical device comprising:
- an elongated member comprising a distal end and a proximal end and defining a first lumen extending therebetween;
- and
- a valve disposed at the proximal end of the elongated member, the valve comprising:
- a tube defining a second lumen in fluid connection with the first lumen, the tube comprising a first end connected to the proximal end of the elongated member, and a socket;
- a shaft at least partially disposed in the socket;
- and
- a stopper connected to the shaft that occludes the second lumen when exposed to retrograde pressure;
- and
- inserting said device into a ureter.
A medical device for assisting in the drainage of fluid from a body cavity, comprising:
- an elongated member comprising a distal end and a proximal end and defining a first lumen extending therebetween;
- a seat defined by the elongated member;
- a shoulder defined by the elongated member proximal to the seat;
- and
- a ball disposed in the elongated member between the seat and the shoulder that occludes the first lumen when exposed to retrograde pressure.
