Patent Images
1. A catheter implantable in a living subject for supplying fluid to a first chamber in the body of the subject and controllably allowing fluid to pass from the first chamber into a second chamber of the subject, the catheter comprising:
- a body adapted for implantation in the subject and having a proximal end and a distal end;
means for mounting said body in the subject with the proximal end adjacent to exterior of the subject and with the body extending into the interior of the subject;
said body having passage means therein leading from a location adjacent the proximal end into the interior of the body;
said passage means having inlet means adjacent said proximal end and outlet means communicating with said first chamber of the subject when the catheter is implanted in the subject whereby a fluid can be passed from the inlet means through the passage means and the outlet means to the first chamber; and
valve means on the body for controlling the flow of the fluid therethrough from the first chamber to the second chamber.
