Abstract:
1. An implantable device for injecting and/or extracting fluid either into or from an organ or vessel of the body of a human or animal patient, or into or from an inflatable and/or deflatable compartment of a surgical implant, the device comprising: a) a housing having a chamber defined by a proximal wall and a distal wall with a side wall extending therebetween, the housing including a puncture zone designed to be capable of being pierced by a hollow needle in order to inject and/or extract fluid into or from the chamber, the chamber being connectable to a catheter; b) a screen made of a material that is not pierceable by the hollow needle, the screen being disposed within the chamber so that the hollow needle puncturing the proximal wall in the puncture zone is blocked by the screen from extending through the chamber and puncturing the distal wall generally on the housing generally opposite from the site of the proximal wall, wherein the device is adapted to rotate within the organ or vessel once implanted, wherein the distal wall, proximal wall and side walls are puncturable by the hollow needle, wherein the puncture zone is shaped so as to extend simultaneously at least over the proximal wall the side wall, and the distal wall, and, wherein the housing further comprises a frame made of a material that is substantially not pierceable by the hollow needle, the frame having at least one opening, substantially the entire frame being covered by at least one pierceable envelope made of a self- sealing material.
