Abstract: An implantable device (1) for injecting and/or drawing fluid either in an organ or vessel of the body of a human or animal patient and the device comprising a housing (2) with a chamber (2A) connected to a catheter, the catheter is connected either to the organ or vessel or to the compartment. The housing (2) has a proximal wall (4) and a distal wall (5) between which a lateral wall extends. The housing (2) has a puncture area (7) able to be pierced by a hollow needle (14) for injecting and/or drawing fluid in the chamber (2A). The puncture zone (7) extends on the proximal wall (4) and the lateral wall.

Abstract: An implantable device (1) 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, said device (1) comprising a housing (2) within which there is formed a chamber (2A) designed to be connected to a catheter (3), said catheter (3) itself being designed to be connected either to said organ or vessel or to said compartment, the housing (2) comprising a proximal wall (4) and a distal wall (5) with a side wall (6) extending between them, said housing (2) including a puncture zone (7) designed to be capable of being pierced by a hollow needle (14) in order to inject and/or extract fluid into or from the chamber (2A), the device being characterized in that said puncture zone (7) is shaped so as to extend simultaneously at least over the proximal wall (4) and the side wall (6). The invention also relates to implantable sites for injecting and/or extracting fluid.

Abstract: An implantable device (1) for injecting and/or drawing fluid having a housing (2) with a chamber (2A) formed therein. The housing (2) includes a proximal wall (4) and a distal wall (5) between which a side wall extends, and an aspiration zone (7) designed to be perforated by a hollow needle for injecting and/or drawing fluid into the chamber (2A). The aspiration zone (7) extends simultaneously on the proximal wall (4), the side wall and the distal wall (5). The device (1) has a shield (13) made of a material not perforable by a hollow needle inside the chamber (2A) to prevent the housing (2) from being perforated by a hollow needle.
