in the cammla handle. The interlocking devices are a spring biased pin radially entering a receiving socket, and a notched projection which extends into the receiving socket. The pin has a ramped portion, and the notched projection has a rounded or conical tip which rides down the ramped portion of the pin and thereby pushes the biased pin radially out of the socket during assembly of the hollow cannula with the trocar. The assembled handles provides a smooth upper surface which fits comfortably in a palm and a lower gripping surface around which fingers easily wrap. The interlocking devices hold the handles securely together keeping the trocar within the cannula during puncture, but are easily separated thereafter.
(42, 52, 62),which are associated with the connection points of the inner wrapping. The two wrappings are permeable to gas at least some regions. In accordance with the invention the container has a second application apart from its protective function: for example, in the case of a hybrid prosthesis for vascular replacement, to perform the charging of the prosthesis with the patient’s own endothelial cells in the container.

5385229 CONTAINER FOR THE PACKAGING OF A HOLLOW ENDOPROSTHESIS Bittmann Pete; Tanner Fredy; Muller-Glauser SWITZERLAND Assigned to Sulzer Medizinaltechnik AG The container for packing hollow endoprostheses (8) comprises two germ-proof wrappings (1, 2). In accordance with the invention the inner wrapping (1) consists of a water-tight wall (10, 11) and various connection points (40, 50, 60). At least two of the connection points (40) are provided as access into the cavity of the prosthesis (8) and one is provided as an outlet (50) for liquids for treating the prosthesis. The outer wrapping (2) comprises through-pieces

The present invention concerns a spinal fluid driven artificial organ device and methods for its use. The device 10 has a tripartite chamber with three sections. A micropore filter B separates chamber section 1 from chamber section 2 and a micropore filter C separates chamber section 2 from chamber section 3. CSF enters chamber section 1 via an inlet tube Tl and an one way value Vl. Micropore filter B allows entry of CSF into chamber section 2 but does not allow exit of any cells from chamber section 2 into chamber section 1. Micropore filter C allows free passage of CSF from chamber section 2 into chamber section 3 and prevents any cells in chamber section 2 from entering chamber section 3. The CSF flow exits chamber section 3 via an one way valve V2 and all outlet tube T2. The outlet tube T2 delivers the CSF to the desired location.
