Abstract: An implant with a surface structure on at least a portion of a surface of the implant, wherein the surface structure is selected to facilitate, improve and enhance ingrowth characteristics of the implant. A method of providing an implant with a selected surface structure is encompassed.

Abstract: An injection needle assembly including an injection needle, which can pierce body tissue, and a needle guide, which can be placed on the body tissue and axially stabilizes the injection needle against flexure and cracking.

Abstract: A membrane with at least one passage extending through an elastic material of the membrane, wherein when a cannula is inserted in the passage, the passage is expanded and the elastic material presses against the cannula and surrounds the cannula in a seal, wherein the membrane can be compressed relative to the passage, and wherein, in one embodiment, the passage exhibits a cross-sectional area having a long main axis and a short main axis perpendicular to the long main axis. The invention encompasses a membrane-cannula combination for biological and medical uses, and a membrane-connecting device combination for connecting a fluid guide and a catheter.

Abstract: A cannula, for introduction into a body tissue, the cannula flexible after introduction, and rigid below a critical temperature and flexible above the critical temperature. In a method for the introduction of the cannula into the body tissue, the cannula is cooled to a temperature below the critical temperature and introduced into the body tissue. After being introduced, the cannula is brought to a temperature above the critical temperature by warming and thus becomes flexible.

Abstract: An injection needle, for injection into a body tissue, is flexible in the introduced or post-inserted state and comprises a channel for the introduction of a fluid. The injection needle is at least partly made from at least one material which is rigid in one state and flexible in a second state. Alternatively or concurrently, the injection needle is rigid on application of a force to the needle along the longitudinal direction of a needle longitudinal axis and is flexible on application of a force in the radial direction relative to the needle longitudinal axis.

Abstract: Catheter system consisting of a sleeve, a catheter and a membrane partially arranged in the sleeve, which can be fixed in a skin passage unit in such a way that the catheter protrudes from the skin passage unit towards the interior of the body, wherein the individual components of the catheter system are inseparably connected to one another.

Abstract: Implantable cylindrical device for connecting a hose arranged outside of the human or animal body to a hose arranged inside of the said body, wherein an anchoring plate falling away peripherally from the skin surface is arranged around the cylindrical device. This allows the skin to unroll over the anchoring plate subject to a tilting moment of the port body.
