A femoral hip joint spacer. The spacer has a prosthesis body with a ball head, a neck, a stem and an anchoring sleeve which encloses the stem on a proximal side of the stem with a circumferential fastening area, irrigation liquid inlet and outlet openings in the body surface, at least one irrigation liquid discharge opening on a distal side of the stem and at least one irrigation liquid intake opening on the ball head or on the neck. The discharge opening is connected in a liquid-permeable manner to the inlet opening but not to the outlet opening and the intake opening is connected inside the prothesis body in a liquid-permeable manner to the outlet opening but not to the inlet opening. A cavity open on two sides is formed inside the anchoring sleeve and connects a proximal side to a distal side of the sleeve in a liquid-permeable manner.

A tissue expander having an integrated drain includes an outer shell having an opening and one or more drainage holes. An injection port is disposed in the opening of the shell and forms a fluid-tight seal with the shell. The injection port includes a needle guard having a needle guard base with a top surface, and a barrier membrane that overlies the top surface of the needle guard base. The barrier membrane defines an inflation chamber located between the top surface of the needle guard base and a bottom surface of the barrier membrane, and a drainage chamber overlying a top surface of the barrier membrane. The tissue expander includes one or more inflation ports that are in fluid communication with the inflation chamber for inflating and deflating the outer shell with a first fluid. A drainage conduit is in fluid communication with and extends between the drainage chamber and the one or more drainage holes for draining a second fluid from outside the shell.

A tissue expander having an integrated drain includes a shell having an opening and one or more drainage holes, and an injection port disposed in the opening of the shell and forming a fluid-tight seal with the shell. The injection port includes a needle guard having a needle guard base with a top surface. The injection port includes a moveable barrier membrane overlying the top surface of the needle guard base. The moveable barrier membrane is moveable between a first position for inflating and deflating the shell with a first fluid and a second position for draining a second fluid from outside the shell. A magnet is coupled with the moveable barrier membrane, and a compressible spring is connected with the magnet. The compressible spring is compressed for storing energy as the moveable barrier membrane moves from the first position to the second position.

A joint implant device is presented. In embodiments, the device may include a central cylindrical anchor with a sharp distal end and a substantially flat proximal portion. In embodiments, the anchor may be provided with at least one longitudinally extending microtube, to convey at least one of blood and nutrients from the distal end to a proximal end. In embodiments, there may be a plurality of microtubes, each having an intake in the distal end and multiple outflows in the proximal portion. In some embodiments the device may include an eyelet through which a suture may be provided for additional fixation into a joint.

Disclosed herein is a temporary knee spacer system for the temporary replacement of a knee joint, which is designed for the interim phase of two-stage septic revisions of knee joint total endoprostheses. The knee spacer system can be used in particular with two-phase septic revisions with which two or more microbial germs are the cause of an infection of the knee joint total endoprosthesis and the surrounding tissue.

This disclosure describes a surgical implant device comprising a body that includes a porous material forming at least a portion of the body, wherein the porous material is configured to promote bone ingrowth and is porous to a fluid. In addition, one or more fluid channels are formed in the body. The one or more fluid channels are arranged to define a fluidic path that exits into the porous material.
