Port body for the administration of drugs

An implantable device for implantation generally adjacent to a skin surface of a human or animal body for connecting a hose outside the human or animal body to a hose arranged inside the body, said device comprising a generally cylindrical port body and an anchoring plate arranged around the generally cylindrical port body, and extending generally radially therefrom, wherein, when the device is implanted, the anchoring plate extends generally away from the skin surface, further comprising two fins, each fin having a peripheral fin edge, said edges spaced from each other, characterized in that the distance between the two peripheral fin edges is smaller than a cross-sectional diameter of a channel-shaped radial pocket formed by the two fins.

An implantable device for implantation in a human or animal body for connecting an infusion hose generally outside the body to a catheter generally inside the body, the implantable device comprising:

• (a) a generally cylindrical, hollow shaft having an outside aperture and an inside aperture;
• and
• (b) an anchoring plate generally around the shaft, said anchoring plate having a periphery, wherein, when the device is implanted, said anchoring plate is adapted to extend generally toward the interior of the body and said periphery is adapted to be farthest from the exterior of the body, wherein the shaft includes an anchoring part carrying a radially protruding port fin and an anchoring fin, each fin having a periphery fin edge, wherein a radial pocket is formed between the port fin and the anchoring fin, wherein a gap between the peripheral fin edge of the port fin and the peripheral fin edge of the anchoring fin is smaller than a diameter of the radial pocket.

An implantable device for implantation in a human or animal body generally adjacent to the skin for connecting an infusion hose outside the body to a catheter inside the body, the implantable device comprising:

• a port body having a shaft part, an anchoring part, an inlet aperture, and an outlet aperture, wherein the anchoring part comprises a generally radially protruding port fin and an anchoring fin, each fin having a respective peripheral fin edge, said respective peripheral fin edges spaced from each other, and a radial pocket generally between the port fin and anchoring fin, wherein the space between the peripheral fin edges is less than a diameter of the radial pocket.

An implantable device for implantation in a human or animal body generally adjacent to the skin for connecting an infusion hose generally outside the body to a catheter generally inside the body, the implantable device comprising:

• a generally hollow shaft having an outside end and an inside end and an outside opening adjacent to the outside end and an inside opening adjacent to the inside end, said shaft having an anchoring portion including a radial fin and an anchoring fin, and a channel-like pocket between the radial and anchoring fins;
• and
• a generally disc-shaped anchoring plate carried around the shaft in the anchoring portion, said anchoring plate having an annular portion adjacent to the shaft and a peripheral portion, and being curved along its radial extent, whereby, when the device is implanted, the peripheral portion is adapted to be farthest from the skin, wherein the radial fin and anchoring fin each have a respective fin edge, said fin edges spaced from each other, and wherein the pocket has a diameter greater than the space between the fin edges.
