1. An implantable access device to access a vascular system of a human or animal body, particularly a subcutaneously implantable access port, comprising:
a port body with at least one outlet opening connected or connectable to a catheter to access the vascular system of the human or animal body;
a needle entrance with at least one inlet opening to receive a needle, wherein the needle entrance is connected to the port body and pivotably movable relative to the port body between a first, unactuated operating condition and a second, actuated operating condition; and
a flexible socket forming an external portion of the port, wherein the flexible socket is arranged between the port body and the needle entrance and at least covers an area or volume where the needle entrance moves relative to the port body to prevent tissue growth in the area or volume where the needle entrance moves relative to the port body,
wherein the flexible socket at least covers the area or volume where the needle entrance moves relative to the port body without covering the at least one inlet opening to receive the needle, and
wherein, during movement of the needle entrance relative to the port body between the first, unactuated operating condition and the second, actuated operating condition, the flexible socket is deformed by the movement of the needle entrance relative to the port body to push tissue away from the implantable access device.
 
10. An implantable access device to access a vascular system of a human or animal body, particularly a subcutaneously implantable access port, comprising:
a port body with at least one outlet opening connected or connectable to a catheter to access the vascular system of the human or animal body;
a needle entrance with at least one inlet opening to receive a needle, wherein the needle entrance is connected to the port body and movable relative to the port body between a first, unactuated operating condition and a second, actuated operating condition;
a receptacle movably connected to the port body, wherein the needle entrance is connectable to the receptacle such that the receptacle and the needle entrance are movable relative to the port body; and
a flexible socket forming an external portion of the port, wherein the flexible socket is arranged between the port body and the needle entrance and at least covers an area or volume where the needle entrance moves relative to the port body without covering the at least one inlet opening to receive the needle,
wherein the flexible socket prevents tissue growth in the area or volume where the needle entrance moves relative to the port body, and
wherein, during movement of the needle entrance relative to the port body between the first, unactuated operating condition and the second, actuated operating condition, the flexible socket is deformed by the movement of the needle entrance relative to the port body to push tissue away from the implantable access device.
