DEVICE FOR VASCULAR AND PERITONEAL ACCESS AND A DEVICE FOR HEMODIALYSIS

摘要

An implantable device for venous or peritoneal access including a housing including a void having distal a proximal openings; an insert for insertion through the proximal opening comprising a venous or peritoneal catheter; a valve element mounted in a cylindrical recess of the insert; an extracorporeal coupling member of which a terminal portion can be inserted into a proximal recess of the valve element; one or two conduits extending from the catheter to the proximal end of the coupling member via the valve element and the insert for providing fluid communication, which can be interrupted by rotating the coupling member. The coupling member can be extracted from the recess only in a state of interrupted communication.

1. Device for venous or peritoneal access, comprising:
a housing comprising a void; an insert disposable in the void and removable from it, the insert comprising a first conduit extending from a first distal face thereof disposed intra-corporeally to a bottom face of a recess in a second proximal face thereof disposed extra-corporeally, the faces including an angle α of about 90°; a cylindrical valve member housed in the insert recess, the valve member comprising a first valve conduit extending between the distal end face of the valve member and the bottom face of an oblong radially extending recess in a proximal face of the valve member; a coupling member comprising a portion extending from its distal end of same but positive form as the valve member recess and capable of being inserted into the recess and of being withdrawn from it, the coupling member comprising a first coupling conduit communicating, in an inserted position, with the first valve member conduit; wherein the first valve member conduit is displaceable by rotation of the valve member about its cylinder axis from an open position in which it is in communication with the first insert conduit to a closed position in which it is not or vice versa by rotation of the coupling member.
