Implantable catheter means
First Claim
1. Implantable catheter means comprisinga capsula (10) having a cavity (12), a bottom wall (13), a peripheral wall (14) and a top wall (15) pierceable by a needle,a connecting piece (22) laterally projecting from the peripheral wall (14) of the capsula (10),a catheter (11) insertable into the connecting piece (22),an elastomeric clamping member (30) coacting with the connecting piece (22) in order to fix and seal the catheter (11) relative to the connecting piece (22),a pressure member (26) adapted to be joined to the connecting piece (22) and encompassing the catheter (11) to press it axially against the clamping member (30) which will be radially deformed accordingly thus sealing the passage of the catheter through the connecting piece (22),the connecting piece (22) containing an internal thread (23) into which an external thread of the pressure member (26) may be screwed,a rigid tubular support canula (24) which supports from the inside at least the section of the catheter (11) surrounded by the clamping member (30), andthe support canula (24) being secured to the connection unit with a fixation section (24a) and wherein it unsupportedly projects outwardly relative to the connection piece (22) towards the free end of and coaxially to the latter.

Abstract
The implantable catheter means comprises a capsula (10) having a pierceable top wall (15). A catheter (11) extending into a cavity (12) of said capsula (10) is fixed thereto by an elastomeric clamping member (30) arranged inside a connecting piece (22) which has an internal thread (23) engaged by an external thread of a pressure member (26). By turning the pressure member (26), the clamping member (30) is deformed to press against the periphery of the catheter to fix it and to seal it relative to the capsula (10). The lateral dimensions of the capsula (10) are not increased by the connecting piece (22). The catheter coupling may be easily tightened and released, and it safely prevents the catheter from being extracted.
