Abstract
Abstract An instrument for subcutaneously inserting an injection reservoir attached to an inflatable prosthesis by means of an elongated fluid conduit (32) is disclosed. The instrument (10) has a hollowed end (12) which holds the injection reservoir (30) to be inserted in a mating, releasable fashion and that end is attached to a handle for guiding the hollowed end (12) to the desired site. Desirably, but optionally, the end of the handle of the instrument is provided with a shaped tapered portion (17) to act as a dilator to create a subcutaneous pocket prior to insertion of the injection reservoir.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
147 words
An instrument for the subcutaneous placement of a self-sealing injection reservoir having a hollow interior which communicates with the interior of an implantable, inflatable prosthesis by means of an elongated fluid conduit, said instrument comprising an elongated member having a first hollowed end having a recess which receives the injection reservoir in a mating, releasable relationship and an opposite second end which serves as a handle means for guiding the first end subcutaneously into the body, said first end being of an elongated, substantially tapered configuration with an edge shaped to permit the first end to push aside tissue ahead of the first end when it is inserted subcutaneously and thereby carry the reservoir to the desired subcutaneous site, said first end blending in with the surface of the reservoir to permit the first end along with the reservoir to be smoothly inserted subcutaneously into the body.
Claim 2
Dependent Claim
147 words
An instrument for the subcutaneous placement of a self-sealing injection reservoir having a hollow interior which communicates with the interior of an implantable, inflatable prosthesis by means of an elongated fluid conduit, said instrument comprising an elongated member having a first hollowed end having a recess which receives the injection reservoir in a mating, releasable relationship and an opposite second end which serves as a handle means for guiding the first end subcutaneously into the body, said first end being of an elongated, substantially tapered configuration with an edge shaped to permit the first end to push aside tissue ahead of the first end when it is inserted subcutaneously and thereby carry the reservoir to the desired subcutaneous site, said first end blending in with the surface of the reservoir to permit the first end along with the reservoir to be smoothly inserted subcutaneously into the body.
Claim 3
Dependent Claim
62 words
The instrument as claimed in claim 1 wherein said first end further contains a channel through which said fluid conduit is passed before the instrument carrying the reservoir is inserted subcutaneously, said channel being placed on the first end at the rear of the reservoir being inserted such that the channel is at the rear of the first end facing the handle.
