A method of making a jaw for a biopsy forceps in which a flat strip is formed with a sharpened edge and a tang with a pointed end. The strip is bent to form an open loop, and the tang is bent to extend upwardly into the loop.

Method for making a jaw for a biopsy forceps

A cervical pressary having a central stem with a passage from end to end thereof. A distal retainer is provided at the distal end of the stem, and a proximal retainer at the other end. The retainer are flexible and distensible. They are connected to each other through the stem passage, and are inflatable by fluid injected into them. A leaflet-type fill valve passes through the wall of the proximal retainer. Th fill valve closes when outside pressure is exerted on the leaflets. The fill valve can be physically opened by insertion of a fill tube into it.

Inflatable cerivical pessary

An inflatable implant has a flexible shell that forms an internal lumen. It has a base portion and an envelope portion, with an aperture through the base. A tubing storage shell is in the lumen and attached to the base, forming a peripheral seal with the base around the aperture in the base. A flexible fill tubing is structurally permanently attached to the tubing storage shell, sealed with the aperture in the tubing storage shell and passing freely through the aperture in the base. A substantial length of the fill tubing is stored in the storage shell which can be drawn toward an incision in the skin of the patient so the volume of the implant can be adjusted without directly accessing the shell.

Inflatable implant

An implantation prosthesis, and a composite material for use in constructing this prosthesis. The material is flexible. It has an inner wall, an outer wall, and a foam layer between the walls in adherent surface-to-surface contact. The walls are made of a flexible elastomeric material with at least limited permeability. The foam is resiliently deformable to resist sharp folding of the walls, and to resist relative in-plane motion of the walls.

Composite shell material for prosthesis

A method to make a silicone foam. A layer of crystalline material is embedded in a layer of uncured silicone. The crystalline material is closely packed in crystal-to-crystal contact, the crystals being provided in a plurality of sizes or ranges of size to increase the packing ratio of the crystals as a group. The silicone is cured and then the crystals are dissolved out with a solvent that dissolves them but does not dissolve the silicone.

Silicone foam and method for making it

A valve for an inflatable prosthesis of the type which comprises a fluid-containing envelope with an aperture closed by a valve through which a desired amount of fluid can be filled or withdrawn. The valve comprises a flat elongated conduit having a pair of sealed edges, and between said edges a pair of flat flexible wall members facing each other to form a fluid seal when they bear against one another. The conduit is open at one end. At the other end it is closed except for a slit formed in one of the walls without removal of material. The valve tends to remain closed both as a consequence of inherent closure of the slit and also as a consequence of pressure of the walls against one another.
