Patent number: 5067965Abstract: An improved bio-osmotic gel for filling implant lumens consisting substantially of an amount of a bio-compatible organic polymer and a solution of bio-compatible salt is disclosed which exhibits osmotic qualitites closely paralleling that of human body serum and improved radiolucency with respect to silicone oil and saline. The bio-osmotic gel can contain a polymer having the empirical formula [(CHCH.sub.2).sub.2 N(CH.sub.2).sub.3 CO].sub.n i.e. polyvinylpyrrollidone. The bio-compatible salt can be made of a low Z value salt such as sodium bicarbonate, sodium acetate, or sodium lactate. The gel material should have an osmolarity between 250 and 350 milliosmoles and have an X-ray absorption under standard exposure approximately equal to that of breast tissue such that processed mammographic X-ray film will have an optical density of 1.2 to 1.3 and an average penetrance of between 9.2 and 30.0 milliroentgens.Type: GrantFiled: March 20, 1990Date of Patent: November 26, 1991Assignee: Bioplasty, Inc.Inventors: Robert A.

Patent number: 5045075Abstract: A surgical drain system includes an elongated drain member having a conduit portion connected to a fluid intake portion with a fluid flow passage extending continuously through both portions and with at least one fluid intake opening in the fluid intake portion. The conduit portion of the drain member has generally a marquise-shaped transverse cross-section, whereas the fluid intake portion has a similar cross-sectional shape but absent the pointed end portions of the marquise shape. In use, the drain member may be positioned with the fluid intake portion within the wound in a desired position and with the conduit portion traversing the wound, and the wound edges may easily be made to conform to the marquise shape of the conduit portion to form a substantial seal. The drain member also preferably includes a one-way valve connected to the conduit portion for preventing fluid from flowing into the wound through the drain member.Type: GrantFiled: June 23, 1989Date of Patent: September 3, 1991Assignee: Renoble, N.

Patent number: 4955909Abstract: Capsular contracture causing firmness of soft silicone implants is a serious problem that may result from several causative factors that have as their final pathway, the development of increased scar tissue. The present invention has altered the formation of this scar encapsulation of silicone implants by texturing the silicone surface in order to gain fibroblast ingrowth into the interstices and thus prevent micromotion at the host prosthesis interface. It has been found that this produces a thinner fibrous capsule. Previously published work pertaining to animals and man has shown that similar texturing of tetrafluoroethylene (Teflon) and other substances achieves these goals. In accordance with work leading up to the present invention, textured silicone samples have been implanted in the subcutaneous layer of rabbits, the capsule formation and the host-prosthesis interface studied histologically.Type: GrantFiled: January 31, 1989Date of Patent: September 11, 1990Assignee: Bioplasty, Inc.Inventors: Robert A.
