US Patent:

8501645, Aug 6, 2013

Filed:

Jun 30, 2005

Appl. No.:

11/171900

Inventors:

Van Hai Pham - Irvine CA, US

International Classification:

D02G 3/22

US Classification:

442339, 4283044, 428376, 428397

Abstract:

Filamentous bodies which are longitudinally extended and other film-like constructions are made by combining liquid silicone-containing precursors with air and extruding them. Distinct types or grades of fibers, strands, and other film-like constructions are produced which have a multiplicity of useful applications and indications for use owing to their inherent memory, compactability, tensile strength and density. Processes for making the novel enhanced filamentous bodies and products by the same can be optimized for uses ranging from safe and effective (“leak-free”) prosthetics to cushions, inserts, membranes, in a plurality of fields from consumer electronics to medical devices, and athletic or orthopedic shoe inserts.

Appl. No.:

7/600265

Inventors:

Van H. Pham - Irvine CA

International Classification:

A61F 218

US Classification:

623 10

Abstract:

The nasal implant of this invention is characterized by a composition of hard-grade silicone fashioned into a special shape. One variation in the composition material is to use soft silicone only for the tip in order to overcome the fear of some surgeons to use hard silicone in this particular area. A special and improved shape of the implant, in the form of a modified hourglass, provides a well rounded and larger tip portion thanb that of the prior art. The supra-tip of this improved implant shows a depression dorsally, is less wide than the rest of the implant and has a pronounced slope laterally. These features, particularly at the supra-tip region avoid the unnatural effects of the prior art devices. Moreover this implant has a variable thickness form upper end to tip -that is it starts thin, increases in thickness and then goes thinner again- whereas the prior art starts thin and continually increases throughout.

International Classification:

US Classification:

450 57, 623 7, 524588

Abstract:

Filamentous bodies which are longitudinally extended and other film-like constructions are made by combining liquid siliceous precursors with air and extruding them. Distinct types or grades of fibers, strands, and other film-like constructions are produced which have a multiplicity of useful applications and indications for use owing to their inherent memory, compactability, tensile strength and density. A prosthetic device for a mastectomy bra is constructed with filamentous bodies. It can be sewn permanently into the bra cup. The device can be refilled to counteract volume loss.
