US Patent:

54288410, Jul 4, 1995

Filed:

Mar 9, 1994

Appl. No.:

8/208961

Inventors:

Daniel T. Stein - Newport Beach CA

International Classification:

A41D 1308
A41D 1900

US Classification:

2168

Abstract:

An improved surgical glove is provided having reinforcing pads formed over the distal finger and thumb pulps and over the metacarpal-phalangeal joints. The fingertips and thumb tips are the most likely region of a surgical glove to be accidentally penetrated by a needle during a surgical procedure. Furthermore, the fingertips, thumb tips, and metacarpal-phalangeal region of the surgical glove are the most likely portions of the glove to become abraded and possibly torn during a surgical procedure. Thus, the reinforcing pads are optimally located for minimizing the possibility of a tear or a needle penetration. The remaining portions of the surgical glove are of conventional thickness and flexibility, thereby assuring adequate mobility of the fingers and hand, such that precise surgical procedures may be performed while using the improved glove.

Daniel T. Stein - Newport Beach CA

International Classification:

A41D 1904

US Classification:

2169

Abstract:

An improved surgical glove is provided having reinforcing pads formed over the distal finger and thumb pulps and over the metacarpal-phalangeal joints. The fingertips and thumb tips are the most likely region of a surgical glove to be accidentally penetrated by a needle during a surgical procedure. The remaining portions of the surgical glove are of conventional thickness and flexibility, thereby assuring adequate mobility of the fingers and hand, such that precise surgical procedures may be performed while using the improved glove. A method for forming the glove and a glove mold are also disclosed. The glove is formed by dipping a glove mold in a liquid such as latex. The glove mold has recesses on volar sides of distal ends of the digits to retain a greater thickness of the liquid to form the reinforcing pads.

Appl. No.:

8/725394

Inventors:

Daniel Stein - Newport Beach CA

International Classification:

A61F 238

US Classification:

623 20

Abstract:

A prosthetic system comprising a patellar unit to replace the femoral surface of the patella with a convex prosthesis constructed from a low-friction material and an elongate femoral prosthesis for replacing the trochlear groove without use of bone cement. The femoral prosthesis has a arcuate indentation on its upper surface to accommodate the patellar prosthesis and a lower surface with diverging, protruding vanes. The lower surface and the vanes are made of a biocompatible material that promotes bonding to living bone. The femoral prosthesis is inserted by first driving a guide rod into the distal end of the femur. Then a guide frame is inserted onto the rod to guide an instrument in the cutting of a groove in the trochlear portion of the femur. Then a second guide frame replaces the first guide frame and acts as a template for cutting slots sized to receive the vanes of the prosthesis. Finally, the guide frame and rod are removed, and the prosthesis is slid into the cut groove with the vanes occupying the slots.

Abstract:

A prosthetic system comprising a patellar unit to replace the femoral surface of the patella with a convex prosthesis constructed from a low-friction material and an elongate femoral prosthesis for replacing the trochlear groove. The femoral prosthesis has a trough-like indentation on its upper surface to accommodate the patellar prosthesis and a lower surface with protruding vanes. The lower surface and the vanes are made of a biocompatible material that promotes bonding to living bone. The femoral prosthesis is inserted by first driving a guide rod into the distal end of the femur. Then a guide frame is inserted onto the rod to guide an instrument in the cutting of a groove in the trochlear portion of the femur. Then a second guide frame replaces the first guide frame acting as a template of cutting slots sized to receive the vanes of the prosthesis. Finally, the guide frame and rod are removed, and the prosthesis is pressed into the cut groove with the vanes occupying the slots.
