Patent number: 5514241Abstract: A puncture and cut resistant composite material comprising at least one elastomeric layer containing a plurality of flat platelets oriented substantially parallel to the plane of the elastomeric layer, wherein each of the platelets is a small, thin element substantially impervious to normally encountered puncturing and/or cutting by sharp objects, and wherein the platelets by their mutual overlap substantially cover any surface to which the composite material may be applied. This new composite material is particularly well-suited to the formation of gloves.Type: GrantFiled: February 27, 1995Date of Patent: May 7, 1996Inventors: Arnold S. Gould, Larry D. Nichols

Patent number: 4826481Abstract: An enteral feeding catheter is characterized by being adapted for introduction through the mouth via a guidewire that extends from the mouth through the esophagus, stomach and abdominal puncture. The catheter has a relatively stiff leading portion of length sufficient to extend along the guidewire from the mouth through the abdominal puncture and of stiffness sufficient to permit it to be pushed along the guidewire, at least an initial length of the catheter being tapered to a narrow leading tip to enable the puncture to be dilated as its drawn therethrough. The catheter also has a relatively soft, large diameter trailing portion connected to the leading portion adapted to be drawn along said guidewire by grasping and pulling the stiff leading portion until the leading end of the soft portion extends outside the body through the widened puncture, while the trailing end remains in the stomach, whereby the relatively soft trailing portion can serve as a conduit for enteric feeding.Type: GrantFiled: March 24, 1988Date of Patent: May 2, 1989Assignee: Abbott Labs.Inventors: Barry A. Sacks, Arnold S. Gould, Michael P. Manzo, Michael A. Ciannella

Patent number: 4624657Abstract: A medical device includes a flexible, elongated tube having a continuous, smooth, outer surface, adapted for introduction into the body, and a connection for introducing inflation fluid into the space defined by the length of the tube. The tube is elastomer and the tube wall is in a weakened state while adjacent portions of the tube are not so weakened, the wall of the selected portion having a lower resistance to expansion than adjacent portions. By use of heat-sensitive, annealable plastic, a tube of uniform thickness is weakened at a selected location by annealing. The selected limited-length portion, by reason of its weakened state, is adapted to preferentially respond to pressure of inflation fluid within the tube by expanding transversely to a balloon shape larger than adjacent portions of the tube that are subjected to the same pressure.Type: GrantFiled: November 15, 1983Date of Patent: November 25, 1986Assignee: Medi-Tech, IncorporatedInventors: Arnold S. Gould, Michael A. Ciannella

Patent number: 4552554Abstract: An introducing catheter for use in placing a large guidewire after a small guidewire is in position. The catheter has a tapered distal tip, decreased lumen size at the distal end, a side port and a ramp disposed within the tube at the distal end of the side port. The ramp is inclined distally toward the side port, the distal end of the ramp being fixed to the tube adjacent to the side port and the proximal end of the ramp being disposed adjacent the inner wall of the tube in the region opposite the side port in the manner that the small guidewire can move proximally past the ramp. The ramp deflects the distally moving larger wire so that it exists through the side port. In the embodiment shown, the ramp is formed integrally of low friction thermoplastic (PTFE) and the upper surface of the proximal end of the ramp has a convex, wire-deflecting contour as a result of thermoforming pressure.Type: GrantFiled: June 25, 1984Date of Patent: November 12, 1985Assignee: Medi-Tech IncorporatedInventors: Arnold S. Gould, Gary Sawicki, Michael A. Ciannella

Patent number: 4254575Abstract: A system of illuminating flying saucer-type toys for use at night or when visibility is poor by chemiluminescence. The invention includes a system for such illumination by the insertion of a hoop-shaped device to the underside of the toy. The hoop-shape is formed from a flexible rod-like device containing chemiluminescent materials.Type: GrantFiled: February 12, 1979Date of Patent: March 10, 1981Inventor: Arnold S. Gould

Patent number: 4138459Abstract: A process for the preparation of an open-celled microporous, polymer film. The improved process comprises the heat relaxing of a microporous polymer film which is formed from a non-porous, crystalline, elastic polymer film which has been uniaxially cold stretched at a temperature in the range of between about -20.degree. C. and a temperature 25.degree. C. below the crystalline melting temperature of the polymer film, followed by hot stretching, in the same direction, the cold-stretched film at a temperature in the range of between about 25.degree. C. below the crystalline melting temperature of the polymer film and 5.degree. C. below the crystalline melting temperature of the polymer film. The heat relaxing step comprises exposing the film under tension to a temperature in the range of between about 40.degree. C. below the crystalline melting temperature of the polymer film and 5.degree. C.Type: GrantFiled: September 8, 1975Date of Patent: February 6, 1979Assignee: Celanese CorporationInventors: Irving Brazinsky, William M. Cooper, Arnold S. Gould
