Heat Shrinkable Film Patents (Class 128/DIG18)
  • Patent number: 5315747
    Abstract: This invention relates to the preparation of a balloon dilatation catheter which comprises blowing a length of double lumen tubing to produce a double lumen catheter piece having distal and proximal ends and having a first lumen and a second lumen; cutting an opening in the second lumen proximal to the distal end of the catheter piece; inserting a pushing wire having distal and proximal ends into the second lumen through the proximal end of the catheter piece until the distal end of the pushing wire extends distally across the opening; inserting a piece of lubricous tubing into the second lumen through the distal end of the catheter piece; sealing the distal end of the first lumen; heating the distal portion of the catheter piece to cause the distal portion of the second lumen to shrink slightly to cause the lubricous tubing to fixedly engage the distal end of the pushing wire, while the first lumen is pressurized; and heating the remainder of the catheter piece to cause the second lumen to shrink around the

  • Patent number: 4752288
    Abstract: A one-piece sealed disposable enema unit with a lubricated rectal tip is disclosed. The rectal tip of the unit is sealed with a break-off tab. Attached to the tab is a sleeve which covers the exterior of the rectal tip and prevents contamination of the lubricant. Before use, the break-off tab must be twisted off and the tab with the attached sleeve removed. Therefore, the unit is tamper proof and security of the contents is insured.

  • Patent number: 4645491
    Abstract: The invention provides a catheter placement apparatus for use in inserting a catheter to a preferred depth, the device comprising a surgical needle with a longitudinal window through which a catheter inserted into the needle can be viewed, and a catheter having a colored patch of the same length as the window and a series of spaced, visually distinct markings, proximal to the patch. The position of the catheter can be accurately located by aligning the colored patch with the window and then inserting the catheter until at least one mark appears in the window, recording the distance of a mark from the surface of the skin and using this recorded distance to relocate the catheter, if necessary.

  • Patent number: 4475903
    Abstract: The invention relates to a disposable syringe comprising a barrel which has on its front end a needle connection with injection needle and needle guard. The syringe is provided with a sealing member for the needle guard which consists of a sleeve of shrinkable plastic material. The sleeve is shrunk on one side around the needle connection and/or around the barrel or a front part of the barrel, and on the other side around a part of the needle guard adjoining the needle connection.

  • Patent number: 4323071
    Abstract: A combination guiding catheter assembly and a dilating catheter assembly. The guiding catheter assembly includes a first flexible tubular member formed of a material which has a low coefficient of friction and a second flexible tubular member encasing said first tubular member so that the first tubular member fits tightly in the second tubular member. The combined first and second tubular members have proximal and distal ends with a fitting mounted on the proximal end. The dilating catheter assembly includes a flexible tubular member. The tubular member of the dilating catheter assembly having proximal and distal ends and an inflatable annular portion formed integral with the tubular member of the dilating catheter assembly near the distal end thereof. A fitting is mounted on the proximal end of the tubular member of the dilating catheter assembly. The dilating catheter assembly is disposed within the guiding catheter assembly.
