US Patent:

57122296, Jan 27, 1998

Filed:

Dec 9, 1996

Appl. No.:

8/762360

Inventors:

David P. Hopkins - Salt Lake City UT
Mohammad A. Khan - Sandy UT

Assignee:

Becton Dickinson and Company - Franklin Lakes NJ

International Classification:

C10M10750

US Classification:

508202

Abstract:

This invention relates to a new water soluble lubricant for a medical device, such as a catheter and an introducer needle. The lubricant is a silicone surfactant which is non-ionic and which is a good lubricating fluid. Preferably the silicone surfactant that is used is a block copolymer polyalkylene oxide-modified polydimethylsiloxane. Water is used as the solvent for this lubricant. The lubrication solution includes a solution stabilizer to clarify the solution and antimicrobial agents to inhibit microbial growth in the water solution or on the coated product. Vitamin E or its derivatives may also be used in the lubrication solution. When the lubrication solution is used to lubricate Teflon products, a small amount of a low molecular weight alcohol is added to the lubrication solution to increase wettability.

Assignee:

Becton Dickinson & Company - Franklin Lakes NJ

International Classification:

A61M 532

US Classification:

604265

Abstract:

This invention relates to the use of vitamin E or its derivative, such as vitamin E acetate, with a silicone lubricant for use on a medical device. The vitamin E prevents degradation of the silicone lubricant when the medical device is irradiated for sterilization.

International Classification:

C10M15502
C10M17302

US Classification:

508208

Abstract:

The two part tipping lubricant of this invention comprises water as the solvent. The lubricant is a silicone surfactant, which is non-ionic and which is a good lubricating fluid. No separate surfactant or lubricant is needed. The lubricant solution into which the catheter is dipped may also include low percentages of a solution stabilizer and an antimicrobial agent to clarify the solution and to inhibit microbial growth in the water solution. Vitamin E or its derivative may also be used in the lubrication solution to prevent degradation of the solution.

International Classification:

B29C 4302
B29C 4352
B29C 5700

US Classification:

264130

Abstract:

This invention relates to a process of making a shaped tip on a catheter. In this process, a lubricant solution is placed on a catheter, the catheter is placed on a mandrel, the catheter is heated, and the mandrel is engaged with a die to form a shaped tip on the catheter. The tipping lubricant of this invention comprises water as the solvent. The lubricant is a silicone surfactant, which is non-ionic and which is a good lubricating fluid. The lubricant solution into which the catheter is dipped includes low percentages of a solution stabilizer and an antimicrobial agent to clarify the solution and to inhibit microbial growth in the water solution. Vitamin E or its derivative may also be used in the lubrication solution.
