Patent number: 6866656Abstract: A lubrication system is disclosed which minimizes friction and that is useful for application on the surface of a flexible portion of a medical device. Such a lubrication system includes a lubricant that is able to move when the flexible portion of the medical device flexes and is biocompatible and is not degraded by the application of alcohol or other conventional medical sterilizing and cleaning agents. The lubricant is bonded to the surface of the flexible portion of the medical device. The lubrication system may be used on an elastomeric septum, such as a silicone rubber elastomer. The lubricant coating may be any type of coating that can be chemically bonded to the elastomer, such as di-paraxylene, poly-(p-xylene), polytetrafluoroethylene, or polyvinylpyrrolidone.Type: GrantFiled: January 24, 2002Date of Patent: March 15, 2005Assignee: Becton, Dickinson and CompanyInventors: Kevin Tingey, Steven W. Johnson, E. Robert Purdy, Douglas P. Orr, Min-Shiu Lee

Patent number: 5863614Abstract: An apparatus for applying a coating to an object includes a pair of reciprocating members which each include a porous resilient pad mounted for movement toward and away from each other. The apparatus includes a coating supply system for supplying coating to the resilient pads. The pads have a movement sequence from an initial rest position where the pads are spaced apart from one another to a coating loading position where the pads are in physical contact and have a degree of compression with each other to load the coating onto the pads, then the pads are moved to an intermediate rest position with the pads spaced apart an the object to be coated is moved between the pads. The sequence then includes a coating delivery position where the pads are in physical contact with each other and the object so that the pads have a degree of compression with each other and the object thereby applying the coating to the object.Type: GrantFiled: May 28, 1997Date of Patent: January 26, 1999Assignee: Becton Dickinson and CompanyInventors: Victor A. Williamitis, Jeanne E. Lambert, Min Shiu Lee, Robert A. Taller

Patent number: 5773081Abstract: An apparatus for applying a coating to an object includes a pair of rotating members each including a porous resilient roll mounted for counter-rotatory movement. The members are mounted so that they contact each other during a segment of the movement and are out of contact with each other at other segments of the movement. The apparatus includes a coating supply system for supplying a coating to the resilient rolls. The rotatory movement of the members includes a coating loading segment where the resilient rolls are in physical contact and have a degree of compression with the coating supply system for loading the coating into the rolls. The sequential movement also includes an intermediate segment where the resilient rolls are out of contact with each other and where an object to be coated is movable into position for movement between the resilient rolls when the rolls are in a coating delivery segment.Type: GrantFiled: July 31, 1997Date of Patent: June 30, 1998Assignee: Becton Dickinson and CompanyInventors: Victor A.

Patent number: 5453099Abstract: A catheter tubing has a layer of a hydrophobic stiffening polymer encapsulated by a layer of hydrophilic thermoplastic base polymer. Preferred stiffening polymers are polyesterpolyether block copolymers. Preferred base polymers are thermoplastic polyetherurethanes. The encapsulated layer may be a stripe or an annular layer having base polymer layers laminated on both surfaces thereof.Type: GrantFiled: May 18, 1994Date of Patent: September 26, 1995Assignee: Becton, Dickinson and CompanyInventors: Min-Shiu Lee, Mutlu Karakelle, David E. Spielvogel, Robert A. Taller

Patent number: 5302392Abstract: A polyurethane composition has particles of solid polyvinylpyrrolidone-iodine complex evenly distributed throughout the polyurethane matrix so that the complex does not associate with the polyurethane to any appreciable extent. In one embodiment of the composition, the polyurethane is thermoplastic for coating or molding applications. In another embodiment, the composition is a polyurethane foam particularly useful as a sponge for scrubbing which provides almost instantaneous release of the complex. The sponge may be provided in a package which includes other items useful for scrubbing.Type: GrantFiled: August 20, 1990Date of Patent: April 12, 1994Assignee: Becton, Dickinson and CompanyInventors: Mutlu Karakelle, C. David Benson, Robert A. Taller, Min-Shiu Lee, Mohammad A. Khan

Patent number: 5302385Abstract: A copolymer having free hydroxyl groups is formed from N-vinyl pyrrolidone and allyl alcohol. A polyurethane is formed from a reaction mixture which includes the copolymer, a diisocyanate, a chain extender and a polyglycol. The polyurethane takes up iodine to give a complex useful as an antimicrobial coating on a medical article or as an antimicrobial foam sponge or wound dressing.Type: GrantFiled: August 20, 1990Date of Patent: April 12, 1994Assignee: Becton, Dickinson and CompanyInventors: Mohammad A.
