Patent number: 6260699Abstract: Synthetic absorbable sutures are filled with a stabilizing agent, preferably a mixture of glycerol and calcium lactate, and inserted into a retainer having a narrow convoluted passageway. The retainer is inserted into an open foil pouch with a package stabilizing element such as a paper sheet filled with stabilizing agent. The package containing the suture, retainer and package stabilizing element is sterilized, aerated, equilibrated to a relatively high moisture level, and sealed. Long lengths of suture and doubled-over and tripled-over suture may be withdrawn from the retainer with low force without damaging the suture. Bends and kinks in the suture are prevented so as to provide a synthetic absorbable suture having highly desirable out of package hand and feel. The suture an removed from the package exhibits improved tissue drag characteristics.Type: GrantFiled: June 7, 1995Date of Patent: July 17, 2001Assignee: United States Surgical CorporationInventors: Donald S. Kaplan, Matthew E. Hermes, Ross R. Muth, David L. Brown, Henry A. Holzwarth

Patent number: 5674286Abstract: A completely bioabsorbable reinforced composite material for use in medical implants and a method for making same. The composite material comprises a hybrid yarn of intimately co-mingled reinforcement fibers of a crystalline polymer and matrix fibers of a polymer having a glass transition temperature below the melting point of the crystalline polymer. The hybrid yarn is heated under pressure to a processing temperature between the glass transition temperature of the matrix fibers and the melting point of the crystalline polymer to form a continuous matrix with reinforcing fibers of crystalline polymer. The composite material may be formed by a two step consolidation process.Type: GrantFiled: July 15, 1992Date of Patent: October 7, 1997Assignee: United States Surgical CorporationInventors: Keith D'Alessio, Donald S.

Patent number: 5518502Abstract: Methods for preventing and/or eliminating fogging of endoscope lenses during an endoscopic procedure which include the steps of introducing an endoscope into a body cavity and contacting the endoscope lens with a biocompatible and biodegradable composition containing a polyalkylene oxide while the lens is positioned within the body. Alternatively, the endoscope may be coated with a biocompatible polyHEMA coating which is activated by a biocompatible solution, such as water or saline, which may be introduced during use through a fluid conduit on the endoscope. Devices for preventing and/or eliminating fogging of endoscope lenses during endoscopic procedures and conveying antifogging solutions to the distal end of the endoscope are also provided, and may include a distensible applicator.Type: GrantFiled: June 8, 1994Date of Patent: May 21, 1996Assignee: The United States Surgical CorporationInventors: Donald S.
