Patent number: 6685727Abstract: Openings in a mammalian body made by any medical procedure or non-medical event are sealed with a bioabsorbable plug or sewn with a bioabsorbable suture. In one exemplary embodiment, the plug in dehydrated, unexpanded condition is pushed by a pushing device through the lumen of a needle until a first part of the plug is external to the opening and a second part is internal to the opening. The needle is then withdrawn while the position of the pushing device is maintained. The pushing device is then withdrawn, leaving the plug in sealing relation to the opening. The body's moisture causes the plug to expand to complete the sealing of the opening, or the expansion may be caused by exposure to air, light, or other stimulant. The opening may be formed in soft tissue, internal organs, or hard tissue. The plug seals the flow of liquid or gaseous biological fluids.Type: GrantFiled: March 27, 2003Date of Patent: February 3, 2004Assignee: Bio-SEAL, LLCInventors: John S.

Patent number: 6482179Abstract: Medical devices, and more particularly, devices, methods and compositions for sealing tissue puncture openings of patients after surgical operations are provided. A puncture wound sealing apparatus includes a positioning device having a depth sensing mechanism capable of providing feedback to an operator for the precise placement of an implant that is preferably resorbable and swellable after implantation. Such an implant provides for efficient sealing of the tissue puncture opening thus avoiding complications after surgical procedures in which blood vessels are punctured.Type: GrantFiled: May 24, 2000Date of Patent: November 19, 2002Assignee: Cohesion Technologies, Inc.Inventors: George H.

Patent number: 6479725Abstract: A method for forming an incision or wound dressing. First, second, and third layers 2-octyl cyanoacrylate adhesive 18, 20, and 22 are applied to a wound or incision site 14, with each layer covering the site 14 and extending to at least about five millimeters from each side of the site 14. After the first, second, and third layers 18, 20, and 22 are allowed to polymerize, a fourth layer 24 of 2-octyl cyanoacrylate adhesive is applied, the fourth layer 24 substantially covering at least one millimeter of the extending edge of the first, second, and third layers 18, 20, and 22. In the case of a high-tension wound or a wound near a joint, the fourth layer 24 extends at least about ten millimeters from each side of the site 14, and a fifth layer 26 of 2-octyl cyanoacrylate adhesive is applied.Type: GrantFiled: June 30, 2000Date of Patent: November 12, 2002Inventor: Lisa M. Brothers
