Patent number: 7329233Abstract: An insufflation apparatus includes an elongated sleeve defining a longitudinal axis and having a proximal end and a distal end with a sharpened tip, an insufflation housing connected to the proximal end of the elongated sleeve and defining a port for receipt of insufflation gases, and a stylet disposed within the elongated sleeve and defining a passageway to direct the insufflation gases from the port into a body cavity. The stylet is movable between an extended position wherein the distal end of the stylet extends beyond the sharpened tip of the elongated sleeve and a retracted position wherein the distal end of the stylet is proximal of the sharpened tip of the elongated sleeve. A biasing member may be engagable with the stylet so as to bias the stylet toward the extended position. Preferably, the housing has a translucent wall and the stylet is dimensioned so that the proximal end of the stylet is visible through the translucent wall when the stylet is in the retracted position.Type: GrantFiled: October 5, 2004Date of Patent: February 12, 2008Assignee: Tyco Healthcare Group LPInventor: Richard D. Gresham

Patent number: 7294116Abstract: Smoke evacuation apparatus designed to provide safe and efficient filtration and evacuation of smoke plume generated by laser-surgical, electrosurgical, radiosurgical, and electrocautery devices. A filter assembly is removably mounted on a front panel of the apparatus housing and is thus easily accessible from the front side which typically faces the user. The filter assembly at its front is provided with a hose connector to which the suction hose of the system is conveniently attached, and the front of the filter assembly is configured with a symbol, such as a letter or number, that represents an identification of the system supplier or manufacturer, and the hose connector is mounted on that symbol identifier.Type: GrantFiled: January 3, 2005Date of Patent: November 13, 2007Inventors: Alan G. Ellman, Jon C. Garito

Patent number: 7250035Abstract: A method and apparatus for treating gas for delivery into a body cavity, body space or body surface of an animal. The apparatus comprises a housing defining a chamber having an entry port and an exit port. One or more agents are released into the gas stream that flows through the chamber so that the gas stream carries the agent to the animal.Type: GrantFiled: July 27, 1999Date of Patent: July 31, 2007Assignee: Lexion Medical, LLCInventors: Douglas E. Ott, John F. Schaefer, Robert I. Gray

Patent number: 7147813Abstract: A method of addressing a condition of a living body comprising the steps of using an energy beam to form a set of pores in a work piece biocompatible membrane. The pores should have a mean area of less than 500 ?m through the biocompatible membrane, thereby producing a microporous membrane adapted to facilitate tissue in growth. This membrane is placed at least partially about an article that is adapted to be implanted in a living body, which is implanted into the living body, thereby addressing the condition.Type: GrantFiled: April 4, 2005Date of Patent: December 12, 2006Assignee: Isense CorporationInventors: Kenneth Ward, Jerome J. Boogaard

Patent number: 7070586Abstract: A trocar system for providing access across a body wall includes a trocar and an anchor provided in the form of a first helix. The anchor is adapted for placement in an operative position wherein the anchor extends at least partially through the body wall. A second helix formed on the trocar is size and configured to engage the first helix of the anchor so that rotation of the trocar relative to the anchor moves the second helix along the first helix. In this manner, the trocar is drawn into the anchor as it moves into the body wall. A proximal force applied to the anchor resists tenting of the abdominal wall. The anchor also holds the layers of the body wall together thereby resisting peritoneal separation.Type: GrantFiled: March 3, 2003Date of Patent: July 4, 2006Assignee: Applied Medical Resources CorporationInventors: Charles C. Hart, John R. Brustad
