Patent number: 7824420Abstract: An implantable prosthesis for an anatomical defect, such as a tissue or muscle defect, that promotes tissue or muscle growth into the prosthesis and subsequently strengthens the area of the defect. At least one pocket and preferably two concentric pockets may be provided to aid with manipulating the prosthesis. Where two pockets are used, a barrier or partition exists between the pockets and the outer pocket allows manipulation of the outer periphery. The incidence of postoperative adhesions between a portion of the prosthesis and tissue, muscle or organs may be minimized with the use of a barrier layer. Reinforcing members may be attached to portions of the prosthesis to aid in positioning and deployment in the area of desired coverage without rendering the prosthesis unduly difficult to implant or uncomfortable for the patient. Typically, two concentric members are employed.Type: GrantFiled: May 26, 2004Date of Patent: November 2, 2010Assignee: C.R. Bard, Inc.Inventors: Stephen N. Eldridge, Roger Darois

Publication number: 20080269896Abstract: An implantable prosthesis and a method of repairing an anatomical defect, such as a tissue or muscle wall defect, by promoting tissue growth thereto, while limiting the incidence of postoperative adhesions between a portion of the prosthesis and tissue or organs. The prosthesis is formed of a biologically compatible, flexible layer of repair fabric suitable for reinforcing tissue or muscle and closing anatomical defects, and a barrier layer for physically isolating at least a portion of one side of the fabric from areas likely to form adhesions. A peripheral barrier extends about at least a portion of the outer peripheral edge of the repair fabric to inhibit adhesions between the outer peripheral edge and adjacent tissue and organs. The repair fabric may include an outer margin that has been melted and resolidified to render the outer peripheral edge substantially impervious to tissue ingrowth.Type: ApplicationFiled: July 10, 2008Publication date: October 30, 2008Applicant: C.R. Bard, Inc.Inventors: Dennis Cherok, Roger Darois, Ronald L. Greene, Thomas J. Capuzziello, James D. Mello

Publication number: 20070250064Abstract: A surgical fastener system includes a plurality of fasteners having a throughbore with an internally threaded portion. The fasteners may engage with a threaded mandrel that passes through the throughbore of the fasteners. A rotator may rotate the fasteners relative to the mandrel to move at least one of the fasteners along the mandrel, e.g., along the mandrel's longitudinal axis. A distal end of the mandrel may be inserted into a material, such as a tissue, prosthetic or other, and a fastener may be deployed from the distal end of the mandrel while the distal end is positioned in the material. The throughbore of the fasteners may include a threaded portion and an unthreaded portion, may include an angled face or other feature to aid in fastener deployment and/or have curved depressions in the head portion.Type: ApplicationFiled: April 21, 2006Publication date: October 25, 2007Applicant: Davol, Inc.Inventors: Roger Darois, Gus Felix, Alan Bachman, Ray Adams, Joe Paul, Ed Chester, Adam Lehman, Barry Smith, Jeffrey Stein

Publication number: 20060064175Abstract: An implantable prosthesis for repairing or augmenting anatomical defects, including an inguinal hernia. The prosthesis includes a repair fabric having a body portion and a support member that may be arranged in or on the repair fabric to help deploy the repair fabric at the surgical site and/or help inhibit folding or buckling of the repair fabric. The support member may substantially surround the body portion to help deploy and/or hold the body portion in a spread out configuration for covering the defect. The support member may include first and second ends that are spaced apart to form an interruption so that a slit or keyhole arrangement may be formed in the repair fabric through the interruption and into an interior region of the body portion to receive a body structure, including a cord structure such as the spermatic cord.Type: ApplicationFiled: September 20, 2004Publication date: March 23, 2006Inventors: Edouard Pelissier, Valerie Vadurro, Stephen Clarke, Roger Darois, David Hass

Publication number: 20050027369Abstract: An implantable prosthesis is provided for repairing or augmenting anatomical weaknesses or defects, and is particularly suitable for the repair of soft tissue and muscle wall openings. The prosthesis may include a repair fabric that is constructed and arranged to allow tissue ingrowth and is susceptible to erosion into and the formation of adhesions with tissue and organs. One or more regions of the prosthesis may be configured to inhibit erosion into and/or the formation of adhesions with tissue and organs. The prosthesis may include an erosion resistant edge to buffer an edge of the fabric from the adjacent tissue or organs. The erosion resistant edge may be provided along an opening that is adapted to receive a tube-like structure, such as the esophagus.Type: ApplicationFiled: September 2, 2004Publication date: February 3, 2005Inventors: Stephen Eldridge, Roger Darois, Michael Lee, Valerie Vadurro

Patent number: 6613035Abstract: An autotransfusion system for collecting blood from a patient and reinfusing the blood back into the patient is disclosed. The system includes a collection unit, a manually operable portable suction evacuator removably connected to the collection unit, and a blood reinfusion bag removably connected to the collection unit. The collection unit includes a collection chamber that is oversized relative to the volume of blood that the unit is intended to contain, and an airflow port located and oriented in the collection chamber to prevent blood from leaking into the port when the collection unit is oriented upright or on its side. When connected to the patient, the collection unit and portable suction evacuator are maintained free of blood by enclosing them within a substantially transparent, flexible envelope. The envelope enables the unit and evacuator to be connected and set-up for proper operation while preventing blood from contacting the outer surfaces of the unit and evacuator.Type: GrantFiled: November 13, 1998Date of Patent: September 2, 2003Assignee: C. R. Bard, Inc.Inventors: Richard Longo, John Uhoch, Dennis Cherok, Roger Darois, Robert Sakal

Patent number: 6485452Abstract: A medical suction and irrigation apparatus includes a suction/irrigation tip removably connected to a conventional suction/irrigation handpiece. Suction is provided through a suction tube which has a bypass conduit in the tip. The bypass conduit is directly connectable to a suction source so that aspirated debris passes through the tip to the suction source. The suction tube thus prevents aspirated debris from entering the conventional suction tube in the handpiece and contaminating the handpiece. The suction tube is also designed to have a maximum size to prevent the tip from clogging. The tip also has an irrigation tube for directing irrigation liquid to the irrigation site, and a connector which connects the irrigation tube to the handpiece so that the handpiece pumps fluid through the tip in a conventional manner. A flexible splash shield, slidably mounted to the irrigation tube, confines irrigation fluid to the local site.Type: GrantFiled: November 2, 2000Date of Patent: November 26, 2002Assignee: C. R. Bard, Inc.Inventors: Glen French, Stephen Albrecht, Roger Darois, Robert Sakal, Laurence Tremaine

Patent number: 5792098Abstract: An apparatus for irrigating a local irrigation site includes a suction/irrigation tip that is removably connected to a suction/irrigation handpiece. The tip includes a connector to detachably connect the tip to the handpiece, a suction tube detachably connected to the connector, and an irrigation tube permanently fastened to the connector. The tip may also have a securing clip to prevent the irrigation tube from bending during use, and a retaining finger to partially connect the tip to the handpiece.Type: GrantFiled: June 19, 1996Date of Patent: August 11, 1998Assignee: C.
