Patent number: 8758363Abstract: An endoscopic needle device comprises a handle and a catheter sheath connected to the handle, wherein the catheter sheath has at least one lumen, for example a needle lumen and a stabilization lumen, extending therethrough. A needle is selectively movable within the needle lumen between a needle retracted position and a needle extended position and a stabilization element is selectively movable within the stabilization lumen between a stabilizer retracted position and a stabilizer extended position. A linking mechanism may operatively connect the needle and the stabilization element so that when the needle is in the needle retracted position the stabilization element is in the stabilizer extended position and when the needle is in the needle extended position the stabilization element is in the stabilizer retracted position.Type: GrantFiled: April 26, 2012Date of Patent: June 24, 2014Assignee: Boston Scientific Scimed, Inc.Inventors: Srinivas Nishtala, Tim E.

Patent number: 7981052Abstract: An embodiment of the invention includes a device for collecting body tissue. The device may include an inner member comprising a hollow portion to collect body tissue and a distal end configured to both penetrate body tissue and define an opening of the hollow portion. The device may further include an outer member, co-axially and slidably disposed around the exterior of the inner member, comprising a distal end portion. The distal end portion of the outer member may be configured to penetrate body tissue, prevent body tissue from exiting the hollow portion of the inner member, and allow the distal end of the inner member to extend beyond the distal end of outer member. The opening of the hollow portion of the inner member may be disposed in a plane that is not perpendicular to the longitudinal axis of the inner member.Type: GrantFiled: October 10, 2006Date of Patent: July 19, 2011Assignee: Boston Scientific Scimed, Inc.Inventors: Srinivas Nishtalas, Tim E.

Patent number: 7959610Abstract: An apparatus and method for insertion of medical devices is disclosed. One embodiment includes an access tube with a retention portion disposed at a distal end. The retention portion is reconfigurable between first and second configurations of reduced and increased lateral extent. A trocar can be movably disposed within the access tube, which can be movably disposed within an overtube. One method of the invention includes inserting the trocar and access tube through a patient's body wall where the retention portion is configured from a reduced to an increased lateral extent. An overtube can be inserted around the access tube through the body wall where the retention portion can be received through a slot defined by the overtube. The retention portion can be returned to reduced lateral extent. The access tube can be removed and the medical device can be inserted within the overtube.Type: GrantFiled: February 5, 2007Date of Patent: June 14, 2011Assignee: Boston Scientific Scimed, Inc.Inventors: Linda D.
