摘要： A surgical apparatus and methods for severing and welding tissue, in particular blood vessels, including an elongated shaft (36) having a pair of relatively movable jaws (40,42). at a distal end thereof . A first heating element (46) on one of the jaws heats up to a first temperature and form a welded region within the tissue, while a second heating element (48) on one of the jaws heats up to a second temperature and sever the tissue within the welded region. A control handle (38) includes controls for opening and closing the jaws, and may include an actuator for sending current through the first and second heating elements. A force -limiting mechanism (164) provided either within the control handle, in the elongated shaft, or at the jaws limits the pressure applied to the tissue by the jaws to ensure that the tissue is severed and the ends effectively welded within a short amount of time.

摘要： A surgical apparatus and methods for severing and welding tissue, in particular blood vessels, including an elongated shaft (36) having a pair of relatively movable jaws (40, 42) at a distal end thereof. A first heating element (46) on one of the jaws heats up to a first temperature and forms a welded region within the tissue, while a second heating element (48) on one of the jaws heats up to a second temperature and severs the tissue within the welded region. A control handle (38) includes controls for opening and closing the jaws, and may include an actuator for sending current through the first and second heating elements. The first and second heating elements may be electrically connected in series, and the first heating element may be bifurcated such that it conducts about one half of the current as the second heating element.

摘要： Assemblies and methods for carrying out a procedure on an organ or tissue in a closed or restricted space surgical site. A low profile head is configured and dimensioned to be delivered to a target location on the organ or tissue through an opening in a patient and having a contact surface configured to contact a surface of the organ or tissue at the target location. An elongated member extends proximally from the low profile head and has sufficient length so that a proximal end portion of the elongated member extends out of the opening in the patient when the contact surface of the head contacts the organ or tissue at the target location. The elongated member has a lumen extending longitudinally therethrough. An endoscope is dimensioned to be received in the lumen and has an elongated shaft of sufficient length such that when a distal tip of the endoscope extends into the head, and the contact surface contacts the organ or tissue at the target location, a proximal end portion of the elongated shaft of the endoscope extends out of the opening in the patient.

摘要： Devices and methods for performing an ablation procedure. One embodiment of a device includes a main body having proximal and distal end portions and first and second sides extending between the proximal and distal end portions. At least one ablation element is configured to apply an ablation energy or substance to tissue to be ablated. At least one electrode is movably positioned with respect to at least one of the sides of the main body, and each such electrode may be configured to assume a retracted position along that respective side of the main body, and an extended position extending beyond a perimeter of the main body. In one method embodiment, a method of performing ablation includes delivering an ablation energy or substance from an ablation device to a target area of tissue to form a lesion therein; delivering an electrical signal via said ablation device to non-ablated tissue on one side of the lesion; and monitoring non-ablated tissue on an opposite side of the lesion to assess whether electrical conduction through the lesion has occurred.

摘要： A surgical apparatus and methods for severing and welding tissue, in particular blood vessels, including an elongated shaft having a pair of relatively movable jaws at a distal end thereof. A first heating element on one of the jaws heats up to a first temperature and form a welded region within the tissue, while a second heating element on one of the jaws heats up to a second temperature and sever the tissue within the welded region. A control handle includes controls for opening and closing the jaws, and may include an actuator for sending current through the first and second heating elements. A force-limiting mechanism provided either within the control handle, in the elongated shaft, or at the jaws limits the pressure applied to the tissue by the jaws to ensure that the tissue is severed and the ends effectively welded within a short amount of time.
