Abstract: Methods are provided for partial aortic obstruction for cerebral perfusion augmentation in patients suffering from global or focal cerebral ischemia. Alternatively, the methods can be used to partially obstruct aortic blood flow to condition the spinal cord to secrete neuroprotective agents prior to abdominal aortic aneurysm repair. Partial obstruction of a vessel can be accomplished by a device comprising an elongate catheter and a distally mounted expandable member. The expandable member may comprise one or two balloons. Other medical devices, such as an angioplasty, stent, or atherectomy catheter, can be inserted distal the expandable member to provide therapeutic intervention.

Abstract: A suture lock including a first bore, a first restriction member extending into the first bore for restricting the movement of a suture element within the first bore, an optional second bore, and a second restriction member extending into the second bore for restricting the movement of a suture element. The suture lock may be provided in a system including a suture element. Methods of using the suture locks are also described.

Abstract: Methods are provided for cerebral perfusion augmentation in patients suffering from global or focal cerebral ischemia. Methods include partial or complete obstruction of the femoral or iliac arteries or the inferior vena cava, external compression of the iliac, femoral, or brachial arteries, placing the patient in a trendelenberg position, applying one or more compression members to the extremities, or removing portion(s) of cerebral spinal fluid. Partial obstruction of a vessel can be accomplished by a device comprising an elongate catheter and a distally mounted expandable member. The expandable member may comprise one or two balloons. Other medical devices, such as an angioplasty, stent, or atherectomy catheter, can be inserted distal the expandable member to provide additional therapeutic intervention.

Abstract: A stent having a stent body and a embolic body is disclosed. The stent body is collapsible for insertion into a vessel or other lumen within a patient and is radially expanded at the site of an aneurysm so that the embolic body is received within the aneurysm to support and/or promote clotting within the aneurysm. The embolic body may also be collapsible and radially expandable.

Abstract: An instrument for performing a percutaneous laparoscopic cholecystectomy includes a generally rigid, tubular body with a proximal end, a distal end and a lumen extending between these two ends and with a pair of bipolar electrodes projecting from the distal end of the tubular body and a handle member affixed to its proximal end. The outside diameter of the tubular body is sufficiently small that it can readily pass through a cannula inserted through a puncture made through the abdominal wall. A pair of conductors, connected at one end to the bipolar electrodes and at their other end to a source of radio frequency voltage, extend through the tube's lumen and a handle. Moreover, a fluid port may be formed through the handle so as to be in fluid communication with the lumen of the tube whereby fluids may be perfused through the instrument during its use or a suction may be applied to the proximal port for aspirating the surgical site.

Abstract: An bipolar electrosurgical instrument especially designed especially for use in freeing and rerouting of the internal mammary artery during coronary bypass surgery. It comprises a rigid pen-like handle having appropriate cut and coag control switches mounted thereon and a bendable tubular extension projecting from the distal end of the handle member. Mounted on the distal end of the extension is a blade holder designed to contain an ultrasonic transducer as well as the proximal end of the blade itself. The blade comprises a ceramic substrate having a pattern of metallization thereon defining a bipolar cutting gap along the side and end edges of the blade and a bipolar coagulating gap located inwardly from the side and end edges. A cable is used to join the implement to an electrosurgical generator and the individual wires in the cable extend through the pen-like body, the tubular extension and into the blade holder where electrical connections are made to the electrodes on the blade itself.
