Patent number: 6638273Abstract: A catheter having expandable electrodes for applying energy to a hollow anatomical structure such as a vein. When used on a vein, the catheter is useful for a minimally invasive treatment of venous insufficiency. The catheter includes conductive end rings to which the electrodes are attached, for mechanically connecting and electrically tying electrodes together to provide for a single wire electrical connection points, for transmitting energy while more evenly spacing the electrodes. Expandable arms are formed of electrically conductive material and insulated along their length except for an intermediate section that functions as the electrode. The arms are tapered to allow more room for wiring and to reduce the possibility of shorting between the ends of the arms. The catheter further includes thermocouples in the electrodes for measuring temperatures on the outer surface of the electrode. Slots are formed in the arms for mounting the thermocouples.Type: GrantFiled: November 27, 2000Date of Patent: October 28, 2003Assignee: VNUS Medical Technologies, Inc.Inventors: Brian E.

Patent number: 6475139Abstract: Described is a surgical instrument and method for treating female urinary stress incontinence. The instrument includes a curved needle-like element defining in part a curved shaft having a distal end and a proximal end. A tape attaches to the needle for implanting into the lower abdomen of a female to provide support to the urethra. The needle defines an inner lumen for passage of optical devices and/or fluids. A surgical optical system may interface directly with the needle, or alternatively, the needle hand piece or handle may be modified to accept the optical system. The tip of the needle is also modified to contain a window or viewing port that allows for the transmission of light from the ambient target tissue into the imaging lens of the optical system. The optical system allows the surgeon to maintain continuous anatomic visualization during introduction and navigation of the needle within the lower abdomen.Type: GrantFiled: May 18, 2000Date of Patent: November 5, 2002Assignee: Ethicon, Inc.Inventor: Gary H.

Publication number: 20020123665Abstract: A medical scope adapted for use in viewing an image of an interior section of a body includes a housing having a viewing mechanism for viewing the image. An elongated shaft extends from the housing and includes a sheath and an image transmitting mechanism extending through the sheath for optically transmitting the image from the interior section to the viewing mechanism. The sheath is made from a superelastic material such that the sheath has an elasticity greater than that of the image transmitting mechanism, whereby the bending of the shaft and hence the image transmitting mechanism is restricted primarily by the elastic limit of the image transmitting mechanism and not by the elastic limit of the sheath. The medical scope of the present invention can be any type of medical scopes, including rigid, semi-flexible and flexible endoscopes, medical telescopes, hysteroscopes, bronchialscopes and cystoscopes.Type: ApplicationFiled: December 29, 2000Publication date: September 5, 2002Applicant: Ethicon, Inc.Inventor: Gary H.

Patent number: 6149660Abstract: A delivery device and method for intraluminally deploying a clip appliance within a body lumen or cavity of a patient, for example a vein. The clip is configured from a wire-like, bendable material, having a "W"-like sinusoidal shape. The clip is constructed with sharpened slanted edges at the tips which provide preferential bending and straightening when the clip is deployed into patient tissue, for example, a venous valve. The delivery device comprises a catheter and a structure for bending and releasing the clip. The catheter is configured with an elongate flexible tubular member secured to a slotted housing having a distal tapered tip. A handle is secured to the proximal end of the flexible tubular member. A balloon and actuator arm combination is disclosed for forcing a clip against an anvil to bend the clip from an open to a closed condition and for releasing the clip from a slot in a side wall of the housing. The housing may be configured to retain and deploy a plurality of clip appliances.Type: GrantFiled: April 22, 1996Date of Patent: November 21, 2000Assignee: VNUS Medical Technologies, Inc.Inventors: Michael D.

Patent number: 6086584Abstract: The invention provides exemplary electrosurgical probes and methods for their use. In one exemplary embodiment, an electrosurgical probe comprises a probe body having a proximal end, a distal end and at least one lumen. An electrode assembly is operably coupled to the distal end. The electrode assembly includes an electrode and a jacket disposed to cover at least a portion of the electrode. The jacket and the electrode have a combined mass sufficient to dissipate heat during operation of the electrode so that the electrode does not experience material degradation. Further, the jacket provides insulation between the electrode and a conductive medium such that the electrode is operable in the conductive medium.Type: GrantFiled: September 10, 1998Date of Patent: July 11, 2000Assignee: Ethicon, Inc.Inventor: Gary H.

Patent number: 5730136Abstract: A test system and method for evaluating the efficiency of the venous pump in leg muscles and for identifying incompetent venous valves. The test system comprises a legging having inflatable bladders, a manifold and a system controller. A pressurized inflation source is provided which is in fluid communication with the manifold and the legging. The controller sequences valves within the manifold to inflate and deflate the bladders of the legging. The test system further includes a Doppler blood flow sensor interfaced to the controller. The sensor is configured with a housing which contains a rotatable disk, upon which two pairs of crystals are disposed. The sensor housing is secured a leg of a patient proximate a blood vessel in which blood flow is to be measured. The patient is positioned on a reclinable test station, upon which the controller and manifold may be mounted.Type: GrantFiled: October 16, 1996Date of Patent: March 24, 1998Assignee: VNUS Medical Technologies, Inc.Inventors: Michael D.

Patent number: 5263931Abstract: A catheter system for dilating the prostatic urethra of a male patient. The catheter has an elongated tubular catheter body with an inner lumen extending therein, an inflatable relatively inelastic balloon on the distal extremity of the catheter body, a core member extending through the balloon interior and at least to and preferably out the distal end of the catheter body where a flexible body such as a helical coil is disposed about and secured thereto. The catheter body proximal to the balloon has a diameter which is sufficiently small to allow the catheter shaft to be slidably disposed within the working channel of a flexible cystoscope. The flexible cystoscope can be utilized to allow the physician performing the dilatation to observe the external sphincter to ensure that there is no dilation thereof.Type: GrantFiled: July 6, 1992Date of Patent: November 23, 1993Assignee: Advanced Cardiovascular Systems, Inc.Inventor: Gary H.
