Abstract
A medical device for heat treatment of patient tissue includes an electrically conductive wire guide. The wire guide has a distal end and a proximal portion. A connector is disposed on the proximal portion of the wire guide for providing electrical power to the wire guide, thereby enabling the distal end of the wire guide to heat the patient tissue.
Claims34
A medical device for heat treatment of patient tissue, the medical device comprising:
- an electrically conductive wire guide, the wire guide having a movable core, a distal end and a proximal portion;
- and
- a removable connector disposed on the proximal portion of the wire guide for providing electrical power to the wire guide, thereby enabling the distal end of the wire guide to heat the patient tissue,
- wherein the medical device is configured for stiffness for use as an electro-surgical unit, and is configured for flexibility for use as a wire guide.
A medical device suitable for minimally-invasive medical procedures, comprising:
- a) a wire guide having a movable core and a proximal and a distal portion, the distal portion configured for stiffness for use as an electro-surgical unit and configured for flexibility for use as a wire guide;
- b) a connector, the connector disconnectably connected to the proximal portion of the wire guide;
- and
- c) a power source disconnectably connected to the connector, wherein the medical device is configured for use as an electro-surgical unit when the connector is present and as a wire guide when the connector is removed.
A catheter suitable for minimally invasive medical procedures, the catheter having a distal tip and a proximal portion, comprising:
- (a) a wire guide having a movable core and a proximal and a distal portion, the distal portion configured for stiffness for use as an electro-surgical unit and configured for flexibility for use as a wire guide;
- (b) a connector, the connector disconnectably connected to the proximal portion of the wire guide;
- (c) a power source disconnectably connected to the connector;
- and
- (d) wherein the distal portion of the wire guide terminates within 50 mm of the catheter distal tip, and wherein the catheter is configured for use as an electrosurgical unit when the connector and power source are connected to the wire guide, and is configured for use as a wire guide when the connector and power source are disconnected from the catheter.
