A radio frequency ablation catheter having the function of a movable guide wire, comparing an electric support, a catheter body and a control handle which are sequentially provided. The catheter body is provided there with a cavity for the sliding of the movable guide wire. The distal end of the movable guide wire passes through the catheter body and protects from the distal end of the electric support, a soft guide wire provided at the distal end of the movable guide wire is always kept outside the electric support. The proximal end of the movable guide wire protects from the proximal end of the catheter body and enters the control handle, then, the proximal end of the movable guide wire is fixed to a controlling member provided on the control handle or is fixed to a controlling member provided outside the control handle.

Radio frequency ablation catheter having function of moving guide wire

A radio frequency ablation device () comprising a balloon blocking catheter. The radio frequency ablation device () comprises a double or multi-lumen balloon blocking catheter () and a radio frequency ablation catheter (). a stent () is arranged at the far end of the radio frequency ablation catheter (). Two or more electrodes () are arranged on the stent (), and are connected to a radio frequency generator respectively by means of the corresponding guide wires arranged in the radio frequency ablation catheter (). When the radio frequency ablation device () is used for ablating blood vessel peripheral nerves, inflating a blocking balloon () arranged at the far end of the guide catheter () to block local blood flow in a blood vessel. The invention has ideal nerve ablation effect.

Radio frequency ablation device comprising balloon blocking catheter and ablation method therefor

The present invention provides a method of treating or alleviating erectile dysfunction in a patient. Multiple electrodes are placed within a segment of the internal iliac artery of the patient and against blood vessel wall of the internal iliac artery. Radiofrequency energy is released through at least one of the multiple electrodes to nearby tissues, so as to increase the temperature of the nearby tissues and induce a thermal alteration of the nearby tissues.

Method of treating or alleviating erectile dysfunction

The present invention provides a catheter apparatus with a carrier comprising right-handed wire helixes and left-handed wire helixes that are plainly or bi-axially woven into a tubular structure. A therapeutic assembly wraps around one of the wire helixes to stabilize an associated interstice of the tubular structure. The regular shape of the carrier may be quickly recovered after the carrier is seriously bent or distorted in an intravascular treatment.

Radiofrequency ablation catheter apparatus with meshed carrier having stabilized shape, system thereof and methods thereof

A corrugated radiofrequency ablation catheter and an apparatus thereof. The radiofrequency ablation catheter is provided with a strip-shaped connecting catheter (). An electrode frame is provided at the front extremity of the connecting catheter (). A control handle () is provided at the rear extremity of the connecting catheter (). The electrode frame is a corrugated electrode frame consisting of one or more corrugations. One or more electrodes () respectively are distributed on the corrugations. Slidable, supporting, wall-attaching adjustment wires () are provided within one lumen of the connecting catheter () and the electrode frame. The supporting, wall-attaching adjustment wires () are divided into a flexible segment () away from the control handle and a rigid segment () in proximity to the control handle.

Corrugated radiofrequency ablation catheter and apparatus thereof

Disclosed are a radio-frequency ablation catheter having a spiral structure and device thereof. The radio-frequency ablation catheter has an elongated catheter body. A spiral electrode support is arranged at the front end of the catheter body. Multiple electrodes are arranged on the electrode support. A control handle is arranged at the rear end of the catheter body. Wall-attachment adjusting wires having various structures can be arranged in the radio-frequency ablation catheter, so that the radio-frequency ablation catheter having a spiral structure can be adapted to target vessels of different diameters, and so that the electrodes on the electrode support have a good wall-attachment state.

Radio-frequency ablation catheter having spiral structure and device thereof

Disclosed are an ultrasonic surgical instrument () and ultrasonic surgical system; the ultrasonic surgical instrument () includes a waveguide () rotatable around an axis and in threaded connection with a transducer (); a force transmission mechanism is in fixed connection with the waveguide (), which has at least one stress surface (); a rotatable mechanism includes a pushing mechanism and a rotatable driving mechanism having at least one force applying surface (), the applying surface () and the stress surface () are not perpendicular to the axis, and can be engaged with each other; the pushing mechanism provides a pushing force the rotatable driving mechanism towards the force transmission mechanism, and the rotatable driving mechanism can overcome the pushing force when interaction force between the applying surface () and the stress surface () is in excess of a predetermined value.
