Abstract: A thrombectomy device including a handle, a catheter and a cutting assembly at the distal end of the catheter. The thrombectomy device includes two oppositely wound helical wires, whereupon rotating in opposite direction, the helical wires cooperate to convey thrombus material form the distal end of the catheter to the proximal end of the thrombectomy device without the thrombus material adhering to the inner lumen of the catheter.

Abstract: A wire connector assembly for an ultrasonic therapy catheter system including an ultrasound generator is presented. The wire connector assembly includes a sonic connector that is configured to couple to the ultrasound generator and receive ultrasonic energy therefrom. The sonic connector includes a body having a passageway that extends therethrough, and the passageway includes a tapered surface. The wire connector assembly further includes a wire that engages the tapered surface and extends outwardly from the passageway. The wire is configured to receive ultrasonic energy from the sonic connector.

Abstract: A vapor delivery needle is provided that may include any of a number of features. One feature of the energy delivery probe is that it can apply condensable vapor energy to tissue, such as a prostrate, to shrink, damage, denaturate the prostate. In some embodiments, the vapor delivery needle can be advanced a predetermined distance into the prostate by an actuation mechanism. The actuation mechanism can comprise, for example, a spring, or at least one magnet. Methods associated with use of the energy delivery probe are also covered.

Abstract: A method of using an ablation device to ablate tissue at a desired location, wherein the ablation device comprises: a pair of floating jaws moveable between a spaced apart open position and a closed position, the pair of jaws comprising at least one ablating element for ablating tissue located between the jaws; a handle comprising controls for remotely controlling the movement of the jaws and the at least one ablative element; and a flexible neck connecting the jaws and handle, wherein the neck is flexible so as to permit the jaws to be maneuverable in the body with respect to the handle; the method comprising the steps of: providing the ablation device; delivering the jaws to a desired location; positioning the jaws in the open position around tissue desired to be ablated; closing the jaws to the closed position on the tissue by using the controls on the handle portion of the ablation device; and activating the at least one ablating element by using the controls on the handle portion of the ablation device a

Abstract: A hemostat-type device for ablative treatment of tissue, particularly for treatment of atrial fibrillation, is constructed with features that provide easy and effective treatment. A swiveling head assembly can allow the jaws to be adjusted in pitch and roll. Malleable jaws can permit curved lesion shapes. A locking detent can secure the jaws in a closed position during the procedure. An illuminated indicator provides confirmation that the device is operating. A fluid delivery system simplifies irrigated ablation procedures.
