An RF ablation system includes an electrode element of elongate form and a cathode pad. A control unit includes a processing unit, a power unit and, optionally, a temperature sensor and/or an impedance sensor. The control unit in one embodiment carries out RF ablation in at least two phases, the first phase at a higher energy level and a second phase, after at least partial retraction of the anode element, at a second lower phase in order to close any remaining lumen within a blood clot formed within the vessel during the first phase. Other embodiments provide for sensing retraction of the anode terminal and effecting RF ablation during and/or after the retraction process in order to create a more effective occlusion barrier.

Apparatus and method for occluding a vessel by RF embolization

A detachment mechanism for an introducer assembly is designed to hold a coupling element of an implantable medical device until its desired release within a patient's vessel. The detachment mechanism includes a body portion having first and second gripper arm elements which grip onto the coupling element of the medical device. The gripper arms are naturally biased into a closed position by means of resiliency of the body element. For this purpose, an actuating device or opening element is provided which includes an enlarged head which can be pulled against tapering internal surface of the body portion of the detachment mechanism in order to force the gripper arms open, thereby to release the medical device from the introducer assembly. The detachment mechanism, being naturally in the closed configuration, reliably holds a medical device to the introducer assembly until it is desired to release the latter into the patient's vessel.

The disclosure provides a release mechanism, method of manufacturing, and method of releasing a medical device. The mechanism comprises a generally elongate shaft, an actuating member receivable in the elongate shaft, the actuating member having an interlocking position and a releasing position, and at least two opposed arms at a distal end of the elongate shaft, biased to open relative to each other, each arm comprising a gripping portion at a distal end, and at least one interlocking member. The gripping portions of the arms may define a hollow space for holding a device. The interlocking member of each arm is longitudinally spaced from the interlocking member of any other arm and extends circumferentially around the actuating member. The actuating member is longitudinally retractable from the interlocking position to the releasing position to enable the arms to open for releasing a medical device from the gripping portions.

A balloon catheter includes a balloon having a plurality of layers. The inner layer acts as a support layer to the outer layer. Embedded within the outer layer is a plurality of particles or pellets which in one embodiment provide roughening of the outer surface of the balloon. The particles or pellets, particularly in conjunction with an inner support layer, ensure maintenance of the roughened outer surface of the balloon during inflation of the balloon. In another embodiment, the particles or pellets may be radiopaque and/or echogenic with or without creating surface roughening of the balloon.

A valvuloplasty balloon assembly includes a balloon () provided with end shoulders () preferably integral with end cones () of the balloon (). The end shoulders () provide a substantially perpendicular stop shoulder () at either end of the cylindrical portion () of the balloon (). The restraining shoulders () act to hold the balloon () within a valve () of a heart (), for instance. This prevents unwanted slippage of the balloon () during a valvuloplasty procedure and thus prevents possible damage caused as a result of such slippage.
