Abstract: The present invention relates to a treatment apparatus using high frequency waves, and to a method for controlling same. The treatment apparatus using high frequency waves comprises: a high frequency wave generating unit; a plurality of needles for providing, into the skin of a user, high frequency energy transferred from the high frequency wave generating unit; and a driving unit for inserting the plurality of needles into the skin of the user, wherein the apparatus further comprises a control unit for controlling the driving unit such that the plurality of needles are inserted into a first target point within the skin and then move to a second target point.

Abstract: A medical electrical lead includes a proximal connector including a rotatable portion and first and second co-radial conductors coupled to the rotatable portion and extending distally from the rotatable portion. An actuation member is coupled between an electrode and the first and second conductors such that rotating the rotatable portion of the proximal connector transmits torque through the co-radial first and second conductors to the actuation member and results in both rotational and linear motion of the electrode.

Abstract: The invention provides an applicator for skin treatment having one or more RF electrodes. An article is located between the electrodes, such as a roller or flexible belt containing one or more protruding pins electrically isolated from the RF electrodes. The invention also provides a system for skin treatment comprising the applicator of the invention and a control unit. The invention further provides a method of treating skin disorders in which a section of the skin is heated while, essentially simultaneously, piercing one or more holes in the heated section of the skin. The method of the invention may be used, for example, in collagen remodeling.

Abstract: The invention provides improved devices, methods, and systems for repeatably and reliably contracting fascia and other support tissues, particularly for the treatment of urinary incontinence. Rather than relying on a surgeon's ability to observe, direct, and control the selective shrinking of pelvic support tissues, probes generally limit heating so that only sufficient controlled energy is transmitted from a surface of the probe into the engaged tissue to contract the tissue and inhibit incontinence (or otherwise provide the desired therapeutic results).

Abstract: An apparatus for treating skin disorders includes a case, an electrode structure having a metal ball tip electrode for contacting the skin, and a metal electrode mounted on a handle portion of the electrode structure. The electrode structure can be conveniently grasped with one hand.

Abstract: An electrosurgical instrument includes an electrode assembly having an electrode mechanically interlocked with a non-conductive body to as to form a gap therebetween. In one embodiment, complimentary surface features of the respective electrode and the non-conductive body interlock the components of the electrode assembly. In another embodiment, the electrode assembly includes a generally spherical electrode that is rotatable with respect to a non-conductive hood. A gap is formed between an outer surface of the electrode and an inner surface of the hood.

Abstract: An electrocautery probe includes a single probe arm and an electrode. The electrode includes one end attached to the probe arm and a free end. According to one embodiment of the invention, the electrode is a wedge, preferably having a substantially triangular cross section. According to another embodiment of the invention, the free end of the electrode rises higher than the attached end of the electrode. The free end of the electrode may be planar, pointed, or rounded. Where the free end of the electrode is planar, it may be inclined in either the proximal or distal direction. According to yet another embodiment of the invention, the electrode is a roller barrel. The electrocautery probe has several advantages over two armed electrocautery probes. First, the electrocautery probe has only one arm obscuring the physician's view through the lens of the resectoscope. Second, the free end of the electrode can be used for sculpting tissue and for resecting tissue in narrow areas.

Abstract: An electrocautery probe includes a pair of arms between which a roller electrode is mounted. The arms are joined at their proximal ends to an electrode lead and a mounting sleeve is provided intermediate of the arms and the lead for slideably coupling the probe to a resectoscope. According to the invention, the roller electrode has an eccentric convex or concave surface to increase the surface area of the electrode. In other embodiments of the invention the electrode is provided with a plurality of longitudinal surface grooves which further increase surface area of the electrode and also enhance traction of the electrode. The electrodes according to the invention are preferably made of copper, chromium cobalt, or carbonless stainless steel. They preferably have an overall diameter of from about 0.115 to about 0.187 inches and an overall length of from about 0.110 to about 0.120 inches.

Abstract: A "V" shaped grooved roller forming part of an electrode for use with a resectoscope is shown. The electrode includes an electrode lead member having an elongated conductor member. The elongated conductor member has a first end and a second end with an insulative cover extended therebetween. The first end has a protruding electrode adapted to be electrically connected to an electrosurgical generator and the second end terminates in an active member. An electrode support member is operatively connected to the active member. The electrode support member has an elongated semi-rigid bifurcated arm terminating in a conductive core spaced a predetermined distance from the active member. The bifurcated arm is covered with an insulative material except at the distal end where the grooved roller is located. The electrode support member has a grooved roller having an outer surface and at least one circumferentially extending "V" shaped slot formed in the outer surface thereof.
