Abstract: A delivery system for an implantable stented device having a handle with a plurality of actuation members, each actuation member connected to one or more stent attachment elements, a sheath having a proximal end attached to the handle, and a plurality of tubes extending within the sheath. The stent attachment elements extend from distal ends of the tubes. A first actuation member is configured to move a first stent attachment element proximally toward the handle and a second actuation member is configured to move a second stent attachment element proximally toward the handle, sequentially releasing specific portions of the stented device by causing distal ends of the stent attachment elements to contact an exterior of the distal ends of the tubes, thereby disengaging the first and second stent attachment elements from the stented device.

Abstract: An electrosurgical system includes a radiofrequency (RF) generator having a controller configured to detect an occurrence of a vaporization point of target tissue and a vaporization duration between commencement of delivery of the RF energy and the occurrence of the vaporization point. The controller can apply the vaporization duration to adjust a parameter during subsequent electrode activation, such as RF power level, an electrode activation sequence, a distance between activated electrodes, and a number of activated electrodes. The controller can apply the vaporization duration to determine if whether a predetermined depth of effect has been reached for use in subsequent parameter adjustments.
