摘要： An electrode sealing assembly for use with an electrosurgical instrument for sealing tissue includes first and second jaw members which are movable from a first position in spaced relation relative to one another to at least one second position for grasping tissue. The jaw members include electrically conductive sealing plates designed to selectively transmit electrosurgical energy to tissue disposed between the sealing plates. The jaw members also include a thermoelectric cooling plate having a first surface in direct contact with an outer surface of the sealing plate. The thermoelectric cooling plate includes first and second electrical connections on opposite sides of the jaw member. The first connection is configured to selectively transmit a first electrical potential and the second connection is configured to selectively transmit a second electrical potential such that heat generated by the sealing plates is transferred away from the tissue via the thermoelectric cooling plate.

摘要： An electrode sealing assembly for use in combination with an electrosurgical instrument includes first and second jaw members which are movable from a first, spaced-apart position to a second position to grasp tissue. Each of the jaw members includes an insulative housing, a thermally conductive, electrically non-conductive material and a sealing plate. The insulative housing has a series of electromechanical interfaces which mate with a corresponding series of electromechanical interfaces which extend from the sealing plate such that the sealing plates are a capable of conducting bipolar energy through tissue held between the jaw members. The thermally conductive, electrically nonconductive material is configured to encapsulate and secure the sealing plate to the insulative housing.

摘要： An apparatus for ablating body tissue, and particularly for creating linear lesions within a chamber of a patient's heart, is provided. The apparatus includes an elongate member having an ablation section which includes an infusion tube and a plurality of spaced electrodes. The infusion tube and electrodes are covered by a fluid permeable foam material, and the foam material is covered by a fluid impermeable covering having a plurality of holes formed in it. During use, the ablation section is placed against tissue to be ablated. This positioning step is facilitated because the ablation section of the inventive devices may be manipulated in various ways. When the ablation section is properly positioned, radio frequency energy is delivered to the electrodes while saline or other conductive fluid is delivered to the infusion tube. The fluid exits the infusion tube at the ablation section, contacts the electrodes, and carries RF energy from the electrodes through the foam, through the holes in the covering and into contact with the body tissue to form a burn in the body tissue.
摘要翻译：提供一种用于烧蚀身体组织，特别是用于在患者心脏的腔室内产生线性损伤的装置。该装置包括具有消融部分的细长构件，其包括输注管和多个间隔开的电极。输液管和电极被流体可渗透的泡沫材料覆盖，并且泡沫材料被其中形成有多个孔的不透液体的覆盖物覆盖。在使用期间，将消融部分放置在待消融的组织上。该定位步骤是容易的，因为可以以各种方式操纵本发明装置的消融部分。当消融部分正确定位时，将射频能量传送到电极，同时将盐水或其它导电流体输送到输注管。流体在消融部分离开输注管，接触电极，并且将来自电极的RF能量通过泡沫穿过覆盖物中的孔并与身体组织接触以在身体组织中形成烧伤。

摘要： A catheter device for creating linear lesions in endocardial tissue or other body tissue is described. The catheter includes an inner shaft telescopically received within an outer shaft. The inner shaft has one or more spaced apart electrodes along its distal section. The outer shaft member includes a fluid permeable window positionable to selectively overlay some or all of the electrodes when the relative positioning of the inner and outer shaft members is adjusted. During use, the window is positioned adjacent to the body tissue which is to be ablated and at least a portion of the electrodes are exposed through the window. RF energy is delivered to the electrodes while saline or other conductive fluid is simultaneously delivered through the infusion tube. The conductive fluid passes into contact with the electrodes, and through the window into contact with the body tissue, thereby improving the coupling of the RF energy from the electrodes to the tissue and improving the efficiency of the ablation of the tissue.

摘要： An anastomosis device for use in coupling an end of a graft vessel to a side of a target vessel. The target vessel has an opening formed in a side wall thereof for insertion of the device. The device comprises a tubular member, at least a portion thereof being radially compressible to a compressed state for insertion of the tubular member into the opening in the target vessel and expandable from the compressed state to an expanded state for engagement of an inner graft vessel surface with an inner surface of the target vessel after insertion of the tubular member into the opening in the side wall of the target vessel. The compressible portion of the tubular member has an inner surface and an outer surface defining a wall thickness therebetween. The wall thickness of the compressible portion in its compressed state is less than the wall thickness of the compressible portion in its expanded state.
