摘要： An electrosurgical instrument which includes opposing end effectors and a handle for effecting movement of the end effectors relative to one another. The instrument includes a housing and a pair of electrodes. Each electode preferably includes an electrically conductive surface (e.g., which can be dimensioned for sealing, clamping and/or cutting) and an insulating substrate which is dimensioned to be engageable with the end effectors such that the electrodes reside in opposing relation relative to one another. The dimensions of the insulating substrate are different from the dimensions of the electrically conductive surface to reduce thermal spread to adjacent tissue structures. The insulating substrate is made from a material having a Comparative Tracking Index of about 300 volts to about 600 volts to reduce the incidence of flashover.

摘要： A connection system which has particular advantages in medical devices such as electrophysiology catheters, and which minimizes the potential for unwanted electrical connections. A cable of the invention has a plurality of leads, with each lead terminated by a pin connector having a retractable insulative sheath so that the chance of unwanted electrical connections is minimized when the pin connector is not connected. The metal pin of the pin connector also has a nonconducting tip member to minimize the chance of short circuits.

摘要： An apparatus and method for use in performing ablation of organs and other tissues includes a radio frequency generator which provides a radio frequency signal to ablation electrodes. The power level of the radio frequency signal is determined based on the subject area of ablation. The radio frequency signal is coupled with the ablation electrodes through a transformation circuit. The transformation circuit includes a transformer having a double secondary windings that can be connected into or out of use depending upon the load condition, creating this way a high impedance transformation circuit and a low impedance transformation circuit. The high or low impedance transformation circuit is selected based on the impedance of the ablation electrodes in contact with the subject tissue. Vacuum level, impedance level, resistance level, and time are measured during ablation. If these parameters exceed determinable limits the ablation procedure is terminated.

摘要： An improved method and apparatus for facilitating removal of fat from obese, or lipodystrophic patients, by external application of electromagnetic energy. After infiltrating the proposed zone with intumescing solution, radio frequency or microwave electromagnetic energy is applied via externally placed applicators (30) to the body site of unwanted fatty tissue. The electromagnetic energy supplies heat to the fatty tissue and to the intumescing solution, aiding in subsequent fat removal by conventional, or preferably, ultrasound-assisted, or microwave-assisted, internal liposuction. Depth of tissue penetration is controllable by selection of the appropriate electromagnetic frequency and by varying the configuration of the applicators (30). Restricting the intumescing procedure to only the desired body sites subject to subsequent internal surgical intervention reduces unwanted heating of the underlying muscle or other organs. Multiple-frequency capability is incorporated in the power supply (12).

摘要： An apparatus and method are provided for precisely isolating a target lesion in a patient's body tissue, resulting in a high likelihood of "clean" margins about the lesion when it is removed for diagnosis and/or therapy. This approach advantageously will often result in the ability to both diagnose and treat a malignant lesion with only a single percutaneous procedure, with no follow-up percutaneous or surgical procedure required, while minimizing the risk of migration of possible cancerous cells from the lesion to surrounding tissue or the bloodstream. In particular, the apparatus comprises a biopsy instrument having a distal end adapted for entry into the patient's body, a longitudinal shaft, and a cutting element disposed along the shaft. The cutting element is actuatable between a radially retracted position and a radially extended position. Advantageously, the instrument is rotatable about its axis in the radially extended position to isolate a desired tissue specimen from surrounding tissue by defining a peripheral margin about the tissue specimen. Once the tissue specimen is isolated, it may be segmented by further manipulation of the cutting element, after which the tissue segments are preferably individually removed from the patient's body through a cannula or the like. Alternatively, the specimen may be encapsulated and removed as an intact piece.
摘要翻译：提供了一种用于精确地分离患者体内组织中的靶病变的装置和方法，导致当其被去除用于诊断和/或治疗时，对病变的“清洁”边缘的高可能性。这种方法有利地经常导致仅使用单一经皮手术来诊断和治疗恶性病变的能力，而不需要随访的经皮或外科手术，同时最小化可能的癌细胞从病变迁移到周围的风险组织或血液。特别地，该装置包括具有适于进入患者身体的远端的活检器械，纵向轴和沿轴设置的切割元件。切割元件可在径向缩回位置和径向延伸位置之间致动。有利地，仪器可以在其径向延伸位置中绕其轴线旋转，以通过围绕组织样本限定周边边界来将期望的组织样本与周围组织隔离。一旦组织样本被分离，则可以通过进一步操纵切割元件来分割组织样本，之后组织片段优选通过套管等从患者身体单独地移除。或者，样品可以作为完整的片段被包封和去除。
