摘要： The disclosure describes an elongated housing, e.g., a catheter, configured to be inserted into a lumen of a patient to diagnose or treat a patient. The elongated housing includes a scope channel that accepts a cystoscope and a viewing window at the distal end of the elongated housing. The user may use the cystoscope to view tissue adjacent to the viewing window. The viewing window may take up at least 10 percent of the length of the elongated housing to allow the user to identify a large area of tissue in the lumen without moving the elongated housing with respect to the tissue. Once the user identifies the target tissue, the user may position the elongated housing using graduations on the viewing window and the proximal end of the elongated housing. An ablation needle electrode may be extended into the target tissue to deliver ablation therapy to the target tissue.
摘要翻译：本公开描述了细长的壳体，例如导管，其构造成插入患者的内腔中以诊断或治疗患者。细长的壳体包括在狭长的壳体的远端处接纳膀胱镜和观察窗的观察通道。用户可以使用膀胱镜观察邻近观察窗的组织。观察窗口可以占据细长壳体的长度的至少10％，以允许使用者在腔中识别大面积的组织而不使细长壳体相对于组织移动。一旦用户识别目标组织，用户可以使用刻度在定位窗和长形壳体的近端上定位细长壳体。消融针电极可以延伸到靶组织中以将消融治疗递送到靶组织。

摘要： The present invention is an actuator for a piston pump that includes a separately formed piston (62) and armature (60). The piston and the armature are later assembled together or are inserted into the piston pump in such a manner as to cooperate during pumping. Assembling the piston and the armature as separate components may provide for improved form of the piston component when manufactured separately from the armature, due to, for example, increased simplification of the manufacturing process. In addition, effects of manufacturing the piston and the armature together, such as stress on the piston, may be reduced.
摘要翻译：本发明是用于活塞泵的致动器，其包括单独形成的活塞（62）和电枢（60）。活塞和电枢后来组装在一起，或者以在泵送过程中配合的方式插入到活塞泵中。将活塞和电枢组装为单独的部件可以提供与电枢分开制造时的活塞部件的改进形式，这是由于例如制造过程的简单化。此外，可以减少将活塞和电枢一起制造的影响，例如活塞上的应力。

摘要： The disclosure describes a method and a system that may be used to provide feedback regarding the flow of fluid during ablation therapy. The system includes a generator that generates energy to ablate at least a portion of a target tissue, a needle that delivers the energy to the target tissue, a return electrode that receives energy dispersed from the needle, a catheter that houses at least a portion of the needle, a pump that delivers a fluid to the target tissue via the catheter, a sensor that detects a fluid parameter indicative of at least one of flow or pressure of the fluid, and a processor that analyzes the fluid parameter detected by the sensor. The sensor may be located between the pump and the target tissue. The fluid parameter detected by the system may be pressure or flow. In particular, the system may be used to treat benign prostatic hypertrophy.

摘要： A piston pump includes an actuator member (59) with a piston (62) that articulates between a retracted and a forward position in a piston channel (38). Movement between the retracted and forward position, a pumping stroke, expels a known quantity of fluid. Because of manufacturing tolerances, the forward position may not exactly line up with the end of the piston channel, resulting in dead space, or ullage, that results in less than desired accuracy for fluid volume pumped. Utilization of an adjustable stop (87) that contacts the actuator member at the desired forward position allows for selective elimination of the ullage and precise adjustment of the fluid pumped.
摘要翻译：活塞泵包括具有活塞（62）的致动器构件（59），该活塞在活塞通道（38）中的收缩位置和向前位置之间铰接。在缩回和向前位置之间的运动，泵送冲程，排出已知量的流体。由于制造公差，前进位置可能不会精确地与活塞通道的端部对齐，导致死空间或空位，导致泵送的流体体积的期望精度低于期望精度。利用在期望的前进位置处接触致动器构件的可调止动件（87）允许选择性地消除泵送的液体的空隙和精确调节。

摘要： The disclosure describes a hand-held device that utilizes a mechanical lever system to operate the device with a single hand. The mechanical lever system is coupled to a sliding element within the housing of the hand-held device that slides linearly. The sliding element may be attached to another element that is extended, retracted, or rotated in or out of the device. For example, the hand-held device may be used for prostate ablation therapy. The hand-held device may include an ablation needle electrode that is extended out of a catheter and into a tissue of a patient by depressing an extension lever of the mechanical lever system to deliver ablation therapy. Depressing a retraction lever of the mechanical lever system may retract the needle electrode back into the catheter of the hand-held device. Other variations of the mechanical system and applications of the hand-held device are also described.

摘要： The disclosure describes a method and a system that may be used to provide feedback on the progress of ablation therapy. The system includes a first needle that penetrates a target tissue to deliver radio frequency energy, with or without a conductive fluid, that heats and ablates the target tissue and a second needle that penetrates the target tissue and detects a tissue property indicative of the ablation progress. Temperature, impedance, or another parameter may be the tissue property detected and measured by the system. In addition, more than one sensor may be positioned on the first or second needle. The system may provide real-time monitoring of the tissue property or use the tissue property measurement to automatically terminate the ablation therapy. In particular, the system may be used to treat benign prostatic hypertrophy.
