    摘要： Two embodiments for a stent delivery device are disclosed. In the first embodiment, the stent delivery device comprises an outer sheath and an inner tubular member which distally ends in a tongue having an arcuate cross section. In a second embodiment, the stent delivery device further comprises a housing having a lumen extending longitudinally therethrough, the lumen holding the inner tubular member. A guide pin attached to the outer sheath is slidably disposed within the housing wherein the guide pin may be longitudinally displaced with respect to the lumen. In addition, an endoscope mounting plate may be slidably disposed along the housing. Detents may be used to releasably prevent a proximal displacement of the guide pin within the lumen of the housing as well as to releasably prevent the proximal displacement of the endoscope mounting plate with respect to the housing.

    摘要： A stent delivery system for use in placing a stent within the prostatic urethra and ensuring that the stent does not interfere with the closure of the bladder neck sphincter. The delivery system includes a catheter with an anchor which anchors the catheter within the urethra and ensures placement of the stent at a predetermined distance from the bladder neck sphincter. For use with shape memory stents, the catheter includes a warming fluid system in which the endoscope used in the procedure can act as a fluid supply line and as valve spool to control the flow or warming fluid to the stent.

    摘要： The system for providing computer guided ablation of tissue of a patient includes an ablative surgical computer system and a set of surgical devices. The ablative surgical computer system includes a guidance module for providing a treatment guidance plan to an operator; and, a treatment module for acquiring and processing surgical device output data, for optimally controlling treatment parameters and providing feedback information to the operator based on the treatment guidance plan. The set of surgical devices includes at least one ablative device for providing ablation of the treatment region based on the treatment parameters and operator input; and, at least one temperature sensing device for acquiring temperature data from the treatment region and providing a temperature sensing device output signal. The temperature sensing device output signal is a portion of the surgical device output data. The treatment guidance plan is utilized for placing the ablative device and the temperature sensing device into the treatment region.

    摘要： A stent system and method for use in the prostate gland. The stent is made of a shape memory alloy such as nitinol, and has a low temperature martensite state, with a martensite transition temperature below body temperature, and a high temperature austenite state, with an austenite transition temperature at or above body temperature, and a memorized shape in the high temperature austenite state which is a helical coil of diameter large enough to hold the prostatic urethra open. The stent is used to heat the prostate and is left in the prostatic urethra while the prostate heals. After the prostate is substantially healed, the stent is cooled to its martensite state and is easily removed from the urethra.

    摘要： A placement guide for positioning ablation devices within a human body is disclosed. The placement guide comprise an outer catheter and an inner tubular member disposed within a lumen of the outer catheter. When a stop on the inner tubular member engages a seat on the outer catheter, a distal projection of the inner tubular member extends from the distal end of the outer catheter. While monitoring the position of the inner tubular member through an endoscope inserted in its lumen, a clinician positions the distal projection within a human body for optimal ablation. After securing the outer catheter in position, the inner tubular member is withdrawn and replaced with an ablation device which is inserted distally within the outer catheter lumen until a stop on the ablation device engages the seat on the outer catheter wherein a distal projection of the ablation device extends from the distal end of the outer catheter. Because the distal projection of the inner tubular member has a length substantially identical to that of the inner tubular member, the ablation device may be positioned for optimal ablation.

    摘要翻译： 公开了一种用于将消融装置定位在人体内的放置引导件。 放置引导件包括外导管和设置在外导管的内腔内的内管状构件。 当内管状构件上的止动件与外导管上的座接合时，内管状构件的远端突出部从外导管的远端延伸。 在通过插入其管腔中的内窥镜监测内管状构件的位置的同时，临床医生将远侧突出物定位在人体内以进行最佳消融。 在将外导管固定就位之后，内管状构件被取出并且被切除装置替代，该消融装置向远端插入外导管内腔中直到消融装置上的止动件接合外导管上的座，其中消融的远侧突出部 装置从外导管的远端延伸。 因为内部管状构件的远侧突出部具有与内部管状构件的长度基本相同的长度，所以可以定位消融装置以实现最佳消融。
