摘要： An endoscopic suturing system and method are disclosed as are devices for use with the system and method such as a suture dispenser, a cinch device, and a tissue grasper. In one embodiment the suturing system includes a cap assembly arranged at the distal end portion of an endoscope or guide member, with the cap assembly including a rotatable needle holder. The needle holder is actuated through a transmission element extending outside the endoscope or guide member. A needle capture device may be inserted through a channel of the endoscope or guide member in order to capture a needle held in the needle holder when the needle holder is rotated so that the needle punctures tissue.

摘要： An instrument for performing thorascopic repair of heart valves includes a shaft for extending through the chest cavity and into a heart chamber providing access to a valve needing repair. A movable tip on the shaft is operable to capture a valve leaflet and a needle is operable to penetrate a capture valve leaflet and draw the suture therethrough. The suture is thus fastened to the valve leaflet and the instrument is withdrawn from the heart chamber transporting the suture outside the heart chamber. The suture is anchored to the heart wall with proper tension as determined by observing valve operation with an ultrasonic imaging system.

摘要： A surgical visualization system is disclosed. The surgical visualization system is configured to identify one or more structure(s) and/or determine one or more distances with respect to obscuring tissue and/or the identified structure(s). The surgical visualization system can facilitate avoidance of the identified structure(s) by a surgical device. The surgical visualization system can comprise a first emitter configured to emit a plurality of tissue-penetrating light waves and a second emitter configured to emit structured light onto the surface of tissue. The surgical visualization system can also include an image sensor configured to detect reflected visible light, tissue-penetrating light, and/or structured light. The surgical visualization system can convey information to one or more clinicians regarding the position of one or more hidden identified structures and/or provide one or more proximity indicators. In various instances, a robotic camera of the surgical visualization system can monitor and track one or more tagged structures.

摘要： An implant manipulator may have a distal end that retains an implant, a proximal end, and an intermediate portion between the ends. The implant manipulator may be a needle for a suture passer, with a suture capture feature at the distal end. The suture capture feature may have first and second members that flex apart to permit entry of the suture into a suture capture hole wherein the suture is retained until released. A suture passer may include one or more needles. The suture passer may also include a pusher; a distal end with a sharp, blade-like extension; or a side-loading distal end.

摘要： A surgical access assembly comprises a trocar and a surgical instrument. The trocar comprises a housing and an access tube extending distally from the housing. The housing comprises a hollow light emitter. The housing and the access tube define a lumen extending through the housing and the access tube. The hollow light emitter is configured to project light in the lumen. The surgical instrument comprises an end effector and a shaft extending proximally from the end effector. The shaft comprises an optical receiver positioned within reach of the light from the hollow light emitter. The shaft further comprises a light guide extending from the optical receiver along at least a portion of the shaft toward the end effector.

摘要： A method for treating a tumor at least partially within an organ in a subject's body. The method comprises volumetrically compressing the tumor to increase a pressure within the tumor above a threshold level to cause ischemia of the tumor; and maintaining the pressure above the threshold level for a period sufficient to cause necrosis in the tumor. The method may include passing a tension member within the organ around a predetermined volumetric region encompassing at least a portion of the tumor. The method may include tightening the tension member to cause compression of the volumetric region, thereby directly increasing a pressure within the tumor. The method may include maintaining the increased pressure such that most or all tissues of the tumor undergo ischemia and/or necrosis resulting directly from the compression caused by the tightened tension member.
