    Abstract: A surgical cutting instrument for cutting body tissue has an axially elongated support shaft which supports, at a distal end thereof, a back biting assembly. The back biting assembly has a ring-shaped jaw member pivotally supported by the support shaft at a distal end thereof for rearward pivotal movement toward and away from a closed cutting position. A fixed cutting block member, supported by the support shaft at a position proximally of the pivot axis of the ring-shaped member is aligned with and cuttingly engages the ring-shaped member to cut or punch any tissue within the opening of the pivotal jaw member. The fixed cutter member can have a serrated, parallel rib surface facing the moveable jaw member, with at least one serration being taller than the others for blocking the entry of tissue or other foreign objects into the space wherein the pivotable member rotates thereby to prevent blocking of that rotation by such foreign objects. The leading edge of the pivotable member is fashioned with a reduced thickness to better slip beneath and engage tissue such as, for example, meniscus tissue.

    Abstract translation: 用于切割身体组织的外科切割器具具有轴向细长的支撑轴，其在其远端处支撑后咬合组件。 后咬合组件具有环形夹爪构件，其在其远端处由支撑轴枢转地支撑，用于朝向和远离封闭切割位置向后枢转运动。 固定切割块构件由支撑轴支撑在环形构件的枢转轴线的近侧的位置处，与环形构件对准并切割地接合以切割或冲压枢转爪构件的开口内的任何组织 。 固定刀具构件可以具有面向可移动钳口构件的锯齿形平行肋表面，其中至少一个锯齿比其他锯齿更高，用于阻止组织或其它异物进入空间的可移动构件旋转从而防止阻塞 这种异物的旋转。 可枢转构件的前缘被形成为具有减小的厚度以更好地向下滑动并接合组织，例如弯液面组织。

    Abstract: A catheter based delivery system may be used for both therapeutic and diagnostic applications. The catheter based delivery system includes a catheter having a distal end. The distal end of the catheter includes several electrodes that can emit a radio frequency waveform, and may receive a signal representative of an impedance of material in the exposed to the radio frequency waveform. The radio frequency waveform may also be applied to ablate specifically targeted material exposed to the radio frequency waveform. The several electrodes may be configured as an antenna.

    Abstract: A method of closing a tissue wound includes providing a wound closure device having a first anchor, a second anchor, and a flexible member movably attached to the second anchor, positioning the first anchor against tissue, passing the flexible member across the wound, positioning the second anchor against tissue, and pulling on a free end of the flexible member to shorten a length of the flexible member between the first and second anchors, thereby closing the wound. A wound closure device includes a first anchor, a second anchor; and a flexible member connecting the first anchor to the second anchor, the flexible member being movably attached to the second anchor, such that pulling on a free end of the flexible member shortens a length of the flexible member between the first and second anchors.

    Abstract translation: 关闭组织伤口的方法包括提供具有第一锚固件，第二锚固件和可移动地附接到第二锚固件的柔性构件的伤口闭合装置，将第一锚定件抵靠组织定位，使柔性构件穿过伤口， 第二锚固件抵靠组织，并且拉动柔性构件的自由端以缩短第一和第二锚固件之间的柔性构件的长度，由此闭合伤口。 伤口闭合装置包括第一锚固件，第二锚固件， 以及柔性构件，其将所述第一锚固件连接到所述第二锚固件，所述柔性构件可移动地附接到所述第二锚固件，使得在所述柔性构件的自由端上的拉动缩短所述柔性构件在所述第一和第二锚固件之间的长度。
