A surgical instrument of a robotic surgical system includes an elongated shaft assembly, and end effector, and an instrument cassette assembly. The elongated shaft assembly has a proximal end portion and a distal end portion. The end effector is supported the distal end portion of the elongated shaft assembly. The instrument cassette assembly is supported on the proximal end portion of the elongated shaft assembly. The instrument cassette assembly includes a cassette housing and an actuator system supported in the cassette housing. The actuator system is operably coupled to the end effector for operating the end effector.

An example medical system includes a medical device configured to join the edges of the leaflets together, an elongate body configured to be navigated through vasculature to a heart valve of patient, and a plurality of tissue engagement devices extending from a distal end of the elongate body, each tissue engagement device comprising at least one clamp configured to capture leaflets of the heart valve.

This invention is an intrasacular aneurysm occlusion device with a longitudinal mesh ribbon having a series of loops or segments with distal-to-proximal variation in their sizes, shapes, or orientations. For example, loops or segments can be progressively smaller in size and/or progressively more curved as one views the series in a distal-to-proximal direction. The device may also enable a user to selectively and remotely bend, steer, or elongate the loops or segments in real time as the ribbon is being deployed into an aneurysm sac.

A manipulator including joint mechanisms each including: first and second members extending along a central axis; the second member disposed at a distal end of the first member and being swivelable relative to the first member about a swivel axis; a guide sheath extending near the central axis, a distal end of the guide sheath being fixed to the second member; a manipulation wire introduced toward the distal end of the guide sheath; and a pulley provided in the second member such that the manipulation wire is wound at least partially around the pulley to cause a distal end of the wire to change direction towards the first member, the pulley being rotatable about an axis parallel to the swivel axis; wherein the distal end of the manipulation wire is fixed to the first member near the inner surface of the through hole.

A balloon is provided for selectively moving an esophagus away from an ablation site. The balloon is received through an oral cavity and into the esophagus of a patient. A deflecting member is provided in the tube, the balloon, or both, so as to selectively distort to bend the balloon and/or the tube to move the esophagus away from the ablation site. The deflecting member may comprise at least one of a strip made of a shape memory material that is responsive to the receipt of a stimulus to deflect to a predetermined shape, a strip that is made of or contains a ferrous material and that deflects in response to the presence of a magnetic field, and a selectively tensionable cable, wire, or string. The deflecting member may be supplemented by a stiffening strip that is located in the balloon and that causes the balloon to expand circumferentially and asymmetrically when inflated.

A medical system comprises a flexible device configured to be positioned at least partially within an anatomical passageway of a plurality of anatomical passageways within a patient anatomy. The medical system further comprises a memory device including computer executable instructions. The computer executable instructions are for performing operations comprising determining a deformation force exerted by a section of the flexible device. The operations further comprise registering a model of a candidate anatomical passageway of the plurality of anatomical passageways to a model of the flexible device based on: a shape of the flexible device; and the deformation force exerted by the section of the flexible device.

The present application is directed to a medical instrument with a hollow shaft, a handle arranged at the proximal end of the shaft and a tool tip with a tool arranged at the distal end of the shaft, wherein the tool can be actuated via an actuating element mounted in the shaft, the element being in an operative connection with the handle and the tool tip being pivotable relative to the shaft via a joint mechanism, the joint mechanism having pivoting members, wherein inside the hollow shaft at least one guide device is arranged for the steering wires connecting the pivoting members to the drive. In order that the steering wires can be installed easily and without crossing, the at least one guide device is arranged coaxially on the actuating element, and the at least one a guide device is mounted on the actuating element so that it cannot rotate.

A driver module for actuating a tendon, the driver module comprising: a slider comprising a base portion, a tendon receiving portion and a body portion, the tendon receiving portion being spaced apart from the base portion and the body portion extends from the base portion to the tendon receiving portion, the module further comprising a slider receiving portion having a first end and a second end and engageable with the base portion of the slider such that the slider is moveably attachable to the slider receiving portion.

An endoscopic instrument containing a retractable tool at its end that is articulated by engaging an actuator that moves pull wires to angularly move the tip of the instrument along a plane for conducting a procedure at a target site. The tool of instrument is linearly move from an extension position to a retracted position by another actuator. The instrument provide rotational control of the tool and instrument tip portion with a rotational actuator for rotating housings that carry both pull wires and a conducting wire connected to the tool.

Provided is an instrument for surgery and, more specifically, to an instrument for surgery which can be manually operated in order to be used for laparoscopic surgery or various types of surgery.
