A surgical instrument includes an elongated shaft including an articulating segment. A jaw assembly extends from a distal segment of the elongated shaft. A first jaw member can be actuated between a closed configuration and an open configuration. An articulation cable assembly includes a first articulation cable including a first extending portion, a second extending portion spaced apart from the first extending portion, and a loop portion connecting distal ends of the first and second extending portions of the first articulation cable. A first ferrule is positioned about the loop portion of the first articulation cable. A second articulation cable includes a first extending portion, a second extending portion spaced apart from the first extending portion, and a loop portion connecting distal ends of the first and second extending portions of the second articulation cable. A second ferrule is positioned about the loop portion of the second articulation cable.

Improved methods and devices for performing an endoscopic surgery are provided. Systems are taught for operatively treating gastrointestinal disorders endoscopically in a stable, yet dynamic operative environment, and in a minimally invasive manner. Such systems include, for example, an endoscopic surgical suite. The surgical suite can have a reversibly expandable retractor that expands to provide a stable, operative environment within a subject. The expansion can be selectively asymmetric to maximize space for a tool and an endoscope to visualize a target tissue and treat the target tissue from outside the patient in a minimally invasive manner.

The present invention relates to a combination surgical kit. The surgical kit can include a plurality of tools for a medical procedure, the plurality of tools including a first set of tools and a second set of tools. The surgical kit can also include a hand/wrist positioning tray device, including a bottom tray configured to hold the first set of tools, a middle tray configured to hold the second set of tools; and a top tray including a recess configured to receive a patients hand for the medical procedure.

The disclosure provides various embodiments of catheters having articulable ends that can be used for various procedures. Embodiments of methods are also provided that can be performed with catheters in accordance with the present disclosure.

A surgical device. The surgical device may comprise a transducer, an end effector, a generator and a control circuit. The transducer may be configured to provide vibrations. The end effector may be coupled to the transducer and may extend from the transducer along the longitudinal axis. The generator may provide an electrical signal to the transducer. Also, the control circuit may modify a current amplitude of the electrical signal in response to a change in a vibration frequency of the end effector. Accordingly to various embodiments, the control circuit may detect a first contribution to a vibration frequency of the end effector, the first contribution originating from tissue in contact with the end effector. Also, according to various embodiments, the control circuit may indicate a change in a vibration frequency of the end effector.

An interventional device for cutting tissue at a targeted cardiac valve, such as a mitral valve. The interventional device includes a catheter having a proximal end and a distal end. A cutting mechanism is positionable at the distal end, such as by routing the cutting mechanism through the catheter to position it at the distal end. The cutting mechanism includes one or more cutting elements configured for cutting valve tissue when engaged against the tissue. A handle is coupled to the proximal end of the catheter and includes one or more controls for actuating the cutting mechanism.

Various devices and methods having detachable handles at a proximal end thereof for use in the working channel of an endoscope. The detachable components at the proximal end allow the endoscope to be retracted and removed over the device, while leaving the device in place for purposes such as tissue manipulation.

A surgical instrument is provided. The surgical instrument has a drill bit employable in drilling procedures wherein the drill bit is made of a plurality of radially positioned drill bits which also may be utilized as a grasping device. As a result, the drill bit may not only drill into bone, but may also be used to grasp an object, such as a portion of the body. The present surgical instrument reduces contamination which may otherwise result from switching surgical instruments from a drill to a grasping mechanism or from the need to drill multiple holes into the patient's body.

This invention is related to an anchor implantation system capable of being fixed on a bone and including an anchor and an awl. The anchor comprises an inner side, an outer side and a perforation in connection therewith, and the anchor further includes an accommodating portion and a thread portion. The accommodating portion and the thread portion are disposed at the inner side and the outer side of the anchor, respectively. One end of the awl penetrates the accommodating portion and protrudes from the perforation, and the shape of the cross section of the awl is non-circular. The awl is rotatable to drive the anchor, so that the anchor is screwed into the bone with the thread portion. The present disclosure provides a rotating awl with a non-circular shape in cross section to enlarge a pilot hole when drilling the bone, so that the anchor can be screwed into the bone while drilling.
