An apparatus comprises a body, a shaft assembly, an end effector, and a shield member. The shaft assembly extends distally from the body. The end effector is located at a distal end of the shaft assembly. The end effector comprises an ultrasonic blade and a clamp arm. The ultrasonic blade is configured to vibrate at an ultrasonic frequency. The clamp arm is movable toward the ultrasonic blade to compress tissue against the ultrasonic blade. The shield member is selectively movable from a first position to a second position in response to movement of the clamp arm toward the ultrasonic blade. The shield member is configured cover at least a first portion of the ultrasonic blade in the first position. The shield member is configured to uncover the first portion of the ultrasonic blade in the second position.

A surgical tool has an elongate tubular housing having an annular clamping region formed around an opening in the tubular housing. A vacuum source is operably engaged with the elongate tubular housing for providing a vacuum within the elongate tubular housing for drawing the damaged or diseased portion of a luminal body, such as an intestine, into the tubular housing. An elongate rod is provided having an annular clamping element shaped so that the intestine may be firmly clamped between the annular clamping element and the annular clamping region of the elongate tubular housing, so that the damaged or diseased portion of the intestine is entirely within the elongate tubular housing.

A device includes a handle, an apparatus for probing and cutting, and an adaptor. The handle includes one or more triggers. The apparatus for probing and cutting is connectable to the handle and includes an elongated member, a probe, and a blade. The probe and the blade are selectively deployable from the elongate member via activation of the one or more triggers on the handle. The adaptor is configured to selectively connect the apparatus to the handle in a predetermined orientation.

Disclosed herein is a medical device. The medical device includes a blade tube section, a solenoid, and a mechanical arrangement. The blade tube section includes an outer blade tube, an inner blade tube, and a cutting window at a distal end of the blade tube section. The solenoid is offset from a central axis of the blade tube section. The mechanical arrangement is between the inner blade tube and the solenoid.

A tissue resecting instrument includes an end effector assembly having a proximal hub housing, outer and inner shafts extending therefrom, and an inner core drive assembly to rotate and reciprocate the inner shaft relative to the outer shaft. The inner core drive assembly includes a proximal receiver that receives a rotational input and rotates in response and includes a seal member disposed thereon. The rotation of the proximal receiver effects rotation of a connector and reciprocation of the connector between a proximal position and a distal position. The connector is operably coupled to the inner shaft such that the rotation and reciprocation of the connector effects the rotation and reciprocation of the inner shaft. In the proximal position, the connector and the seal member establish a seal that blocks outflow. In the distal position, the connector is displaced from the seal member to permit outflow.

A catheter for removing tissue from a body lumen and for providing information relating to the body lumen. The catheter includes a tissue cutting element that rotates relative to the catheter body and is mounted to the drive shaft for imparting rotation to the tissue cutting element. An energy emitting element of the catheter rotates relative to the catheter body and is rotatable independently of the tissue cutting element.

Prosthetic valve systems for replacing a native valve exhibiting regurgitation include a support structure and a transcatheter heart valve (THV) that is separate from the support structure. The support structure can be configured to be positioned such that it extends annularly around the native valve leaflets. After the support structure is deployed around the native valve leaflets, the THV can be expanded within the support structure such that the native valve leaflets are engaged between the support structure and the THV.

An apparatus comprises a body, a shaft assembly, an end effector, and a shield member. The shaft assembly extends distally from the body. The end effector is located at a distal end of the shaft assembly. The end effector comprises an ultrasonic blade and a clamp arm. The ultrasonic blade is configured to vibrate at an ultrasonic frequency. The clamp arm is movable toward the ultrasonic blade to compress tissue against the ultrasonic blade. The shield member is selectively movable from a first position to a second position in response to movement of the clamp arm toward the ultrasonic blade. The shield member is configured cover at least a first portion of the ultrasonic blade in the first position. The shield member is configured to uncover the first portion of the ultrasonic blade in the second position.

Ablation devices useful for removing nerve and soft tissue via a minimally invasive procedure to alleviate pain are provided. The device comprises a cannula having an opening at a distal tip of the cannula, the opening configured for suction of a surgical site, and a movable tissue capture member having a portion disposed within the opening or adjacent to the cannula, the movable tissue capture member configured to capture tissue when moved in a first position. Methods for ablating nerve and/or soft tissue utilizing the ablation devices are also provided.

The present application discloses apparatuses with deployable probes and blades and exemplary methods of use. In one or more embodiments of the present disclosure, an exemplary handheld apparatus for probing and cutting is provided. Such an exemplary handheld apparatus includes an elongate member having a probe and a blade associated with a first end thereof. The probe comprises a target interaction surface and is selectively movable between a retracted state and a target acquisition state. The blade comprises a cutting edge and is selectively movable between a retracted position and an extended position. The handheld apparatus may additionally include a handle associated with the second end of the elongate member that is operably connected to the probe and the blade. In some embodiments, the disclosed handheld apparatus is sized and shaped for use in endoscopic surgeries.
