The disposable outer housing is movable between an open configuration and a closed configuration. The handle assembly further comprises a control inner core receivable inside the disposable outer housing in the open configuration. The disposable outer housing is configured to isolate the control inner core in the closed configuration. The modular components further comprise a loading unit releasably couplable to the shaft and a staple cartridge releasably couplable to an end effector. The loading unit comprises the end effector. The control circuit is configured to generate an interrogation signal, detect a response signal, determine a modular configuration of the modular surgical instrument system, and assess authenticity of the modular configuration.

The present technology relates to power management for interatrial shunting systems. In some embodiments, the present technology includes a system for shunting blood between a left atrium and a right atrium of a patient. The system can include a shunting element and a plurality of active electronic components operably coupled to the shunting element. At least some of the active electronic components have different power consumption characteristics. The system also includes a plurality of energy storage components, with some of the energy storage components have different characteristics. During operation, the system is configured to receive a signal indicating that an active electronic component is to be operated, and select an energy storage component associated with power output characteristics capable of accommodating the power consumption characteristics of the active electronic component. The system is further configured to instruct the selected energy storage component to power operation of the active electronic component.

Piezoelectric osteotomy devices and corresponding systems and methods for removing an acetabular cup or shell from a patient's acetabulum are disclosed. In one embodiment, the piezoelectric osteotomy device includes a piezoelectric element to actuate a cutting tip on an armature. In some such embodiments, the cutting tip may be extended and/or retracted to facilitate cutting of bone around an acetabular cup. The armature may include a fluid output port located proximate the cutting tip to mitigate heat generated by the cutting tip. In one embodiment, the piezoelectric osteotomy device is arranged and configured to provide constant current adjustment.

Methods and systems for tuning lithotripsy frequency to target size are disclosed. In one embodiment, a lithotripsy system for comminuting a stone in a body includes: a burst wave lithotripsy (BWL) therapy transducer configured to transmit smooth ultrasound waves within a burst of ultrasound waves toward the stone; and a controller configured to determine operating frequency of the ultrasound waves of the therapy transducer. The operating frequency of the ultrasound waves is determined as:

[00001]$f=\mathrm{Const}.\frac{c}{d}$ where: d is a diameter of the stone, f is the frequency of the ultrasound waves, c is a wave speed in the stone, and Const. is a predetermined constant.

A tissue specimen removal device comprises a specimen bag; a flexible ring, the flexible ring configured to form a top opening of the specimen bag; a cannula assembly comprising: an inner tube portion and an outer tube portion. The device may further comprise a connector carrier, the connector carrier configured to retain at least one connector housing, the at least one connector housing comprising one or more connector portions and reside within an interior of the connector carrier, and wherein the connector carrier can be moved from a position within the cannula assembly to outside the cannula assembly.

Disclosed herein are apparatuses, systems, kits, and methods for treating skin, such as skin tightening or for treating diseases, disorders, and conditions that would benefit from tissue area or volume reduction, skin restoration, skin tightening, skin lifting, and/or skin repositioning and/or for generally improving skin function or appearance (e.g., the removal of unwanted skin features or irregularities such as sebaceous glands, sweat glands, hair follicles, necrosis, and fibrosis). Such apparatuses, systems, kits, and methods comprise an apparatus having a handheld main body and a detachably attachable tip comprising one or more needles.

The present disclosure relates generally to the field of medical devices. In particular, the present disclosure relates to endoscopic medical devices with distally actuated axial displacement configured to impart in-plane or rotational ultrasonic reciprocation to an end effector.

Systems and related methods for changing the angle of a bone of a subject is provided by the present disclosure. The system may include a non-invasively adjustable implant configured to be placed inside a cavity within the bone. The non-invasively adjustable implant may couple to a first portion of bone and a second portion of bone that is separated or separable from the first portion of bone, such that non-invasive elongation of the adjustable implant causes movement of the first portion of bone and the second portion of bone apart angularly. The system may include an anchor configured to couple the non-invasively adjustable implant to bone. The non-invasively adjustable implant may include an anchor hole configured to receive the anchor therein.

Transcatheter device for the treatment of calcified native heart valve leaflets comprising an outer hollow shaft (5), an inner hollow shaft (4) slidingly contained within said outer shaft (5) and an axle body (6) slidingly contained within said inner shaft (4); wherein the device comprises a commissure debridement system (7), located at the distal end of the axle body (6), that is made of at least two radially expandable arms (7) that are adapted to be inserted in and aligned with native commissures.

A surgical instrument comprising a housing, a shaft, a loading unit, a firing member configured to perform a firing stroke, a motor, a battery, a firing trigger, a control system, an electronic lockout, and a firing trigger lockout is disclosed. The electronic lockout is configured to prevent the firing member from performing the firing stroke when the loadinq unit is not attached to the shaft. The electronic lockout is further configured to prevent the firing member from performing the firing stroke when the loading unit is attached to the shaft and the loading unit has been at least partially fired. The firing trigger lockout is in a locked position when the loading unit is not attached to the elongate shaft. The firing trigger lockout is in the locked position when the loading unit is attached to the elongate shaft and the loading unit has been at least partially fired.
