A medical device that removes an object in a body lumen, includes a rotatable drive shaft, a cutter attached to a distal portion of the drive shaft and by which the object is cut, an outer tube surrounding the drive shaft, a guide wire tube attached to a distal portion of the outer tube and having a guide wire lumen therein, a metal member attached to the guide wire tube and including a first portion that extends along the guide wire tube and includes a first recess, and a distal tip made of a resin, disposed at a distal portion of the guide wire tube, and having a distal lumen that communicates with the guide wire lumen. The distal tip engages with the first recess of the metal member.

Systems and methods can remove material of interest, including blood clots, from a body region, including but not limited to the circulatory system for the treatment of pulmonary embolism (PE), deep vein thrombosis (DVT), cerebrovascular embolism, and other vascular occlusions.

A staple cartridge comprising a tissue thickness compensator is disclosed. The tissue thickness compensator comprises an external layer and tubular elements. The tubular elements are interconnected and positioned within the external layer. The tubular elements comprise apertures defined therein and the tubular elements are configured to collapse as pressure is applied to the tissue thickness compensator by tissue during the firing motion. The apertures enable fluids from the tissue to permeate the tissue thickness compensator.

A method of cutting soft tissue in a hand to treat trigger finger involves advancing an introducer shaft into the hand to position a distal end of the introducer shaft beyond a pulley in a finger of the hand, advancing a blade along a guiding channel on an upper surface of the introducer shaft, to position a distal end of the blade at or near the distal end of the introducer shaft, and rotating a cutting surface of the blade to an orientation at or near perpendicular relative to the upper surface of the introducer shaft. The method further involves retracting the blade along the introducer shaft to cut the pulley and removing the introducer shaft and the blade from the hand.

A staple cartridge for use with a stapling device that has an actuator that is selectively actuatable in an axial direction and an anvil portion that is selectively movable between open and closed positions is disclosed. Various embodiments of the present invention include a cartridge body that movably supports first and second staple drivers. The staple drivers each support a staple thereon and serve to drive the staples into forming contact with the anvil upon actuation by the actuator. The various embodiments of the present invention enable the final formed heights of the staples to be varied so as to apply various clamping forces and pressures to soft tissue captured within the staples. In at least one embodiment, the staples can include crowns formed thereon which can be utilized to adjust or control the clamping force and/or pressure applied by the staples.

A loading unit coupleable to a surgical stapling system is disclosed. The loading unit comprises an end effector, a firing system, and a shaft assembly extending proximally from the end effector. The end effector comprises a first jaw and a second jaw movable relative to the first jaw between an open position and a clamped position. The firing system comprises a firing assembly and an indicator. The firing assembly is movable toward a distal position through the end effector in response to a firing motion from the surgical stapling system. The indicator is configured to visually communicate a position of the firing assembly to a user of the surgical stapling system. The shaft assembly is removably couplable with the surgical stapling system and comprises an open slot region aligned with the firing assembly. The open slot region extends proximally with respect to the second jaw.

Systems, instruments, and methods for minimally invasive procedures including one or more of fractional resection, fractional lipectomy, fractional skin grafting, and/or fractional scar revision are described. Embodiments include instrumentation comprising a scalpet assembly coupled to a carrier, and the scalpet assembly includes a scalpet array. The scalpet array includes one or more scalpets configured for fractional resection, fractional lipectomy, fractional skin grafting, and/or fractional scar revision. The system includes a vacuum component coupled to the scalpet assembly and configured to evacuate tissue from the a site. The carrier is configured to control application of a rotational force and/or a vacuum force to the scalpet assembly.

Systems, instruments, and methods are described in which an apparatus comprises a housing including a scalpet device. The scalpet device includes a scalpet array that includes scalpets arranged in a pattern. The scalpets are deployable from the housing to generate incised skin pixels at a target site. The housing is positioned and the scalpet array is deployed into tissue at the target site. Incised skin pixels are generated when the target site is a donor site, and skin defects are generated when the target site is a recipient site. The incised skin pixels are harvested.

A surgical stapling apparatus. Various embodiments include a rotatable elongated body that extends from a rotatable shroud on handle assembly and has a distal end configured for attachment to a disposable loading unit. The apparatus further includes a lockable rotation system for selectively locking the rotatable shroud to prevent rotation thereof about a longitudinal axis.

Systems, instruments, and methods for minimally invasive procedures including one or more of fractional resection, fractional lipectomy, fractional skin grafting, fractional scar revision, and/or fractional tattoo removal are described. Embodiments include instrumentation comprising a scalpet assembly coupled to a carrier, and the scalpet assembly includes a scalpet array. The scalpet array includes one or more scalpets configured for fractional resection, fractional lipectomy, fractional skin grafting, fractional scar revision, and/or fractional tattoo removal. The system includes a vacuum component coupled to the scalpet assembly and configured to evacuate tissue from the a site. The carrier is configured to control application of a rotational force and/or a vacuum force to the scalpet assembly.
