An exemplary surgical device includes a shaft with a lumen defined therethrough and an element movable from a stored position to a deployed position in which a larger portion of the element extends out of the distal end of the lumen; wherein motion from the stored position to the deployed position causes a first leg of the element to advance distally relative to the distal end of the shaft, and causes a second leg of the element to move proximally relative to the distal end of the shaft.

An apparatus for disrupting tissue in the intervertebral disc space that includes a barrier member having a first configuration for insertion into the disc space and a second configuration when deployed within the disc space. The second configuration of the barrier member is adapted to at least partially define a perimeter of a working region within the disc space. The apparatus also includes a tissue disruption tool configured for insertion into the working region.

A handheld rotary medical device with a shaver configured to remove cartilage is disclosed. The handheld rotary medical device may include an inner drive shaft, an elongated, tubular, outer housing encapsulating the inner drive shaft such that the inner drive shaft is positioned within the outer housing and a shaver at a distal end of the inner drive shaft. The shaver may include a plurality of teeth extending radially outward from an outer surface of the inner drive shaft. The medical device may include slots or grooves in the outer housing useful for cleaning the tissue from the teeth of the shaver.

In accordance with an aspect of the present disclosure, a tissue extraction device may include a bag having an interior and a plurality of cutting elements extending through the interior of the bag.

Methods and apparatuses for performing an orthopedic procedure in the sacroiliac region are disclosed. In one form, an aperture is formed that at least partially extends through at least one of an ilium and a sacrum. An undercutting system is inserted into the aperture. The undercutting system includes an insertion apparatus, a probe assembly and a cutting assembly. The probe assembly is moved with respect to the insertion apparatus from a retracted position to an extended position. The probe assembly is manipulated within a joint between the ilium and the sacrum while the probe assembly is in the extended position. The cutting assembly is moved with respect to the insertion apparatus from a retracted position to an extended position. The cutting assembly is manipulated within the joint between the ilium and the sacrum while the cutting assembly is in the extended position to form a fusion region.

A system configured to cut leaflet tissue at a cardiac valve may comprise a guide catheter and a cutting mechanism routable through the guide catheter. The cutting mechanism includes a cutting arm and a plurality of grasping arms rotatably coupled to the cutting arm. The grasping arms are connected to the cutting arm via a central hinge and are actuatable between a closed position against the cutting arm and an open position where the grasping arms extend laterally away from the cutting arm by rotating about the hinge. Targeted cardiac leaflet tissue may be grasped between the cutting arm and the grasping arms and cut by a cutting element that is attached to or extends through the cutting arm.

Certain aspects of the present disclosure provide an apparatus and method of using a multifunctional device to cut/tab a graft from a donor region of an eye. The apparatus includes a multifunctional device for ophthalmic surgery, having an insertion sleeve comprising an inner surface defining a compartment, a flat wire contained within the compartment folded to form a loop, wherein the flat wire comprises a sharp edge (continuous or tabbed) operable for cutting retinal tissue, and wherein the loop is positioned at a distal end of the insertion sleeve, and a handpiece coupled to the insertion tube and configured to adjust a size of the loop.

Devices and methods for performing subcutaneous surgery in a minimally invasive manner are provided. The methods include application of reduced air pressure in a recessed area of a handpiece placed over a section of skin and drawing the section of skin and subcutaneous tissue into the recessed area. In a subsequent step a tool is inserted through a tool conduit in the handpiece and through the skin into the subcutaneous tissue, enabling the performance of the desired surgery. Common surgical procedures include dissection and ablation . The devices and methods can be directed at the treatment of skin conditions like atrophic scars, wrinkles, or other cosmetic issues, at treatments like or promoting wound healing or preventing hyperhidrosis, or can be used for creating space for various implants.

The disclosure relates to a surgical device configured to both strip and cut a tendon. The harvested tendon can be used in various orthopedic procedures, such as ACL, PCL, and UCL reconstructions.

An amputation system includes a cutting element having a cutting blade traversing a V-shape. The V-shape has a vertex and an angle in a range of 90-120°. A rod, rigidly coupled to the cutting element, has its longitudinal axis aligned with the vertex so it bisects the angle of the V-shape. A barrel having a bore receives at least a portion of the rod therein wherein the rod's outboard end resides in the bore. An energetic energy source, positioned in the bore adjacent to the rod's outboard end, generates a pressure force that is incident on the rod's outboard end. The pressure force is one that peaks within 0.5 milliseconds to propel the rod from the bore at a velocity in a range of 300 to 1000 feet per second.
