An apparatus for slicing a cartilage sample includes a rear cartilage support cup, a cartilage clamp, a front cartilage support, a cartilage receiving region, and a cartilage cutting element. The cartilage clamp has first and second clamp members spaced apart from and aligned in a clamping direction transverse to a longitudinal axis. The cartilage receiving region is bounded by the first and second clamp members, the front cartilage support, and the rear cartilage support cup. The cartilage cutting element is spaced rearwardly from the front cartilage support by a cartilage slice thickness, the cartilage cutting element being movable across the cartilage receiving region in a cutting direction transverse to the longitudinal axis.

An apparatus and methods are provided for a trephine bone graft harvester for extracting morselized bone from patients. The trephine bone graft harvester includes a bone cutter affixed to an outer hub. The bone cutter comprises a hollow tube having cylindrical wall and a distal cutting edge. A bone graft collector is sheathed within the bone cutter. The bone graft collector includes a distal scoop adjacent to the distal cutting edge of the bone cutter. The distal scoop is configured to move morselized bone away from the distal cutting edge. An inner hub is affixed to the bone graft collector and coupled with the outer hub. The inner hub includes a proximal shank configured to be engaged with a rotary tool suitable for applying torque to the inner hub.

A transection device including a curved tubular body extending from a proximal end to a distal end, having a wall and an internal chamber and a receiving chamber. The receiving chamber may be defined by the distal end and an opening in the wall, and said distal end may have a surface facing the receiving chamber and an outside surface comprising an elongated region. A protrusion may extend from the distal end towards the center of said opening. A cutting member may be positioned within said curved tubular body and may be moveable between an initial position and an extended position and at least a portion of the cutting member may extend into the receiving chamber. A depressible member may be configured to move the cutting member and a compression member may extend between the cutting member and the depressible member. Some embodiments may utilize an electrosurgical cutting member.

A system comprising a handpiece and drive system configured to removably couple to a proximal end of a housing. A scalpet assembly is configured to removeably couple to the housing, and includes a scalpet array comprising at least one scalpet configured for rotation. The scalpet array is configured to harvest dermal plugs via fractional resection. A collection chamber is configured to collect the dermal plugs, and to house formation of an injectable filler by mincing the dermal plugs, and mixing the dermal plugs with a carrier. The injectable filler is configured for bulk fill. The collection chamber includes a loading port, and a cannular syringe is configured to mate with the loading port to receive the injectable filler, and to deliver the injectable filler for the bulk fill.

When transplanting a plurality of ovarian tissue fragments, agglomeration of ovarian tissue fragments is prevented, angiogenesis is promoted, and engraftment rate is improved. When transplanting a plurality of ovarian tissue fragments formed by cutting ovarian tissue into a mammal, and the ovarian tissue fragments are transplanted by an injection step in which collagen gel is injected into a site to be transplanted, using collagen gel with a gel concentration of about 1%, and then a transplantation step in which the plurality of ovarian tissue fragments are inserted into the collagen gel. At this time, each of the plurality of ovarian tissue fragments may be previously encapsulated with the collagen gel.

A method is disclosed for preparing a soft tissue site, and augmenting the soft tissue site, such as the breast(s), scar, depression, or other defect, of a subject through use of devices that exert a distractive force on the breast(s) and grafting of autologous fat tissue such as domes and sealing rims for surrounding each of the soft tissue site and a regulated pump. The method for preparing the soft tissue site, and enhancing fat graft results, entails application of the distracting force to the targeted soft tissue site at least intermittently for some period of time and preferably several weeks prior to the graft procedure. A rotated aspect of the invention includes following the preparation steps by transfer of fat from other areas of the subject to the subject's soft tissue site, and then reapplication of the distractive force to the soft tissue site that received the autologous fat graft. Alternatively, fat from genetically related sources may be used, and the fat may be further processed prior to injection. Substantial soft tissue augmentation, high rates of graft survival and negligible graft necrosis (data demonstrating 80% survival and only 20% necrosis is presented) or calcification result from the practice of these methods.

The present invention relates to an integrated device for hair follicle extraction and implanting, comprising a body mechanism and a connecting mechanism, the body mechanism comprising a body supporting frame, a first motor, a transmission frame, a second motor, a clamping component, a transmission mechanism and a pushing needle, the connecting mechanism comprises a connecting head, a fixing head and a cutter head, wherein the first motor of the body mechanism controls the up and down movement of the cutter head through the cooperation of the transmission frame and the transmission mechanism, and the second motor controls the pushing needle by the rotary motion of the clamping unit, simultaneously controls the rotational movement of the cutter head through the transmission mechanism. Compared with the prior art, the invention realizes the integrated operation of hair follicle extracting and implanting, and makes the operation of hair follicle implanting more convenient.
