Abstract: Particles of non-woven graft materials for use in specialized surgical procedures such as soft tissue repair and wound management procedures, methods for making the powder, and methods for repairing tissue such as neurological tissue using the powder are disclosed. The particles can advantageously be used to fill irregular shaped areas or can be used in conjunction with non-woven graft materials.

Abstract: Disclosed herein are non-woven graft materials for use in specialized surgical procedures involving nerve repair and regeneration. Some embodiments describe electrospun fiber products such as conduits, wraps, or grafts comprising a resorbable hybrid-scale matrix to facilitate nerve repair and regeneration.

Abstract: Disclosed herein are embodiments of a non-woven hybrid-scale fiber matrix sheet which can be used to improve wound healing. The non-woven hybrid-scale fiber matrix sheet may be both microporous, due to the hybrid-scale fiber matrix, as well as macroporous through the addition of cuts or perforations in the hybrid-scale fiber matrix sheet. The micro and macroporous sheet can improve biological healing at a wound site.

Abstract: A cartilage repair technique employs a cutter-tissue trap combination device to harvest cartilage tissue from a low-weight-bearing site of a subject. Cut tissue is aspirated though a lumen of a tissue cutter. The lumen includes an outer shaft having a first distal window and an inner shaft having a second distal window. Edges of the first distal window and the second distal window cooperate to provide a cutting action there-between upon rotation of the inner shaft within the outer shaft. A tissue trap coupled to the tissue cutter is configured to collect tissue shavings of a desired size to efficiently deliver the collected shavings to a repair site during surgery. The tissue trap includes a filter in a housing configured between a removable inflow chamber and a removable outflow chamber.

Abstract: Some embodiments described herein are directed to non-woven graft materials for use in specialized surgical procedures such as neurosurgical procedures, methods for making the non-woven graft materials, and methods for repairing tissue such as neurological tissue using the non-woven graft materials.

Abstract: A cartilage repair technique employs a cutter-tissue trap combination device to harvest cartilage tissue from a low-weight-bearing site of a subject. Cut tissue is aspirated though a lumen (1101) of a tissue cutter (1100). The lumen includes an outer shaft (1106) having a first distal window and an inner shaft having a second distal window. Edges of the first distal window and the second distal window cooperate to provide a cutting action there-between upon rotation of the inner shaft within the outer shaft. A tissue trap (1400) coupled to the tissue cutter is configured to collect tissue shavings of a desired size to efficiently deliver the collected shavings to a repair site during surgery. The tissue trap includes a filter (1502) in a housing configured between a removable inflow chamber (1404) and a removable outflow chamber (1406).

Abstract: Devices, systems, methods, and kits are provided for accessing and treating bone marrow lesions in intraosseous spaces of bones by reversibly coupling a drill, including a surgical power drill, to a stylet reversibly inserted within and coupled with a cannula to provide for concurrent or synchronized rotation of the stylet and the cannula when drilling into a bone. Also provided are devices, systems, methods, and kits for their use for uncoupling a stylet from a cannula once the cannula is in a desired position in a bone, removal of the stylet to provide an open lumen to the desired location in the bone, and reversible attachment of an access device to the proximal end of the cannula to deliver and/or withdraw a substance (such as bone graft substitute) from the accessed lesion.
