The palatal gingival graft harvesting device is a gripping tool for holding and manipulating palatal gingival grafts. The palatal gingival graft harvesting device includes a first arm having opposed first and second ends, and a second arm also having opposed first and second ends. The first arm and the second arm are pivotally joined to one another at a pivot joint adjacent the second ends thereof. The first end of the second arm has an opening formed therein for receiving a tip of the first end of the first arm. First and second bifurcated, U-shaped gripping jaws extend orthogonally from the second ends of the first and second arms. Central portions of the first and second arms are selectively and releasably lockable to one another to clamp the graft between the gripping jaws.

A method for collecting and filtering biological material from blood and other fluids during a surgical procedure includes: attaching a first cover including a suction port and an intake port to a collection trap; attaching a suction source to the suction port; attaching an instrument to the intake port, through which blood and tissue are suctioned and received into the collection trap; filing the collection trap with blood and tissue; removing the collection trap from the first cover; attaching a second cover to the collection trap in place of the first cover, the second cover including a suction port and a plunger, the plunger including a press head having a screen portion permitting blood and other fluids to pass; attaching a suction source to the suction port of the second cover; separating the blood from the tissue by deploying the plunger; and drawing off the blood through the suction port.

Briefly, a punch assembly, such as for removing hair follicles from surrounding tissue, along with methods utilizing the punch assembly, are disclosed. A punch assembly may include a substantially cylindrical body having a proximal end and a distal end, the substantially cylindrical body being formed about a central axis and extending distally from the proximal end. The substantially cylindrical body may include a hair follicle-receiving chamber at least partially defined by an interior wall within the substantially cylindrical body, the interior wall extending distally from the proximal end. The punch assembly may additionally include denticulations arranged at the distal end of the substantially cylindrical body. The denticulations may be beveled in a direction away from the central axis so as to form an outer cutting edge.

A coiled shaft for tissue disruption is described herein where a flexible aspiration cannula has a first portion and a second portion formed of the coiled shaft. The cannula is configured in a particular embodiment to rotate over the length of the cannula to disrupt the matrix of bone marrow without the cannula buckling or collapsing. The cannula also includes a disruption tip coupled to the coiled shaft. The disruption tip has a radiused portion along a distal tip face of the disruption tip.

Embodiments include a system comprising a cannula assembly configured for rotational fractional resection (RFR). The cannula assembly includes at least one cannula configured for rotational operation and enclosed in a depth guide configured to control an insertion depth of the at least one cannula. The depth guide includes a vacuum chamber configured to maintain vacuum to evacuate resected tissue generated by the RFR.

Unitary endoscopic vessel harvesting devices are disclosed. In some embodiments, such devices may comprise an elongated body having a proximal end and a distal end. A conical tip may be disposed at the distal end of the elongated body. In addition, the surgical instrument may include one or more surgical instruments moveable in a longitudinal direction along an axis substantially parallel to a central longitudinal axis of the cannula from a retracted position proximally of a distal end of the tip to an advanced position toward the distal end of the tip to seal and cut a blood vessel.

Embodiments include a system comprising a carrier and a cannula assembly. The carrier includes a proximal end and a distal end, and the proximal end is configured to removeably couple to a remote console. The cannula assembly, which is configured to removeably couple to the distal end of the carrier, is configured for rotational fractional resection (RFR) and includes at least one cannula rotatably coupled to the carrier and enclosed in a depth guide configured to control an insertion depth of the at least one cannula. The depth guide includes a vacuum chamber configured to form vacuum to evacuate resected tissue generated by the RFR.

The present disclosures describe devices and methods to repair cartilage defects using arthroscopic surgical methods. The disclosed devices include a cannula assembly including a cannula body, a dam seal sub-assembly disposed proximally from the cannula body, and an obturator inserted coaxially through both the cannula body and the dam seal sub-assembly; an articulated arthroscopic cutting tool; a ring curette; a square curette; a rake curette; a matrix shuttle delivery device for delivering a cell-seeded support matrix including chondrocytes; and an applicator tool.

A collector used to collect bone includes: a container body defining an interior containment space for receiving and retaining collected bone, and having at least one open end for access and removal of collected bone from the interior containment space; and a cap in covering relation to the open end of the container body such that access to the interior containment space for removal of collected bone is inhibited. The collector includes an intake port defining an opening for receiving therein a distal end of a kerrison rongeur for collecting cut bone from a cutting area thereof, and the cap includes at least one scraper for engaging and dislodging cut bone from the cutting area of a distal end of a kerrison rongeur when received within the intake port. The collector preferably is used with a kerrison rongeur for collecting cut bone therefrom.

Methods are provided for extracting bone marrow cells from bone obtained from deceased donors, for preparing the bone marrow for cryopreservation and for obtaining desired cells from cryopreserved and fresh bone marrow.
