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.

A workstation having a pair of posts on either side of a clamping plate where a donor bone may be placed on sequentially cut in three separate cutting paths. Cutting gates are attached to the posts and used to provide cutting paths that can be precisely oriented with respect to the meniscus of the donor bone part using visual alignment without any manual measurements. The graft is affixed to a machining clamp and shaved to appropriately shape the sides and form a radius on the bottom of the graft. A tibia is then prepared by using a drill guide to form a pilot hole and then to drill out a large hole for the graft. The drilled hole is expanded and shaped using a rod guide and chisel and then a rasp. The shaped graft may then be implanted into the shaped hole and sutured in place.

Embodiments of the present invention disclose micro-lipo needle device and methods of making and using the same.

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.

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.

A blood vessel dissecting device is disclosed, which includes a dissecting device configured to be inserted into a living body along a blood vessel to dissect tissue surrounding the vessel from tissue surrounding the vessel in a direction along a longitudinal extent of the blood vessel; and a cutting device configured to fee inserted into the living body along the longitudinal extent of the blood vessel to cut the tissue surrounding the blood vessel so the direction of longitudinal extent of the blood vessel.

A process and system of compatible cannulas with features that are linked and intentionally related including the Interior Cross Sectional Area (302) of the cannulas, the area of the opening(s) of the cannulas and the width of the opening(s) of the cannulas (303). When used in a method where the appropriate harvesting cannula (100) is selected for use with a desired reinjection cannula (100), the cannula kit (FIG. 8) provides increased benefit for maintaining live tissue viability, and minimizes the time of the surgical procedure. The cannula (100) as a kit or set (FIG. 8) is used for harvesting and for reinjection, and serves in extracting, processing and transferring adipose tissue.

A bone harvesting device includes a main body having an internal cavity and a suction port adapted to be coupled to a suction source. The device further includes an outer tube (200) having an interior surface, an exterior surface, a proximal end and a distal end, the proximal end of the outer tube being coupleable to the main body, an inner tube having an interior surface, an exterior surface, a proximal end and a distal end, the inner tube being in fluid communication with the internal cavity and at least partially disposed within the outer tube such that a venting channel is defined between at least a portion of the inner tube and at least a portion of the outer tube.

A cell transplantation device is used to place a graft containing cells into a target region in a living body. The cell transplantation device includes a needle extending in one direction, and a filter unit made of a fibrous member. The needle has a flow channel defined therein and an opening at the tip of the needle. The filter unit is disposed at an intermediate position in the flow channel and configured to retain a graft between the filter unit and the opening when a liquid material containing the graft enters the flow channel through the opening.

An in-situ non-reversed femoral-popliteal bypass procedure is provided, the procedural method embodies harvesting a portion of a saphenofemoral junction as the anastomosis for said in-situ non-reversed femoral-popliteal bypass, wherein a portion of the common femoral vein is the patch of the proximal end of the anastomosis. The practitioner may intubate the anastomosis through its distal end with an expandable balloon- prior to grafting said proximal end to the femoral artery; and selectively expanding the expandable balloon at or near said proximal end.
