Bone harvesting system including methods and devices for obtaining and / or removing osseous debris from a bone using an auger having a flexible, helical fin projecting from a shaft. In an exemplary method, a leading end region of the auger is placed into a reamed portion of a bone's medullary cavity via an entry site extending into the bone. Osseous debris is driven toward the entry site with the auger. At least a portion of the osseous debris that has passed through the entry site is collected outside the bone. In some embodiments, the leading end region of the auger is deformed by contact between the helical fin and a wall of the medullary cavity, to conform the helical fin in the leading end region to a portion of the medullary cavity.

A low-profile medical device for containing a wound or surgical site includes a ring-shaped body defining an interior, a self-sealing gel contained within the interior, and an attachment pad for removably securing the device to a patient. The device is mounted on a patient such that the body surrounds the wound or surgical site and the gel covers the wound or surgical site, inhibiting contamination to or from the wound or surgical site. A surgical instrument may access the wound or surgical site by insertion through the gel, which forms a seal around the instrument upon insertion and seals the entry site upon removal of the instrument.

A tissue puncture assembly comprises an elongated needle having a needle distal tip. A cannula has an internal lumen sized and shaped to receive the elongated needle, wherein elongated needle is slidably positionable within the internal lumen via manipulation of a handle. An anchor lumen is coupled to the elongated needle, wherein the anchor lumen is configured to movably receive a tissue anchor.

A fluid delivery catheter includes an elongated outer sheath and an elongated inner body co-axially and slidably positioned within the outer sheath. At least one anchor is positioned on a distal region of the elongated inner body, wherein the at least one anchor transitions between an expanded state and a retracted state and wherein the at least one anchor transitions between the expanded state and the retracted state based upon relative movement between the inner body and the outer sheath. A control handle is positioned on a proximal region of the fluid delivery catheter, wherein the control handle is actuated to achieve relative movement between the inner body and the outer sheath.
