Abstract: An orthopedic drill bit that is configurable to form a first bone tunnel having a first bore when inserted through a bone and a second, larger bore as the drill is partially withdrawn from bone to produce a reverse counterbore for accepting an anchor. The drill bit has a shaft with a pivotal cutting tip that is movable from a narrow boring configuration into a wider boring configuration. The drill bit has a body enclosing the shaft that is biased into engagement with the cutting tip. Rotation of the body allow a user to move the cutting tip from the narrower bore configuration used to drill a pilot hole into a wider bore configuration used to drill a reverse counterbore for accepting the anchor.

Abstract: A surgical screw for fixation into bone or soft tissue. The surgical screw includes a cannulated body having a proximal end and a distal end. The distal end of the cannulated body has a tapered tip and a plurality of threads extend around the exterior of the cannulated body. An introducer extends distally from the tapered tip and has a diameter (which can be variable or constant) which is less than a diameter of the tapered tip. The surgical screw is cannulated such that a channel extends through the body from the proximal end to (and sometimes through) the distal end.

Abstract: A drill guide assembly for accurate and stable drilling of a bone tunnel. The drill guide assembly includes a guide body having first and second ends, and a slot extending from the first end toward the second end. The drill guide assembly also includes a curved guide arm having a first arm connected at an angle to a second arm. The first arm terminates in a distal tip. The second arm has first and second sides, and is slidable within the slot of the guide body. The second arm also includes detents along its second side. A locking mechanism is attached at the first end of the guide body and in a first position, and the locking mechanism is engaged with one of the detents. The drill guide assembly also includes a clamp mechanism attached at the second end of the guide body and a guide sleeve removably extending therethrough.

Abstract: Embodiments of a negative pressure wound therapy systems and methods for operating the systems are disclosed. In some embodiments, a system includes a pump assembly, canister, and a wound dressing configured to be positioned over a wound. The pump assembly, canister, and the wound dressing can be fluidically connected to facilitate delivery of negative pressure to a wound. The pump assembly can present graphical user interface screens for controlling and monitoring delivery of negative pressure. The system can be configured to efficiently deliver negative pressure and to detect and indicate presence of certain conditions, such as low pressure, high pressure, leak, canister full, and the like. Monitoring and detection of operating condition can be performed by measuring one or more operational parameters, such as pressure, flow rate, and the like.

Abstract: Embodiments of a reduced pressure system and methods for operating the system are disclosed. In some embodiments, the system can include one or more processors responsible for various functions associated with various levels of responsiveness, such as interfacing with a user, controlling a vacuum pump, providing network connectivity, etc. The system can present GUI screens for controlling and monitoring its operation. The system can determine and monitor flow of fluid in the system by utilizing one or more of the following: monitoring the speed of a pump motor, monitoring flow of fluid in a portion of a fluid flow path by using a calibrated fluid flow restrictor, and monitoring one or more characteristics of the pressure pulses. The system can provide external connectivity for accomplishing various activities, such as location tracking of the system, compliance monitoring, tracking of operational data, remote selection and adjustment of therapy settings, etc.

Abstract: An anchoring system for a knee ligament reconstruction that can secure a graft within a bone tunnel. The anchor system includes an anchor having a tubular body extending along a longitudinal axis from a proximal end to a distal end. A conical head is fixed to the distal end of the tubular body. A series of expandable segments are positioned along the tubular body and moveable along the body into a compacted, deployed position where the segments expand radially to engage the inside of a bone tunnel. A threaded drive member may move the segments to the deployed configuration once the anchor and graft are positioned in the bone tunnel. A drive tool may be used to advance the drive member and can include a moveable shaft that pushes a strike plate out of the rear of the handle to provide an indication whether the anchor has been fully deployed.
