Abstract: A method of forming a composite titanium body for use in forming spinal implant interbodies includes selecting a metal alloy body, carving out a top portion and a bottom portion from the metal alloy body, and bonding a porous material to the carved-out top and bottom portions. Multiple pieces may be cut from the composite titanium body, each having a front face formed of the metal alloy, top and bottom portions formed of the porous material, and with a medial portion of the metal alloy extending from the front face to the back. Methods and devices for spinal interbodies having locking mechanisms to prevent bone screw back-out are also described.

Abstract: In various aspects, an implant includes a body having a lattice structure, with the lattice structure extending continuously from a superior surface of the body to an inferior surface of the body.

Abstract: A pressure sensing clip (1) and a system including a bandage (19) for detecting and displaying the pressure applied by a (compression) bandage (19) to a human or animal body in which the pressure sensing clip (1) has an inner bandage penetrating arm (2) and an outer arm (3) hingedly attached to the inner arm (2) at a hinge (4) so that the outer arm (3) is movable between a hingedly closed position with respect to the inner arm (2) and a hingedly open position. The device can be operatively attached to an applied compression bandage, or it can be placed beneath or between the bandage during bandage application so that the bandage covers the sensing part of the device. In the latter application, the ability of the arms of the device to adapt an open configuration allows the bandage to be applied over the inner arm leaving the outer arm to close once the bandage has been applied. The device can receive, store and transmit data to a user.

Abstract: A system and method for asset registration and tagging includes determining candidate devices on a network or subnet. Device information is pulled from discovered devices. Device records are stored with device information including device serial number, model number, asset ID and service record information. A QR code is generated and displayed or printed at each discovered device. A device user scans the QR code to supply location information, as well as other user input, which is added to the device information. A device is then registered and an asset tag is printed at the device with instructions to affix it on an exterior for future reference.

Abstract: An implantable medical device having a soft tissue interfacing surface comprises at least one soft actuatable capsule having a soft tissue interfacing deflectable membrane configured for cyclical deflection upon actuation of the capsule to modulate the biomechanics of the soft tissue interface during use. The actuatable capsule may comprise an actuation chamber containing a first fluid, a therapeutic chamber containing a second fluid, a deflectable membrane separating the actuation chamber and therapeutic chamber, and an actuation conduit in fluidic communication with the actuation chamber for pneumatic actuation of the actuation chamber. The therapeutic chamber comprises the soft tissue interfacing deflectable membrane which is configured to cyclically deflect during actuation of the capsule and modulate the biomechanics of the soft tissue interface by altering one or more of strain, fluid flow and cellular activity in peri-implant tissue at the soft tissue interface.

Abstract: This invention relates to an apparatus for monitoring a locally attached printer using the locally attached printer's Ethernet interface. A USB device is installed between a computer and a locally attached non-networked printer and additionally connects to the printer via an Ethernet interface. The USB device uses SNMP (or other network protocols) to manage the printer via the Ethernet interface. The system may then report the management information to a central server.
