Abstract: A method and device for inserting screws into a patient, such that when the device is removed the device does not stick to the screw. The device, being a push-off driver, may have a handle, an inner driver, and a threaded driver sleeve having a button mechanism and a plurality of spheres, and an inner sleeve. The method includes the steps of assembling a push-off driver attaching a bone screw to the push-off driver inserting the bone screw and detaching the bone screw from the driver by unthreading the threaded driver sleeve from the polyaxial screw which causes the spheres in the recess of the inner driver to back up against the start of the recess and causing the threaded driver sleeve to “push-off” the polyaxial screw from the inner driver.

The core wire includes an engaging surface region and a capture member disposed thereon, which cooperate to engage a stent such that the stent is able to be advanced or retracted with the advancement or retraction of the core wire. The engaging surface region and the capture member can generally be configured to engage the stent when a portion of the stent is disposed within the lumen of the catheter, and release the stent when no portion of the stent is within the lumen.

Abstract: An implant having an embolic portion and a braided tubular occluding portion can be delivered through a catheter and implanted in an aneurysm. The embolic portion can be an elongated embolic structure that can coil as it is inserted into an aneurysm sac. The occluding portion can be a braided tube that is shaped to encircle the elongated embolic portion during delivery and expands to form a cup shape within the aneurysm sac, nesting in the aneurysm neck when implanted. The implant can include a closure mechanism positioned between the occluding portion and the embolic portion that can serve the purpose of restricting an end of the occluding portion at the trough of the cup shape, connecting the embolic portion to the occluding portion, and/or providing a detachment feature for connecting to a delivery system.

Abstract: An implant having an elongated portion and an expandable braided sack portion can be delivered through a catheter and implanted in an aneurysm such that elongated portion loops within the braided sack, the braided sack contacts a majority or all of the aneurysm wall, and the braided sack at least partially occludes the aneurysm neck.

Abstract: An improved tibial plateau leveling osteotomy plate is contoured in its proximal head portion to more closely resemble the structure of the tibial bone segment that is cut and rotated during the procedure. The plate also preferably has screw holes in the proximal head portion that are machined through the pre-contoured proximal head portion and are designed to angle the screw in a targeted screw path with respect to the osteotomy.

Abstract: Non-load-bearing, drug-eluting components, such as a rod cover, that can be added to load bearing spinal implants.

Abstract: An orthopedic device for implanting between adjacent vertebrae comprising: an arcuate balloon and a hardenable material within said balloon. In some embodiments, the balloon has a footprint that substantially corresponds to a perimeter of a vertebral endplate. An inflatable device is inserted through a cannula into an intervertebral space and oriented so that, upon expansion, a natural angle between vertebrae will be at least partially restored. At least one component selected from the group consisting of a load-bearing component and an osteobiologic component is directed into the inflatable device through a fluid communication means.

Abstract: A balloon assist device is disclosed which includes an inner body and a balloon bonded to the inner body. The inner body extends along an axis from a proximal end to a distal end and the cross-section of the inner body partially encloses the axis. The balloon assist device also includes an inflation tube in sealed communication with the volume enclosed by the inner body and the sheath. The balloon assist device may also include a pusher for sliding the balloon assist device along the catheter. The pusher may extend parallel to the axis from the proximal end of the balloon assist device in a proximal direction. The inflation tube may also be used as a pusher. The inner body of the balloon assist device may be a split cylinder extending along the axis from the proximal end to the distal end.

Abstract: An orthopedic impacting tool comprises a motor, an energy storage chamber, a striker, and an anvil. The motor stores energy in the energy storage chamber and then releases it, causing the striker to apply a controlled force on an adapter to create a precise impact for use in a surgical setting. The tool may further comprise a combination anvil and adapter. The tool further allows forward or backward impacting for expanding the size or volume of the opening or for facilitating removal of a broach, implant, or other surgical implement from the opening. An energy adjustment control of the tool allows a surgeon to increase or decrease the impact energy. A light source and hand grips improve ease of operation of the tool.
