Abstract: A laminoplasty implant system includes a spacer implant configured for insertion into an interlaminal space defined by a cut into a lamina of a vertebra. The spacer implant includes a first end and a second end, and a tunnel extending axially between the first end and the second end. The laminoplasty implant system also includes a single fastener implant configured for insertion through the tunnel when the spacer implant is inserted into the interlaminal space. The fastener implant includes a head and a fastener portion. The head is configured to abut against a portion of the spacer implant and to extend axially from the first end into the lamina of the vertebra. The fastener portion is configured to extend through the tunnel and to extend axially from the second end into a lateral mass of the vertebra.

Abstract: An atrial retraction device is disclosed. In minimally invasive mitral valve surgery, there is often the need to make a second incision in the chest to place an atrial retractor for gaining clear access to the mitral valve of the heart by a cardiothoracic surgeon. The atrial retraction device of the present invention eliminates the need for a second incision, and provides an adjustable retraction device and associated surgical adjustor that reduces patient trauma, reduces surgical time, and does not require frequent adjustments during surgery. The atrial retraction device uses an adjustable band and roller arrangement to maintain clear and unobstructed access to the mitral valve during surgery.

Abstract: A pedicle breach detection device is disclosed. When a pilot hole is created during spinal fusion surgery to facilitate placement of a pedicle screw, it is important to determine if the created hole or tract has breached the vertebrae. A breach can be dangerous to the patient and cause pain, permanent damage, and the necessity for revision surgery. The present invention uses an accelerometer based shaft and ball tip to capture low level mechanical vibrations from the shaft to provide a definitive breach alert to the surgeon using audible, visual, tactile and haptic alert de vices.
