Abstract: A hybrid spinal implant device, and method of making the same are disclosed. The spinal implant device comprises two facing endplates, each having at least one anchoring wall or pin element, and a plastic spacer anchored to and located between the two endplates. The endplates may be manufactured from titanium. The plastic spacer may be manufactured from a radiolucent, and bio-compatible polymer-based material including polyetheretherketone (“PEEK”), polyetherketone, polyetherketoneketone, and/or fiber reinforced plastic. The endplates made of titanium allow for enhanced bone growth, while the plastic/PEEK spacer element allows for improved load absorption and distribution. The spinal implant device, using titanium endplates and a PEEK spacer, provides excellent radiolucency thereby eliminating the need for X-ray markers either intra- or post-operation. The manufacturing method for the hybrid spinal implant device uses injection molding to insert or back injection mold the spacer between the two endplates.

Abstract: A surgical scalpel, scalpel instrument and/or scalpel system (collectively, scalpel), is configured for use in a transverse carpal ligament surgical procedure. The scalpel evaluates an incision path with respect to a nerve in the incision path, and performs the incision if appropriate. The scalpel emits a signal through a potential incision path through tissue captured by the scalpel. The scalpel utilizes the emitted signal to determine whether a nerve is in the incision path. The surgical instrument includes a retractable blade. Evaluation includes determining whether a nerve is present before incision and/or evaluating whether the target tissue has been appropriately captured. A warning is provided when a nerve is in the incision path and/or the captured target tissue is inappropriate. The surgical instrument disables extension of the blade when a nerve is in the dissection path and/or the captured target tissue is inappropriate.

Abstract: Methods, systems, and devices are provided for monitoring and displaying medical parameters for a patient. In one embodiment, a display screen can include information related to a physiological parameter being measured from a patient. The information can include a current value based on values of the physiological parameter gathered from the patient over a period of time. The display screen can indicate whether or not the current value is within a predetermined normal range for the physiological parameter and whether or not the current value is within a predetermined goal range for the physiological parameter. The goal range can be nested within the normal range. If the current value moves outside the normal range, an alarm can be triggered. A goal alarm can be triggered if the current value is within the normal range but falls outside the goal range.
