Abstract: The invention relates to a medical system comprising a tool including: a body; a location measurement device adapted to emit an ultrasound location signal and receive a reflected location signal; a location processing device adapted to compare each of the echoes of the reflected location signal to a pre-determined location threshold, emit an information signal if no target location echo corresponding to the interface between first and second anatomical structures has been identified within an analysis time window, the target location echo having an amplitude that exceeds the location threshold.

Abstract: A surgical retractor includes a body portion and first and second retractor arms operatively coupled thereto. The body portion includes a rotatable knob, a first blade holder, and a first blade. The first blade is configured for axial displacement with the first blade holder and angulation relative to the first blade holder about a first axis. The first and second retractor arms include respective second and third blades detachably secured thereto. The first and second retractor arms are transitionable between an approximated configuration and a spaced apart configuration. The second and third blades are configured to angulate about respective second and third axes that are defined by the respective first and second retractor arms.

Abstract: The invention relates to a system comprising: a view measurement device adapted to emit an ultrasound view signal and receive a reflected view signal; a view processing device adapted to detect, in the reflected view signal, a target view echo corresponding to an interface between first and second anatomical structures, to measure a flight time between the emission of an ultrasound view signal and the detection of the target view echo, and to represent an external surface of the first anatomical structure from the measured flight times.

Abstract: An instrument for inserting a spinal implant into an intervertebral space is disclosed. The instrument includes an elongated body having inner and outer shafts configured to longitudinally translate with respect to each other, a holding tip which is configured to articulate with respect to the elongated body in response to the longitudinal translation of the inner and outer shafts, and a driveshaft assembly configured to cooperate with the articulation of the holding tip and secure a spinal implant to the instrument. A spinal implant and a system for inserting a spinal implant into an intervertebral space including an insertion instrument and a spinal implant are also disclosed.

Abstract: A spinal spacer for engagement between vertebrae includes a body extending between a substantially contoured first end surface and a second end surface to define side surfaces and opposing top and bottom vertebral engaging surfaces substantially symmetrical about a centerline axis. At least one opening defines a hollow inner body and includes first and second intersecting openings extending through the top and bottom vertebral engaging surfaces. The second intersecting opening extends through the side surfaces. The second end surface includes at least one aperture formed therethrough in communication with the hollow inner body. A screw opening is defined through at least one plate insert configured to be removably coupled to the second end surface to substantially align the screw opening with the at least one aperture. The bone screw is configured to be threadingly secured within the at least one plate insert.

Abstract: The present invention provides a system and method of applying low dose, localized radiotherapy which is effective to reduce or eliminate the formation of post-operative scar tissue at surgical sites, such as an epidural site after spinal surgery. In an exemplary embodiment, a device is implantable before closing a surgical site as a barrier, the device being designed to deliver a desired therapeutic amount of energy to particular tissue. The device can be a barrier layer, seed containment unit, radiospike, or catheter. The energy may be provided by the material of the device itself, or may be provided by an external source, such as by circulating radioactive fluid through the device itself. Various embodiments include additional components of the device which deliver drug or chemical agents to targeted tissue and/or shield components to prevent dosage to non-targeted tissue.

Abstract: A method and system for providing private air travel to a plurality of customers includes establishing a pool of aircraft service providers and obtaining an aircraft service request from each customer. One or more aircraft that conform to each set of customer-specified parameters is selected from the pool of aircraft service providers and matched to the aircraft service request in a manner that minimizes the occurrence of passenger-less flights.
