Abstract: The invention muscle fiber excitation system (MFES) targets improving muscular and skeletal systems and preventing blood clots. MFES consists of 2 shafts, each affixed with 2 CAMs featuring surround peaks and valleys surfaces, a platform with stiffener side and compliant other side, and 4 plungers at the corners. The shafts tied with timing bets through pulleys are driven with DC motor. As the CAMs rotate the peaks and valleys make contacts with the platform stiffener side causing the platform to telescope 1 mm to 4 mm displacements, transferring contact stress stimuli from platform stiffener to compliant human contact side at frequency that encompass muscle fiber excitation frequencies. Wearable and standing model tests show improved bone density, muscle contraction and blood flow, preventing blood pooling. There is no side effect compared to use of blood thinners for blood clot prevention. Wearable model is concealable compared to compression pneumatic device with user complaints.

Abstract: The present invention provides and a laser focused ablation apparatus and method of use configured to ablate a cement mantle surrounding a stem of a hip prosthesis, for use during a revision arthroplasty. The apparatus comprises a laser generation system generating a laser light and a handpiece to receive the laser light. The handpiece includes an elongated main conduit terminating at a laser emission tip, the laser emission tip providing a tip and a curvature disposed between the tip and the elongated main conduit such that the laser light exits the tip at a direction oblique to a longitudinal axis of the elongated main conduit.

Abstract: An improved socket for a prosthesis uses a liner material providing fluid flow through a porous matrix whose local pressure is adjusted by a control system communicating with multiple valves and pressure sensors. Control of pressure in a viscoelastic material provides an improved trade-off between comfort and stability.

Abstract: A vibrating footplate provides operates at two or more distinct vibration modes to provide improved stimulation to bone and muscle of a human body having multiple modes of resonance.

Abstract: An apparatus for and method of conducting a nerve conduction study is provided. In response to predetermined stimulation from an excitation device, a signal is generated that travels through a human body. The apparatus includes a sensing electrode operatively engagable with the human body downstream of the excitation device for sensing the signal. The apparatus further includes a pressure mounting structure operatively connected to the sensing electrode for controlling the pressure at which the sensing electrode engages the body. The pressure mounting structure includes a pressure source and a pressure sensor. A controller receives a pressure signal from the pressure sensor and the signal from the sensor electrode. The controller includes software to normalize the amplitude of the signal based on the pressure at which the sensing electrode engages the body.
