Abstract: A prosthetic leg apparatus for use with a user's stump, comprising: a socket, wherein the socket is constructed of a thermoplastic material; a pylon assembly, connected to the socket and adjustable in length; and, a foot portion, connected to the pylon assembly.

Abstract: The present invention provides a device for enhancing circulation by intermittently tightening and relaxing a closure encircling a limb. The device comprises a continuously operating motor, at least one rotating element and a mechanism driven by the motor for intermittently rotating the rotating element in a first direction to tighten the closure and in a second opposite direction to relax the closure, thereby applying a cyclic pressure on the limb.

Abstract: A guidewire stop is disclosed which can be positioned and frictionally locked to a bare guidewire at a user-defined location. The guidewire stop can be used to stop and/or lock a medical device, such as an embolic filter, at a treatment site inside a body lumen. The medical device may be attached to the guidewire stop.

Abstract: Quantification of the change in shape of the dicrotic notches of so-called distal pressure pulses acquired distal to a lesioned section of a lesioned blood vessel relative to the dicrotic notches of so-called proximal pressure pulses acquired proximal thereto enable determination of values of hemodynamic parameters. The envisaged hemodynamic parameters can include so-called Pulse Transmission Coefficients, non-hyperemic substitutes to the clinically accepted Fractional Flow Reserve and Coronary Flow Reserve indices, and a RC time constant indicative of the health of the vascular bed fed by a lesioned blood vessel.

Abstract: The present invention is directed toward determining a Coronary Flow Reserve (CFR) value for a stenosed blood vessel by way of pressure measurements acquisitioned proximal a stenosis in a stenosed blood vessel and distal thereto both at rest and at hyperemia in accordance with the relationship CFR &agr; (&Dgr;Phyper, &Dgr;Prest) where &Dgr;Phyper and &Dgr;Prest are the pressure gradients across the stenosis at rest and at hyperemia, respectively.

Abstract: The present invention relates to intravascular pressure measurement based devices and methods determining clinical parameters related to stenosis severity for improved clinical diagnosis and treatment of cardiovascular disease in blood vessels or tubular conduits. More specifically, the invention provides methods for the determination of the clinically significant well known Coronary Flow Reserve (CFR) parameter-previously acquired by velocity measurement devices. In addition Coronary Flow Reserve in the same vessel without stenosis may be estimated and uses to select the necessary medical treatment. Additional pressure based clinical parameters, Diastole to Systole Velocity Ratio (DSVR) and Fractional Flow Reserve (FFR) in stenotic blood vessel during intervention (using only pressure measurements across stenosis) may also be calculated simultaneously, with the same set of interventional devices. Correlation of CFR with these parameters (e.g.

Abstract: This invention relates to a method and devices for detection, localization and characterization of occlusions, aneurysms, wall characteristics and vascular bed. The invention is based on introducing an artificial pressure or flow excitation signal (a single signal or more) into the blood vessel (or in other tubular flowing fluid conduits), measurement and analysis of the pressure and or flow. The invention discloses a method and devices for detection and characterization of partial or total occlusion or aneurysm in blood vessels or in other tubular flowing fluid conduits within a body, such as urine flow in the urethra.
