Method for deploying cuff prostheses

InactiveUS6110198AUnnecessary expansive forcePrevent radial movementStentsDiagnosticsModularityProsthesis
The present invention provides modular intraluminal tubular prostheses, particularly stents and stent-grafts, for the treatment of disease conditions, particularly aneurysms. Modular sections of the prostheses, or "prosthetic modules," may be selectively combined to form a composite prosthesis having characteristics which are tailored to the specific requirements of the patient. Each prosthetic module preferably includes one or more standard interface ends for engaging another module, the module / module interface typically comprising ends which overlap and / or lock within a predetermined axial range. Advantageously, the axial length, cross-section, perimeter, resilient expansive force, axial flexibility, liner permeability, liner extensibility, radial conformability, liner / tubal wall sealing and anchoring, and other prosthetic characteristics may be varied along the axis of the composite prosthesis, and also along the axis of each prosthetic module. The modules are preferably individually introduced into a lumen system of a patient body so that the composite prosthesis is assembled in situ. Ideally, selection of appropriate prosthetic modules and the flexibility of the interface overlap range provides a custom fit intraluminal prosthesis which provides a therapy tailored to the individual patient's needs.

Catheter for diagnostic imaging and therapeutic procedures

InactiveUS20070073271A1Reduced opening sizePreventing both recoil and whippingCatheterIntravenous devicesTreatments proceduresCatheter
A catheter for use in introducing fluid into a vessel or other bodily structure. The catheter comprises a stem and a restrictor. The stem has approximate a distal end thereof a porous section that defines microholes distributed thereabout, which are inclined by a predetermined angle in the proximal direction. Affixed to the stem, the restrictor includes a conically-shaped valve with an apex thereof defining an opening and pointing in the proximal direction. The opening generally decreases in size as the conically-shaped valve flattens out distally as the pressure of the fluid within the tip increases. The forces of the fluid flowing out of the opening of the restrictor and out of the microholes of the stem substantially balance thereby substantially eliminating both recoil and whipping of the catheter, thus enabling its position to remain exceptionally stable while the fluid is finely dispersed therefrom in a cloud-like form.

Planetary roller screw pair friction torque measurement device

The invention discloses a planetary roller screw pair friction torque measurement device. Friction torque measurement is realized by a base plate, a jack and a tension-compression sensor together. A planetary roller screw pair is loaded by a spring. The tilt angle of the base plate is adjusted by the jack to realize friction torque measurement. A support base is disposed on a guide rail, and slides front and back along the guide rail. The tension-compression sensor is installed between a nut and the support base, one end of the tension-compression sensor is connected with the support base, the other end is connected with the nut, and the tension-compression sensor is used to measure and calculate the comprehensive friction. When a screw rotates, the screw drives the nut to do linear motion, and the tension-compression sensor is connected with the nut and limits the rotation of the nut, and measures the size of friction. The spring is embedded into a retainer cup, and a thrust ball bearing is installed between the retainer cup and the nut, which can avoid the situation in which the spring and the nut directly contact each other to generate fiction to affect the final measurement result. The measurement device is simple in structure, highly universal, and safe and reliable.
