International Classification:

A61B 600

US Classification:

600431

Abstract:

An apparatus and method enabling the injection of fluid media into a plurality of patients in which there is provided a fluid supply source providing multiple doses, metering means for measuring the doses, pressurizing means to effect injection, contamination preventing means between fluid source and patient and, when desired, electronic control means to integrate operation of the apparatus and process.

US Patent:

47248467, Feb 16, 1988

Filed:

Jan 10, 1986

Appl. No.:

6/817580

Inventors:

Russell M. Evans - Lower Burrell PA

Assignee:

Medrad, Inc. - Pittsburgh PA

International Classification:

A61B 500
A61M 2500

US Classification:

128772

Abstract:

A catheter guide wire assembly for use in angioplasty. The assembly has a combined core and safety wire extending longitudinally between its proximal and distal ends. A wound wire is positioned around the combined core and safety wire and follows the contour thereof. The combined core and safety wire has a relatively short and relatively flexible distal end portion with a first diameter, an elongated, relatively rigid proximal body portion having a diameter greater than the first diameter, and a tapered intermediate portion interconnecting the distal end portion and the proximal body portion. Ends of the wire and the combined core and safety wire are rigidly connected to each other. The guide wire assembly guides and supports a balloon catheter used to dilate a stenosis region of a blood vessel. Since the distal end has a reduced diameter, the distal end can be left within the stenosis region during the performance of a fluoroscopic process used to ascertain whether or not the stenosis region has been adequately enlarged by a dilatation procedure.

Assignee:

Medrad, Inc. - Pittsburgh PA

International Classification:

A61B 500

US Classification:

128772

Abstract:

A core wire insertable in a catheter guide wire assembly provides a defined degree of rigidity to the catheter assembly to allow the assembly to be maneuvered through the tortuous path of the vascular or other system of a patient. The core wire includes, at its distal end, a paddle having a substantially barrel-shaped body, leading to a continuous chamfer which terminates in a truncated end. Further, the core wire can have a curved section adjacent its distal end. The curved section is made by press hardening the generally circular core wire into a substantially rectangular shape such that the press hardened wire memorizes the arc of curvature. When the core wire is press hardened into a rectangular shape, a singular degree of freedom of movement is imparted to the wire in contrast to the two degrees of freedom of movement of the cross-sectionally circular core wire. A method of manufacture is also described using concave/convex mating dies or flat plate dies.
