US Patent:

20010049554, Dec 6, 2001

Filed:

Nov 18, 1998

Appl. No.:

09/195257

Inventors:

CARLOS E. RUIZ - PASADENA CA, US
ZVONIMIR KRAJCER - HOUSTON TX, US
GERALD DORROS - SCOTTSDALE AZ, US

International Classification:

A61F002/06

US Classification:

623/001440, 623/001350

Abstract:

The present invention provides a prosthesis formed from a plurality of tubular layers members deployed in vivo using endovascular techniques and material. The layers define a lumen through a diseased portion of a vascular system. Each layer may be constructed using overlapping tubular members to provide a custom prosthesis. Subsequent prosthesis layers overlapping in the central portion of the lumen strengthen the prosthesis walls and may incorporate biocompatible materials having desirable properties.

Appl. No.:

9/037590

Inventors:

Carlos Ruiz - Pasadena CA

International Classification:

A61M 3100

US Classification:

604500

Abstract:

Apparatus and methods for effecting controlled injury to a selected body region to induce muscular revascularization and to provide delivery of drugs and therapeutic agents. A transvascular or muscular revascularization device is provided comprising a stimulator with extended penetrating members and a depth regulator for controlling the extent of penetration through tissue membrane, an outer sheath for retention of the stimulator and selective deployment of the penetrating members of the stimulator, and energy transfer means in communication with the stimulator for effecting a controlled injury to a selected region with directed energy through the penetrating members of the stimulator. A method is further provided for effecting a controlled injury and drug delivery to selected blood vessels or muscle that includes selecting an elongated vascular probe and sheath assembly wherein the vascular probe is formed with a plurality of perforating members to penetrate a membrane wall and a sheath to retain the perforating members of the vascular probe in a retracted position. Upon introduction of the assembly into a selected region, the perforating members of the probe are deployed beyond the outer surface of the sheath to penetrate the selected region which provides localized drug delivery or a controlled injury.

Appl. No.:

8/990896

Inventors:

Carlos E. Ruiz - Pasadena CA

International Classification:

A61B 1704

US Classification:

606213

Abstract:

A hole closure device for use in medical applications, especially in treating cardiac septal defects, is provided that seals a hole by exerting pressure on an interior edge of the hole. The device includes a flexible tube that extends through a hole, and has an expansion ring disposed within it adjacent to the tissue on either side of the hole. The expansion rings, which have deployed diameters larger than that of the hole, cause the material of the tube in a mid-region of the tube to contact and conform to the interior edge of the hole. Methods for deploying the hole closure device to correct septal defects are also described.

Appl. No.:

8/959586

Inventors:

Carlos E. Ruiz - Pasadena CA

International Classification:

A61F 206

US Classification:

623 119

Abstract:

Apparatus and methods for regulating the flow of fluids through a body vessel or organ are provided by a stent comprising a deformable mesh covered with a biocompatible material, the mesh having a conical portion and a constricted region. The stent may be percutaneously and transluminally delivered and deployed in a vessel. The constricted region may then be selectively enlarged employing a conventional dilatation device to adjust the flow impedance created by the constricted region. In an alternative embodiment, the constricted region is preferably formed from a shape-memory material, so that the maximum degree of constriction may be recovered by heating the shape-memory material. Methods of implanting the stent and adjusting and optimizing the degree of flow impedance are also provided.

Inventors:

Carlos E. Ruiz - Pasadena CA

International Classification:

A61B 1700

US Classification:

606200

Abstract:

A removable vascular filter and apparatus and methods for removing the removable vascular filter are provided. The removable vascular filter is held in place by a coiled-sheet stent portion having a magnetic band disposed on its interior edge. A catheter system is also provided having an electromagnet configured to engage the magnetic band and enable the coiled-sheet stent portion and filter sack to be wound to a reduced diameter to facilitate transluminal removal of the vascular filter and its contents.

Appl. No.:

9/074568

Inventors:

Carlos E. Ruiz - Pasadena CA

International Classification:

A61M 2500

US Classification:

604284

Abstract:

An access system is provided comprising a main tubular member having one or more lateral openings and a branch segment or secondary tubular member configured to be disposed through the lateral openings. The main tubular member is positioned in a vessel so that the openings are aligned with branches of the vessel. A secondary tubular member, or one or more branch segments, are then extended through the openings and into the branches to provide access for the delivery of therapeutic devices. Methods of deploying the access system to treat bifurcated or multi-branched vessels are also provided.
