Filed:

Sep 3, 2003

Appl. No.:

10/653812

Inventors:

Richard J Morrill - Billerica MA, US
John R. Fagan - Pepperell MA, US
David O. Williams - Barrington RI, US

Assignee:

Advanced Vascular Technologies LLC - Barrington RI

International Classification:

A61M 29/00

US Classification:

606200

Abstract:

An improved arterial catheter device for capturing emboli within the aorta and other arteries is described. The system typically includes an elongated catheter member bearing a filtration apparatus disposed at its the distal region, comprising a filter membrane and a mechanism for deploying and collapsing the filter. For reliable deployment, the deployment mechanism comprises at least one pair of struts, one being a compression strut and the other a tension strut. In use, the catheter is positioned so that the filter membrane is down stream from the possible embolic source and upstream from any vital organs of concern. When deployed the filter membrane will capture emboli from the blood stream, and upon filter removal will extract the emboli from the patient.

Assignee:

C. R. Bard, Inc. - Murray Hill NJ

International Classification:

A61M 2900

US Classification:

604 96

Abstract:

A balloon dilatation catheter adapted for use in percutaneous transluminal coronary angioplasty has an integral guidewire. The balloon and its supporting members are not attached to the guidewire at their distal ends. The supporting members are attached at their proximal ends to the guidewire. The guidewire has an increased freedom of rotational movement and the balloon and its supporting members do not adversely twist about the guidewire.

Appl. No.:

8/879569

Inventors:

John R. Fagan - Pepperell MA
Richard Choh - Lowell MA
Richard Morrill - Billerica MA

Assignee:

Medtronic AVE, Inc. - Santa Rosa CA

International Classification:

A61B 500

US Classification:

600585

Abstract:

An angioplasty guidewire includes a proximal shaft and an intermediate section extending from the shaft to a distal joint and having a stiffener and a flexible member. The stiffener and the flexible member are disposed in coaxial slidable relationship and operable, as the stiffener and flexible member undergo relative axial shifting, to cooperatively impart a variable stiffening force on the intermediate section. A flexible distal tip mounts to the end of the intermediate section and projects axially therefrom.

Appl. No.:

17/171529

- Irvine CA, US
Steven D. Cahalane - Pelham NH, US
Richard J. Morrill - North Billerica MA, US
John Alexander - Pinehurst NC, US

International Classification:

A61B 17/04

Abstract:

A first end of a wire is transluminally advanced to a location adjacent an atrium of a heart of a subject, while a second end of the wire remains disposed outside of the subject. From the location, the first end of the wire is penetrated through tissue into the atrium. A capture device is transluminally advanced into the atrium. Using the capture device, the first end of the wire is captured and pulled out of the subject. From the first end of the wire, a first anchor is tracked along the wire into the atrium, and is anchored to an annulus of a valve of the heart. A second anchor is advanced into the atrium, and is anchored to the annulus. Subsequently, the annulus is reshaped by applying tension between the first and second anchors.

International Classification:

A61F 2/24

Abstract:

A catheter system including a wire, a translatable catheter, and first and second tethers is introduced into a body of a subject. The translatable catheter has a curved portion proximate a distal end of the translatable catheter. The first tether is coupled to the wire, and passes proximally through the translatable catheter. The second tether is attached to the curved portion. The catheter system is positioned such that the wire is disposed at a first location in the body. While the wire remains at the first location, the translatable catheter is translated away from the wire by manipulating the first tether and the second tether. Other embodiments are also described.

Abstract:

The present teachings provide devices and methods of treating a tricuspid valve regurgitation. Specifically, one aspect of the present teachings provides devices and methods of identifying a suitable location on the tricuspid annulus, another aspect of the present teachings provides devices and methods of placing a wire across the tricuspid annulus at such an identified location, another aspect of the present teachings provides devices and methods of deploying a tissue anchor across such an identified location, and yet another aspect of the present teachings provides devices and methods of applying tension to two or more of such tissue anchors and reducing the circumference of the tricuspid annulus. As a result, a regurgitation jet is reduced or eliminated.
