Filed:

Mar 20, 2002

Appl. No.:

10/102085

Inventors:

Benjamin David McDaniel - Newport Beach CA

Assignee:

Cordis Corporation - Miami Lakes FL

International Classification:

A61N 500

US Classification:

600 3, 600 7

Abstract:

A radioactive source ribbon assembly may be reusably utilized in conjunction with a delivery sheath or catheter for delivering therapeutic dosages of ionizing radiation to various anatomical regions. The radioactive source ribbon assembly comprises an outer jacket formed from or coated with a lubricious coating for insertion into the delivery sheath or catheter. The assembly also comprises a radiation resistant sleeve formed from a braided structure which encapsulates a radioactive source and core. The braided structure is the primary axial load bearing member of the assembly and functions as such without sacrificing assembly flexibility.

Appl. No.:

10/716822

Inventors:

Benjamin D. McDaniel - Corona Del Mar CA, US

Assignee:

Biosense Webster, Inc. - Miami Lakes FL

International Classification:

A61M 37/00

US Classification:

604 9501

Abstract:

An improved steerable catheter comprises an elongated tubular catheter body with a flexible tip section. A pair of slidably mated puller wires fixedly attached to each other at their distal ends extend from a handle at the proximal end of the catheter body through a lumen in the catheter body and into a lumen in the tip section. Proximal movement of one puller wire relative to the other results in deflection of the tip section.

Benjamin D. McDaniel - Corona del Mar CA, US

International Classification:

A61M 25/16

US Classification:

604533

Abstract:

A catheter grip adapted to couple with an introducer or sheath holds a catheter in position while in use in a patient's body. The grip has a hub defining a channel through which the catheter extends, a pair of grip members that work with each other to hold the catheter body between them, a pair of separators to release the catheter body, and a pair of tabs for the doctor to actuate the separators. Each pair of the grip members and the separators is situated on a different diameter of a surface that extends across the channel and each grip member and separator is diametrically opposed to its mate. Movement between the grip members and the separators is coordinated in that as the grip members move toward each other the separators move away from each other, and vice versa.

International Classification:

A61B 18/18

US Classification:

606 41, 606 49

Abstract:

A deflectable device, such as a catheter, is provided that includes a hinge that enhances the ability of the device to deflect or bend within a predetermined plane. The catheter comprises an elongated tubular catheter body having proximal and distal ends and at least one lumen extending therethrough. A distal segment is provided distal to the distal end of the catheter body. A tubular hinge is provided between the distal end of the catheter body and the proximal end of the distal segment. The hinge has an axis and at least one lumen extending therethrough. The tube includes at least one slot, and preferably a plurality of slots, extending part of the way through the hinge generally transverse to the axis of the hinge.

Appl. No.:

11/058102

Inventors:

Benjamin D. McDaniel - Irvine CA, US
Thomas V. Selkee - Claremont CA, US

Assignee:

Biosense Webster, Inc. - Diamond Bar CA

International Classification:

A61M 31/00

US Classification:

604 9504

Abstract:

An improved steerable catheter with in-plane deflection comprises a catheter body having proximal and distal ends and a lumen extending therethrough and a tip section at the distal end of the catheter body. The tip section comprises a flexible plastic tubing having a pair of diametrically-opposed lumens extending therethrough. The catheter also provides two puller wires manipulated through a control handle at the proximal end of the catheter body. Each puller wire extends through one of the pair of lumens in the tip section and through the lumen of the catheter body and is anchored to the control handle at its proximal end and anchored to the tip section at its distal end. The deflection mechanism is configured to generally define a plane along which deflection most readily occurs and an edge along which deflection is most readily avoided. The deflection mechanism extends longitudinally along a centerline of the tip section between the first and second puller wire and is configured generally with a cross section having a thinner dimension and a thicker dimension to bias the tip section to deflect in a plane parallel with the thinner dimension of the deflection mechanism and to resist deflection in a plane perpendicular to thicker dimension.

Assignee:

Biosense Webster, Inc. - Diamond Bar CA

International Classification:

A61B 18/14

US Classification:

606 41, 607101

Abstract:

A catheter has a three-dimensional, hollow ablation assembly that carries at least one ribbon electrode for circumferential ablation. In one embodiment, the assembly has a free-form framework that is constructed of multiple tensile members or wires that are interwoven such that the length of the framework increases while the circumference of the framework decreases, and vice versa. The assembly can also have a self-expanding stent-type framework which is mounted on the expander. In another alternative embodiment, the framework is a tubular or cylindrical structure whose side wall has longitudinal slots between longitudinal slats for radial expansion to a greater circumference when the length is decreased. The flexible ribbon electrode on the assembly is elastic, or is pleated so that it folds when the framework is collapsed and unfolds when the framework is deployed.

US Classification:

Abstract:

A method for treating tissue is provided. The method comprises introducing into a patient the distal end of a catheter. The catheter comprises a catheter shaft comprising an elongated tubing having proximal and distal ends, and a distal shaft comprising a tubing having proximal and distal ends. The distal shaft carries a treatment device along a side of the distal shaft. A hinge is mounted between the distal end of the catheter shaft and the proximal end of the distal shaft. The hinge enhances the ability of the distal shaft to bend relative to the catheter shaft in a single predetermined plane A force is exerted on the distal shaft to cause at least a portion of the treatment device that is along a side of the distal shaft to contact the tissue. The tissue is treated with the treatment device.
