US Patent:

6669621, Dec 30, 2003

Filed:

Mar 14, 2001

Appl. No.:

09/805961

Inventors:

Michael Dennis OHara - Stewartsville NJ
Benjamin David McDaniel - Newport Beach CA

Assignee:

Cordis Corporation - Miami Lakes FL

International Classification:

A61M 3600

US Classification:

600 7, 600 1, 600 3, 600 8

Abstract:

A radioactive substance absorber is incorporated into an intravascular radiotherapy source ribbon assembly to prevent the migration of radioactive matter throughout the assembly container. The radioactive substance absorber comprises carbon in various forms and configurations. The radioactive substance absorber is positioned in proximity to the source core and absorbs radioactive materials which break free from the source core, thereby containing the radioactive material.

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.

Assignee:

Cordis Corporation - Miami Lakes FL

International Classification:

A61M 3600

US Classification:

600 8, 600 3, 600 4

Abstract:

A low attenuation radioactive seed utilizing a core having a fluted or non-circular cross section is utilized for increasing the dose rate, decreasing the dwell times and improving the clinical outcomes by increasing the dose consistency throughout the treatment zone. The fluted or non-circular cross section core would increase the surface area for the deposition of the radioactive substance thereby increasing the therapeutic efficacy of the seed. In addition, the fluted or non-circular cross section may be designed in a manner to reduce photon emission attenuation by reducing the distance an inwardly directed photon would have to travel to traverse the core.

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.

Appl. No.:

10/871677

Inventors:

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.

Assignee:

Biosence Webster, Inc. - Diamond Bar CA

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.

Assignee:

Biosense Webster, Inc. - Diamond Bar CA

International Classification:

A61M 5/32

US Classification:

604180

Abstract:

The present invention is directed to a catheter clamp that is affixable to a patient's skin to hold a catheter in position while in use within a patient's body. In one embodiment, the clamp has a base adapted to be removably adhered to the patient's skin, two clamp members supported on the base and defining a region therebetween to receive the catheter body, the clamp members being adapted to move between an open position and a closed position, and locking means for releasably locking said clamp members in said closed position to hold the catheter body in a generally fixed position relative to said clamp. In another embodiment, the clamp includes a base adapted to be removably adhered to the patient's skin, two clamp members supported on the base and defining a space therebetween to receive the catheter body, the clamp members being adapted to move between an open position and a closed position, and an elongated release tab extending between the two clamp members and configured to releasably lock the clamp member around the catheter body. The two clamp members may be pivotably coupled to each other and the tab may be pivotably attached on one of the clamp members.
