Filed:

Apr 27, 2009

Appl. No.:

12/430403

Inventors:

Elizabeth A. Eaton - Bloomington IN, US

Assignee:

Cook Incorporated - Bloomington IN

International Classification:

A61F 2/01

US Classification:

606200

Abstract:

An embolic protection device for capturing emboli during treatment of a lesion in a blood vessel is presented. This embolic protection device generally comprises a plurality of struts having a predetermined shape and being configured to move between an expanded state for engagement with the blood vessel and a collapsed state for filter retrieval and delivery and a filter portion circumferentially attached to the struts having a proximal end and a distal end; the filter portion extending freely from the proximal end to a closed distal end. The filter portion forms at least one annulus chamber in the expanded state with the closed distal end of each chamber being not coincident to the center longitudinal axis of the blood vessel in order capture emboli in the chambers and to reduce any overall restriction of blood flow through the filter portion.

Appl. No.:

Inventors:

ELIZABETH A. EATON - Bloomington IN, US

Assignee:

Cook Incorporated - Bloomington IN

International Classification:

A61B 17/22

US Classification:

606159

Abstract:

A circumferentially and longitudinally continuous scoring structure having a diameter in an initial unrestrained state that is smaller than a deflated diameter of the balloon is disposed around an outer surface of the balloon in an expanded configuration. The scoring structure continually exerts a radially inward compressive force against the balloon such that when the balloon is expanded from a deflated configuration to an inflated configuration, the scoring structure expands in a radially outward direction and remains in continuous compressive contact with at least a portion of the balloon as the balloon unfolds. The scoring structure may be entirely free of attachment to the balloon and catheter, and may extend substantially a length of a working region of the balloon. The scoring structure may include a plurality of circumferentially compressible members connecting longitudinal members.

Cook Incorporated - Bloomington IN

International Classification:

A61M 25/09
B29C 65/02

US Classification:

604528, 156157, 156 86

Abstract:

A medical catheter device is disclosed that comprises a tubular shaft member, a soft tip member, and a wire guide lumen extending longitudinally within the tubular shaft member and the soft tip member. The wire guide lumen is offset relative to the centerline within the soft tip member. By offsetting the inner diameter of the soft tip member in such a way as to not change the outward profile of the catheter, the soft tip will have improved tracking across existing stents and eccentric lesions.

International Classification:

A61M 25/10
A61B 6/00

US Classification:

600435, 60410102, 604509

Abstract:

Catheter balloons () for delivering a bioactive () to a body vessel in a greater amount and/or more quickly are provided, as well as related methods of treatment. The catheter balloon may include a dual balloon assembly at the distal portion () of the catheter having an inner balloon (), an outer balloon () with apertures () concentrically arrayed around the inner balloon, and a catheter shaft () adapted to deliver a carrier () through the apertures of the outer balloon. The bioactive is disposed on a portion of at least one of the inner and outer balloon surfaces. Radial outward expansion of the inner balloon urges the outer balloon into contact with the wall of the body vessel. The carrier is introducible within the catheter shaft to pass through the annular lumen () between the balloons and through the apertures of the outer balloon. The carrier interacts with the bioactive in order to release a therapeutically effective amount of drug to the wall of the body vessel.

International Classification:

A61M 25/09
A61M 25/00

Abstract:

The disclosure is directed to a targeting guidewire. The guidewire includes a distal portion including four portions and three transition zones between the adjacent portions. A first and a third portions have a smaller stiffness than a second and a fourth portions. The first and the third portions may also have a smaller overall outer diameters than the second and the fourth portions. The three transition zones comprises marking elements so as to delineate their locations.

International Classification:

A61F 2/958

A61F 2/954

Abstract:

A stent delivery balloon catheter assembly includes a catheter that defines exactly one or two lumens, which includes an inflation lumen that extends from an inflation port at a proximal end to open through a distal end of the catheter. The catheter defines a wire guide channel that terminates at a wire guide exit located a distance from the distal end of the catheter. A balloon with a closed distal end is attached to the catheter distally of the wire guide exit, and extends distally beyond the distal end of the catheter. The balloon is in fluid communication with the inflation lumen. A column strength stiffener has a proximal end attached to the catheter distally of the wire guide exit, and has a balloon support segment extending distally away from the distal end of the catheter within the balloon. A distal end of the column strength stiffener is attached to the closed distal end of the balloon

International Classification:

A61M 25/10
A61M 25/00

Abstract:

A system for providing lumen support and dilation includes a balloon catheter having an inner balloon and an outer mesh bonded to the shaft, with the mesh surrounding the inner balloon and defining an intermediate space therebetween. The mesh may have holes formed in an outer wall, with the inner balloon being free from holes. The shaft includes a delivery lumen in communication with the intermediate space. Daughter balloons are deliverable into the intermediate space through the delivery lumen and into engagement with holes formed in the mesh, where the daughter balloons are inflated and retained by the holes of the mesh. The catheter may include one or more preloaded wires extending through the delivery lumen and into the intermediate space and through the holes, such that the daughter balloons are deliverable over the wires into the corresponding hole.

International Classification:

A61M 25/10

Abstract:

A system for providing dilation and support to a body vessel includes a shaft having two compliant balloons attached to the shaft and spaced apart longitudinally from each and defining a longitudinal intermediate space between them. The shaft includes an inflation lumen for inflating the balloons and a delivery lumen for delivering secondary balloons into the intermediate space. The shaft includes side-ports that provide communication from the delivery lumen. Secondary balloons are deliverable over wires that extend through the delivery lumen and out of the side-ports, with the secondary balloons delivered through the side ports and to a desired location and inflated in the intermediate space or adjacent the intermediate space, such as to branch vessels. The compliant balloons are inflatable toward each other to take up the intermediate and conform to the shape of the body vessel and the secondary balloons.
