US Patent:

7578831, Aug 25, 2009
Filed:

Jun 23, 2006
Appl. No.:

11/474111
Inventors:

Randolf von Oepen - Los Altos Hills CA, US
Lorcan Coffey - Tubingen, DE
Thomas Rieth - Hirrlingen, DE
Travis R. Yribarren - San Mateo CA, US
Arik Zucker - Zurich, CH
Assignee:

Abbott Laboratories - Abbott Park IL
International Classification:

A61M 29/00
US Classification:

606194
Abstract:

A catheter arrangement is described that is arranged to permit a guide wire or other structure to be fed laterally from the region of an expandable working element. The catheter includes an elongate flexible tubular member and an inflatable structure carried by a distal portion of the flexible tubular member. The flexible tubular member has a guide wire lumen and at least one fluid supply lumen that is in fluid communication with the inflatable structure. The inflatable structure includes at least one, and preferably two, inflatable members (which may take the form of balloons). In the case of two inflatable members, the first and second inflatable members are radially spaced about the guide wire lumen such that at least one gap is formed between the inflatable members. With this arrangement, the distal end of a guide wire may be advanced through the guide lumen and out of a side opening such that the guide wire passes laterally between the first and second inflatable members. With such an arrangement, a guide wire passing out of the side opening in the region between the inflatable members can readily be directed into a second branch of a vessel bifurcation while the device is positioned in a first branch.

US Classification:

204199, 204212, 204213, 2042861, 205640, 205686
Abstract:

An apparatus and method are provided for simultaneously electropolishing a plurality of metallic stents. A plurality of elongated members on the apparatus are movably engaged with a plate such that movement of the plate relative to the elongated members causes each of the elongated members to rotate on its respective longitudinal axis when immersed in an electrolytic solution. A continuous cathode is located in close proximity to each of the elongated members when they are immersed in the electrolytic solution.

604131, 600432
Abstract:

A system for delivering a contrast medium to a treatment site including a delivery device, and a portable power injector.

The portable power injector includes an injector body and is configured to contain a contrast medium. The injector body has a plunger disposed therein. The portable power injector also includes a pressure generator, the pressure generator being configured to apply a pressure to the plunger to drive the contrast medium from the injector body and through a distal end of the contrast injection lumen.

Assignee:

Abbott Laboratories - Abbott Park IL
International Classification:

A61M 29/00
US Classification:

606194, 604 9601, 60410305, 60410307
Abstract:

A dilatation balloon is fabricated according to a process that forms cavities and indentations in the balloon and/or catheter sections. A length of tubing is axially elongated and radially expanded in a form to provide the requisite biaxial orientation and strength. Then, an excimer laser or another type of laser or mechanical material removal tool is used to remove the polymeric material, virtually without thermal effects. Cavities in the sleeve sections of the balloon are defined and if desired, indentations in the cone sections are defined. Material removal, particularly near the balloon sleeves enables a thinner, more flexible bonding area between the catheter shaft and the balloon. Further, the indentations along the cone sections enables tighter wrapping of the balloon for a reduced delivery profile. Rigidity near the sleeves is reduced for better maneuverability of the catheter in tortuous passageways.

US Patent:

8048146, Nov 1, 2011
Filed:

Jun 30, 2006
Appl. No.:

11/479643
Inventors:

Eugene Young - Union City CA, US
Russ Borg - Campbell CA, US
David Trask - Redwood City CA, US
Travis Richard Yribarren - San Mateo CA, US
Erik Eli - San Mateo CA, US
Assignee:

Abbott Laboratories - Abbott Park IL
International Classification:

A61F 2/06
US Classification:

623 134, 623 115
Abstract:

Endoprosthesis, such as a stent, includes at least one annular element defined by a first set of strut members interconnected to define apices proximate opposite sides of the annular element. The annular element further includes a foot extension extending between at least one pair of circumferentially-adjacent strut members. The foot extension has first and second foot portions extending circumferentially from corresponding ends of the circumferentially-adjacent strut members, and are contoured to provide at least two areas of flexure. The first and second foot portions are joined at a toe portion of the foot extension, and define a circumferentially-directed apex between the pair of circumferentially-adjacent strut members. Preferably, at least one or more additional annular elements, each defined by interconnected strut members, are provided. The annular elements are generally expandable between a delivery configuration and a deployed configuration.

US Classification:

604 9601, 60416401, 604264, 604272, 604523, 604104
Abstract:

A catheter for delivering an agent to an injection site in a wall of a patient's body lumen, with an elongated shaft having a needle-through lumen slidably containing a needle therein, and an expandable member on the distal shaft section which has a collapsed configuration and a radially expanded configuration. In the radially expanded configuration, the expandable member supports the shaft in a position spaced away from the body lumen wall, and the needle slidably exits the needle-through lumen in the extended configuration through the port spaced away from the body lumen wall as a portion of the expandable member maintains the position of the port section of the shaft in the body lumen. The expandable member typically has an open-walled, helical, or lobed configuration providing a perfusion path along the expandable member.
