Appl. No.:

12/757421

Inventors:

Hoang Phan - Fremont CA, US
John Lunsford - San Carlos CA, US
Fiona Sander - Los Altos Hills CA, US
Kevin To - Campbell CA, US
Michael Allen - Los Altos CA, US

Assignee:

XLumena, Inc. - Mountain View CA

International Classification:

A61B 1/01

US Classification:

600115

Abstract:

A guidewire has a guidewire body with a distal end and a proximal end. A balloon or other tissue anchor is disposed at or near the distal end of the guidewire, and the guidewire may be used to draw two layers of tissue into apposition by placing the guidewire through a tissue penetration, deploying the tissue anchor, and drawing proximally on the guidewire body. Optionally, the guidewire may include deployable blades for enlarging a tissue penetration as the guidewire is advanced therethrough.

Assignee:

XLumena, Inc. - Mountain View CA

International Classification:

A61M 5/00

US Classification:

604272

Abstract:

A trocar has an elongate body and a tissue-penetrating tip. One or more radially extending blade(s) are provided near the tissue-penetrating tip of the trocar body so that they automatically open as the trocar is advanced through tissue. The blades will enlarge the penetration which was formed by the tip of the trocar.

International Classification:

A61F 2/84

US Classification:

623 111

Abstract:

Transluminal access system includes a stent delivery catheter having a handle control mechanism. The catheter comprises a number of components for establishing an initial penetration between adjacent body lumens and subsequently implanting a stent or other luminal anchor therebetween. Manipulation of the stent components is achieved using control mechanisms on the handle while the handle is attached to an endoscope which provides access to a first body lumen.

International Classification:

A61F 7/12

US Classification:

607105

Abstract:

Devices, methods and systems for endovascular cooling of human or animal subjects are disclosed. A heat exchange catheter () having a heat exchanger () is attached to a source of a thermal exchange fluid () that circulates through the heat exchanger, thereby cooling the subject's flowing blood. This invention provides cooling devices, systems and methods for cooling the thermal exchange fluid more rapidly and/or to a lower temperature than was achieved by the prior art.

US Classification:

623 111, 606191, 606159

Abstract:

A catheter for penetrating and dilating a passage from a first body lumen to a second body lumen comprises a catheter body, a tapered dilating tip at a distal end of the catheter body, a reciprocatable needle carried in a central passage of the catheter body, a deployable anchor carried near a distal end of the needle, and an advanceable blade carried in a slot at the distal end of the catheter body and advanceable in a track formed axially along the needle. The catheter can be used to penetrate adjacent luminal walls by first advancing the needle, and advancing the dilator over the needle followed by deploying the anchor, applying proximal tension to hold the adjacent tissue layers together, and then advancing the dilator with the exposed blade to fully dilate the passage.

International Classification:

A61B 1/00
A61B 1/018

Abstract:

Described herein are devices for reversibly constraining an endoscope. Such devices may comprise: a base positionable proximate a patient; a column extending vertically from the base; an arm extending horizontally from the column; and a clamp coupled to the arm. In some embodiments, the clamp comprises a holder comprising an annular ring defining an endoscope receiving area or a first sidewall and a second sidewall together defining an endoscope receiving area. The holder is transitionable between a first configuration in which the annular ring or the first and second sidewall are configured to set apart from an endoscope in the endoscope receiving area and a second configuration in which the annular ring or the first and second sidewall are configured to clamp the endoscope in the endoscope receiving area.
