International Classification:

A61B 5/00
A61B 5/05

US Classification:

600347, 600365, 600345

Abstract:

Disclosed herein are systems and methods for a continuous analyte sensor, such as a continuous glucose sensor. One such system utilizes first and second working electrodes to measure additional analyte or non-analyte related signal. Such measurements may provide a background and/or sensitivity measurement(s) for use in processing sensor data and may be used to trigger events such as digital filtering of data or suspending display of data.

Appl. No.:

11/464036

Inventors:

Matthew Rust - Santa Rosa CA, US
Prema Ganesan - San Francisco CA, US
Curtis Hanson - San Diego CA, US
Jack Chu - Santa Rosa CA, US

Assignee:

Medtronic Vascular, Inc. - Santa Rosa CA

International Classification:

A61B 17/08

US Classification:

606153, 623 135

Abstract:

The invention provides a method of providing an endovascular bypass. The method includes the steps of inserting an elastic needle carrying a guidewire adjacent an ostium via a catheter and extending the needle through a branch vessel wall. The method continues by extending the needle through the extravascular space and inserting the needle through a main vessel wall to create an opening. The needle is retracted, leaving the guidewire in place. A bypass stent graft is inserted along the guidewire to provide a pathway between the branch vessel and the main vessel, and the inserted bypass stent graft is expanded. The branch vessel is occluded between the ostium of the bypass stent graft and the main vessel, and a main stent graft is inserted in the main vessel proximate the opening in the main vessel wall.

International Classification:

A61F 2/84

US Classification:

623 111, 606108, 623 115, 623 123

Abstract:

A braided flange branch graft formed of a braided super elastic memory material includes a neck between an inner flange and an outer flange. The neck is positioned in a side opening in a sidewall of a main stent graft and the inner flange and outer flange are deployed on opposite sides of the sidewall. The inner flange and the outer flange have a diameter greater than a diameter of the side opening in the sidewall of the main stent graft. Thus, the sidewall of the main stent graft is sandwiched between the inner flange and the outer flange securely and simply mounting the braided flange branch graft to the main stent graft. The braided flange has a substantially unobstructed fluid communication passage therethrough. Further, when stretched into a substantially cylindrical shape for delivery, the braided flange branch graft has a small delivery profile and is extremely flexible.

Assignee:

Medtronic Vascular, Inc. - Santa Rosa CA

International Classification:

A61F 2/06

US Classification:

623001350

Abstract:

A stent graft extends in a flow lumen to span a defective portion of the flow lumen and seal the defective portion from further blood contact. The stent graft includes a pair of apertures, from which extensions project into the renal arteries to seal the passage of blood into the renal arteries from the abnormality. The apertures are larger than the opening of the renal arteries, such that the apertures need not be centered with the renal arteries to enable placement of the extensions. The aperture opening and side branch extensions contain hook and loop structures to provide a variably positionable seal of the aperture opening.
