Abstract

A system for gaining access to an interventional site within vasculature through a vessel wall or other structure such as that of a medical device. An apparatus is provided to accomplish a sealed worksite as are sensor delivery systems including sealable sensor devices that are adapted to be placed at the interventional site.

Claims

1. A system comprising:

an elongate tubular member having a first lumen and a second lumen longitudinally enclosed therein, the first lumen configured to provide a vacuum through a valve associated with an inferior end into the first lumen formed within an annular interior of an outside wall of the elongate tubular member and the second lumen located axially interior to the first lumen and extending a total length of an inside of the elongate tubular member that is configured at a superior end to isolate a puncture in an exterior of a body cavity from the vacuum applied through the valve;

the elongate tubular member having a terminal end portion, associated with the superior end and delivered through the longitudinally enclosed second lumen, that is configured to engage the exterior of the body cavity from the interior and having a means for sealing the puncture in the exterior of the body cavity from the interior; and

an inner member coaxially received within the second lumen of the elongate tubular member along with the terminal end portion;

wherein the inner member comprises a wall puncturing assembly.

2. The system of claim 1, wherein the inner member further comprises a sensor delivery assembly.

3. The system of claim 2, wherein the sensor delivery assembly includes a sensor.

4. The system of claim 3, wherein the sensor includes a body and expandable structure attached to the body.

5. The system of claim 3, wherein the sensor includes a guide for advancing the sensor along a wire.

6. The system of claim 3, wherein the sensor delivery assembly includes a cannula that receives the sensor, the cannula having an internal bore which follows the contours of the sensor.

7. The system of claim 1, wherein the terminal end includes flexible walls providing an enlarged foot print and a sealing engagement when placed against the exterior of the body cavity.

8. The system of claim 1, wherein the wall puncturing assembly comprises a wall puncturing member.

9. The system of claim 8, wherein the puncturing member is retractable.

10. The system of claim 8, wherein the wall puncturing member is attached to and configured beyond a far end of the elongate tubular member.
