Aneurysm sensing devices and delivery systems

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.

1 . A system comprising:
 an elongate member having a terminal end configured to be placed across a wall to an interior of a body cavity or medical device;   a first member configured to extend beyond an interior of a vessel wall; and   a second sealing member configured to engage an exterior of a vessel wall and the sensor attached to the first sealing member.   
     
     
         2 . The system of  claim 1 , further comprising a wall piercing member. 
     
     
         3 . The system of  claim 2 , wherein the piercing member is retractable. 
     
     
         4 . The system of  claim 2 , wherein the wall piercing member is attached to and configured beyond a far end of the first member. 
     
     
         5 . The system of  claim 1 , further comprising a sensor assembly attached to one of the first members and second sealing members. 
     
     
         6 . The system of  claim 1 , wherein the elongate tubular member is detachable from the first and second sealing members. 
     
     
         7 . The system of  claim 1 , wherein the first member includes a sealing assembly that engages the exterior of the wall. 
     
     
         8 . A system comprising:
 an elongate member having a terminal end configured to be placed across a wall to an interior of a body cavity or medical device; and   a sensor assembly having a first part configured to be placed within the vessel or medical device and a second part configured to be placed exterior the vessel or medical device.   
     
     
         9 . The system of  claim 8 , wherein the elongate member releasably receives the sensor assembly and includes a first cavity for the first part and a second cavity for the second part. 
     
     
         10 . The system of  claim 8 , wherein the sensor assembly includes a sealing member. 
     
     
         11 . The system of  claim 8 , wherein the terminal end of the elongate member is configured to pierce a wall. 
     
     
         12 . The system of  claim 8 , wherein the sensor assembly includes an expandable portion. 
     
     
         13 . The system of  claim 8 , wherein the sensor assembly includes a wall piercing member. 
     
     
         14 . The system of  claim 8 , wherein the sensor assembly includes a coil assembly.
