Balloon catheter system for sealing puncture points in body cavities, hollow organs or in percutaneous systems in mammals

摘要

The present invention relates to a balloon catheter system for sealing puncture points or openings in body cavities, hollow organs or in percutaneous drainage operations in mammals, consisting of a filling catheter on the distal end of which a first balloon can be filled with the filling medium is arranged with a further balloon arranged proximally spaced apart therefrom. The balloons close the puncture point or the opening on the two sides in the filled state of the balloon. A hollow needle open at the shaft or the shaft end can be guided in the lumen of the filling catheter for filling the two balloons with the filling medium, wherein the shells of the two balloons enclose the shaft of the filling catheter. The filling catheter in each case has an opening arranged in the balloon lumen to fill the two balloons.

主权项

1. A balloon catheter system for sealing puncture points or openings in body cavities, hollow organs or in percutaneous drainage operations in mammals, comprising:
a filling catheter shaft configured for receiving a fluid medium having a proximal end and a distal end, said distal end having a first balloon having a first balloon lumen configured to be filled with the filling medium and a second balloon having a second balloon lumen configured to be filled with the filling medium, said second balloon arranged proximally spaced apart from said first balloon, whereby when said first balloon and said second balloon are inflated they are configured to close a puncture point or an opening by sealing said puncture point or opening on two sides, a hollow needle open at the shaft or shaft end and slidably engaged with a lumen of said filling catheter shaft whereby said hollow needle can be guided in the lumen of the filling catheter shaft, said hollow needle having a length sufficient to align said hollow needle opening with at least an opening for receiving said filling medium positioned within said first balloon, and an infusion catheter having a shaft with a distal end, at least said distal end passing through said first balloon and said second balloon, said filling catheter shaft positioned along an outer surface of said infusion catheter shaft thereby forming two independent and parallel lumens, said infusion catheter shaft having a distal end extending past said distal end of said filling catheter shaft and through said first balloon wherein when in use, said distal end is configured to project into puncture points or openings in body cavities, hollow organs or in percutaneous drainage operations in mammals, thereby providing or removing a fluid to or from a location distal from said first distal balloon and said second proximal balloon, wherein said first balloon and said second balloon enclose the filling catheter shaft and said infusion catheter, said second balloon having an opening sized and shaped to receive said filling medium, whereby, when the hollow needle is drawn back, the first balloon is filled with the filling medium prior to filling the spaced apart second balloon.
