Abstract
An occlusion device for sealing a puncture through tissue includes a tubular wire member having a proximal end, a distal end sized for insertion into the puncture, a lumen extending between the proximal and distal ends, a port adjacent the proximal end communicating with the lumen, and a balloon on the distal end. A source of fluid is connectable to the wire member for delivering fluid via the port into the lumen for expanding the balloon. A piston is movable axially within the wire member to allow fluid to be delivered into the lumen, to isolate the lumen, and to deliver fluid within the lumen into the balloon to expand the balloon.
Claims20
An occlusion device for sealing a puncture through tissue, comprising:
- an elongate tubular member comprising a proximal end, a distal end sized for insertion into a puncture, a lumen extending at least partially between the proximal and distal ends, and an expandable occlusion element carried on a distal region of the tubular member, the occlusion element having an interior communicating with a distal opening in the lumen;
- and
- an elongate piston member movable within the lumen of the tubular member for delivering fluid into, and drawing fluid out of, the interior of the occlusion element to thereby expand and collapse the occlusion element, the piston member having a proximal end extending from a proximal opening of the tubular member lumen.
An apparatus for sealing a puncture extending through tissue from a patient's skin to a body lumen, comprising:
- a delivery sheath comprising a proximal end, a distal end sized for insertion into the puncture, and a lumen extending between the proximal and distal ends;
- an elongate tubular member comprising a proximal end, a distal end insertable through the delivery sheath lumen, a lumen extending at least partially between the tubular member proximal and distal ends, and an expandable occlusion element carried on a distal region of the tubular member, the occlusion element having an interior communicating with a distal opening in the tubular member lumen;
- and
- a piston member movable within the tubular member lumen for delivering fluid into the interior of the occlusion element for expanding the occlusion element, the piston member having a proximal end extending proximally from the tubular member lumen and sized to pass through the delivery sheath lumen.
A method for sealing a puncture extending through tissue from a patient's skin to a body lumen, comprising:
- introducing a distal end of an elongate occlusion member into the puncture until an expandable member carried on the distal end is disposed within the body lumen, the occlusion member comprising a lumen communicating with an interior of the expandable member;
- advancing a piston distally within the occlusion member to deliver fluid located in the occlusion member lumen into the interior of the expandable member to thereby expand the expandable member;
- retracting the occlusion member at least partially from the puncture to cause the expandable member to substantially seal the body lumen from the puncture;
- advancing a sheath over the occlusion member into the puncture;
- and
- delivering sealing compound into the puncture through the sheath.
