Abstract
A blood flow cessation device includes a catheter, an expandable member, and a rapid exchange port. The catheter includes a distal end portion and a proximal end portion. The expandable member is positioned at the distal end portion and is selectively expandable to stop blood flow through a vessel. The rapid exchange port is formed in the catheter at a location proximal of the expandable member. The rapid exchange port is configured receive a guidewire that passes through the distal end portion of the catheter to be positioned within the vessel.
Claims21
A blood flow cessation device, comprising:
- a catheter having a distal end portion and a proximal end portion;
- an expandable member positioned at the distal end portion and being selectively expandable to stop blood flow through a vessel;
- a rapid exchange port formed in the catheter at a location proximal of the expandable member, the rapid exchange port being configured to receive a guidewire that passes through the distal end portion of the catheter to be positioned within the vessel.
A blood flow cessation system, comprising:
- a blood flow cessation device comprising:
- a catheter having a distal end portion and a proximal end portion;
- an expandable member positioned at the distal end portion;
- a rapid exchange port formed in the catheter at a location proximal of the expandable member and distal of the proximal end portion;
- a treatment device;
- a guidewire extending through the rapid exchange port and through the distal end portion;
- wherein the blood flow cessation device is configured to advance along the guidewire through a vessel puncture and into a vessel where the expandable member is expandable to limit blood flow in the vessel, and the treatment device is configured to advance along the guidewire to the vessel puncture.
A method of treating a vessel having a vessel puncture, the method comprising:
- providing a blood flow cessation device, a guidewire, and a treatment device, the blood flow cessation device comprising a catheter having distal and proximal end portions, an expandable member, and a rapid exchange port positioned proximal of the expandable member and distal of the proximal end portion;
- advancing the guidewire through the vessel puncture and into the vessel;
- advancing the blood flow cessation device along the guidewire and into the vessel with the guidewire extending through the rapid exchange port;
- operating the expandable member to limit blood flow through the vessel;
- advancing the treatment device along the guidewire through the vessel puncture;
- treating the vessel with the treatment device.
