Abstract
Apparatus and methods are provided for treating pseudoaneurysms using freeze-dried hydrogel particles that expand and/or absorb fluid within a pseudoaneurysm. An apparatus includes an elongate tubular member including a proximal end, a distal end sized for introduction through tissue into a pseudoaneurysm or other body cavity, and a lumen communicating with an outlet on the distal end. The particles are provided within the lumen and dischargeable through the outlet, e.g., using a plunger or other actuator. The apparatus may include one or more of a bled-back channel, flow sensor, pressure sensor, and markers for monitoring the distal end during introduction into the pseudoaneurysm.
