Abstract:
1. An apparatus for disrupting a clot over a luminal length of a blood vessel, the apparatus comprising: a catheter body comprising a proximal end and a distal end and having at least one lumen therethrough; an inner catheter shaft comprising a proximal end and a distal portion having at least one lumen configured for allowing passage of a wire or agitator, the distal portion of the inner catheter shaft having at least one port formed therein so as to permit fluid flow from the lumen of the inner catheter shaft, the inner catheter shaft being configured to slidably couple within the at least one lumen in the catheter body; a proximal isolation balloon disposed adjacent the distal end of the catheter body; a distal isolation balloon disposed adjacent a distal end of the inner catheter shaft; and an agitator that is rotatable and/or axially translatable for mechanical disruption of a clot in a blood vessel, the agitator comprising a non-linear region disposed in the inner catheter shaft lumen such that the at least one port is positioned along a distal portion of the non-linear region and the inner catheter shaft assumes the non-linear shape of the non-linear region of the agitator along a length of the non-linear region; wherein the position of the distal isolation balloon is adjustable relative to the proximal isolation balloon by axially extending and retracting the inner catheter shaft relative to the catheter body within the lumen of the catheter body.
