Method Of Delivering Embolic Particles To An Aneurysm
First Claim
Patent Images
1. A method of deploying embolic particles within a patient, comprising:
- inserting a delivery catheter having a proximal end portion and a distal end portion into the vasculature of a patient;
directing the distal end of the delivery catheter to a pre-selected site within the vasculature;
loading embolic particles into the delivery catheter;
applying hydraulic pressure to the embolic particles to move the embolic particles through the delivery catheter and out of the distal end of the delivery catheter into the pre-selected site;
monitoring a velocity of the embolic particles;
monitoring the hydraulic pressure being applied to the embolic particles; and
adjusting the hydraulic pressure to control the velocity of the embolic particles.

Abstract
A method of delivering embolic particles to an aneurysm includes inserting a delivery catheter into the vasculature of a patient and directing the distal end of the delivery catheter to a pre-selected deployment site. Embolic particles are loaded into the delivery catheter, and hydraulic pressure is applied to move the embolic particles through the delivery catheter. The hydraulic pressure is adjusted to control the velocity of the embolic particles and to reduce jetting.

11. A method of deploying expandable embolic particles within the vasculature of a patient, comprising:
-
inserting a delivery catheter having a proximal end portion and a distal end portion into the vasculature of a patient; directing the distal end of the catheter to a pre-selected site within the vasculature; loading a plurality of expandable embolic particles into an introducer having a proximal end portion and a distal end portion; attaching a fluid injector to the proximal end portion of the introducer; attaching the distal end of the introducer to the proximal end portion of the delivery catheter; applying hydraulic pressure to the embolic particles by injecting fluid from the fluid injector into the introducer so that the embolic particles move from the introducer into the delivery catheter and out of the distal end of the delivery catheter into the pre-selected site; monitoring a velocity of the embolic particles; monitoring the hydraulic pressure applied to the embolic particles; and adjusting the hydraulic pressure to control the velocity of the embolic particles. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
