Patent ID: 8647311

Claim:
An infusion system which comprises: an elongated catheter formed with a central lumen extending between a proximal end and a distal end; a source of a fluid medium having particles suspended therein, wherein the source is connected in fluid communication with the proximal end of the catheter; a tip defining an axis and formed with a plurality of parallel lumens extending through the tip in an axial direction, wherein the tip is affixed to the distal end of the catheter to individually place each lumen of the tip in fluid communication between the central lumen and a vessel of a patient, and wherein each individual lumen is dimensioned to sequentially receive a portion of the fluid medium containing suspended particles therethrough, and wherein each lumen is sufficiently small to effectively separate the particles from clinging to each other as the particles are received into the lumen; and a device for moving the fluid medium with suspended particles through the lumen of the catheter, for further movement of the particles in alignment through individual lumens of the tip.
