Embodiment Construction

[0035] first reference figure 1 , which shows a system, generally designated 10, for introducing (infusing) fluids according to the present invention. As shown, the system 10 includes a catheter 12 that can be advanced into a vessel 14 to position the catheter 12 at a predetermined location (not shown) in the patient's vasculature. For the purposes of the present invention, vessel 14 is preferably an artery or vein in the patient's cardiovascular system, and system 10 is used for intraarterial, intravenous or intracoronary protocols.

[0036] Explain in detail, figure 1 System 10 is shown including a source 16 for holding a fluid medium 18 . also like figure 1 As shown in , a plurality of particles 20 are suspended in a fluid medium 18 to create a particle / fluid medium 22 . For the present invention, particles 20 may be some form of drug, or most likely, they will be some form of biologic (ie cells, genes or proteins). In any event, the particles 20 will be suspended in a...

Abstract

A system for moving particles suspended in a first fluid, and for infusing them into the stream of a second fluid, includes a catheter with a multi-lumen distal separator. The separator is formed with a plurality of parallel lumens, wherein each lumen has a predetermined diameter to reduce particle flocculation. An inflatable balloon, affixed to the outside of the catheter, can be provided to regulate flow of the second fluid and thereby facilitate entry of the particles into the stream of the second fluid. A reinforcing member is employed to strengthen the catheter wall under the inflatable balloon. With this arrangement, the catheter does not kink or collapse due to the pressure exerted on the catheter wall when the balloon is inflated. In one embodiment, the reinforcing member includes an annular shaped ring. In another embodiment, the separator is positioned under the balloon and acts as the reinforcing member.

Description

[0001] This application is a continuation-in-part of patent application No. 13 / 473,988, filed May 17, 2012, which is a continuation-in-part of patent application No. 12 / 563,876, the patent application No. .12 / 563,876 was filed on September 21, 2009, and both patent applications are currently pending. The contents of Patent Application No. 13 / 473,988 and Patent Application No. 12 / 563,876 are incorporated herein by reference. technical field [0002] The present invention generally relates to infusion systems for introducing particles into a fluid stream. More particularly, the present invention relates to infusion systems for introducing (infusing) particles of biological substances, such as stem cells, into the vasculature of a patient without diminishing the therapeutic effect of the biological substances. The invention is particularly, but not limited to, useful as a system using a multi-lumen filter that allows particles to enter the lumen of a separator individually or in...
