Title:
CATHETER SYSTEMS HAVING FLOW RESTRICTORS
Document Type and Number:
WIPO Patent Application WO/2010/090858
Kind Code:
A3
Abstract:
Infusion catheter systems and methods are described herein that incorporate flow restrictors to balance flow to multiple target sites serviced by delivery catheters. Fluids may be delivered to the target sites using multiple separate delivery catheters or through multiple separate lumens located in the same delivery catheter. Flow balancing may be performed between multiple catheters that are fed from a single fluid source, between multiple separate lumens in a single delivery catheter that are also fed from a single fluid source. Multiple catheters may be fluidly connected to one or more flow restrictors housed within an anchor or in another embodiment, a catheter may be fluidly connected to a restrictor housed in one anchor and another catheter fluidly connected to a second anchor wherein each of the restrictors is also fluidly connected to a single fluid source. Two or more anchors may be fed from a single source, with each anchor containing one or more flow restrictors that feed one, two or more delivery catheters that are attached to each of the anchors (i.e., each anchor may be attached to one, two, three, or more delivery catheters).
