Devices and Methods for Modulating Medium Delivery

摘要

Devices, systems and methods for controlling, regulating, altering, transforming or otherwise modulating the delivery of a substance to a delivery site. The devices, systems and methods optimize the delivery of the substance to an intended site, such as a vessel, vascular bed, organ and/or other corporeal structures, while reducing inadvertent introduction or reflux substance to other vessels, vascular beds, organs, and/or other structures, including systemic introduction.

主权项

1. A system to control, regulate, alter, transform or otherwise modulate the fluid delivery of medium injected to a body site, comprising:
an injector for injecting the medium; a delivery catheter comprising a conduit for delivering the medium from outside of the body to a delivery site within the body; and a modulator disposed between the injector and the delivery catheter, the modulator comprising:
a medium reservoir, the reservoir including a chamber for receiving medium therein and at least one surface within the chamber capable of imparting a constant force on medium within the chamber; anda manifold having a manifold lumen therethrough, wherein the manifold lumen includes a first medium port fluidly coupled to the injector, a second medium port fluidly coupled to the chamber of the medium reservoir, and a third medium port fluidly coupled to the delivery catheter.
