SELF-CLEARING CATHETERS AND METHODS OF USE THEREOF

摘要

Methods and catheters suitable for removing or reducing the formation of cellular occlusion associated the catheters. The catheters include a surface coated or infused with magnetic nanoparticles. Once the catheter is implanted in a subject, the nanoparticles induce localized hyperthermia around the catheter in response to a magnetic field.

主权项

1. A self-clearing cannula for placement in a patient, comprising:
an elongated tube portion having an inner surface and an oppositely disposed outer surface, a first end fluidically connectable to a fluid source outside the patient and a second, oppositely disposed end for fluidically communicating with the patient; and a plurality of magnetic nanoparticles operationally connected to at least a portion of the cannula; wherein the metallic nanoparticles may be energized by an applied oscillating magnetic field to heat the cannula.
