MEDICAL DRAINAGE DEVICES WITH CARBON-BASED STRUCTURES FOR INHIBITING GROWTH OF FIBROBLASTS
First Claim
1. A composition for use in manufacturing an implantable medical device, the composition comprising:
- a carbon scaffold comprising carbon fibers optionally combined with a biocompatible polymer; and
a layer of carbon nanotubes grown on the carbon fibers, the resulting structure forming a carbon fuzzy veil,wherein;
the carbon fuzzy veil resulting from the carbon nanotubes grown on the carbon scaffold is fibroblast-inhibiting relative to a carbon scaffold alone.

Abstract
Drainage devices for draining a fluid from a patient during treatment of a medical condition body are disclosed. The drainage devices comprise a body defining at least one conduit through the body from a distal end of the body to a proximal end of the body. The body comprises at least one carbon-based structure configured to inhibit growth of fibroblasts in the conduit when the fluid flows through the conduit. Example embodiments of the drainage device may include an ophthalmic shunt, a hydrocephalus shunt, an artificial mesh, an arteriovenous shunt, a thoracic catheter, and a central venous access device.
