摘要:
Implants are used in combination with an anti-scarring agent in order to inhibit scarring that may otherwise occur when the implant is placed within an animal. The agent may be any suitable anti-scarring agent, e.g., a cell cycle inhibitor, and may be used in conjunction with a second pharmaceutical agent, e.g., an antibiotic. Suitable implants include intravascular implants, a vascular graft or wrap implant, an implant for hemodialysis access, an implant that provides an anastomotic connection, ventricular assist implant, a prosthetic heart valve implant, an inferior vena cava filter implant, a peritoneal dialysis catheter implant, a central nervous system shunt, an intraocular lens, an implant for glaucoma drainage, a penile implant, an endotracheal tube, a tracheostomy tube, a gastrointestinal device, and a spinal implant.
摘要:
One aspect of the invention relates to a graft, a surface of which is coated with an amphiphilic block copolymer that includes both hydrophobic and hydrophilic polymer chains. An amphiphilic block copolymer coating according to the invention can serve as a carrier for a very broad range of drugs, possibly including every drug presently used, being considered for use, or likely to be used in the future to inhibit stenosis. The release rates of the drugs can be controlled, for example, through the length of the polymer chains, through their ratio, or through the degree of cross-linking.
