Implantable scaffolds for treatment of sinusitis
This disclosure describes, inter alia, materials, devices, kits and methods that may be used to treat chronic sinusitis. Disclosed are biodegradable medical scaffolds for placement within sinus cavity of a patient, methods of making the implants and methods of treatment. The scaffolds comprise a structure having a substantially tubular configuration and a therapeutic-agent-containing layer.
1. A method of treatment of a human patient with chronic rhinosinusitis, comprising: a) providing a scaffold comprising i) a therapeutic-agent-containing layer comprising mometasone furoate and a biodegradable polymer material and ii) a therapeutic-agent-free polymer topcoat layer, said topcoat layer positioned on said therapeutic-agent-containing layer so as to slow the release of the mometasone furoate; b) delivering said scaffold to the middle meatus under conditions where the scaffold displaces the middle turbinate medially and delivers said mometasone furoate from the middle meatus to a sinus cavity of a human patient with chronic rhinosinusitis.
2. The method of claim 1 wherein the scaffold delivers said mometasone furoate to the ethmoid sinuses.
