A method of forming a silicone coating on an electrode carrier for use in cochlear implant systems includes dissolving silicone and dexamethasone in a solvent to form a solution, adding a non-solvent to the solvent, the non-solvent miscible with the silicone and the dexamethasone having a solubility in the non-solvent of below about 5 mg/ml, and curing the solution to form the silicone coating on the electrode carrier.

This disclosure describes, inter alia, materials, devices, kits and methods that may be used to treat chronic sinusitis.

Adult autologous stem cells cultured on a porous, three-dimensional tissue scaffold-implant for bone regeneration by the use of a hyaluronan and/or dexamethasone to accelerate bone healing alone or in combination with recombinant growth factors or transfected osteogenic genes. The scaffold-implant may be machined into a custom-shaped three-dimensional cell culture system for support of cell growth, reservoir for peptides, recombinant growth factors, cytokines and antineoplastic drugs in the presence of a hyaluronan and/or dexamethasone alone or in combination with growth factors or transfected osteogenic genes, to be assembled ex vivo in a tissue incubator for implantation into bone tissue.

Described here are devices, systems, and methods for treating conditions or diseases of the nose, ear, or throat with an expandable device having a drug coating. The expandable devices may be delivered to a body cavity in a low-profile configuration and expanded to contact surrounding tissue. The expandable devices may deliver or release the drug coating to the tissue. Multiple expansions of a single device may be employed during treatment. Various coating excipients and manufacturing parameters for the expandable devices may also be adjusted to enhance or slow transfer of the drug coating and/or release of the drug to the target tissue site. The drug transferred to the tissue may act as an in situ depot that enables maintenance of a therapeutic level of locally delivered drug for a desired time period after removal of the expandable devices.

Provided is a slow release composition to promote bone growth, the slow release composition comprising: an oxysterol encapsulated in a biodegradable polymer to control the release of the oxysterol. Methods of making and use are further provided.

Compositions including a surface or film comprising nanofibers, nanotubes or microwells comprising a bioactive agent for elution to the surrounding tissue upon placement of the composition in a subject are disclosed. The compositions are useful in medical implants and methods of treating a patient in need of an implant, including orthopedic implants, dental implants, cardiovascular implants, neurological implants, neurovascular implants, gastrointestinal implants, muscular implants, and ocular implants.

Provided herein are devices and methods for treating inflammation and pain of articular joints (e.g., the knee). An implantable device includes an elongate body extending from a proximal end to a distal end, a flange disposed at the proximal end, a bore extending from an opening at the proximal end into the elongate body, one or more fixation members disposed on an outer surface of the elongate body, and a payload (e.g., a drug-polymer core) having a therapeutic agent disposed within the bore. The payload has a substantially constant surface area on an exposed portion throughout elution of the therapeutic agent after the implantable device is implanted in a body. The therapeutic agent is configured to elute using zero-order kinetics, constantly and continuously at an amount that is above a predetermined lower threshold and does not exceed a predetermined upper threshold unlike a pulse-dose injection.

Various embodiments of the present invention include a cannula coated or compounded with a material to extend the wear time for a patient by reducing inflammation and therefore increasing the time that the cannula may remain inserted, thereby increasing the effectiveness of the drug delivered using the cannula. The material may include a hydrophilic material, an anti-microbial material, an anti-inflammatory material, anti-thrombogenic material, or a combination of any of these materials.

Provided is a slow release composition to promote bone growth, the slow release composition comprising: an oxysterol encapsulated in a biodegradable polymer to control the release of the oxysterol. Methods of making and use are further provided.

An intracardiac system has an intracardiac pacemaker and a cover. The cover at least partially surrounds the pacemaker. An inner surface of the cover, which faces the pacemaker, includes an inner layer with bioresorbable material. There are also described methods for implanting and explanting an intracardiac pacemaker.
