A coating for a medical device is described. The coating comprises: a surface layer; and optionally a base layer; wherein the surface layer comprises a polymer chain attached to an anti-clotting group, wherein the anti-clotting group is selected from a sulfonic acid group, a sulfonamide group, a sulfamic acid group, a hydrogen sulfate group and a conjugate base thereof. Also described is a medical device comprising the coating, and uses and methods involving the coating and the medical device.

Novel, lubricious coatings for medical devices are disclosed. The coatings provide improved lubricity and durability and are readily applied in coating processes a low temperatures that do not deform the device. The present invention is also directed to a novel platinum catalyst for use in such coatings. The catalyst provides for rapid curing, while inhibiting cross-linking at ambient temperatures, thereby improving the production pot life of the coatings.

Treatment of palatal defects is accomplished through devices that have controlled start time. The devices expand directionally to provide appropriate levels of stress and strain to a target tissue to promote tissue growth over the course of days or weeks, even as the defect repairs itself.

Described herein is a method of coating a prosthetic device, such as an ocular prosthetic device, the method comprising nanoelectrospraying droplets comprising an active ingredient and/or a carrier species onto a surface of the prosthetic device in a predetermined pattern, the nanoelectrospraying involving controlling the flow rate of the droplets from a nozzle of the nanoelectrospraying equipment by controlling the voltage between the nozzle and the ocular prosthetic device. Also described herein are ocular prosthetic device formable according to the method.
