Abstract
Devices and methods for applying a polymeric coating to a medical device. The steps of the coating process including applying a liquid polymeric material to the surface of the medical device, then directing a stream of gas to impinge on the surface of the medical device. Excess liquid polymeric material is removed from the surface of the medical device. The devices used in the coating process and the coated medical device are also part of this invention.
Claims18
A method for applying a uniform polymeric coating to a medical device, the method comprising the steps of:
- providing a medical device having a plurality of surfaces including at least one internal surface;
- applying a polymeric coating to the plurality of surfaces of the medical device;
- and
- applying a stream of gas to the plurality of surfaces of the medical device, including the at least one internal surface, wherein the stream of gas is of a sufficient strength to remove excess polymeric coating.
A method for coating an implantable medical device, the method comprising the steps of:
- providing an implantable medical device having a plurality of surfaces, including at least one internal surface;
- coating a polymeric material over the plurality of surfaces of the implantable medical device;
- and
- applying a stream of gas to the coated surfaces of the implantable medical device, including the at least one internal surface, wherein the stream of gas is of sufficient strength to remove excess polymeric material from the coated surfaces of the implantable medical device.
In a process for applying a polymeric material to a medical device having a plurality of surfaces, including at least one internal surface, wherein a coating of polymeric material is applied over the plurality of surfaces of the medical device;
- the improvement comprising:
- applying a stream of gas to the coated plurality of surfaces of the medical device, including the at least one internal surface, wherein the stream of gas is of sufficient strength to remove excess polymeric material from the coated surfaces of the medical device.
