Abstract
A rotary coating apparatus and a method of coating medical devices, such as stents, is disclosed.
Claims17
An apparatus for coating a stent with a coating material, comprising a disk member having a surface that prevents or minimizes the ability of a coating material to adhere to the surface of the disk member, the disk member capable of rotating about an axis of the disk member, wherein a force caused by the rotation of the disk member causes the coating material applied to the surface of the disk member by a nozzle to discharge off of the disk member and onto a stent.
An apparatus for coating a stent with a coating material, comprising a disk member capable of rotating about an axis of the disk member, wherein a force caused by the rotation of the disk member causes the coating material applied to a surface of the disk member by a nozzle to discharge off of the disk member and onto stent, wherein the surface of the disk member on which the coating material is applied includes at least one groove for altering the path of the coating material on the surface of the disk member, the at least one groove being circular in form.
An apparatus for coating a stent with a coating material, comprising a disk member capable of rotating about an axis of the disk member, wherein a force caused by the rotation of the disk member causes the coating material applied to a surface of the disk member by a nozzle to discharge off of the disk member and onto a stent, wherein the surface of the disk member includes multiple grooves positioned concentrically to one another.
An apparatus for coating a stent with a coating material, comprising a disk member capable of rotating about an axis of the disk member, wherein a force caused by the rotation of the disk member causes the coating material applied to a surface of the disk member by a nozzle to discharge off of the disk member and onto a stent, wherein the surface of the disk member includes multiple grooves having a variable depths.
A apparatus for coating a stent with a coating material, comprising a disk member capable of rotating about an axis of the disk member, wherein a force caused by the rotation of the disk member causes the coating material applied to a surface of the disk member by a nozzle to discharge off of the disk member and onto a stent, wherein the surface of the disk member on which the coating material is applied includes a groove for altering the path of the coating material on the surface of the disk member, wherein the groove is spiral in form.
