Marked fluoropolymer surfaces and method of manufacturing same

摘要

A method of manufacturing a coated low-friction medical device, such as low-friction medical tubing, including applying a coating to one or more selected portions of a surface of low-friction medical tubing to indicate at least one marking formed along the surface of the low-friction medical tubing, and simultaneously or substantially simultaneously: (a) curing the applied coating to a designated temperature (which is above the temperature at which the low-friction medical tubing begins to decompose and shrink) to adhere the applied coating to the surface of the low-friction medical tubing, (b) utilizing one or more anti-shrinking devices to counteract or otherwise inhibit the shrinking of the low-friction medical tubing, and (c) exhausting any harmful byproducts resulting from curing the low-friction medical tubing to a temperate above the temperature at which the low-friction medical tubing begins to decompose.

主权项

1. A method of manufacturing a coated polytetrafluoroethylene tube, said method comprising:
(a) blocking a portion of an outer surface of a body of a polytetrafluoroethylene tube; (b) applying a coating to a first unblocked portion of the outer surface of the body of the polytetrafluoroethylene tube, said coating including:
(i) a first pigment of a first color, and(ii) a binder; (c) partially curing said coating; (d) after partially curing said coating, employing at least one anti-shrinking device to inhibit at least a portion of the body of the polytetrafluoroethylene tube from shrinking during a further cure; and (e) after employing the at least one anti-shrinking device, further curing said coating to cause the coating to bond to the outer surface of the body of the polytetrafluoroethylene tube to indicate at least one marking formed along the outer surface of the body of the polytetrafluoroethylene tube.
