Catheters with lubricious linings and methods for making and using them

Abstract

Coated devices for introduction into bodies and methods for making and using them are provided, such as delivery sheaths, guidewire lumen cores, and elongate leads. In one embodiment, a tubular device includes a proximal end, a distal end sized for introduction into a body lumen, and a lumen extending between the proximal and distal ends. The tubular device includes a relatively thin inner polyurethane liner including a coating on an inner surface thereof, e.g., providing a lubricious and/or hydrophilic lumen, and an outer layer surrounding the liner. In another embodiment, a lead is provided that includes a proximal end, a distal end, and at least one electrode on the distal end. A polyurethane cover surrounds at least a portion of an outer surface of the lead that include a coating, e.g., including a lubricious and/or hydrophilic material. Optionally, the cover may be removable from around the lead body.
