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.
