Coatings for medical devices having selectable levels of durability and lubricity are disclosed. The coatings include polymeric material components, the characteristics and relative amounts of which can be selected to provide target levels of durability and lubricity. Methods of making the coatings for medical devices are also disclosed.

An angioplasty balloon (1) comprises an elongate tube (16) having a relaxed delivery configuration and an expanded deployed configuration. The elongate tube (16) comprises a proximal neck portion (10), a distal neck portion (8), a main body region, a tapered proximal portion (11) extending between the main body region and the proximal neck portion (10); and a tapered distal portion (9) extending between the main body region (3) and the distal neck portion (8), the elongate tube has only three fins (4, 5, 6) which are integrally formed with the tube and which are spaced equidistant from one another about the exterior of the tube. The fins (4, 5, 6) project radially outwardly from the exterior surface of the tube and the fins (4, 5, 6) extending longitudinally only along part of the main body region (3), resulting in the end-sections of the balloon main body being fin-free.

Abrégé

A delivery system includes a catheter, and a drug coated angioplasty balloon mounted on the catheter. The balloon has a wrapped or folded delivery configuration and an expanded deployed configuration. A protective sleeve surrounds the drug coated balloon in the delivery configuration to minimise wash-off of drug from the balloon during delivery. The protective sleeve is retractable, so that once the drug coated balloon is at or near the treatment site, the sleeve can be retracted to allow the drug coated balloon to operate effectively. The protective sleeve can have a spacer mounted to or integral with the protective sleeve. The spacer in one case can comprise of interior ribs or ridges on the sleeve which minimise the surface area of the sleeve in direct contact with the drug coating on the balloon.

Abrégé

A medical device delivery system provides for a two-stage withdrawal of a deflated balloon portion of a catheter and the remains of a ruptured sheath. The deflated balloon portion is withdrawn from within an expanded medical device a predetermined distance before the remains of the ruptured sheath begins being removed from between the expanded device and a vessel wall. Initiating removal of the deflated balloon portion before the sheath reduces a total amount of drag that is exerted against a self-expanding medical device that has been deployed in a vessel.
