<p>A medical device (100) or intravascular device, and methods of use. The devices may be tubular and may have a flexible polymer tip (120). The body (105) may be nitinol and may have cuts part (110) way through along its length to facilitate bending. The device (100) may have a liner (203) which may extend through the tip or form the tip. The device (100) may have markers (122, 123) readily visible on an X-ray viewer during insertion. The tip (120) may have an anti-collapsing (1032, 1333) structure and may be shaped before use to perform a medical procedure such as treating an aneurysm. The device (100) may have a strong fiber (840) through it for complete removal. The method may include selecting the device, bending the tip, setting the shape, and inserting the device into the patient's anatomy. The shape of the tip may be set by heating with steam (1848) and then removing a mandrel (1840).</p> |
