摘要:
An implantable medical device (e.g. a vascular filter for use in a blood vessel or vein), and a method of forming thereof, comprises providing a plurality of struts 22 each having a first and second end with an operative length 32 there between. Each strut includes a strut skeleton (34, Fig 3) having a first flexural modulus and a biodegradable reinforcement element (36, Fig 3) which extends along the operative length 32 attached to the strut skeleton; the reinforcement element and the strut skeleton together having a second flexural modulus greater than the first flexural modulus. The reinforcement element and/or the strut skeleton varies in at least one of amount and composition continuously along the operative length such that the second flexural modulus also varies in a continuous manner along the operative length. As the reinforcement element degrades the flexural modulus of the strut changes from the second flexural modulus to the first flexural modulus.
