Definitions
- the stent 11 comprises wire which has been formed into a serpentine shape having apices 15, which shape is helically wound into a tubular form
- the wire is preferably nitinol wire of, for example, about 0 23 mm diameter
- a preferred nitinol wire is wire of this diameter which has been 45% cold worked and electropolished, available from Nitinol Devices & Components Inc , Fremont, CA
- the stent is formed from a single length of wire for simplicity and lowest possible profile, the ends of the wire being terminated by attaching to an adjacent serpentine winding
- One method of forming the wire into the desired serpentine shape is to use a mandrel of similar diameter as the intended diameter of the desired tubular form of the stent The mandrel is provided with appropriately located pins which protrude radially from the exterior surface of the mandrel in locations corresponding to the intended locations of the apices of the serpentine shape A suitable length of the wire is then wrapped around
- Figure 4 is an end view of a stent of the present invention showing a stent 11 having raised apices 15R which extend inwardly into the lumen of the stent 1 1 and provide a filtering capability as a result of protruding into the passageway
- a stent 11 having raised apices 15R which extend inwardly into the lumen of the stent 1 1 and provide a filtering capability as a result of protruding into the passageway
- the device may also be useful blood vessel filters such as a vena cava filter
