Abstract
An intravascular flow modifier and vascular reinforcement for treatment of aneurysms is formed of a single loop of wire formed into a series of transverse loops and longitudinal connecting sections to configure an essentially cylindrical reinforcement device that still allows, if desired, access to the neck of an aneurysm for insertion of embolic coils and the like.
Claims17
A method of manufacturing an intravascular flow modifier and reinforcement device for use in the treatment of aneurysms, comprising:
- forming a mandrel of heat resistant material into an essentially cylindrical shape representing the interior diameter of the device to be formed;
- inserting into said mandrel a series of pegs projecting from the surface of the mandrel and representing transition points between semi-circular loop portions of the device and longitudinal portions of the device;
- winding a wire about said pegs from a proximal position to a distal position and back to a proximal position to thereby form a device containing semi-circular loops and longitudinal portions and to form an essentially cylindrical configuration;
- and
- heat treating said device to a predetermined temperature to provide desired material characteristics.

A method of manufacture for a device to use as an intravascular flow modifier and aneurysm treatment comprising:
- forming an essentially cylindrical mandrel, the outside diameter of which represents the outside diameter of the device;
- forming grooves in the mandrel that are approximately the depth of the wire to be used in fabricating the device and which represent the pattern of semi-circular loops and longitudinal elements of the device;
- winding a wire element into the grooves to form the pattern of semicircular loops and longitudinal elements comprising the configuration of the device;
- and
- heat treating the wire to obtain a desired combination of resilience and flexibility.
