Abstract
A vascular occlusion, flow restriction, shunt or filter device is disclosed comprising the assembly of at least two, of a number of selectable discrete interconnectable, interchangeable components, at least one component being of the type fabricated from metal strands braided into a tubular metal fabric having an expanded preset configuration and an elongated, collapsed reduced diameter configuration for delivery through a catheter to a treatment site and the device shaped to create an occlusion, flow restriction or shunt when placed in an opening in a body organ or vessel, the woven metal fabric having a memory property whereby the medical device tends to return to the expanded preset configuration when unconstrained.
Claims14
A method of producing a collapsible medical device comprising:
- providing a plurality of discrete interconnectable components each having two ends, at least one of the components comprising a plurality of metal strands woven into a tubular metal fabric having a proximal end and a distal end, the tubular metal fabric having an expanded preset configuration;
- securing at least one end of the tubular metal fabric thereby gathering and inhibiting unraveling of the strands;
- providing a connector attached to each end of each component for connecting multiple components to one another or to a delivery system in a reversible manner, wherein each connector has the same configuration;
- and
- assembling the medical device by connecting selected components together in a desired sequence.
