Medical device having a constricted region for occluding fluid flow in a body lumen

A medical device adapted for implantation into a body lumen, including:

• a radially self-expandable support structure having first and second opposite ends and including a plurality of elongate structural filaments that are interwoven, the support structure expandable from a reduced-diameter compressed state to a self-supporting and lumen-engaging expanded state;
• and
• flexible fluid flow-occluding membrane including polymeric filaments interwoven with the structural filaments and expandable with the support structure from a reduced-diameter compressed state to an expanded state for occluding fluid flow through the body lumen when the support structure is in the lumen-engaging expanded state, the membrane comprising:
• a first tubular end coextensive with at least a portion of the length of the support structure;
• and
• a constricted region extending from the tubular end beyond the second end of the support structure.

A medical device adapted for implantation into a body lumen having a tubular interior surface, including:

• a radially self-expandable support structure having first and second opposite ends and including a plurality of elongate structural filaments that are interwoven, the support structure expandable from a reduced-diameter compressed state to a self-supporting and lumen-engaging expanded state, the support structure having a tubular portion for engaging the tubular interior surface of the lumen in the expanded state;
• a flexible fluid flow-occluding membrane including polymeric filaments interwoven with the structural filaments and coextensive with at least a portion of the length of the support structure;
• and
• constriction means for constricting a portion of the support structure and membrane for occluding fluid flow through the body lumen when the support structure is in the lumen-engaging expanded state.
