1. An implant device comprising:
- a first woven cylindrical layer having a first porosity;
said first woven cylindrical layer being formed from a single first wire crossing back and forth between a first end and a second end of said first woven cylindrical layer at a plurality of locations to form said first generally cylindrical shape with a plurality of loops at said first end and said second end; and
,a second woven cylindrical layer having a second porosity, forming a second generally tubular shape, and located within said first generally tubular shape;
said second woven layer being formed from one or more wires.
