Abstract
A microcatheter deliverable implant is provided formed of an elongated wire of a diameter capable of delivery through the axial passage of such a microcatheter. A first portion of the formed implant forms a coiled first section larger in diameter than an anomaly to be blocked. A second portion formed by the coiled wire engages the implant between the first and second portions to block communication of fluid through the anomaly.
Claims16
A microcatheter deliverable implant, comprising:
- an elongated wire formed of memory material;
- said wire translatable through a distal end of an axial conduit in a deployment at an implant site;
- a first portion of said wire coiling during said deployment, to form a first section of said implant having a first diameter;
- said wire extending from a central portion of said first section, in an axial winding, said axial winding extending a distance from said first section;
- at a distal end of said axial winding, opposite said central portion, a second portion of said implant formed by said wire coiling around said axial winding, in a direction toward said first section to mid section of said axial winding, in-between said first portion and said second portion;
- said second portion of said implant defining a second diameter of said second portion of said implant;
- whereby said first portion of said implant is deployable on a first side of said of an anomaly in a blood circulation system of a patient, and said second portion is deployable on a second side of said anomaly, thereby forming a sandwiched engagement of said anomaly between said first portion and said section portion and blocking communication between said first side and said second side of said anomaly.
