Abstract
An embolic coil implant having a stretch resistant fiber therethrough and dual-functional engagement feature at its proximal end is provided. The stretch resistant fiber can be effective to limiting separation of windings of the embolic coil. The engagement feature can provide an attachment for securing the embolic coil to an engagement system of a delivery tube and for securing the stretch resistant fiber at the proximal end of the embolic coil.
Claims8
An embolic implant comprising:
- an embolic coil comprising a lumen therethrough, a proximal end, and a distal end;
- a detachment feature affixed to the embolic coil approximate the proximal end of the embolic coil;
- and
- a stretch resistant fiber engaged to the detachment feature, extended through the lumen of the embolic coil, and affixed to the embolic coil approximate the distal end of the embolic coil,
- wherein the stretch resistant fiber is effective to limit separation of windings of the embolic coil as the embolic coil is reshaped;
- wherein the lumen of the embolic coil comprises a first inner diameter in a non-expanded portion of the lumen and a second inner diameter in an expanded portion of the lumen;
- wherein the detachment feature comprises a proximal portion disposed proximally from the lumen and a distal portion disposed within the lumen;
- wherein the proximal portion comprises a first width measuring greater than the first inner diameter of the lumen;
- and
- wherein the distal portion comprises a second width measuring greater than the first inner diameter and about equal to the second inner diameter of the lumen.
