Abstract
The present invention provides systems and methods for accurately delivering embolic coils within a body lumen of a patient, as well as recapturing deployed embolic coils for removal or repositioning. In various embodiments, an embolic coil delivery system may include an elongate sheath with a lumen extending therethrough. An elongate shaft may be slidably disposed within the sheath. The shaft may comprise a split-distal end that defines an aperture. The split-distal end may be moveable between a contracted configuration and an expanded configuration. An embolic coil may include a proximal ball-tip that may be reversibly disposed within the aperture of the split-distal end.
