First Claim
Patent Images
1. An occlusive device delivery system, comprising:
- a delivery wire having a distal end coupled to an occlusive device via an electrolytically severable junction; and
an electrical contact secured to a proximal end of the delivery wire, the proximal end of the delivery wire having a non-linear configuration so as to strengthen a mechanical connection with the electrical contact.

Abstract
An occlusive coil delivery system includes a delivery wire having a distal end coupled to an occlusive device via an electrolytically severable junction, and an electrical contact secured to a proximal end of the delivery wire, which has a non-linear configuration so as to strengthen a mechanical connection with the electrical contact and/or increase electrical conductivity with the electrical contact over a linear configuration. The configuration may be, by way of non-limiting examples, a “U” shape, a spiral, a knot, or a twisted wire. The electrical contact is a conductive material that substantially envelopes the proximal end configuration of the delivery wire.
