ELECTRICAL CONTACT FOR OCCLUSIVE DEVICE DELIVERY SYSTEM

摘要

An occlusive coil delivery system (10) includes a delivery wire (210) having a distal end (222) coupled to an occlusive device (300) via an electrolytically severable junction (250), and an electrical contact (216) secured to a proximal end (214) of the delivery wire, which has a non-linear configuration (211) 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.
