Embodiment Construction

[0032] For the following defined terms, unless a different definition is given in the claims or elsewhere in this specification, these definitions shall apply.

[0033] All numerical values ​​herein, whether expressly indicated or not, are considered to be modified by the term "about". The term "about" generally refers to a range of values ​​that would be considered equivalent to (ie, having the same function or result) the recited value. In many instances, the term "about" may include numbers that are rounded to the nearest significant figure.

[0034] The recitations of numerical ranges by endpoints include all numbers subsumed within that range (eg, 1 to 5 includes 1, 1.5, 2, 2.75, 3, 3.80, 4, and 5).

[0035] As used in this specification and the appended claims, the singular forms "a", "an" and "the" include plural referents unless the context clearly dictates otherwise. As used in this specification and the appended claims, the term "or" is generally employed in its se...

Abstract

A vaso-occlusive delivery system (10) includes a vaso-occlusive coil (300), delivery wire assembly (200), and a link (500). The vaso-occlusive coil defines a coil lumen (306) and has first and second coil windings (308) defining a coil opening (314) therebetween. The delivery wire assembly defines a delivery wire lumen (212), and includes an electrolytic detachment zone (260), a delivery wire conduit (214), and a delivery wire (252) attached to the delivery wire conduit and extending through the delivery wire lumen distal of the delivery wire conduit. The link defines a link lumen (510) and has link body (506) including a proximal end of the link body defines an link opening (512) in communication with the link lumen and a distal end of the link body includes a link detent (514) extending radially from the link body, through the coil opening, securing the link body and the delivery wire assembly to the vaso-occlusive coil.

Description

technical field [0001] The technical field of the invention relates generally to systems and delivery devices for implanting a vaso-occlusive device in a blood vessel of a human or animal patient for embolization or vaso-occlusion. More specifically, the present invention relates to securing a vaso-occlusive coil to a pusher assembly. Background technique [0002] Vaso-occlusive devices or implants are widely used for a number of reasons, including the treatment of intravascular aneurysms. Commonly used vaso-occlusive devices include a soft, helically wound coil formed by winding a platinum (or platinum alloy) wire strand around a "primary" mandrel. The coil is then wound around a larger "secondary" mandrel and heat treated to form the secondary shape. For example, U.S. Patent No. 4,994,069 to Ritchart et al. describes a vaso-occlusive device that, when expanded for positioning through the lumen of a delivery catheter, assumes a linear helical primary shape and is Release...
