Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
95 words
A vasoocclusive device adapter to be introduced into and anchored in a vascular lumen comprises an elongated, conical shaped, spiral coil extending along a longitudinal axis from one end of a first diameter loop to another end of a second diameter loop which is smaller than the first diameter loop, said second diameter loop at the other end of the elongated, conical shaped, spiral coil ends in an apex and has extending from the apex hook means for anchoring the device in the vascular lumen said hook means extending radially beyond said second diameter loop.
Claim 2
Dependent Claim
95 words
A vasoocclusive device adapter to be introduced into and anchored in a vascular lumen comprises an elongated, conical shaped, spiral coil extending along a longitudinal axis from one end of a first diameter loop to another end of a second diameter loop which is smaller than the first diameter loop, said second diameter loop at the other end of the elongated, conical shaped, spiral coil ends in an apex and has extending from the apex hook means for anchoring the device in the vascular lumen said hook means extending radially beyond said second diameter loop.
Claim 3
Dependent Claim
19 words
A device as claimed in claim 1, wherein the spiral coil is formed of a heat-sensitive resilient memory wire.
Claim 4
Dependent Claim
18 words
A device as claimed in claim 2, wherein the coil is coated by a biocompatible and thrombogenic material.
Claim 5
Dependent Claim
14 words
A device as claimed in claim 3, wherein the wire is coated with tungsten.
Claim 6
Dependent Claim
51 words
A device as claimed in claim 2, wherein the hook means is comprised by a terminal portion of said wire, said portion being bent to about a 90° angle with respect to the longitudinal axis and which terminates in a second intermediate bent portion in the form of an open hook.
Claim 7
Independent Claim
149 words
An apparatus for introducing a vasoocclusive device in a vascular lumen comprises, in combination, a vasoocclusive device having an elongated, conical shaped, spiral coil extending along a longitudinal axis from one end of a first diameter loop to an other end of a second diameter loop which is smaller than the first diameter loop, said second diameter loop at the other end of the elongated, conical shaped, spiral coil ends in an apex and has extending from the apex hook means for anchoring the device in the vascular lumen said hook means extending radially beyond said second diameter loop, and a cartridge comprises a tubular body for receiving said vasoocclusive device, said tubular body having an indexed scale indicating the position of each loop of the vasoocclusive device, and a pusher associate with said tubular body and said occlusive device for introducing said occlusive device into the vascular lumen.
