Methods and apparatuses for blood vessel occlusion
First Claim
1. An occlusion device delivery system, comprising:
- a catheter having a lumen extending between distal and proximal portions, the distal portion having proximal and distal apertures extending through a wall of the catheter;
an expandable coiled implant, wound about the distal portion, comprising a wire and having proximal and distal sections, the proximal section having a first segment that extends within the proximal aperture, the distal section comprising a second segment that extends within the distal aperture, the wire having a first cross-sectional profile between the first and second segments and a reduced cross-sectional profile in the first and second segments that is smaller than the first cross-sectional profile; and
an elongate member extending through the lumen and engaging and radially restraining the first segment within the proximal aperture and the second segment within the distal aperture.

Abstract
An occlusion device delivery system and methods are provided in which an expandable coiled implant can be delivered using the delivery system. The system can comprise a catheter having a lumen extending between distal and proximal portions. The distal portion can have proximal and distal apertures extending through a wall of the catheter. The expandable coiled implant, which can be wound about the distal portion, can have a proximal section that extends within the proximal aperture and a distal section that can extend radially within the distal aperture. Further, the system can comprise an elongate member that extends through the lumen and engages and radially restrains the at least one of the proximal and distal sections within its respective aperture while engaged with the member.

12. An occlusion device delivery system, comprising:
-
a catheter having proximal and distal sidewall apertures opening to a lumen of the catheter; an expandable helical implant carried by the catheter, the implant comprising proximal and distal sections, the proximal section having a first notch positionable across the proximal aperture in an engaged position, the distal section comprising a second notch positionable across the distal aperture in the engaged position; and an elongate member assembly extending through the lumen to engage the first notch at the proximal aperture and the second notch at the distal aperture to restrain the implant relative to the catheter. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
