1. An assembly for delivering an implant to a target location within a body lumen, comprising:
- a catheter comprising a proximal portion, a distal portion, and a helical coil extending in a first helical direction and connecting the proximal portion to the distal portion, the coil being defined by a kerf between adjacent windings of the coil; and
an implant comprising a first end portion and a second end portion, wherein, the implant is biased to a relaxed state, andwherein, in an engaged configuration, (i) the catheter proximal portion engages the implant first end portion and (ii) the catheter distal portion engages the implant second end portion, and (iii) the implant applies a torque to the catheter to reduce a width or pitch of the kerf between adjacent windings of the catheter coil.

Abstract
An implant may include a frame and a cover to facilitate endoluminal vessel occlusion, selective release of embolic material toward a target region, and/or endoluminal stenting. The frame of the implant provides radial expansion properties to secure the cover within a body vessel. The cover and/or the frame can occlude flow of a fluid through the body vessel.

11. An assembly for delivering an implant to a target location within a body lumen, comprising:
-
a catheter comprising a proximal portion, a distal portion, and a plurality of filaments extending in a first helical direction and connecting the proximal portion to the distal portion; and an implant comprising a first end portion and a second end portion, wherein the implant is biased to a relaxed state and wherein, in an engaged configuration, (i) the catheter proximal portion engages the implant first end portion and (ii) the catheter distal portion engages the implant second end portion, and (iii) the implant applies a torque to the catheter to reduce a width or pitch of a gap between adjacent filaments. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
