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.
Claims19
A method of assembling an implant delivery system, comprising:
- providing an implant, in a relaxed state, to a catheter having a kerf (1) extending from and through an outer surface of the catheter into a lumen of the catheter, and (2) extending in a first helical direction and defining opposing sides along a helical coil;
- engaging a first end portion of the implant with a proximal portion of the catheter;
- and
- engaging a second end portion of the implant with a distal portion of the catheter, such that the implant is held in a torsional state by the catheter, and such that the implant applies a torque to the catheter to cause opposing sides of adjacent windings of the coil between the proximal portion and the distal portion to be pulled toward each other.

A method of assembling an implant delivery system, the method comprising:
- providing 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;
- engaging a first end portion of an implant with the catheter proximal portion, the implant being biased to a relaxed state;
- moving the implant away from the relaxed state to a collapsed state and engaging a second end portion of the implant with the catheter distal portion such that the implant applies a torque to the catheter to reduce a width or pitch of the kerf between adjacent windings of the catheter coil.
A method of assembling an implant delivery system, the method comprising:
- providing a catheter comprising a proximal portion, a distal portion, and a kerf that defines windings of the catheter that connect the proximal portion to the distal portion and are movable relative to each other;
- and
- compressing an implant onto the catheter to couple (i) a first end portion of the implant to the catheter proximal portion and (ii) a second end portion of the implant to the catheter distal portion such that the implant is engaged on the catheter in a collapsed state to apply a torque to the catheter, thereby reducing a width or pitch of a gap between adjacent windings.
