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.
Claims23
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, a second end portion, a torsion state, and a relaxed state, wherein the implant is biased to the relaxed state and wherein, while the implant is in the torsion state, the proximal portion engages the first end portion, the distal portion engages the second end portion, and the implant applies a torque to the catheter.
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, a second end portion, a torsion state, and a relaxed state, wherein the implant is biased to the relaxed state and wherein, while the implant is in the torsion state, the proximal portion engages the first end portion, the distal portion engages the second end portion, and the implant applies a torque to the catheter.
A method of assembling an implant delivery system, comprising:
- providing an implant, in a relaxed state, to a catheter having a kerf 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 torsion state by the catheter, and such that the implant applies a torque to the catheter.
