Occlusive implants are provided with various embodiments of active and/or passive release structures. Systems for delivering the occlusive implants as well as methods for making and delivering the implants are also provided.

Occlusive implants with fiber-based release structures

An occlusion device for a vascular or biological lumen includes a plurality of coiling members held together at both the proximal and distal ends by retaining features. A restraining loop can hold coiling members together at a point along a length of the coiling members. The coiling members are delivered simultaneously to form a coil pack to occlude a target location in the lumen. One or more of the coiling members has at least a portion with a larger curl diameter than other coiling members to secure the occlusion device against lumen walls at the target location. The coil members may have different or varying material moduli. The device may be used, for example, for occluding a vessel to block blood flow to an artery supplying blood liver (hepatic artery), kidney (renal artery), spleen (splenic artery) or intestines (mesenteric artery).

Occlusion device for a vascular or biological lumen

A delivery apparatus for a lumen occlusion device includes a pusher configured for releasably coupling with and pushing and pulling a proximal end of the occlusion device in a distal or proximal direction and a distal control wire capable of releasably coupling with the distal end and the proximal end of the occlusion device. The control wire may be configured for moving the distal end of the occlusion device in both proximal and distal directions allowing precise simultaneous control of both proximal and distal ends of the occlusion device. Control of both ends provides for placing the occlusion device in tension during delivery through a delivery catheter, thereby reducing delivery forces, achieving greater compaction of the occlusion device in the lumen, and precisely locating both distal and proximal ends of the occlusion device within the lumen.

Systems, devices, and methods for delivering a lumen occlusion device using distal and/or proximal control

An occlusion system () provides a trimmable continuous embolic coil () that is 'cut to length' at the end of its deployment into the target occlusion site. A delivery device () provides the 'cut to length' feature for the continuous embolic coil.
