To permit placement of an embolic device embolic device at a desired indwelling position in an aneurysm and readjustment of the indwelling position of the embolic device that is already indwelled, a medical instrument set includes an embolic device insertable into a delivery catheter, and configured to, when the embolic device is indwelled in an aneurysm, absorb a liquid in the aneurysm and expand, and an elongated delivery pusher insertable into the delivery catheter and configured to push the embolic device out of the delivery catheter into the aneurysm. The delivery pusher includes an elongated main body and an aspiration lumen that is formed to penetrate to main body in an axial direction from a distal end to a proximal end of the main body and causes the delivery pusher to aspirate and hold the embolic device.

To displace an amount of curvature of a curved section at the tip of an insertion part that delivers an embolic device into an aneurysm to facilitate insertion/removal operations, an elongated and hollow delivery catheter includes an elongated main body, and a curved section at the distal side of the main body that curves to gradually move away from a center axis of the main body. The curved section has a lumen that continues from the distal end of the curved section toward the base end of the main body and enables delivery of an embolic device into an aneurysm through the lumen. The delivery catheter is usable with an elongated correcting member that is insertable into the delivery catheter lumen and that displaces the curved section so that an amount of curvature of the curved section after insertion is less than that before insertion.

An embolic implant includes a detachment feature configured to engage and be released from a delivery member's engagement system. The engagement system can include a loop wire extending through an opening of the detachment feature a pull wire extending through the loop wire to secure the detachment feature to a delivery tube of the delivery member. The detachment feature can include a distal extension configured to engage a distal end of the pull wire to inhibit the pull wire from moving distally into the implant. The detachment feature can also include a sleeve to align the pull wire to the distal extension and/or provide a friction force against the pull wire to inhibit longitudinal movement of the distal end of the pull wire.

A hydrogel stent for cerebral aneurysm includes a hydrogel polymer, and a stent body wrapping at least a portion of the hydrogel polymer. The stent body is expandable in a cerebral aneurysm of a blood vessel. The stent body is provided in a mesh type surrounding at least a portion of the hydrogel polymers. An embolization device for cerebral aneurysm, includes a hydrogel stent for cerebral aneurysm; a micro-conduit providing a movement path for guiding the hydrogel stent to a cerebral aneurysm of a blood vessel; and a pusher wire connected to the hydrogel stent to be movable in the movement path.

The present invention provides a braided implant with a retractable dual proximal layer and methods for administering the braided implant to treat aneurysms. The implant can include a tubular braid that can be set into a predetermined shape, compressed for delivery through a microcatheter, and implanted in at least one implanted position that is based on the predetermined shape and the geometry of the aneurysm in which the braid is implanted. The implant can also have a retractable dual layer at the proximal end of the device made of the same braid to provide additional coverage at the neck of the aneurysm. The dual layer can be pressed distally into a first implanted portion of the tubular braid, moving the first portion of the tubular braid towards the distal portion of an aneurysm wall so that the implant can partially or completely occlude an aneurysm neck.

A device for occluding a vasculature of a patient including a micrograft having an absorbent polymeric structure with a lumen of transporting blood. The micrograft has a series of peaks and valleys formed by crimping. The occluding device is sufficiently small and flexible to be tracked on a guidewire and/or pushed through a microcatheter to a site within the vasculature of the patient. Delivery systems for delivering the micrografts are also disclosed.

In some aspects, the present disclosure provides a delivery device for delivering a detachable medical implant that comprises an elongated delivery member and a first engagement portion. The first engagement portion comprises a first proximal-facing surface, a first distal-facing surface, and a first lumen that is configured to accommodate an activation wire, wherein at least 50% of a surface area of the first proximal-facing surface is angled away from a proximal end of the first engagement portion. In other aspects, the present disclosure provides a medical delivery system comprising: such a delivery device; an implantable device comprising a medical device portion and a second engagement portion, the second engagement portion comprising a second lumen configured to accommodate an activation wire, a second proximal-facing surface and a second distal-facing surface; and an activation wire. Other aspects pertain to methods of medical device delivery using such a medical delivery system.

A joint stabilization (reduction) system and associated methods and tools for placement of the system in an open or minimally invasive technique. The joint stabilization system includes a flexible prosthetic band for stabilizing the bones in proper position and a connector mechanism for joining the two ends of the prosthetic band around the bones. One end of the prosthetic band can be permanently attached to the connector.
