Stent graft delivery system

A system for treating an aneurysm comprises an elongate flexible shaft and an expandable member. An expandable scaffold is disposed over the expandable member and may be expanded from a collapsed configuration to an expanded configuration. A double-walled filling structure is disposed over the scaffold and has an outer wall and an inner wall. The filling structure is adapted to be filled with a hardenable fluid filing medium so that the outer wall conforms to an inside surface of the aneurysm and the inner wall forms a substantially tubular lumen to provide a path for blood flow. In the expanded configuration the scaffold engages the inner wall of the filling structure. A tether is releasably coupled with the filling structure and the flexible shaft thereby constraining axial movement of the structures relative to each other.

Radially expandable annulus reinforcement prosthesis
10881522 · 2021-01-05 ·

An intervertebral implantation system for restoring disc height and vertebral alignment, while allowing dynamic mobility and stabilization of the vertebral segment, and minimally invasive methods of implanting the same. The implantation system includes an annular reinforcement implant, including an elastomeric balloon inserted into the hollow or interior of a tubular sleeve, and secured only at a first and second neck portions to a securement element coupled to an attachment fixture, forming an annular structure attached to the outer margin of the annulus fibrosus. When the prosthetic implant is in a contracted state the tubular sleeve is redundant and undulated, forming folds, gathered loosely around the circumference of the inner balloon. Upon pressurized inflation with in-situ curable polymer, the elastomeric balloon elongates and expands circumferentially, and the tubular sleeve stretches and unfolds, constraining further expansion and elongation of the elastomeric balloon. The attachment fixture is configured to provide secure attachment to the outer margin of the annulus fibrosus. A temporary, high pressure vertebral distraction balloon is utilized to aid in vertebral distraction during a surgical procedure to implant the annular reinforcement implant.

Expandable coil spinal implant

Coiled spinal implants for disc, vertebral body, and spinal motion segment replacement or reconstruction comprise a plurality of loops and spaces between the loops, with the loops formed of a hollow material and having a plurality of apertures or a longitudinal gap that extend(s) through the sidewalls of the loops and into the hollow center. The coiled implants include one or more balloons within the hollow center, the spaces between the coil loops, and/or within the central void that the coil surrounds. Filling the balloon expands the loops and thereby increases the height of the coil. Bone graft material or bone cement may be deployed from the apertures or gap.

A central inflatable distractor and a perimeter balloon are inserted into the disc space in uninflated configurations. The central inflatable distractor is then expanded, thereby distracting the vertebral endplates to the controlled height of the central inflatable distractor. The perimeter balloon is then inflated with a curable substance. The perimeter balloon expands as it is filled with the curable substance and conforms to the void remaining in the disc space around the central inflatable distractor, thereby creating a horseshoe shape. Once the flowable material in the perimeter balloon has cured, the central inflated distractor can be deflated and removed. The remaining void (or inner space) is then packed with graft for fusion.

Intervertebral Body Fusion Device Expanded With Hardening Material
20200352730 · 2020-11-12 ·

An expandable, intervertebral spacer includes a top component and a base component in engagement with the top component, the base component defining at least one channel for receiving a hardening material, and placement of the hardening material within the channel causes the top component to move between a first position in which the top component is a first distance from the base component and a second position in which the top component is a second distance from the base component, the second distance being greater than the first distance. The hardening material can be removed from the channel by a flexible coring tool, and the top component forced toward the base component to collapse the spacer.

Inflatable spinal implants and related systems and methods
10821002 · 2020-11-03 · ·

Inflatable spinal implants are disclosed for intra-vertebral or inter-vertebral reduction and fixation of osteoporotic fractures in a spine. An inflatable implant may include an inflatable member having an interior for receiving a hardenable fluid and an expandable jacket to cause differential and directional expansion of the inflatable member. A one-way valve may be configured to prevent hardenable fluid from escaping out of the inflatable member. An inflatable implant may include a connection fixation device having a fluid coupling configured for releasable engagement with an inflation cannula and an anchoring portion configured for holding the implant in place within a vertebra. The fluid coupling may also be configured for releasable engagement with an anti-rotation device, which may be used to hold the implant stationary to facilitate engagement and disengagement of the inflation cannula with the fluid coupling. Related systems and methods are also described.

INTERBODY DISTRACTION AND STABILISATION DEVICE

An interbody distraction and stabilisation device, comprising an implant comprising a casing for containing a filling material and a distraction element that is associated with the casing and that has opposing first and second sides, the distraction element having a first state in which the distraction element has a first height and a second state in which the distraction element has a second height greater than the first height so as to keep body parts spaced apart from each other.
