Intervertebral disc and insertion methods therefor

A method of inserting an intervertebral disc implant into a disc space includes accessing a spinal segment having a first vertebral body, a second vertebral body and a disc space between the first and second vertebral bodies. The method includes securing a first pin to the first vertebral body and a second pin to the second vertebral body, using the first and second pins for distracting the disc space, and providing an inserter holding the intervertebral disc implant. The method also desirably includes engaging the inserter with the first and second pins, and advancing the inserter toward the disc space for inserting the intervertebral disc implant into the disc space, whereby the first and second pins align and guide the inserter toward the disc space.

Free Edge Supported Mitral Valve Methods
20230132651 · 2023-05-04 ·

A method for placing a transcatheter stent-valve having replacement leaflets that are attached along their free edges. The stent-valve frame has supports that extend distally of the replacement leaflets to fastening sites. The replacement leaflets are attached along a leaflet base forming a linear attachment to the stent-valve frame. The free edges of the leaflets have cords attached; the cords attach the leaflets to the supports. The stent-valve can be a single component stent-valve or it can be a second component that attaches to a first component or dock.

Device for anastomotic bypass

A stent including a tubular body formed of one or more interwoven wires, a first anchor member disposed adjacent the first open end of the stent, a second anchor member disposed adjacent the second open end of the stent, and at least one divider disposed between the first and second anchor members. The first and second anchor members and the divider extend radially outward from the tubular body to divide the tubular body into at least a first saddle region extending between the first anchor member and the divider and a second saddle region extending between the second anchor member and the divider.

Biliary stents and methods

A tissue lumen stent is provided with a body having an elongated tubular configuration and a foreshortened configuration. In the foreshortened configuration, downstream and upstream ends of the body expand radially into downstream and upstream flange structures, leaving a generally cylindrical saddle region therebetween. In some embodiments, the flange structures are non-symmetrical with respect to one another. Systems and methods of using the stents are also disclosed.

ADJUSTABLE ANNULOPLASTY RING AND DELIVERY SYSTEM
20230165681 · 2023-06-01 ·

An annuloplasty ring for repair of mitral and tricuspid valves that can be shape adjusted once installed to fine-tune the shape and correct for small errors in the inherently imprecise sizing process. The ring has an adjustable 3D ring core of malleable metal that can be reshaped in real-time during the procedure before or after the patient is weaned off-pump by applying simple displacements to a cable and housing arrangement. The shape of the annuloplasty ring is adjusted incrementally in steps until an optimum level of regurgitation reduction is attained. Once the surgeon is satisfied with the result, the delivery system can be can easily detached from the implant and removed. The thickness of the core could be continuously variable to control how and where deformation occurs. The ring may also incorporate an expansion joint to enable a subsequent valve-in-ring procedure.

Methods and apparatus for luminal stenting
09801744 · 2017-10-31 · ·

Described herein are flexible implantable occluding devices that can, for example, navigate the tortuous vessels of the neurovasculature. The occluding devices can also conform to the shape of the tortuous vessels of the vasculature. In some embodiments, the occluding devices can direct blood flow within a vessel away from an aneurysm or limit blood flow to the aneurysm. Some embodiments describe methods and apparatus for adjusting, along a length of the device, the porosity of the occluding device. In some embodiments, the occluding devices allows adequate blood flow to be provided to adjacent structures such that those structures, whether they are branch vessels or oxygen-demanding tissues, are not deprived of the necessary blood flow.

Collapsible cardiac implant and deployment system and methods

A collapsible device, such as an annuloplasty ring or prosthetic heart valve, is configured to be collapsed prior to being introduced into a patient via minimally-invasive access points such as port holes or intercostal incisions. A holder is configured to hold the collapsible device, and to selectively collapse the device for introduction into the patient and then re-enlarge the device at the desired deployment site. Collapsible devices include devices that can hingedly fold about hinge lines, and devices that can elongate to form substantially spiral forms with reduced diameters.

Posterior-Stabilized Knee Implant Components and Instruments

Patient-adapted articular repair systems, including implants, instruments, and surgical plans, and methods of making and using such systems, are disclosed herein. In particular, various embodiments include knee joint articular repair systems designed for posterior stabilization, including patient-adapted posterior-stabilizing features.

Trapeziometacarpal joint implant and associated methods
09788959 · 2017-10-17 · ·

A trapeziometacarpal joint implant includes a body defining a median plane, a metacarpal joint surface, and a trapezium joint surface. A first central region of the metacarpal joint surface is situated on an opposite side of the median plane from a second central region of the trapezium joint surface. The first and second central regions correspond to profiles of a first axial segment and a second axial segment, respectively. The first and second axial segments are one of a cylinder, a cone and a torus and are centered on a first axis and a second axis, respectively, where the first and second axes, as projected on the median plane, are substantially perpendicular to each other.

METHOD AND APPARATUS FOR RESTRICTING FLOW THROUGH AN OPENING IN THE SIDE WALL OF A BODY LUMEN, AND/OR FOR REINFORCING A WEAKNESS IN THE SIDE WALL OF A BODY LUMEN, WHILE STILL MAINTAINING SUBSTANTIALLY NORMAL FLOW THROUGH THE BODY LUMEN

A method for making a device for causing thrombosis of an aneurysm, wherein said device comprises a single elastic filament configurable between (i) an elongated, substantially linear configuration, and (ii) a longitudinally-contracted, substantially three-dimensional configuration, said method comprising: providing a sheet of shape memory material; producing a single filament, two-dimensional interim structure from said sheet of shape memory material; mounting said single filament, two-dimensional interim structure to a fixture so that said single filament, two-dimensional interim structure is transformed into said longitudinally-contracted, substantially three-dimensional configuration; and heat treating said single filament, two-dimensional interim structure while it is mounted to said fixture so as to produce said device in its longitudinally-contracted, substantially three-dimensional configuration.
