Expandable intervertebral implant

An expandable intervertebral implant is provided for insertion into an intervertebral space defined by adjacent vertebrae. The expandable intervertebral implant includes a pair of outer sleeve portions and an inner core disposed between the outer sleeve portions. Movement of the inner core relative to the outer sleeve portions causes the outers sleeve portions to deflect away from each other, thereby engaging the expandable intervertebral implant with the vertebrae and adjusting the height of the intervertebral space.

Devices, systems, and methods for clamping a leaflet of a heart valve

The present disclosure relates generally to the field of medical devices for clamping a leaflet of a heart valve. In particular, the present disclosure relates to medical devices, systems, and methods for delivering artificial chordae tendineae in a patient. In an embodiment, a system may include a clamp having a plurality of arms at a first end. The plurality of arms may have a closed configuration in which the arms are oriented toward each other, and an open configuration in which the arms are oriented away from each other. A spring portion may be coupled to the plurality of arms at a second end that is configured to bias the arms to the closed configuration. The arms of the clamp may be configured to fixedly engage with a leaflet of the heart valve. The second end of the clamp may be configured to couple to an artificial chordae tendineae.

External male incontinence clamp

An incontinence clamp is provided. The incontinence clamp includes an upper clamp arm and a lower clamp arm. Each of the upper and lower clamp arms include a first end, a second end, an inner surface and an outer surface. The inner surfaces face each other. A hinge pivotally connects the first ends of the upper and lower clamp arms together. An upper guide is coupled to the inner surface of the upper clamp arm and a lower guide is coupled to the inner surface of the lower clamp arm. A connector releasably connects the second ends of the upper clamp arm and the lower clamp arm together.

SYSTEMS AND METHODS FOR RESHAPING A HEART VALVE

The present disclosure includes a device for reshaping a heart valve. The device may include a central ring about a central axis and a plurality of arms coupled to the central ring, each of the arms coupled to the central ring at a pivot point at a first end of the arm, the arm comprising an attachment feature at a second point along the arm, the pivot point configured to allow movement of the arm about the pivot point through a plane extending radially from the central axis through the arm. Additionally, the plurality of arms may be contractable and may be extendable such that the hooks extend beyond a dilated heart valve. The present disclosure also includes associated methods and systems.

NEGATIVE POISSON`S RATIO MATERIALS FOR INTRAOCULAR LENSES
20230149153 · 2023-05-18 ·

An intraocular lens includes a substantially circular lens element formed of a transparent material and one or more haptics extending outwardly from an outer edge of the lens element. The one or more haptics are formed of a polymer foam material having a negative Poisson's ratio (NPR) and are configured to couple the intraocular lens to an eye of a patient. The lens includes an inner region having a first index of refraction and an outer region disposed circumferentially surrounding the inner region, the outer region having a second index of refraction different from the first index of refraction.

TAPERED PROSTHETIC HEART VALVES WITH VALVULAR STRUCTURES FORMING TAPERED FLOW CHANNELS
20230200985 · 2023-06-29 ·

A prosthetic heart valve has a frame and a valvular structure coupled thereto. The valvular structure has multiple leaflets, with paired tabs from the leaflets forming commissure tab assemblies that couple the valvular structure to the frame. The frame is tapered with its inflow end diameter being smaller than its outflow end diameter. The valvular structure is constructed such that a flow channel formed by the leaflets is also tapered, with the inlet end cross-section being smaller than the outlet end cross-section. The commissure tab assemblies are attached to the frame with leaflet bending axes at or adjacent to the radially-inner surface of the frame. During systole, separation of blood flow induced by the tapered geometry of the flow channel generates an annular back flow region adjacent to the inner surface of the valve at the outflow end, which prevents the free edge of the leaflets from contacting the frame.

Tissue Gripper and Valve Clamping Device
20230200995 · 2023-06-29 ·

A tissue gripper (60), includes a connecting frame (62) and two gripping arms (64). The connecting frame (62) includes two spaced connecting pieces (623), and the two gripping arms (64) are respectively arranged at sides of the two connecting pieces (623). Each gripping arm (64) includes a bending section (641) connected to the corresponding connecting piece (623) and a gripping section (643) connected to the bending section (641). The width of the bending section (641) is less than the width of the gripping section (643) and the width of the connecting piece (623), such that the weight of a valve clamping device (100) can be reduced, and the pulling force to pull the two gripping arms (64) up to a central axis can also be reduced. Also provided is the valve clamping device (100) provided with the tissue gripper (60).

UNCAGING STENT

A stent (scaffold) or other luminal prosthesis comprising circumferential structural elements which provide high strength after deployment and allows for scaffold to uncage, and/or allow for scaffold or luminal expansion thereafter. The circumferential scaffold is typically formed from non-degradable material and will be modified to expand and/or uncage after deployment.
