Medical stent designs are disclosed. An example stent includes a tubular scaffold having a proximal end and a distal end. The tubular scaffold includes a first filament extending between the proximal end and the distal end, the first filament including a first biodegradable region positioned adjacent to a second biodegradable region. Further, the first biodegradable region includes a first biodegradable material, the first biodegradable material having a first rate of degradation. The second biodegradable region includes a second biodegradable material, the second biodegradable material having a second rate of degradation, wherein the first rate of degradation is different from the second rate of degradation.

Intraocular lens and methods for optimization of depth of focus and the image quality in the periphery of the visual field. The intraocular lens (600) comprises a central part and a peripheral part, the central part being the optical part (600) and the peripheral part comprising mechanical fasteners (603), and the central part comprises: an aspherical concave anterior surface (601), which is the surface closest to the iris of the eye once the lens (600) has been implanted in the eye, and an aspherical convex posterior surface (602), which is the surface closest to the retina of the eye once the lens (600) has been implanted in the eye, such that the radius of curvature of the posterior surface (602) of the central part is smaller than the radius of curvature of the anterior surface (601) of the central part, with a ratio between radii of between 2 and 6, and the mechanical fasteners (603) are arranged at an angle (605) of between 0° and 10° with respect to a plane passing through the joints between the central part and the peripheral part and which is perpendicular to the optical axis of the eye in which the lens (600) is intended to be implanted.

The present disclosure describes various embodiments of adjustable implants, particularly permanent breast implants, intended for implantation into a subject, particularly a human subject. In some embodiments, the adjustable implant comprises a shell including a resilient shell membrane, a first reservoir containing a fluid, e.g., a saline, a second reservoir including a resilient second-reservoir membrane, and a pump. The pump may include a first pump actuator, a first pump inlet, and a first pump outlet. The first reservoir and second reservoir may be disposed within the shell and be in fluid communication via the pump. Fluid may be transferred between the two reservoirs to change the profile of the implant.

Systems for mitral valve repair are disclosed where one or more mitral valve interventional devices may be advanced intravascularly into the heart of a patient and deployed upon or along the mitral valve to stabilize the valve leaflets. The interventional device may also facilitate the placement or anchoring of a prosthetic mitral valve implant. The interventional device may generally comprise a distal set of arms pivotably and/or rotating coupled to a proximal set of arms which are also pivotably and/or rotating coupled. The distal set of arms may be advanced past the catheter opening to a subannular position (e.g., below the mitral valve) and reconfigured from a low-profile delivery configuration to a deployed securement configuration. The proximal arm members may then be deployed such that the distal and proximal arm members may grip the leaflets between the two sets of arms to stabilize the leaflets.

The invention relates surgical abdominal methods of treating obesity in a patient by implanting a volume filling device that, when implanted in a patient, reduces the food cavity in size by a volume substantially exceeding the volume of the volume filling device. Also disclosed is a laparoscopic instrument for providing a volume filling device to be invaginated in the stomach wall of a human patient to treat obesity.

An apparatus for treating obesity comprises a volume filling device formed by at least two segments and is provided and following implantation, the device is placed resting against the stomach wall of the patient to reduce the inner volume of the stomach, thereby affecting the patients appetite.

Pneumatic Structure and Associated Production Method

The structure (10) comprises an elastically deformable body (12) defining at least one network of internal cavities (14), each internal cavity (14) having a closed contour in at least one section of the internal cavity (14),

Each internal cavity (14) is able to be pressurized so as to make the elastically deformable body (12) pass from a rest configuration to at least one pressurized configuration,

In each pressurized configuration, the elastically deformable body (12) has a macroscopic metric that is distinct from its macroscopic metric in the rest position,

In each pressurized configuration, the radius of curvature of an outer surface of the elastically deformable body (12), considered regarding each internal cavity (14) adjacent to the outer surface, is greater than twice the size of the internal cavity (14) adjacent to the outer surface.

In a representative embodiment, a method comprises implanting first and second inflatable bodies within an annulus of a native heart valve by securing the inflatable bodies to tissue of the native heart valve with sutures, and implanting a prosthetic heart valve between the inflatable bodies such that the prosthetic heart valve is retained within the annulus by the inflatable bodies.

A two-part aortic annular support system for supporting an aortic annulus during aortic valve repair procedures for prevention of further annular dilation. The first part comprises a composite annular ring that is positionable from within an aortic valve into the left ventricular outflow tract at the level of annular plane. The composite ring comprises a semi-rigid section and a resiliently deformable section. The semi-rigid section is shorter in length than the deformable section. The deformable section is extendible into a commissure of the aortic valve. The second part is a resilient band that is positionable external to the aortic root. The resilient band is securable to the composite ring through the aortic annulus by suturing. The present disclosure also relates to a use of the aortic annular support system and a method of inserting and securing the aortic annular support system during a surgical intervention.
