Corneal implant
A corneal implant and methods of forming and implanting the implant are described. The corneal implant comprises a portion of corneal endothelial tissue and a portion of scleral tissue. The corneal implant is keyhole shaped, with a disc portion and a tail portion. The tail portion may further comprise a perforated section.
INTRAOCULAR LENSES
This document describes intraocular lenses and methods for their use. For example, this document describes intraocular lenses that are shaped with a concave posterior peripheral portion that mitigates occurrences of dysphotopsia. The intraocular lenses described herein are designed to reduce positive and negative dysphotopsias after cataract surgery.
OCULAR IMPLANT SYSTEMS
Described herein is an ocular implant system in which an implant (200) is deployed in a posterior space of the eye, for example, the suprachoroidal space or the subconjunctival space or the intrascleral space, with an access within the anterior chamber (160) for reducing intraocular pressure therein. The shunt (200) is implanted using an implantation device comprising a hollow shaft (330) mounted over a fixed shaft (320). The shunt (200) is located in a distal end of the hollow shaft (330) and adjacent a distal end of the fixed shaft (320), the distal end of the fixed shaft being located at a position behind the distal end of the hollow shaft. Once the distal end of the hollow shaft (330) with the shunt (200) is located at the desired depth within the posterior space, the hollow shaft is withdrawn over the fixed shaft towards the proximal end thereof to leave the shunt in the posterior space with an access within the anterior chamber (160).
CUSTOMIZED INTERVERTEBRAL PROSTHETIC DISC WITH SHOCK ABSORPTION
A prosthesis system comprises plates that can be positioned against vertebrae and a selected resilient core that can be positioned between the plates to allow the plates to articulate. The selected resilient core can be chosen from a plurality of cores in response to patient characteristics, such as age and/or intervertebral mobility, such that the prosthesis implanted in the patient is tailored to the needs of the patient. The plurality of cores may comprise cores with different resiliencies, and one of the cores can be selected such that the upper and lower plates articulate with the desired shock absorbing resiliency and/or maximum angle of inclination when the one selected core is positioned between the plates.
ADJUSTABLE INTRAOCULAR LENSES AND METHODS OF POST OPERATIVELY ADJUSTING INTRAOCULAR LENSES
Disclosed are adjustable intraocular lenses and methods of adjusting intraocular lenses post-operatively. In one embodiment, an adjustable accommodating intraocular lens comprises an optic portion and at least one haptic. At least part of the haptic can be made in part of a composite material comprising an energy absorbing constituent and a plurality of shrinkable and/or burstable microspheres. At least one of a base power of the optic portion can be configured to change in response to an external energy directed at the composite material.
Textile-based prothesis for laparoscopic surgery
The invention relates to a prosthesis (1) comprising a textile (2) of elongate shape defining a longitudinal axis A, and a reinforcing element comprising at least one semi-rigid elongate structure (8) connected to said textile, said structure being substantially parallel to said longitudinal axis A and having a distal end provided with at least one fastening element (4) distinct from said textile and capable of cooperating with a part of a tool (10) that is able to pass through said trocar, in order to temporarily couple said prosthesis to said tool.
Prosthetic heart valve
Embodiments of a radially collapsible and expandable prosthetic heart valve are disclosed. A valve frame can have a tapered profile when mounted on a delivery shaft, with an inflow end portion having a smaller diameter than an outflow end portion. The valve can comprise generally V-shaped leaflets, reducing material within the inflow end of the frame. An outer skirt can be secured to the outside of the inflow end portion of the frame, the outer skirt having longitudinal slack when the valve is expanded and lying flat against the frame when the valve is collapsed. A diagonally woven inner skirt can elongate axially with the frame. Side tabs of adjacent leaflets can extend through and be secured to window frame portions of the frame to form commissures. The window frame portions can be depressed radially inward relative to surrounding frame portions when the valve is crimped onto a delivery shaft.
Modular humeral prosthesis for an inverted shoulder prosthesis
The invention relates to a modular humeral prosthesis for an inverse shoulder prosthesis, comprising an anatomical shaft (1) and a separable epiphyseal head (2) which may be angularly orientated by rotation about the longitudinal axis (XX) of the anatomical shaft. The anatomical shaft and the epiphyseal head comprise complementary angular indexing means (11, 28) for relative rotational fixation.
Customized intervertebral prosthetic disc with shock absorption
A prosthesis system comprises plates that can be positioned against vertebrae and a selected resilient core that can be positioned between the plates to allow the plates to articulate. The selected resilient core can be chosen from a plurality of cores in response to patient characteristics, such as age and/or intervertebral mobility, such that the prosthesis implanted in the patient is tailored to the needs of the patient. The plurality of cores may comprise cores with different resiliencies, and one of the cores can be selected such that the upper and lower plates articulate with the desired shock absorbing resiliency and/or maximum angle of inclination when the one selected core is positioned between the plates.
Methods and devices for attaching or reattaching soft tissue to bone
Embodiments of the invention include implants, instruments, and methods for attaching or reattaching soft tissue (200, 2200) to a bone (100), that enable independent tensioning of multiple connectors such as sutures (60, 160, 2060, 2160) and enable redundant fixation between bone (100) and soft tissue (200, 2200). Some embodiments provide for improved accuracy of the placement of substantially parallel tunnels through which soft tissue (200, 2200) to bone (100) connectors such as sutures (60, 160, 2060, 2160) are passed.
