Compressible heart valve annulus sizing templates suitable for minimally-invasive or otherwise reduced accessibility surgeries. The sizing templates may be folded, rolled, or otherwise compressed into a reduced configuration for passage through an access tube or other such access channel. Once expelled from the access tube the sizing templates expand to their original shape for use in sizing the annulus. The templates may be formed of an elastomeric polymer material such as silicone, a highly elastic metal such as NITINOL, or both. Grasping tabs or connectors for handles permit manipulation from outside the body. A NITINOL wireform may be compressed for passage through an access tube and expelled from the distal end thereof into a cloth cover to assume a sizer shape.

A tear shaping structure or structures that shape a tear film of an eye thereby enabling a desired refractive effect. The tear shaping structure includes a supporting structure supporting a plurality of capillary action members, the capillary action members being spaced apart and arranged in such a way as to create a desired refractive lens effect by shaping the tear film of an eye.

A cross-linking device and system are disclosed. In various embodiments, a cross-linking device includes a main body including a sidewall, a corneal gripping portion positioned in the interior cavity and defining an anterior chamber and an ocular chamber and defining an aperture that is configured to allow passage of a portion of a cornea to extend into the anterior chamber. In various embodiments, the device includes a multi-purpose fluid port positioned on the sidewall and defining two or more fluid pathways that connect a pair of exterior ports to an anterior chamber port, and an ocular chamber port respectively to allow for fluids to pass into and out of the interior of the device. In various embodiments the device is constructed from elastomer and, in response to a vacuum, the corneal gripping portion is configured to conform to the eye and seal the anterior chamber.

Apparatus (40) for compressing a transcatheter cardiac stent-valve (10) comprises: a first compressor stage (100) including a hollow channel (42) with a tapered interior surface configured for compressing a stent-valve in response to longitudinal advancement of the stent-valve within the channel; and a second compressor stage (102) comprising a crimper for compressing a portion of the stent-valve without longitudinal advancement.

The present invention relates to a device (1) for introducing a flexible prosthesis into a surgical incision, comprising a globally tubular body (2) having a proximal end (2a) and a distal end (2b), said tubular body being designed for receiving the prosthesis in a folded configuration in a sliding way, wherein the tubular body is provided with an open longitudinal slit (3) extending from said proximal end (2a) to said distal end (2b), and wherein said distal end is provided with a distal semi-tubular rounded extension (2c).

The present invention relates to corneal implant, particularly the implant is useful for a corneal transplant, the implant avoids the direct contact between the patient tissue and a donated cornea.

An intraocular lens (IOL) includes one or more haptic structures coupled to hold the IOL (100A) system in an eye. The IOL also includes one or more mechanical-to-electrical transducers (107) that detect mechanical changes in the eye and, in response to the mechanical changes, output an electrical signal. An accommodation actuator (101) is electrically coupled to the one or more mechanical-to-electrical transducers, and in response to the electrical signal the optical power of the accommodation actuator changes.

A transfer sleeve includes a proximal portion defining a proximal channel. The proximal channel has a cross-sectional area that allows a shaft of the delivery system to fit within the proximal channel of the proximal portion. The transfer sleeve also includes a distal portion defining a distal channel. The distal channel has a cross-section area that allows the shaft of the delivery system to fit within the distal channel. Further, the transfer sleeve includes a body portion coupled between the proximal portion and the distal portion and defining a body cavity. The body portion is formed of a compressible material that allows the proximal portion to move axially relative to the distal portion. The body cavity, proximal channel, and distal channel form a fluid tight cavity when the proximal portion is engaged with the shaft of the delivery system and the distal portion is engaged with a capsule.

An implantable artificial capsule and a method of implantation are provided. The implantable artificial capsule has a ring with a central opening to accommodate an intraocular lens and at least three haptic arms extending substantially orthogonal from the outer surface of the ring. Each arm has transcleral anchors for sutureless scleral fixation. Upon implantation of the implantable artificial capsule the arms are externalized trans-sclerally and atraumatically. The arms sit subconjunctivally. The implantable artificial capsule does not have any sutures for fixation and is suturelessly implanted in an eye, which is a major advantage as it significantly reduces complications during surgery and recovery.
