Embodiments described herein address the need for improved catheter devices for delivery, repositioning and/or percutaneous retrieval of the percutaneously implanted heart valves. One embodiment employs a plurality of spring-loaded arms releasably engaged with a stent frame for controlling expansion for valve deployment. Another embodiment employs a plurality of filaments passing through a distal end of a pusher sleeve and apertures in a self-expandable stent frame to control its state of deployment. With additional features, lateral positioning of the stent frame may also be controlled. Yet another embodiment includes plurality of outwardly biased arms held to complimentary stent frame features by overlying sheath segments. Still another embodiment integrates a visualization system in the subject delivery system. Variations on hardware and methods associated with the use of these embodiments are contemplated in addition to those shown and described

A system, method, and apparatus are provided for designing and evaluating intraocular lenses for a large field of view that generate a first eye model from data that includes constant and customized values, including customized values of a first intraocular lens. A simulated outcome is provided by the first intraocular lens in at least one modeled eye. A second eye model is generated wherein a second intraocular lens is substituted for the first intraocular lens. An outcome provided by the second intraocular lens is simulated in at least one modeled eye. Outcomes of the first and second intraocular lenses are compared.

A temporary space-filling penile implant device for penile surgery includes a body portion, an end portion attached to the body portion, and a cover surrounding the end portion and at least a portion of the body portion. The temporary space-filling penile implant may be configured for insertion into either corpora cavernosa of a penis or into interior tissue of a neophallus, during an inter-procedure time period that occurs between two surgical procedures performed on the penis or the neophallus.

Devices and methods are provided for supporting a subject's heart, e.g., to support the left and/or right ventricles of the heart, e.g., to prevent and/or treat heart failure. In one example, the device includes a sleeve configured to be implanted over a region of the subject's heart including a lattice formed on a surface of the sleeve. The sleeve may be positioned and permanently implanted over a desired region of the subject's heart to provide passive support to ventricular tissue of the heart.

A reusable surgical implement is provided that is formed of a core positioned within an enclosure. The core is formed of a suitable flexible material to enable the implement, which can be any suitable device such as a reusable surgical trial implant, rod template or flex driver, among others, to be bent to conform to the desired shape for an actual implant to be placed in the location of the implement. The material forming the enclosure is also flexible to accommodate the flexing of the core, and is biologically inert to enable the implement to be sterilized after use for use in subsequent surgical procedures.

A mold, apparatus, and method for providing a realistic simulation of a breast augmentation. The mold is an onlay mold that is additively manufactured with a negative mold of a topography of a native breast on one side and an ideal augmented topography on the opposite side. The mold is adherable to a torso of a patient over a native breast to illustrate a real look and feel of a completed augmentation. The mold may also be positioned within a pocketed brassiere to provide the simulation. The mold is generated from a three dimensional image taken of the patient's torso and breast.
