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.

Described is an intravascular device including a stent structure and at least one annular band. The stent structure may be sized for insertion into a blood vessel and configured to expand to contact the wall of a blood vessel after insertion therein. The annular band is configured to change in diameter in response to an applied electrical field. A method of maintaining and accelerating pulsatile blood flow includes positioning an annular band within a blood vessel, and causing the annular band to expand and contract in response to an electrical field.

In some instances, the disclosure provides performing a breast implant procedure using a permanent expandable prosthetic breast implant. The method comprises subsequent to placing the permanent expandable prosthetic breast implant within a breast region of an individual, injecting a polymer into the permanent expandable prosthetic breast implant, and changing a viscosity of the polymer within the permanent expandable prosthetic breast implant using a chemical reaction.

An volume filling device for treatment of obesity is placed outside the stomach wall of the patient to reduce the inner volume of the stomach, thereby affecting the patient's appetite. By providing the volume filling device outside the stomach wall, contact with stomach acids is avoided, thereby increasing the life of the device.

According to an aspect, an inflatable penile prosthesis includes a fluid reservoir configured to hold fluid, an inflatable member, and an electronic pump assembly configured to transfer the fluid between the fluid reservoir and the inflatable member. The electronic pump assembly includes a pump, an active valve, and a controller configured to receive an external signal to activate an inflation cycle and control at least one of the pump or the active valve to transfer the fluid to the inflatable member. The controller includes a printed circuit board assembly. The printed circuit board assembly includes a microprocessor or a state machine.

According to an aspect, an active valve for an implantable device includes a base plate defining an opening, a piezo element, a diaphragm actuator coupled to the piezo element, and a protrusion coupled to the diaphragm actuator. The diaphragm actuator, in response to the piezo element being activated, is configured to move the protrusion into the opening in a first direction until the protrusion contacts a portion of the base plate.

An implant system for restoring and improving physiological intracardiac vortical flow in a human heart is provided including a dual force transducting annular implant comprising laterally extending struts transitioning into annular structural members for positioning on the atrial side of the valve annulus; an anchoring system comprising a therapeutic base plate assembly attachable to the apex of the heart; and a tether assembly comprising a tether connected between the implant and the therapeutic base plate assembly.

Exemplary light control devices and methods provide a regional variation of visual information and sampling (“V-VIS”) of an ocular field of view that improves or stabilizes vision, ameliorates a visual symptom, reduces the rate of vision loss, or reduces the progression of an ophthalmic or neurologic condition, disease, injury or disorder. The V-VIS devices and methods generate a moving aperture effect anterior to a retina that samples and delivers to the retina environmental light from an ocular field of view at a sampling rate between 50 hertz and 50 kilohertz. Certain of these V-VIS devices and methods may be combined with augmented or virtual reality, vision measurement, vision monitoring, or other therapies including, but not limited to, pharmacological, gene, retinal replacement and stem cell therapies.

A method and system of traversing a device through an accommodating conduit to reach a target area within the accommodating conduit can include varying an amount of elasticity of the device or an amount of torsion moment of the device applied to the accommodating conduit or varying both to minimize bending forces as the device traverses the accommodating conduit. The method or system upon reaching the target area within the accommodating conduit, can further include varying the elasticity or the torsion moment of the device or varying both to cause the device to stiffen. Other embodiments are disclosed.

The present invention relates to an artificial valve for implantation in a mammal body, in or adjacent to a mammal blood vessel, the artificial valve comprising a casing and an opening and closing mechanism, with at least part of said opening and closing mechanism being a first moving part adapted to make an opening and a closing movement relative to the casing, said movements comprising movements to assume an open and a closed position for opening and closing, respectively, of the blood flow through said blood vessel, as well as positions between said open and closed positions.
