In one aspect, the present invention provides methods for custom fabrication of IOLs. In some embodiments, such methods call for measuring one or more aberrations of a patient's eye, and determining the profile of at least one surface of an IOL that would ameliorate, and control those aberrations. The surface profile can then be imparted to a surface of a starting lens (or a lens blank) via ablati...

In one aspect, the present invention provides an intraocular lens (IOL) that includes an optic comprising an anterior surface, a posterior surface, and a plurality of diffractive zones disposed on one of those surfaces. The surface having the diffractive zones has a profile characterized by a combination of aspheric and toric components.

A system for visualizing an eye of a patient during corneal surgery includes a processor and a first and second camera in signal communication with the processor. The cameras are positionable for focusing on a cornea positioned for surgery. A first and a second display and optics therefor are in signal communication with the processor and are positionable for viewing through a first and a second e...

Systems and methods that provide magnetically-enhanced delivery of therapeutic agents to selected tissue are disclosed. The systems and methods involve the use of carrier devices and release devices and two different magnetic fields to move magnetic particles into selected tissue. Movement of the magnetic particles (and any associated therapeutic agent) into the tissue may be assisted by both magn...

In various embodiments, a drug-delivery device includes one or more reservoirs that may each contain a therapeutic agent for delivery to a patient.

A method of dispensing product includes determining by a processor if product loaded into a dispenser is authorized for use in the dispenser by identifying a reference indication associated with the product; in response to determination that the product is authorized, dispense a first amount of product; and in response to determination that the sheet product is unauthorized, dispense a second amou...

Devices, methods, and systems facilitate and enable treatment of ischemic stroke. More specifically, a tethered basket-like system operates in conjunction with a microcatheter system, to provide arterial support and capture emboli.

Provided herein are sutures to be used in a procedure applied to tissue, and methods for forming such sutures. A suture can include an elongated suture body and a plurality of heat-contact mediated retainers extending from and along the elongated suture body. The heat-contact mediated retainers can be formed by temporarily contacting the elongated suture body with one or more heated element.

Disclosed are compositions, methods, and kits for joining together non-conjoined lumens in a patient's body including vascular lumens. More particularly, in various aspects, this invention provides compositions, methods, and kits for joining such non-conjoined lumens, including small lumens typically requiring microsurgical technique

A system and method for quickly detaching an implant and for locating the detachment zone of a detachable implant. A sensor determines a sudden change in the local environment as the sensor passes from within a microcatheter to being exposed to the vasculature. The sensor may be a temperature sensor, ultrasonic sensor, pressure sensor or the like. If the detachable implant assembly uses a heater c...

Described herein are methods to occlude structures and malformations with radiopaque hydrogel filaments with delayed controlled rates of expansion permitting the repositioning of the device once inside the structure or malformation. Further described is a method for forming a device for implantation in an animal comprising a difunctional, low molecular weight ethylenically unsaturated shapeable ma...

A system and method of detecting implant detachment within the body of a patient. The activation of the heater coil causes the degradation, melting or reduction of a component that brings the heater coil into or out of electrical contact with another component, or causes the individual loops of the coil to contact each other, thereby resulting in a notable change in resistance in the circuit suppl...
