Abstract: A shape memory polymer (SMP) intraocular lens may have a refractive index above 1.45, a Tg between 10° C. and 60° C., inclusive, de minimis or an absence of glistening, and substantially 100% transmissivity of light in the visible spectrum. The intraocular lens is then rolled at a temperature above Tg of the SMP material. The intraocular device is radially compressed within a die to a diameter of less than or equal to 1.8 mm while maintaining the temperature above Tg. The compressed intraocular lens device may be inserted through an incision less than 2 mm wide in a cornea or sclera or other anatomical structure. The lens can be inserted into the capsular bag, the ciliary sulcus, or other cavity through the incision. The SMP can substantially achieve refractive index values of greater than or equal to 1.45.

Abstract: The present invention provides ocular implants adapted to reside in Schlemm's canal for reducing intraocular pressure of an eye and methods for using the same. In some embodiments the ocular implants comprise a thin rod adapted and configured to extend in a curved volume in Schlemm's canal. The thin rod comprises a plurality of wave-shaped segments such that a sufficient number and amount of wave-shaped segments extend to the inner wall of the trabecular meshwork and to the outer wall of Schlemm's canal thereby keeping Schlemm's canal open.

Abstract: Medical devices for in vivo medical applications are disclosed. The medical devices are constructed of shape memory polymer (SMP) materials capable of assuming a memory shape at physiological temperatures. These medical devices may be used in surgical procedures and in both vascular and non-vascular applications. These SMP medical devices have a post-implantation memory shape that is substantially identical to or slightly larger than the insertion site to adapt to vessel growth or size changes. SMP medical devices may be formed as stents or occlusion devices (i.e., plugs) having a number of different structural features. The SMP medical devices may be formed from a first monomer and a second cross-linking monomer, wherein the weight percentages of the first and second monomers are selected by performing an iterative function to reach a predetermined glass transition temperature (Tg) and a predetermined rubbery modulus to optimize post-implantation memory shape properties of the devices.
