  • Publication number: 20130267887
    Abstract: A small shunt can be placed within the eye to aid in drainage of aqueous humor from the anterior chamber of the eye to a pocket between the conjunctiva and the sclera to be absorbed, or to secrete through the cornea or the sclera external to the eye for glaucoma or ocular hypertension treatment. This drainage can decrease the pressure of the eye and potentially modify the course of advancing glaucomatous optic neuropathy as it relates to eye pressure. The shunt is formed of a shape memory polymer material and deformed into a smaller form factor to reduce trauma to the eye resulting from the insertion of the shunt through the sclera to the anterior chamber. Once in situ, the shunt deploys in response to body heat or other external stimulus and expands to its original, larger form factor to provide a secure friction fit of the shunt within the scleral tissue and to enlarge the lumen of the shunt to allow for aqueous flow.

  • Publication number: 20130218178
    Abstract: Formulations of shape memory polymer (SMP) are integrated with several existing clinically available medical fabrics. The SMP portion of a SMP-integrated fabric can be fabricated in varying thicknesses with the minimum thickness determined by the thickness of the underlying fabric and up to almost any thickness. A large variety of patterns may be formed in SMP-integrated fabrics based upon how the shape memory polymer is integrated into the base fabric. Integration of the SMP with the base fabrics does not alter the shape memory functionality of the SMP. The design tools for controlling activation rate for traditional SMP materials thus apply to SMP-integrated fabrics. SMP-integrated fabrics may also be steam sterilized without loss of shape memory functionality. By using multiple formulations of SMP on a single piece of fabric, a large combination of material properties may be provided within a single SMP-integrated fabric device.

  • Publication number: 20130190868
    Abstract: A modular IOL system including intraocular primary and secondary components, which, when combined, form an intraocular optical correction device, wherein the secondary component is placed on the primary component within the perimeter of the capsulorhexis, thus avoiding the need to touch or otherwise manipulate the capsular bag. The secondary component may be manipulated, removed, and/or exchanged for a different secondary component for correction or modification of the optical result, on an intra-operative or post-operative basis, without the need to remove the primary component and without the need to manipulate the capsular bag. The primary component may have haptics extending therefrom for centration in the capsular bag, and the secondary component may exclude haptics, relying instead on attachment to the primary lens for stability. Such attachment may reside radially inside the perimeter of the capsulorhexis and radially outside the field of view to avoid interference with light transmission.

  • Publication number: 20130149734
    Abstract: A multimodal method for imaging tissue comprising: aligning an excitation light source with at least a portion of the tissue; selecting at least two modalities of image acquisition; imaging the tissue portion with each of the modalities of image acquisition; and constructing a dual mode image using images from each of the modalities of image acquisition. A multimodal system for imaging tissue comprising: an excitation light source or light sources; an optical and alignment system for directing the excitation beam or beams to a sample and receiving an emission beam from the sample; at least one detector for receiving the emission beam from the sample; and a spectral filtering or dispersing device for providing at least two imaging modalities at the at least one detector; and a processor for analyzing the detected emission beam and constructing a dual mode image using images from each of the modalities of image acquisition.

  • Publication number: 20120232648
    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.

  • Publication number: 20120203160
    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.
