Abstract: The present disclosure describes intravascular oxygenation systems and methods with one or more of improved oxygen diffusion flux, improved resistance to bubble formation on the surface of non-porous hollow fibers, and reduced size. The systems and methods include a pneumatic inlet coupled to a pneumatic source that provides a gas containing oxygen at a high pressure. A plurality of hollow fiber membranes (HFM) are in pneumatic communication with the pneumatic inlet to receive the gas containing oxygen and with an outlet to exhaust a partially deoxygenated gas. An electronic controller drives the motor to oscillate the plurality of HFMs to cause a diffusive flux of the gas containing oxygen from the plurality of HFMs into a region of interest of a subject. The electronic controller may drive the motor according to an oscillation pattern, which may include a macro-oscillation with superimposed micro-oscillations.

Abstract: An apparatus is provided for draining aqueous humor from an eye for reducing intraocular pressure. The draining apparatus comprises a tube defining a passage for fluid flow between an inlet end and an outlet end. An outlet assembly contacts the conjunctival layer externally of the eyeball. The outlet assembly comprises a housing in fluid communication with the outlet end of the tube and having an aperture for allowing egress of aqueous humor onto the external ocular surface. A resistive component is disposed in the housing for providing resistance to a flow of aqueous humor. A pair of tabs project outwardly and are adapted to be disposed subconjunctivally for securing the draining apparatus relative to the eyeball.

Abstract: Described herein are compositions and method for autologous adipose tissue grafting. In one embodiment, the composition comprises a recombinant partially ordered polypeptide (Fractomer) or “Fractomer” and adipose tissue from a subject. In one aspect, the Fractomer has the general structure of [(GXGVP)n-?-helix]m, where X can be any amino acid except proline and ?-helix is any polyalanine based ?-helix having about 5 to 50 Alanine residues. In another aspect, the Fractomer has the structure [(GXGVP)n-GX1(A)25X1]m; where X is A or V; X1 is K or D; n is an integer from 10 to 20; and m is an integer from 4 to 8.

Abstract: Intravascular membrane oxygenator catheter systems and methods are disclosed, along with methods of making and using the same. A catheter system includes a catheter shaft having a wall that extends from a proximal end to a distal end along a longitudinal axis to define a lumen, a plurality of hollow fiber membrane loops each having a proximal portion positioned within the lumen of the catheter shaft and a distal portion extending beyond the lumen of the catheter shaft, the hollow fiber membrane loops are nonporous with solid walls; a pneumatic source in pneumatic communication with the hollow fiber membrane loops. The pneumatic source provides a gas containing oxygen at a pressure sufficient to cause a diffusive flux of the gas containing oxygen from an interior of the hollow fiber membrane loops to a fluid exterior to the hollow fiber membrane loops in a region of interest of a subject.

Abstract: The invention provides a modified tissue marking pigment and a method for preparing a modified tissue marking pigment by altering protein adsorption to the surface of the pigment particle, activation of key receptors on important immune cells or altering the pigment particle morphology.

Abstract: Tattoo inks are composed of pigments or dyes combined with a tattoo pigment vehicle which entraps, encases, incorporates, complexes, encapsulates, or is otherwise associated with the pigment to form pigment/vehicle complexes that retain the pigment in the tissue. The vehicle can be chosen so that pigments which alone are unsuitable for tattooing can be used for tattooing and optionally can be retained in the tissue permanently. Alternatively, the vehicle renders the tattoo erasable, wherein the tattoo disappears after imposition of an exogenous energy. Alternatively, the tattoo pigment vehicle renders the tattoo semi-permanent, so that the tattoo spontaneously disappears at a predetermined time.
