Abstract: Various methods and devices are provided for allowing multiple surgical instruments to be inserted into sealing elements of a single surgical access device. The sealing elements can be movable along predefined pathways within the device to allow surgical instruments inserted through the sealing elements to be moved laterally, rotationally, angularly, and vertically relative to a central longitudinal axis of the device for ease of manipulation within a patient's body while maintaining insufflation.

Abstract: An idler roll employed in a blown film extrusion line is non turning and a plurality of wear strips are removably attached to the idler roll at circumferentially spaced positions around the idler roll. The wear strips engage blown film passing over the idler roll. The wear strips have reduced coefficients of friction than that of the idler roll, have high wear resistances and the blown film passing over the wear strips cleans and polishes the surface area of the wear strips the film moves across, substantially making the wear strips and the non turning idler roll maintenance free compared with idler rollers with bearings.

Abstract: Presented is an intraocular lens structure fabricated from a material that is hydrophilic, which is sufficiently flexible when hydrated to be rolled or bent into a compact formation for insertion into the eye through a much smaller than usual incision or opening, and which may be implanted either in the capsular bag from which the natural lens has been aspirated, or which may be supported in the posterior chamber sulcus, or in the anterior chamber angle. The lens structure, in one aspect of the invention, is specially packed in a tubular container that retains the hydrated lens structure conformed into a minimum diameter configuration for ease of delivery into the eye, and which, in another aspect of the invention, embodies a package that includes means for delivering the hydrated lens into the eye.

Abstract: Presented is a method and apparatus for custom tinting soft contact lenses in the dispensing office prior to dispensing such lenses to the wearer, or even after they have been dispensed and worn for a time. In the past, contact lenses have been tinted by mass production means by a very limited number of manufacturers. In one aspect, this invention presents a device that can be used by a dispensing optician, optometrist or ophthalmologist to custom tint soft contact lenses to the specification of the wearer while the wearer waits for the lenses to be tinted. In terms of structure, the apparatus comprises a hand-held device into which a soft contact lens may be deposited and sealed and subjected to the chemical reaction of an appropriate dye to tint the contact lens to the requisite color.
