    摘要: An instrument for positioning a cardiac valve prosthesis in a vessel includes a wire element to slidingly guide the valve prosthesis towards an implantation site and an expandable element coupled to the wire element. The expandable element is expandable in the vessel to position the wire element in association with the implantation site. A method for positioning a cardiac valve prosthesis includes securing a delivery instrument at an appropriate location at the implantation site and delivering the valve prosthesis to the implantation site using the delivery instrument.

    摘要: A distance measuring apparatus includes a light source unit generating reference light for distance measuring, a light receiving device receiving light reflected from an object to be measured, which has received the reference light, a mirror controlling a path of the reference light, and controlling a path of light, reflected from the object to be measured, toward the light receiving device, and a sensor lens focusing the light reflected from the mirror on the light receiving device. The sensor lens includes a lens portion refracting light, a flange portion provided around the circumference of the lens portion and including a coupling portion for fixing the sensor lens, and a light passing portion formed at the lens portion.

    摘要: There is provided an imaging lens including: a transparent substrate; an upper lens disposed on a top of the transparent substrate; and a lower lens disposed on a bottom of the transparent substrate to correspond to the upper lens, wherein one of the upper and lower lenses includes a lens element and a partition wall formed higher than the lens element to surround the lens element. Also, there is provided a method of manufacturing the same. In the imaging lens, the partition wall is replicated together with the lens element on one or both surfaces of the transparent substrate. The partition wall is formed higher than the lens element and has a flat top surface. Therefore, when another lens element is replicated on an opposite surface of the transparent substrate, the previously replicated lens element is prevented from deformation.
