Abstract: The invention relates to a medical device for positioning a thread in tissue. In particular, the invention relates to a medical device (10) comprising a spiral needle (12), wherein the spiral needle (12) has a spiral-shaped needle body (14) which is formed about a central axis (A) and runs along a spiral path and also has a front end (16) and a rear end (18), wherein at least the front end (16) is integrally formed with the needle body (14), wherein the spiral path has an outer tangential plan (Ta), an inner tangential plane (Ti), an upper side (O) and an opposing underside (U), arid wherein the front end (16) runs in the direction of the spiral path of the needle body (14), and the front end (16) has a tip (22) and a thread-receiving means (24) arranged behind same.

Abstract: The present invention relates to a solar collector or a light collector by means of which light, generally sunlight, can be directed onto an energy conversion unit. In particular, it relates to a light collector (10) that has an optical unit (20) and an energy conversion unit, wherein the energy conversion unit is comprised of a number of conversion cells (12, 14, 16) that are located along a first main axis, wherein the optical unit (20) triggers a refraction of light and surrounds the energy conversion unit at least partially, and the optical unit (20) focuses parallel incident light in a focal area, wherein the focal area has its largest dimension along a second main axis and the second main axis extends along the first main axis.

Abstract: The invention relates to an implant for reducing ocular hypertension. Said implant can be used in particular to prevent and treat glaucomas that are emerging or occur. In particular, the implant is an implant (10) for the Schlemm's canal, which comprises a bridge (20), which has a first end point (22) and a second end point (24) and a first support region (26), a second support region (28), and a connecting piece (30), the bridge (20) extending along a first line (L1) from the first end point (22) to the second end point (24) across the first support region (26), the connecting piece (30), and the second support region (28) and the connecting piece (30) having a first cross-sectional area on average along the first line (L1) and the first support region (26) having a second cross-sectional area on average along the first line (L1) after the implantation, characterized in that the second cross-sectional area is at least 50% larger than the first cross-sectional area.

Abstract: For easy handling at placement of intra ocular lenses (IOLs) for cataract operations, these are equipped with helical haptics of memory materials circumferring the lens. Said haptics adhere to the rim of the lens as long as being cooled down to constriction temperature. On regaining body temperature the haptics expand and fit into the ridges of the eye's capsule sack. Accommodation then is achieved with constriction of the capsule sack by pressure transfer to the rim of the lens to form its shape, in multiplying it with some protrusion towards the pupil.

Abstract: The present invention relates to a surgical needle, which can be used in a medical application for suturing wounds. The present invention more specifically relates to a surgical needle that is connected to a thread and has a tip body, which carries the needle tip, and a needle body, wherein the needle body is helical and has an inner hollow space, and the needle body has a first end, which faces towards the tip body, and the needle body has a second end, which is opposite the first end, and the tip body has a thread receptacle and the thread is guided from the thread receptacle from the first end of the needle body through the hollow space to the second end of the needle body, characterised in that the tip body is formed as a separate component, which is detachably connected to the needle body, and has a tip body, shank piece and connection piece and is rotationally symmetrical about an axis through the needle tip.
