ADDITIVE MANUFACTURING INSIDE THE HUMAN EYE
20200297480 · 2020-09-24 ·

Additive manufacturing techniques are used to form an artificial intra-ocular lens (IOL) directly inside the human eye. Small openings are formed in the cornea and lens capsule of the eye, and the crystalline lens is broken up and removed through the openings; then, a material is injected into the lens capsule through the openings, and the focal spot of a pulse laser beam is scanned in a defined pattern in the lens capsule, to transform the material in the vicinity of the lase focal spot to form the IOL in a layer-by-layer manner. In one embodiment, stereolithography techniques are used where a pulse UV laser source is used to photosolidify a photopolymer resin. The liquefied resin is injected into the eye through the openings, after which only part of the resin, having the shape of the desired IOL, is selectively cured with the UV laser beam, via progressive layer formation.

The invention relates to a suction stent for introduction into a hollow organ of the human or animal body, preferably into the gastrointestinal tract, in particular the intestine, comprising a tubular hollow body which is open in the longitudinal direction and made of biocompatible material, the tubular hollow body having a fixed diameter at least in its central portion; and a porous shapeable material, preferably a sponge material, which is biocompatible and shapeable in the radial direction, the porous shapeable material radially sheathing the tubular hollow body at least in a section of the tubular hollow body. Further, the invention relates to a method for sealing a leakage, especially an anastomosis, of the hollow organ.

Selectively Expanding Spine Cage With Enhanced Bone Graft Infusion
20200289289 · 2020-09-17 ·

A selectively expanding spine cage has a minimized cross section in its unexpanded state that is smaller than the diameter of the neuroforamen through which it passes in the distracted spine. The cage conformably engages between the endplates of the adjacent vertebrae to effectively distract the anterior disc space, stabilize the motion segments and eliminate pathologic spine motion. Expanding selectively (anteriorly, along the vertical axis of the spine) rather than uniformly, the cage height increases and holds the vertebrae with fixation forces greater than adjacent bone and soft tissue failure forces in natural lordosis. Stability is thus achieved immediately, enabling patient function by eliminating painful motion. The cage shape intends to rest proximate to the anterior column cortices securing the desired spread and fixation, allowing for bone graft in, around, and through the implant for arthrodesis whereas for arthroplasty it fixes to endpoints but cushions the spine naturally.

A stent graft system includes a stent graft, a radially expandable scaffold, and an inflatable fill structure. The stent graft includes a body portion with a plurality of pleated sections that are configured to be extended from a telescopically compressed state to a longitudinally extended state. The radially expandable scaffold is attached to a top of the body portion, and has one or more fixation elements for penetrating into an aortic wall. The inflatable fill structure is attached at a top of the body portion and is configured to expand in a longitudinal direction as the body portion is extended in the longitudinal direction. The inflatable fill structure is also configured to expand in a radial direction to contact an inner surface of a blood vessel.
