Abstract: The present invention relates to a device for changing a course of a vessel, a method of introducing the device, a method of changing a course of a vessel using the device, and a treatment method of brain-nervous system diseases, such as neurovascular compression syndrome, using the device. In treating a neurovascular compression syndrome, the present invention can reduce risks and side effects of the microsurgery (MVD), such as hearing loss or facial paralysis that may occur due to the microsurgery. Further, since an area of a metal surface is small, a risk of in-stent stenosis or thrombus generation is low even in a vessel of the brain having a small diameter, and a degree of vascular compression by its radial force is low, thereby making it possible to minimize intimal hyperplasia.

Abstract: The various embodiments described herein include methods for fabricating thin- film flow diversion apparatuses. In one aspect, a method includes: (1) creating a plurality of trenches using photolithography and deep reactive ion etching on a substrate; (2) depositing a metal sacrificial layer on the substrate; (3) forming a Nitinol layer with a plurality of fenestrations by depositing Nitinol on the metal sacrificial layer; (4) forming a thin-film of Nitinol by removing the metal sacrificial layer; (5) crystallizing the thin-film of Nitinol; and (6) elongating the thin-film of Nitinol.

Abstract: Described herein are intra-oral prostheses that can help replace or augment the function of the native tongue, such as to assist with swallowing. Disclosed prostheses can provide mechanical force, based on the power of mastication, to propel a food bolus into the pharyngeal phase of swallowing. Disclosed prostheses can be used to enhance swallowing rehabilitation as a temporary aid and/or can be used to permanently replace lost tongue functionality. Also disclosed are other anatomical prostheses, such as to provide power for the articulation of dysfunctional extremities, by transforming mechanical force from another nearby functioning muscle group.

Abstract: The present disclosure concerns embodiments of an implantable perfusion device that can be implanted in an injured blood vessel to control bleeding without occluding the vessel. In one specific implementation, the perfusion device can be implanted percutaneously into a patient's descending aorta to control bleeding at the site of a ruptured portion of the aorta (known as torso hemorrhage) while still allowing for the antegrade flow of blood from a location upstream of the ruptured portion of the aorta to a location downstream of the ruptured portion of the aorta. The perfusion device can be left inside the patient as the patient is transported to a medical facility where the injury can be repaired. Following repair of the vessel, the perfusion device can be withdrawn from the patient.

Abstract: A thin film nitinol stent cover is provided that includes a plurality of fenestrations. Each fenestration extends in both longitudinal and transverse dimension, wherein the longitudinal and transverse dimensions are both less than or equal to a critical dimension that inhibits muscle cell migration through the fenestrations.

Abstract: A vascular implant, comprising a sheet comprising thin film nickel titanium (NiTi), wherein the sheet has at least one super-hydrophilic surface having a water contact angle of less than approximately 5 degrees. The sheet is configured to have a compacted form having a first internal diameter and a deployed form having a second internal diameter larger than the first internal diameter. The sheet may be delivered into a blood vessel in the compacted form and expanded to its deployed form at a treatment location within the blood vessel, wherein the stent is configured to expand onto an internal surface of the blood vessel and exert a radial force on said internal surface.

Abstract: The present invention provides novel optically-active aliphatic .beta.-halogen substituted carboxylic acid 4'-(4-alkoxybenzyloxy)biphenyl thioester compounds of the general formula: ##STR1## wherein R represents a straight-chained alkyl radical having C.sub.2 to C.sub.10 carbon atoms and X represents a halogen atom, and a process for the preparation thereof. The novel biphenyl thioester compounds provided according to the present invention are usable as a dopant or a base material for liquid crystal blending, thereby improving the properties of LCD.

Abstract: The present invention provides novel optically-active aliphatic .alpha.-halogen substituted carboxylic acid 4'-(4-alkoxybenzyloxy)biphenyl thioester compounds of the general formula: ##STR1## wherein R represents a n-alkyl radical having C.sub.8 to C.sub.15, carbon atoms, C* represents an asymmetric carbon atom, X represents a halogen atom and R' represents ##STR2## and process for the preparation thereof. The novel biphenyl thioester compounds provided according to the present invention are usable as a dopant or a base material for liquid crystal blending, thereby improving the properties of LCD.
