Abstract:
Disclosed is a vascular stent which is inserted inside a blood vessel. The disclosed vascular stent comprises: a first coating film comprising a restenosis inhibiting drug provided on the outside surface of the stent strut; and a second coating film comprising an internal-capsule cellularization promoting drug provided on the inside surface of the stent strut. In this way, restenosis and thrombosis can be prevented from occurring inside the stent.
Abstract:
The present invention discloses an air-injection type tool for scrubbing off the dirt on a body including: an air-retaining body 2 formed of an elastic material expandable in an air-injection manner, the air-retaining body 2 having a scrubbing towel 40 encompassed on the external surface thereof; a disc-like support body 4 disposed at the inside of the air-retaining body 2 and having a cylindrical coupling protrusion 6 formed at the top central portion thereof, the cylindrical coupling protrusion 6 having a piston A reciprocated therein such that the air generated by the reciprocating motion of the piston A is sent to the air-retaining body 2; and a cover body 12 adapted to be pressurized by a handle 18 screw-coupled with the coupling protrusion 6 of the support body 4 thus to come into close contact with the support body 4 such that the air-retaining body 2 is kept airtight.
Abstract:
The invention relates to an electro-optrode neural interface, comprising an optical fiber which is elongated so as to be insertable into a body, and which is located at a core portion so as to form an optical electrode portion, and a liquid crystal polymer (LCP) sample encircling the optical fiber. The LCP sample has an adhesive sheet, and an LCP electrode layer encircling the adhesive sheet, wherein the adhesive sheet and the LCP electrode layer are coupled to each other. The electro-optrode neutral interface is formed by combining, into a single unit, an electrical interface in which an electrode for stimulating deep brain or measuring neural signals from deep brain is arranged in a liquid crystal polymer and an optical interface such as an optical fiber, a waveguide and an endoscope. The electro-optrode interface of the present invention may enable an electro-optrode to be inserted into a body while electrically or optically monitoring the position of the electro-optrode in real time, and may be mass produced.
Abstract:
The invention relates to a transmitter for transmitting data in bio-implantable medical devices, comprising: an activation unit which transmits, to a receiver, a predetermined number of frame bits which indicate the start of data transmission so as to activate the receiver; a preamble state notification unit which transmits, at the state where the receiver is activated or during data transmission to the receiver, a preamble data signal for turning the receiver into a preamble state; and a synchronization unit which transmits synchronization data for synchronization between the transmitter and the receiver in the preamble state.
Abstract:
The present invention relates to a method for detecting a trace of a target material by mixing a linker and a spacer in a proper ratio in a carbon nanotube-based biosensor and then immobilizing the mixture on the surface of the carbon nanotube. Since the method can detect a specific material on a femtomol level, detection limits of conventional carbon nanotube transistor sensors can be substantially lowered, so a trace of a target material can be detected. Therefore, the method can be used as an innovative analysis method used in a medical sensor for disease diagnosis or an environmental sensor.
