Abstract:
PURPOSE: A separable micro-coil assembly is provided, which can be accurately inserted into patient's brain aneurysm occurrence part. CONSTITUTION: A separable micro-coil assembly comprises: a first coil(100) interrupting the inflow of the blood flow; a second coil(200) in which one end is inserted into one end of the inner cavity of the first coil; an extension resistance core which is arranged in order to pass through the inner cavity of the first coil and inner cavity of the second coil; and a carrying wire(400) which is connected to the other end part of the second coil and transfers the first coil to the brain aneurysm occurrence part.
Abstract:
PURPOSE: A micro-coil assembly is provided to guide a micro-coil unit to be accurately inserted the cerebral artery of a patient by combining a micro-coil unit and a coil pushing unit through a stitching fiber. CONSTITUTION: A micro coil assembly(100) includes a micro coil unit(110), a coil pusher unit(120), a string(130), and a tensile wire(140). The micro coil unit is inserted into the cerebral artery of a patient, and it induces a blood clot and prevents the inflow of blood. The coil pusher unit transfers the micro coil unit to the cerebral artery. The micro coil unit and coil pusher unit are connected through a stitching fiber. The stitching fiber is broken up by a tensile wire, separating the coil pusher unit from the micro coil unit each other.
Abstract:
PURPOSE: A micro coil assembly is provided to insert a micro coil unit accurately in aneurysm or other vascular malformation generating parts of a patient by inserting the micro coil unit conveniently and accurately. CONSTITUTION: A micro coil unit(110) blocks an inflow of blood by inducing blood clot with inserting the micro coil unit into an aneurysm or other vascular malformation generating parts of a patient. A coil pusher unit(120) is placed adjacently to the micro coil unit, and transports the micro coil unit to an occurrence part of a patient. A tensile wire(130) is placed portably at the coil pusher unit. A binding strap is connected to the micro coil unit, and the tensile wire. Binding strap cutting units cut the binding strap in the movement to a cutting point by placing adjacently to the coil pusher unit for the movement of one part between a setting position and a cutting position.
