Abstract
Det beskrives en medisinsk innretning, særlig en kirurgisk innretning som vanligvis føres inn gjennom et intravaskulært kateter. Innretningen kan benyttes på mange måter. Den kan for eksempel benyttes for å åpne en passasje nær en trombe for derved å tillate at så vel blod som medikament kan gå forbi klumpen. Innretningen kan benyttes for å gjennomtrenge og fjerne tromben. Slike tromber finnes ofte i buktet vaskulatur. Innretningen har flere seksjoner. Innretningen (216) er et kjerneelement (202), vanligvis en kjemetråd. Rundt kjerneelementets (202) distale ende er det anordnet en sammenklappbar, men fortrinnsvis selvekspanderende buranordning (206). Buranordningen (206) er fortrinnsvis radio-opak. Burets (206) proksimale ende er vanligvis festet til en aktuator (212) på en slik måte at det muliggjøres en ekspansjon av buret (206) etter plasseringen. Buranordningen (206) kan ha en i hovedsaken konisk distal eller "etterslepende" del når anordningen er ekspandert, og kan også ha en proksimal seksjon. Buranordningen (206) kan benyttes for oppsamling av emboli eller for forskyving av disse for gjenoppretting av en blodstrømning. Den proksimale seksjon kan tjene ulike formål, eksempelvis for sentrering av samleanordningen i blodkaret eller for oppsamling av større mengder av klumpen, eller som kunstig passasje for en fluidumstrømning.A medical device is described, in particular a surgical device which is usually inserted through an intravascular catheter. The device can be used in many ways. It can, for example, be used to open a passage near a thrombus, thereby allowing blood as well as drug to pass through the lump. The device can be used to penetrate and remove the thrombus. Such thrombi are often found in curved vasculature. The facility has several sections. The device (216) is a core element (202), usually a core wire. Around the distal end of the core element (202) is provided a collapsible but preferably self-expanding cage device (206). The cage device (206) is preferably radio-opaque. The proximal end of the cage (206) is usually attached to an actuator (212) in such a way as to allow for expansion of the cage (206) after placement. The cage device (206) may have a substantially conical distal or "lagging" portion when the device is expanded, and may also have a proximal section. The cage device (206) can be used for collecting emboli or for displacing them to restore blood flow. The proximal section may serve various purposes, for example for centering the collecting device in the blood vessel or for collecting larger amounts of the lump, or as artificial passage for a fluid flow.
