水頭症治療用シャント、神経内視鏡

水頭症の治療では、過剰な脳脊髄液（CSF）を体の他の部位に排出するために、シャントシステムが留置されることが一般的です。脳脊髄液の過剰な蓄積によって上昇した頭蓋内圧を正常範囲に戻し、脳の損傷を防ぎます。

シャント手術に代わる方法として、内視鏡的第三脳室開窓術（ETV）があります。シャントシステムを留置する代わりに、外科的に第三脳室の底に穴を開け、脳脊髄液（CSF）を流し、吸収されるようにする方法です。エースクラップは様々な神経内視鏡システムを提供しています： MINOP®、MINOP® InVent

ミートケ社製重力可変式バルブは、姿勢の変化によって生じるオーバードレナージやアンダードレナージといった合併症を防ぐための機構を備えています。これにより良好な治療効果を発揮し、オーバードレナージの発生を減少させます。[1-4]すべてのミートケ社製シャントバルブは、チタン製で精密に製造されています。また、3テスラ以下の磁場において、開放圧が意図せず変更されないように設計されています。[5]

製品ポートフォリオ

MIETHKE proGAV® 2.0

MIETHKE gravitational valves provide a reliable solution in prevention of overdrainage complications [1, 2] associated with the management of hydrocephalus.proGAV® 2.0 represents the latest development by refining our existing proGAV® technology to better meet the needs of our customers and their patients.proGAV® 2.0 offers the reliability of our existing technology with a new tactile “Feedback” mechanism and “Soft-Touch” instrumentation. The adjustable unit is equipped with a special valve surface: By using slight pressure with your finger, the “Active-Lock” mechanism of the valve is released and a tactile feedback is received.The combination of the refined proGAV® technology and “Soft-Touch” instrumentation provides comfort for patients and security against inadvertent readjustment caused by magnetic fields up to 3 Tesla [3].With the new proGAV® 2.0 Compass the opening pressure of the adjustable unit can be identified quickly, without having to expose the patient to X-ray.Indication:Treatment of Hydrocephalus

MIETHKE proSA®

The MIETHKE proSA® Shunt System represents the first generation of adjustable gravitational valves that allow postoperative adaptation to the individual needs of the patient for the upright body position. [1,2]It offers effective protection against overdrainage through an individually and continuously adjustable large opening pressure range of 0-40 cmH2O [3,4]The patented verification and adjustment instruments enable a simple, quick and uncomplicated adjustment of the pressure level without having to perform X-rays that are stressful for the patient. [3,4,5,6]Indication:Treatment of Hydrocephalus

MIETHKE miniNAV®

The MIETHKE miniNAV® was developed as a compact differential pressure valve which, due to its small design, is particularly suitable for the treatment of pediatric hydrocephalus, especially in premature and newborn infants.[1] Another area of application is hydrocephalus in bedridden patients.The valve is made of titanium, a material that allows excellent precision, stability and biocompatibility.Indication:Treatment of Hydrocephalus

MINOP®

MINOP® is an intraventricular neuroendosopic system designed primarily for the treatment of intraventricular indications such as occlusive hydrocephalus and the removal of tumors and cysts.BenefitsModular, sophisticated designTrocar with rounded tip for less traumatic insertion into the brainLarge depth scale for safer positioning and better control inside the ventriclesOptimized optical components leading to an enlarged image area, higher image quality, brightness and contrastAngled design for enhanced instrument maneuverabilityFeatures:Trocar withAttachment for connection of peripheral devicesAdditional single obturator for the working channel for insertion under visual control, with the 0° endoscopeFull HD compatible endoscopes with different directions of view (0° and 30°)Special micro instrumentsDetachable tube shaft instruments with tactile feedback and rotatable instrument tip for improved control and enhanced handling and precisionFlexible instruments for bi-instrumental working (with both hands)Monopolar and bipolar electrodesSingle-use suction cannulasAdditional information:Single-use introducer for preserving the brain in case of repeated insertion and withdrawal of the endoscopic system during an operationAdapter for fixation to Aesculap® holding devicesDedicated baskets for sterilization and storage
