Endovascular laser detachment of platinum alloy microcoils: Principle and initial experimental experience

The aim of the investigation was the technical realization and approval of a new method for insertion and detachment of platinum alloy microcoils and other vascular implants via standard microcatheters. Flexible lightconducting fibers, 105 microns in diameter were connected to platinum alloy microcoils. It was examined whether an insertion wire, a lightconducting fiber and a platinum alloy microcoil could be advanced through a Tracker-18 (Target) microcatheter. The detachment of the attached coil from the lightconducting fiber was investigated. Platinum alloy microcoils can be attached to available lightconducting fibers in a reliable and reproduceable manner. Together with the fiber they can be advanced via a Tracker-18 microcatheter. Only extremely tortuous vessels may increase the friction to critical values. A Ho-YAG laser source was used. This allowed the instantaneous detachment of microcoils from laser fibers. In contrast to electrolytical detachment, no foreign substances are released to the blood stream. The detachment does not require waiting time and does not activate thrombus formation. Due to specific technical features, injuries of the vessel wall are avoided. After further miniaturization and adaption of the lightconducting fibers to the required characteristics, laster detachment may have the potential to replace current methods such as electrolytical and mechanical coil detachment.

Herausforderungen für Kompetenzentwicklung in schnell wachsenden innovativen kleinen und mittleren Unternehmen

Dass Kompetenzentwicklung als Innovationstreiber gelten kann, stellt einen disziplinenubergreifenden Konsens dar. Investitionen in die „Human Side of Innovation“ werden jedoch in der Praxis immer wieder vernachlassigt. Dieses Spannungsfeld wird in diesem Beitrag mit Fokus auf schnell wachsende kleine und mittlere Unternehmen (KMU) analysiert: In der kritischen Wachstumsphase ergeben sich typische Kompetenzentwicklungsaufgaben wie die Rekrutierung und Integration neuer Talente, eine Uberlastung von Schlusselpersonen, die Gestaltung von Kommunikationswegen und Schnittstellenprobleme zwischen verschiedenen Tatigkeitsbereichen. Am empirischen Fallbeispiel eines Medizintechnikunternehmens werden Losungsansatze aufgezeigt. Um eine Etablierung als innovatives Unternehmen zu unterstutzen, ist ein ganzheitlicher Ansatz zu entwickeln, der vom schnellen Wachstum zu einem Pfad der kontinuierlichen Verbesserung uberleitet.
