DESCRIPTION (provided by applicant): Catheter localization is a key technology for advancing minimally invasive surgical procedures. Localization technology provides an alternative to imaging in many catheter procedures and is presently applied in several specialties including neurosurgery, electrophysiology, and other surgical fields. This project will develop enabling technology that will allow localization to be applied to small catheters such as microcatheters and guidewires, and will allow localization to be integrated into catheters having limited space due to the addition of auxiliary sensors. Additionally, this technology enables guidewire localization information from points on the wire proximal to the wire tip, thus alerting the physician to wire prolapse. In phase I, Koronis Biomedical Technologies will design and fabricate a new ultra-miniature sensor for micro-catheter localization using thin-film Giant MagnetoResistive (GMR) technology. In phase II a prototype catheter localization system will be developed and evaluated. PUBLIC HEALTH RELEVANCE: Thin film Giant MagnetoResistive (GMR) sensors can be applied to extremely small micro- catheters and guidewires. This enabling technology provides an alternative to visualization during catheter procedures including neurosurgery, electrophysiology and other surgical fields.

描述（由申请人提供）：导管定位是推进微创手术程序的关键技术。本地化技术为许多导管程序提供了成像的替代方法，目前已应用于包括神经外科，电生理学和其他手术领域在内的多个专业中。该项目将开发促进技术，该技术将允许将定位应用于小导管，例如微心会员和指南，并允许由于添加辅助传感器而将定位集成到具有有限空间的导管中。此外，该技术可以从导线近端的点上的点启用导线定位信息，从而提醒医师脱垂。在第一阶段，Koronis Biomedical Technologies将使用薄膜巨型磁层（GMR）技术设计和制造一种新的超细量传感器，用于微型导管定位。在II期中，将开发和评估原型导管定位系统。公共卫生相关性：薄膜巨磁磁性（GMR）传感器可以应用于极小的微导管和指南。这种启示技术为导管过程中的可视化提供了替代方法，包括神经外科手术，电生理学和其他手术领域。
