ANALYSIS OF BEATING HEART INTRACARDIAC SURGERY

这个子项目是许多研究子项目中利用 资源由NIH/NCRR资助的中心拨款提供。子项目和 调查员(PI)可能从NIH的另一个来源获得了主要资金， 并因此可以在其他清晰的条目中表示。列出的机构是 该中心不一定是调查人员的机构。 该项目的目标是通过机器人仪器控制和软组织力学开发访问设备、成像技术和安全措施，以实现心脏不停跳心内外科手术。具体地说，在软组织力学领域，我们的目标是表征正常和病变心房的力学特性，以更好地了解这些组织对心脏不停跳下经心房手术的耐受性。McCulloch教授开发的猪心房解剖数据库将作为我们从宏观和微观解剖特征方面描述心房的基础。此外，他的团队开发的连续性建模软件以及在使用该工具时提供的支持将使我们能够开发该模型并验证我们对软组织属性的物理测量。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. The goals of this project are to develop access devices, imaging techniques and safety measures through robotic instrument control and soft tissue mechanics to enable beating heart intracardiac surgical procedures. Specifically, in the area of soft tissue mechanics, we aim to characterize the mechanical properties of both normal and diseased atria to better understand the tolerance of these tissues to trans-atrial surgery inside a beating heart. The database of porcine atrial anatomy developed by Prof. McCulloch will serve as a basis for our characterization of the atria in terms of both macroscopic and microscopic anatomic features. Furthermore, the Continuity modeling software developed by his group and the support afforded in the use of this tool will allow us to develop this model and validate our physical measurements of the soft tissue properties.
