In endovascular catheter interventions, the determination of the three-dimensional (3D)
catheter shape can increase navigation information and help reduce trauma. This study …

Abstract Systems and methods for navigating a catheter and delivering a needle to a desired
anatomic location are provided. The system includes an injection catheter that includes a …

Objective: Ultrasound-guided biopsies and minimally invasive procedures have been used
in numerous medical applications, including catheter guidance. The biggest challenge for …

Navigation of intracardiac catheters by echocardiography is challenging because of the
fundamental limitations of B-mode ultrasonography. We describe a catheter fitted with a …

B‐mode ultrasound imaging guidance of cannulas can be compromised by noise, artifacts,
and echogenicity that is not distinctive from that of surrounding anatomy. We have modified …

背景: 应用颈部深静脉三维可视化模型进行虚拟穿刺仿真, 提高临床深静脉穿刺技能的研究还处
在探索阶段. 目的: 寻求三维虚拟穿刺仿真技术在颈部深静脉穿刺置管中的应用方法 …

Catheters are increasingly used therapeutically and investigatively. With complex usage
comes a need for more accurate intracardiac localization than traditional guidance can …

Objective: To independently visualize a catheter and needle during minimally invasive
surgery in order to aid in precisely guiding them to their intended location. Methods …

Background: Drug or stem cell intramyocardial delivery has been tested using
transendocardial injections navigated by fluoroscopy and NOGA electromechanical …

Percutaneous transendocardial injections of therapeutic agents into the myocardium may
not always be effective. We used an animal model for assessing the efficacy of the injections …
