Trackability of a high-strength thromboresistant hydrogel catheter: An In vitro analysis comparing venous catheter forces in a simulated use pathway.

As the need for vascular access devices (VADs) continues to increase, so does the need for innovative designs and materials that can improve placement and optimize patient outcomes. Commercially available peripherally inserted central venous catheters (PICCs) are in high demand due to their ease of use and low cost. However, they are constructed of materials that can contribute to vascular injury and result in complications such as clotting, catheter failure, and infection.

Robot-assisted ultrasound imaging: overview and development of a parallel telerobotic system.

Ultrasound imaging is frequently used in medicine. The quality of ultrasound images is often dependent on the skill of the sonographer. Several researchers have proposed robotic systems to aid in ultrasound image acquisition.

PATIENT: Physical Anatomical Trainer Instrumented for Education and Non-Subjective Testing.

The PATIENT manikin (Physical Anatomical Trainer Instrumented for Education and Non-subjective Testing) is designed with the conflicting needs of a highly modular system for ultimate scenario flexibility and cost containment, and a highly realistic system. PATIENT provides a unique combination of capital and disposable components, with each organ treated as a limited-reuse component. The organs contain unobtrusive instrumentation which informs the PATIENT control unit of the organ status.

Cardiac ablation catheter guidance by means of a single equivalent moving dipole inverse algorithm.

Background: We developed and evaluated a novel system for guiding radiofrequency catheter ablation therapy of ventricular tachycardia. This guidance system employs an inverse solution guidance algorithm (ISGA) using a single equivalent moving dipole (SEMD) localization method. The method and system were evaluated in both a saline tank phantom model and in vivo animal (swine) experiments.
