After induction of anesthesia, we inserted a Near-infrared Ray Catheter, a fluorescent ureteral catheter, which allowed us to easily identify and visualize the ureter in real-time. This allowed bowel dissection without concerns of ureteral injury. The operative time for the gastrointestinal part of ...

Here we present a dual-modality imaging system and catheter that uniquely combines IVOCT with diffuse near-infrared spectroscopy (NIRS) in a single dual-modality imaging device for simultaneous acquisition of microstructural and compositional information. As a proof-of-concept demonstration, the device ...
Near-infrared (NIR) imaging is a non-invasive and non-ionizing modality that has been employed to improve the success rate of PIV catheter placement in pediatric patients (e.g., reduce the number of attempts, the number of needle redirections, and the overall time to catheter placement). The...
Progress with the calibration of a 3F near infrared spectroscopy fiber optic catheter for monitoring the plaque PH to detect vulnerable plaque - T. Khan1, B. Soller1, M. Madjid2, S.W. Cassells2, J.T. Willerson2, M. Naghavi2, 1Department of Surgery, University of Massachusetts, North ...
Lipoproteins carry cholesterol through the closed-looped vascular hematological highway of the human body. This cholesterol can embed itself into the
Although the prevalence of cognitive impairment and depression is higher in patients with atrial fibrillation (AF) than in the general population, the mechanism has not been fully examined and impact of catheter ablation (CA) of AF also remains unclear. Recently, the development of near-infrared ...
The present invention relates to a medical device for treating prostate diseases by using near-infrared LEDs (light emitting diodes), and more particularly, to a medical device for
An endovascular near critical fluid based cryoablation catheter for creating an elongated lengthwise-continuous lesion in tissue can comprise an elongated shaft, a flexible distal t
