Journal ArticleDOI
Optical Fluorescence and Its Application to an Intravascular Blood Gas Monitoring System
John L. Gehrich,Dietrich W. Lübbers,Norbert Opitz,Douglas R. Hansmann,William W. Miller,James K. Tusa,Maseo Yafuso +6 more
TL;DR: An optical fluorescence based intravascular blood gas monitoring system has been developed which is particularly suited for the critical care and surgical settings and which has a sensor probe that can be introduced into the patient via a radial artery catheter.

Ultrasound catheter with cavitation promoting surface
TL;DR: In this paper, a method of applying ultrasonic energy to a treatment site within a patient's vasculature comprises positioning an ultrasound radiating member at the treatment site and activating it to produce pulses at a cycle period T ≤ 1 second.
Journal ArticleDOI
Minimally invasive evacuation of spontaneous intracerebral hemorrhage using sonothrombolysis.
David W. Newell,M. Mohsin Shah,Robert L. Wilcox,Douglas R. Hansmann,Erik Melnychuk,John Muschelli,Daniel F. Hanley +6 more
TL;DR: Lysis and drainage of spontaneous ICH and IVH with a reduction in mass effect can be accomplished rapidly and safely through sonothrombolysis using stereotactically delivered drainage and ultrasound catheters via a bur hole.
Patent
Treatment of vascular occlusions using ultrasonic energy and microbubbles
TL;DR: In this article, a method of treating a vascular occlusion located at a treatment site within a patient's vasculature comprises positioning an ultrasound catheter at the treatment site.
Journal ArticleDOI

TL;DR: The accuracy of the retracted probe was evaluated in 4 subjects who breathed varying fractions of inspired oxygen and carbon dioxide and the mean in vivo 90% response times for step changes in inspired gas were 2.64, 3.88, and 2.60 minutes, respectively, for pHi, PiCO2, and PiO2.
