Forsythe Technologies Worldwide Inc. has developed a miniature, pressure-sensing tipped catheter for worldwide distribution. At 400 microns in width and 200 microns in thickness, this catheter is unique in its small size and full range of application. All versions have the capability to measure both pressure and temperature in a single sensor. Specially designed models feature in-vivo and in-vitro pressure-sensing catheter tips, while others measure temperature and cardiac output. For clinical and practical purposes, the product allows unlimited analog connectivity and digital networking of up to 50 animals. Device can be used in applications where catheter size has previously limited -- if not restricted -- access to appropriate data collection sites. The firm also has doe wor on small implants to measure blood pressure/ECG
