Patent number: 10716482Abstract: Catheter systems and methods for determining blood flow rates based on temperature measurements by thermodilution. The catheter may include a fluid lumen defined between inner and outer tubular members for delivering an indicator fluid, and a guidewire lumen defined by the inner tubular member. The catheter may include fluid infusion openings at the distal end region of the outer tubular member configured to permit the indicator fluid to exit the catheter from the fluid lumen, and a fluid hole located at the distal end region of the inner tubular member configured to permit the indicator fluid to pass from the fluid lumen into the guidewire lumen. A temperature sensor positioned on a guidewire may be positioned within the guidewire lumen to measure the temperature of the indicator fluid entering the guidewire lumen through the fluid hole. A blood flow rate may be calculated based on the measured temperature.Type: GrantFiled: April 24, 2014Date of Patent: July 21, 2020Assignee: HEXACATHInventors: James M. Anderson, Jan Weber, Steven J Koch, Timothy S. Girton, Nico H J Pijls, Bernard De Bruyne

Patent number: 8114151Abstract: A stent can include a tubular body, a plurality of circumferential serpentine bands, a plurality of connectors extending between immediately adjacent serpentine bands, and a plurality of tabs. The plurality of tabs include peak tabs and trough tabs. Each peak tab and each trough tab have a first end and a second end wherein only the first end is engaged to a serpentine band, each peak tab extends substantially parallel to the longitudinal axis from a peak on a serpentine band toward a peak on an immediately distal serpentine band. Each trough tab extends substantially parallel to the longitudinal axis from a trough on a serpentine band toward a trough on an immediately proximal serpentine band. Each serpentine band defines a plurality of holes and each tab defines a plurality of holes. The holes are constructed and arranged to contain a therapeutic agent.Type: GrantFiled: May 8, 2008Date of Patent: February 14, 2012Assignee: Boston Scientific Scimed, Inc.Inventors: Gordon J.

Publication number: 20110066227Abstract: A stent having one or more beneficial agents which enhance the healing effect of the stent. The agent is positioned within a reservoir. The reservoir dynamically releases the agent when the stent is expanded. The reservoir makes use of various changes in stent shape during expansion to assure proper release of the agent. Agent release can be modulated at various points along the stent and with various rates of release. The reservoirs can also be cooperatively combined with features that enhance stent flexibility, structural integrity, and which prevent recoil.Type: ApplicationFiled: September 17, 2009Publication date: March 17, 2011Applicant: BOSTON SCIENTIFIC SCIMED, INC.Inventors: Michael P.
