Patent number: 7481774Abstract: The disclosed embodiments present improved catheters with physiological sensors. In one embodiment, the catheter includes, generally, a pressure transducer/electronics assembly connected to a pressure transmission catheter. The pressure transmission catheter includes a hollow tube made from a low compliance material. The distal end of the hollow tube is filled with a gel-like material or plug which acts as a barrier between the catheter liquid and the target fluid. The hollow tube is partially filled with a low viscosity liquid and is in fluid communication with the gel-like material and the pressure transducer. The pressure of the target fluid is transmitted to the liquid in the hollow tube through the gel-like material and/or the wall of the distal tip and is fluidically transmitted to the pressure transducer. The pressure transmission catheter may be inserted into a vessel lumen or into a lumen of a therapeutic or diagnostic catheter for biomedical applications.Type: GrantFiled: April 22, 2003Date of Patent: January 27, 2009Assignee: Transoma Medical, Inc.Inventors: Brian P. Brockway, Lynn M. Zwiers, Perry A. Mills, Mark J. Drexler

Patent number: 7464602Abstract: Methods and apparatus for sensing pressure are disclosed. One disclosed pressure measuring device comprises a pressure transmission catheter including a stem portion and a sheath fixed to the stem portion. The disclosed sheath comprises a wall defining a cavity that is in fluid communication with a stem lumen defined by the stem portion. The disclosed sheath has a first transverse extent and a second transverse extent that is different from the first transverse extent.Type: GrantFiled: June 30, 2006Date of Patent: December 16, 2008Assignee: Transoma Medical, Inc.Inventors: Lynn M. Zwiers, Gregg Lichtscheidl, Eric Rudie

Patent number: 7425200Abstract: An implantable sensor device, such as a pressure monitor, is implanted in the left ventricle (LV), in other heart chambers, or elsewhere, from which it wirelessly communicates pressure information to a remote communication device. The sensor device can be implanted using a placement catheter, an endoscope, or a laparoscope. The device can be secured entirely within the LV or heart wall, such as by using a corkscrew, a helical anchor, a harpoon, a threaded member, a hook, a barb, a fastener, a suture, or a mesh or coating for receiving fibrous tissue growth. The implantable sensor device provides less invasive chronic measurements of left ventricular blood pressure or other physical parameters. The wireless communication techniques include radio-telemetry, inductive coupling, passive transponders, and using the body as a conductor (referred to as “intracorporeal conductive communication” or a “personal area network”). Data from the receiver is downloadable into a computer for analysis or display.Type: GrantFiled: May 15, 2002Date of Patent: September 16, 2008Assignee: Transoma Medical, Inc.Inventors: Brian P. Brockway, Perry Alton Mills, Lynn M. Zwiers

Publication number: 20080039897Abstract: A pressure sensing device includes a body portion, a pressure transmitting port, and an electrical lead. The body portion includes transducing electronics within a housing that is shaped about a longitudinal axis. The housing has a coating thereon that promotes tissue growth to anchor the housing within a ventricular septum. The pressure transmitting port is located at a distal longitudinal end of the body portion such that a ventricle pressure being sensed is transmitted through the port and to the transducing electronics when the body portion is anchored in the ventricular septum. The electrical lead is connected to the transducing electronics and exits from a proximal longitudinal end of the body portion.Type: ApplicationFiled: August 9, 2007Publication date: February 14, 2008Inventors: Stanley E. Kluge, Scott Thomas Mazar, Eric N. Rudie, Lynn M. Zwiers
