Patent number: 8896324Abstract: A method for providing an in-vivo assessment of relative movement of an implant that is positioned in a living being is provided wherein a first assembly and a second assembly are positioned within the living being. The first assembly includes a passive electrical resonant circuit that is configured to be selectively electromagnetically coupled to an ex-vivo source of RF energy and, in response to the electromagnetic coupling, generates an output signal characterized by a frequency that is dependent upon a distance between the first assembly and the second assembly at the time of the electromagnetic coupling.Type: GrantFiled: September 26, 2011Date of Patent: November 25, 2014Assignee: CardioMEMS, Inc.Inventors: Jason Kroh, Florent Cros, Christophe Courcimault

Publication number: 20140084943Abstract: This application relates to an apparatus and system for sensing strain on a portion of an implant positioned in a living being. In one aspect, the apparatus has at least one sensor assembly that can be mountable thereon a portion of the implant and that has a passive electrical resonant circuit that can be configured to be selectively electromagnetically coupled to an ex-vivo source of RF energy. Each sensor assembly, in response to the electromagnetic coupling, can be configured to generate an output signal characterized by a frequency that is dependent upon urged movement of a portion of the passive electrical resonant circuit and is indicative of strain applied thereon a portion of the respective sensor assembly.Type: ApplicationFiled: September 21, 2012Publication date: March 27, 2014Applicant: CardioMEMS, Inc.Inventors: JASON KROH, Florent Cros, Christophe Courcimault

Patent number: 7812416Abstract: Disclosed are methods for attaching an integrated circuit to a substrate, and in particular, a fused silica substrate, along with apparatus fabricated using the methods. Exemplary apparatus comprises a glass substrate, a metallic layer disposed on the substrate, and an integrated circuit eutectically bonded to the glass substrate via the metallic layer. The integrated circuit and fused silica substrate form part of a hermetic sensor. In an exemplary sensor, a first trench is formed in a first substrate. A second trench that is deeper than the first trench is formed in the first substrate. A first plurality of electrodes are formed in the first trench. An integrated circuit is attached to the first substrate within the second trench using a solder preform.Type: GrantFiled: May 15, 2007Date of Patent: October 12, 2010Assignee: CardioMEMS, Inc.Inventor: Christophe Courcimault

Patent number: 7748277Abstract: An exemplary pressure cavity is disclosed that is durable, stable, and biocompatible and configured in such a way that it constitutes pico to nanoliter-scale volume. The exemplary pressure cavity is hermetically sealed from the exterior environment while maintaining the ability to communicate with other devices. Micromachined, hermetically-sealed sensors are configured to receive power and return information through direct electrical contact with external electronics. The pressure cavity and sensor components disposed therein are hermetically sealed from ambient pressure in order to reduce drift and instability within the sensor. The sensor is designed for harsh and biological environments, e.g., intracorporeal implantation and in vivo use. Additionally, novel manufacturing methods are employed to construct the sensors.Type: GrantFiled: October 18, 2006Date of Patent: July 6, 2010Assignee: CardioMEMS, Inc.Inventors: David O'Brien, Christophe Courcimault, Liang You, Yeun-Ho Joung, Mark Allen
