Patent number: 11800806Abstract: A method for fabricating a multi-cell electroacoustic transducer comprises placing a rail layer onto a base, the rail layer comprising a plurality of apertures arranged in an array, filling cavities in the rail layer with a polymer, and applying a flexural plate to the rail layer. The transducer achieves high transmission sensitivity across a broad bandwidth. The transducer may be designed to have a broad or a focused directivity pattern, or may be multi-frequency, depending on the particular application and has a range of applications.Type: GrantFiled: October 22, 2020Date of Patent: October 24, 2023Assignee: Microtech Medical Technologies Ltd.Inventors: Alessandro Stuart Savoia, Giosuè Caliano, Alexander Melamud, Eric S.

Patent number: 11490823Abstract: The devices and methods generally relate to vibratable sensors for measuring ambient fluid pressure, in particular implantable sensors. The devices and methods are suited to implantation within the body to monitor physiological conditions, such as portal and/or hepatic venous blood pressure, and allow frequent, remote interrogation of venous pressure. The sensor devices are relatively small compared to conventional devices for measuring fluid pressure and can be implanted in the portohepatic venous system, whereas conventional devices are too large. The small size of the device is accomplished by using a thick sensor membrane, compared to conventional devices, and by limiting the size of additional elements of the device relative to the size of the sensor membrane. The thicker sensor member also obviates the need for multiple sensor arrays and maintains the accuracy and robustness of the sensor device. A data capture, processing, and display system provides a pressure measurement reading.Type: GrantFiled: September 13, 2018Date of Patent: November 8, 2022Assignee: Microtech Medical Technologies Ltd.Inventors: Yoram Richter, Eric S.

Patent number: 11160506Abstract: This invention relates to an implantable device for a physiologic sensor, comprising an implantable expandable anchor, a bridge on which the sensor is secured, as well as an optional adapting ring. The invention also relates to a method of monitoring bodily functions using the anchor and sensor. The anchor is compressed and the bridge assumes an elongated shape during delivery to a target lumen. Upon deployment at the target site, the anchor expands and the bridge bows into the interior lumen of the expanded anchor, distancing the sensor from the vessel wall. This invention also relates to a method of manufacturing said device and a method of implanting a sensor.Type: GrantFiled: February 20, 2019Date of Patent: November 2, 2021Assignee: Microtech Medical Technologies LtdInventors: Yekaterina Dlugach, Nadav Agian

Patent number: 10847708Abstract: The present invention relates to a transducer device having a planar array of electroacoustic cells, each including a piezoelectric bilayer unit. The transducer device achieves high transmission sensitivity across a broad bandwidth. The transducer device may be designed to have a broad or a focused directivity pattern, or may be multi-frequency, depending on the particular application and has a range of applications. For example, the transducer device may be used with an implanted passive ultrasonically excitable resonating sensor, to excite the sensor and/or to interrogate the sensor, for example in conjunction with Doppler-based analysis of the resonance frequency of the sensor, and/or to locate an implanted sensor. The invention also relates to a method of manufacturing the device.Type: GrantFiled: July 10, 2015Date of Patent: November 24, 2020Assignee: Microtech Medical Technologies Ltd.Inventors: Alessandro Stuart Savoia, Giosuè Caliano, Alexander Melamud, Eric S.

Patent number: 10105067Abstract: The devices and methods generally relate to vibratable sensors for measuring ambient fluid pressure, in particular implantable sensors. The devices and methods are particularly well-suited to implantation within the body of a living animal or human to monitor physiological conditions, such as portal and/or hepatic venous blood pressure, and allow frequent, remote interrogation of venous pressure using the resonance frequency of an implanted sensor. The sensor devices are relatively small compared to conventional devices for measuring fluid pressure and can be implanted in the porto-hepatic venous system, whereas conventional devices are too large.

Patent number: 8356399Abstract: A method of protecting a resonating sensor is described. The protected resonating sensor may include at least one passive ultrasonically excitable resonating sensor unit. Each sensor unit has one or more vibratable members having a resonating frequency that varies as a function of a physical variable in a measurement environment. The sensor is protected by forming one or more protective chambers defined between a compliant member and the vibratable member(s). A substantially non-compressible medium is disposed within the protective chamber(s). The compliant member has a first side that may be exposed to a measurement environment and a second side that may be exposed to the substantially non-compressible medium. The substantially non-compressible medium may be a liquid or gel and is in contact with the vibratable member(s). When the medium is a liquid, the chamber is sealed. When the medium is a gel, the chamber may be sealed or non-sealed.Type: GrantFiled: November 19, 2007Date of Patent: January 22, 2013Assignee: Microtech Medical Technologies Ltd.Inventor: Shay Kaplan
