Publication number: 20100198305Abstract: Techniques are disclosed for detecting a functionality of a medical device implanted within the human body. A testing method includes delivering power to and measuring an electrical response of ion exchange polymer metal composite (IPMC) material that is part of the implant device in a first testing interval. Power can be transmitted at radio frequencies which penetrate tissue such that direct contact with the implant device is not required. Following the first testing interval, the implant can be powered continuously for a predetermined time. The implant can be powered in a second testing interval and the electrical response can again be measured. A functionality of the implant device can be detected based on the electrical response in the first and second testing intervals. The testing method can be practiced in connection with a handheld device, a retainer, or other suitable apparatus.Type: ApplicationFiled: January 29, 2010Publication date: August 5, 2010Applicant: Pavad Medical, Inc.Inventor: John Michael Farbarik

Publication number: 20100049227Abstract: Methods and tools are disclosed for inserting an implant device that treats snoring and apnea of a patient by altering the position of a soft palate. Methods and tools can make an incision in patient's soft and hard palate to create a cavity that can house the implant. The tools can have visually observable markings that can be aligned with the incision, thus controlling the depth of the cavity. A needle having an incision edge can be used to make an incision in patient's soft palate. The needle can be bent into a suitable longitudinal shape to allow easier access and visualization of the process. A blade that makes the cavity in the tissue can be housed inside a channel in the needle. The tools may have stoppers to prevent excessive extension and retraction of the blade thus preventing an excessive cavity depth. Some tools may also house the implant device, which may be implanted after the cavity is formed.Type: ApplicationFiled: July 7, 2008Publication date: February 25, 2010Applicant: Pavad MedicalInventors: Anant V.
