Gastric restriction device data handling devices and methods
First Claim
1. A method of forming a restriction in a patient, comprising:
- using an implantable pressure sensing device to obtain pressure data over a period of time related to a pressure within an implantable restriction device configured to form a restriction in a patient;
determining a portion of the obtained pressure data which corresponds to a time within the period of time when a meal was consumed by the patient based on at least one of a time of day the pressure data was obtained and a duration of the obtained pressure data being above a nominal pressure level;
storing at least a portion of the obtained pressure data at the implantable pressure sensing device;
in response to a signal from an external device, downloading at least a portion of the stored data to the external device;
telemetrically providing power to the implantable pressure sensing device from the external device by moving the external device in proximity of the implantable pressure sensing device, wherein telemetrically providing power triggers a download of the portion of the stored data to the external device; and
discarding pressure data obtained during the period of time that does not correspond to the time within the period of time when the meal was consumed such that the discarded data is not downloaded to the external device.

Abstract
Methods and devices are provided for handling data in an implantable restriction system. In general, the methods and devices allow collection, analysis, storage, and transmission of pressure measurements. Pressure measurement data can be compressed before storing it. Additionally, not all pressure data need be recorded or retained, such as data substantially equaling a resting or nominal pressure of an implantable restriction device indicative of little to no pressure variation and data indicative of isolated, non-recurring events. Any pressure measurement data that is recorded can be transmitted to an external device using power telemetrically provided by the external device.

8. A method of forming a restriction in a patient, comprising:
- obtaining pressure data related to a pressure within an implantable restriction device configured to form a restriction in a patient;
determining a portion of the obtained pressure data to retain prior to communicating pressure data to an external reading device, the determining comprising comparing the obtained pressure data with a pre-programmed pressure chosen by a user and indicating a nominal pressure within the implantable restriction device; storing in an implantable memory the obtained pressure data that exceeds the pre-programmed pressure; communicating the portion of the obtained pressure data stored in the memory to the external reading device; determining to retain pressure data obtained during the pre-determined time of day and determining to not retain pressure data obtained outside the pre-determined time of day; storing in the implantable memory any of the pressure data obtained during the pre-determined time of day; and communicating the stored pressure data obtained during the pre-determined time of day. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16)

17. A method of forming a restriction in a patient, comprising:
- using an implantable pressure sensing device to obtain pressure data over a period of time related to a pressure within an implantable restriction device configured to form a restriction in a patient;
storing at the implantable pressure sensing device an absolute value of the obtained pressure data at a start of the period of time; storing at the implantable pressure sensing device difference values of the obtained pressure data relative to the absolute value for a remainder of the period of time after the start; determining a portion of the obtained pressure data which corresponds to a time within the period of time when a meal was consumed by the patient based on at least one of a time of day the pressure data was obtained and a duration of the obtained pressure data being above a nominal pressure level; and discarding pressure data obtained during the period of time that does not correspond to the time within the period of time when the meal was consumed such that the discarded data is not downloaded to an external device. - View Dependent Claims (18, 19, 20)
