Embodiment Construction

[0021] Various embodiments will be described in detail with reference to the accompanying drawings. Where appropriate, the same reference numbers will be used throughout the drawings to refer to the same or like parts. References made to particular examples and implementations are for illustrative purposes and are not intended to limit the scope of the invention or the claims.

[0022] The words "exemplary" and / or "such as" are used herein to mean "serving as an example, instance, or illustration." Any implementation described herein as "exemplary" or "such as" is not necessarily to be construed as preferred or preferred over other implementations.

[0023] The systems, methods, and devices of various embodiments enable monitoring the dose of an infusate to a patient by monitoring the displacement of a bellows that provides a reservoir for the infusate. An embodiment drug delivery system may include a bellows sensor configured to measure a displacement or a change in shape o...

Abstract

An implantable drug delivery device and method that includes a bellows sensor for detecting the displacement of a bellows within an infusate reservoir. Sensor data from the bellows sensor may enable indirect measurement of the flow conditions of the implantable drug delivery device or connected catheter. A processor within the implantable drug delivery device may use the sensor data to determine whether delivery of infusate to a patient over time is outside normal or acceptable parameters and take an action in response.

Description

[0001] related application [0002] This application is a continuation-in-part of U.S. Patent Application Serial No. 15 / 098,663, filed April 14, 2016, entitled "Implantable Drug Delivery Device with Flow Measuring Capabilities" , said U.S. patent application claims priority benefit to U.S. Provisional Application No. 62 / 148,457, entitled "Implantable Drug Delivery Device with Flow Measurement Capability," filed April 16, 2015, the entire contents of all applications Incorporated herein by reference. technical field [0003] The present invention generally relates to implantable infusion devices for delivering drugs or other fluids to a patient. Background technique [0004] Various implantable devices exist for delivering infusions, such as drugs, to patients. One such device is an implantable valve accumulator pump system. The system includes an electronically controlled metering assembly positioned between the drug reservoir and the outlet conduit. The metering assemb...
