 This paper reports on a micromachined stent that has been developed to serve as an antenna for wireless monitoring of implantable microsensors. A 4 mm long, 3.5 mm diameter design is fabricated from 50 µm thick stainless steel foil using a batch-compatible micro electro-discharge machining process. As it is expanded during deployment, the stent transforms(More)
BACKGROUND This study analyzed the overall nocturnal performance during home use of a long-term subcutaneous implantable continuous glucose monitoring (CGM) sensor. SUBJECTS AND METHODS In this study, 12 subjects with type 1 diabetes mellitus (T1DM) (mean±SD age, 37±8 years; mean±SD disease duration, 11±6 years) were implanted with an investigational(More)
A continuous glucose monitoring (CGM) system consisting of a wireless, subcutaneously implantable glucose sensor and a body-worn transmitter is described and clinical performance over a 28 day implant period in 12 type 1 diabetic patients is reported. The implantable sensor is constructed of a fluorescent, boronic-acid based glucose indicating polymer(More)
OBJECTIVE It is known that continuous glucose monitoring (CGM) systems can lower mean glucose compared with episodic self-monitoring of blood glucose. Implantable CGM systems may provide additional benefits. RESEARCH DESIGN AND METHODS We studied the Eversense (Senseonics Inc.) implantable CGM sensor in 71 participants aged 18 years and older with type 1(More)
This article describes the algorithm for a continuous glucose monitor (CGM). The CGM system consists of an external reader and an insertable fluorescence based sensor. The sensor consists of a miniaturized optical sensor that incorporates a biocompatible macromolecular indicator that selectively binds glucose. It is designed to be subcutaneously inserted(More)
This paper reports a micromachined antenna stent (stentenna) that is integrated with implantable microsensors for wireless sensing of blood flow and pressure with no battery. A device that has 20-mm length and 3.5-mm diameter (after expansion) is fabricated from 50 µm thick stainless steel foil by using batch-compatible micro-electro-discharge machining.(More)
This paper presents an integrated circuit (IC) that merges integrated optical and temperature transducers, optical interface circuitry, and a near-field communication (NFC)-enabled digital, wireless readout for a fully passive implantable sensor platform to measure glucose in people with diabetes. A flip-chip mounted LED and monolithically integrated(More)
BACKGROUND Continuous glucose monitoring (CGM), which enables real-time glucose display and trend information as well as real-time alarms, can improve glycemic control and quality of life in patients with diabetes mellitus. Previous reports have described strategies to extend the useable lifetime of a single sensor from 1-2 weeks to 28 days. The present(More)
