Abstract

Certain embodiments described herein pertain to optical sensors, systems and methods for continuous glucose monitoring. In some embodiments, methods of preparing a layered optical sensor are disclosed. The optical sensor can be formed by laminating a plurality of sheets together to form a final sensor. In some embodiments, the sensor tip comprises a oxygen conduit, an enzymatic layer, and an sensing layer. In some embodiments, the sensor includes a plurality of waveguides configured to direct light to and from a target material, such as an oxygen sensing polymer. Systems are also disclosed for an adhesive system for attaching an optical sensor-transmitter system. Methods and systems are also disclosed for a sensor inserter system. The inserter can include a lancet tip that includes a convex feature attached to a first surface of the lancet tip.

Dependent claims

A system comprising:

an inserter, the inserter including an insertion member for piercing skin tissue, wherein the insertion member comprises a retaining structure and a tip disposed distally of the retaining structure;
and
an implantable device element, the device element including a distal end in a form of a loop, wherein the loop is configured to pass over the retaining structure to be retained by a distal facing surface of the retaining structure;
wherein the retaining structure is configured to retain the device element prior to and during insertion of the insertion member into the skin tissue and release the device element insertion member upon removal of the insertion member from the skin tissue thereby implanting the device element within the skin tissue.
