Abstract: Embodiments of the invention provide optimized sputtered metallic surfaces adapted for use with implantable medical devices as well as methods for making and using such polymeric surfaces. These sputtered metallic surfaces have features that function to inhibit or avoid an inflammatory immune response generated by implantable medical devices. Typical embodiments of the invention include an implantable glucose sensor used in the management of diabetes having a sputtered metallic surface adapted to contact an in vivo environment.

Abstract: Medical devices, systems and methods are provided. One method involves obtaining fabrication process measurement data for a plurality of instances of a sensing element, obtaining reference output measurement data from the plurality of instances in response to a reference stimulus, determining a predictive model for a measurement output of the sensing element as a function of fabrication process measurement variables based on the relationship between the fabrication process measurement data and the reference output measurement data, generating a simulated output measurement distribution across a range of the fabrication process measurement variables using the predictive model, identifying performance thresholds for the measurement output based on the simulated output measurement distribution, obtaining output measurement data from the instance of the sensing element in response to the reference stimulus, and verifying the output measurement data satisfies the performance threshold prior to calibrating a subsequent instance of the sensing element.

Abstract: Embodiments of the invention provide optimized polymeric surfaces adapted for use with implantable medical devices as well as methods for making and using such polymeric surfaces. These polymer surfaces have a constellation of features that function to inhibit or avoid an inflammatory immune response generated by implantable medical devices. Typical embodiments of the invention include an implantable glucose sensor used in the management of diabetes having a polymer surface with the disclosed constellation of features.

Abstract: A medical sensor device includes a sensor assembly including an underside surface for attachment against a patient's skin, a sensor portion to detect a characteristic of the patient, and sensor assembly contacts which in operation carry signals representing the detected characteristic. The device also includes a transmitter assembly removably engageable with the sensor assembly and including circuitry to take the signals from the sensor assembly contacts and to transmit readings of the detected characteristic to external equipment. The device also includes mechanical interface components on the sensor assembly and the transmitter assembly which allow the transmitter assembly to be brought into abutment with the sensor assembly at a first angular position via relative axial movement between them, and then allow a relative rotation of the assemblies with respect to one another towards a second angular position and presents axial separation of the assemblies in the second angular position.
