The objective of this paper is to assist developers of medical sensors to better formulate the clinically relevant design criteria and required performance characteristics of their novel sensor based on an understanding of how these devices will be used by physicians. Sensor technologies play a central role in medicine, and the most critical aspect of the sensor's clinical utility relates to these design decisions. Clinically, sensors are used by health care providers to make both diagnostic and management decisions, and the sensors that aid in these decisions are evaluated by certain clinical, as well as analytical, criteria. Failure to adequately address these end-user requirements can lead to the development of sensors without clinical utility.

Ligand binding to membrane proteins initiates numerous therapeutic processes. Surface plasmon resonance (SPR), a popular method for analyzing molecular interactions, has emerged as a promising tool for in situ determination of membrane protein binding kinetics owing to its label-free detection, high surface sensitivity, and resistance to intracellular interference. However, the excitation of SPR relies on noble metal films, typically gold, which are biologically incompatible and can cause fluorescence quenching.

Background: The IntellaNav MiFi OI catheter (MiFi) is equipped with a sensor for local impedance (LI) monitoring and three mini-electrodes. In this study, we investigated the target LI values for a successful pulmonary vein isolation (PVI) under the pacing and ablation technique using the MiFi catheter.
Methods: Twenty-seven patients underwent PVI using the MiFi catheter under mini electrode pacing from the MiFi catheter.
