Abstract: A kit for implanting a flexible multi-lead cardiac monitor for recording biosignals when the monitor is placed under the skin. The kit includes the monitor, an implantation tool for implanting the monitor under the skin, and optionally a surgical knife. The monitor exhibits an open-circular shape, is based on a flexible printed circuit board with at least two sensing electrodes, optionally a ground electrode, includes a main circuit based on the FPCB, and is free of a casing. The implantation tool exhibits an open-circular shape to reversibly receive the monitor, includes a base to reversibly accommodate the monitor, a handle connected to the base, and a slider reversibly insertable into the base. A process to make the monitor of the kit, the monitor obtainable according to the process, a process to monitor biosignals with the monitor, and the use of the kit, of the monitor and of the implantation tool.

Abstract: A wearable cuff based on a carrier material with an integrated signal recorder for measurements of biosignals on the skin of a living body recording at an upper arm of a human body. At least one electrode is connected to the carrier material via a reversibly compressible material. The electrodes, the base of the main circuit, and the conductors of the signal recorder are based on one and the same flexible printed circuit board (FPCB). The carrier material is an elastic material. The conductors exhibit a zig-zag, U-shape, ?-shape and/or a meandering form. The carrier material includes a woven and/or a nonwoven layer being coated with a thermoplastic polymer layer. A process to make the cuff, a process to measure biosignals on the skin of a living body, for long-term ECG recording at an upper arm of a human body, and the use of the cuff to record biosignals on the skin of a living body.
