IMPLANTABLE DEVICE WITH JUMPER Russian patent published in 2017 - IPC A61B5/00 A61F2/915 

FIELD: medicine.

SUBSTANCE: implantable device for physiological sensor securing comprises a fastener containing a plurality of tortuous rings defining a clearance along a longitudinal axis and having a compressed configuration and an expanded configuration and a jumper attached to the fastener and having the first end and the second end. In the compressed configuration of the fastener, the jumper is substantially aligned on its longitudinal axis, and in the expanded configuration of the fastener, the jumper protrudes into the lumen. The method for creation of an implantable device for physiological sensor securing consists of making the jumper and the fastener in the form of a single unit, fastener and jumper mounting on the core having the diameter of the desired expanded fastener and a recess, jumper placement over the recess and heat treatment of the fastener and jumper to obtain a thermomechanical shape and mount the sensor on the jumper. A method for creation of an implantable device for physiological sensor securing, according to which the fastener is made first, then the jumper is made, then the fastener and the jumper are heat-treated, then the jumper is attached to the fastener and the sensor is assembled with the jumper. A method for sensor implantation including, at first, preparation of an implantable device for physiological sensor securing, then delivery of the said device to the lumen, and thereafter, expansion of the fastener, thereby causing the jumper to protrude into the said lumen and initiation of the sensor protrusion into the said lumen. The sensor implantation system comprises a delivery catheter and an implantable device for physiological sensor securing located on the delivery catheter.

EFFECT: device provides maximum sensor accuracy due to creation of an implantable device with a possibility of its compression.
