Embodiment Construction

[0015] figure 2 A sensor assembly 10 is shown having a plurality of sensor elements 12 each coupled to a compressible retention device 16 implanted in a blood vessel 26 of a human body, according to one embodiment of the invention. As described below, sensor assembly 10 includes two or more sensor elements 12 and can be implanted within the cardiovascular system of a human body to measure blood pressure at the implanted site. The sensor assembly 10 is shown positioned within a blood vessel 26 within a human body. The compressible retention device 16 is expandable into contact with the inner surface 46 of the blood vessel 26 to retain the sensor assembly 10 in its proper position. The compressible retaining device 16 may be a brace, strut or other similar device. Each of the sensor elements 12 is bonded to the compressible holding means 16 by welding the sensor elements 12 to the holding means 16 or by using other known bonding structures. The sensor assembly 10 is shown wit...

Abstract

A system includes multiple slave devices implanted in a human body, wherein each slave device includes a communication module operable to receive transmitted communications and is associated with a permanent device identifier. The system further includes a master device including a communications module operable to address a first communication to a selected slave device using the permanent device identifier associated with the selected slave device, wherein the first communication includes a local identifier assigned to the selected slave device, the assigned local identifier does not match any other local identifier assigned to any other slave device implanted in the human body, and subsequent communications are addressed to the selected slave device using the assigned local identifier.

Description

technical field [0001] The present invention relates to sensors implantable in the human body. More specifically, the present invention relates to devices and methods for implanting multiple sensors in the human body. Background technique [0002] Medical sensors can be implanted in the human body to obtain diagnostic data about specific bodily functions. For example, pressure sensors located within the body's vascular system are capable of measuring blood pressure at many different locations within the body. FIG. 1 shows a typical sensor assembly 2 with a sensor 4 and a compressible retaining element 6 inside a blood vessel 8 . The sensor 4 is a self-contained device with its own power supply and communication circuitry for transmitting data to a remote device. Such sensors can be implanted in the body by inserting a catheter into the body and moving the catheter through the cardiovascular system until the end of the catheter is at the desired implantation location. The...
