Miniature pressure sensor assembly for catheter
First Claim
1. A system comprising:
- A multi-layer co-fired ceramic (MLCC) package comprising a cavity, at least one internal bond pad, at least one external connection point, and at least one internal interconnect wherein the at least one internal bond pad is positioned within the cavity, wherein the at least one external connection point is on an exterior of the MLCC package, and wherein the at least one internal interconnect provides an electrical connection between at least one of the at least one internal bond pad and at least one of the at least one external connection point;
the MLCC package including two or more ceramic layers that are co-fired together, wherein the cavity is defined by at least some of the ceramic layers;
a sensor positioned and attached within the cavity, and electrically connected to the at least one internal bond pad to form an MLCC sensor assembly; and
a catheter comprising at least one lumen wherein at least one of the at least one lumen is a sensor lumen and wherein the MLCC sensor assembly is positioned within the sensor lumen.

Abstract
A pressure sensor assembly configured for use with a catheter. In one illustrative embodiment, the pressure sensor assembly may include a multi-layer co-fired ceramic (MLCC) package. The MLCC package may include two or more ceramic layers that are co-fired together, with a cavity defined by at least some of the ceramic layers. At least one internal bond pad is provided within the cavity, and at least one external connection point is provided on the MLCC package exterior. A sensor, such as a pressure sensor, may be positioned and attached within the cavity. The sensor may be electrically connected to at least one of the internal bond pads. In some cases, a sealant may be used to encapsulate the sensor within the cavity. Once fabricated, the MLCC sensor assembly may be provided in a sensor lumen of a catheter.
