Systems and methods for determining pressure and spacing relating to anatomical structures
First Claim
1. A device for determining a pressure exerted within an anatomical structure, said device comprising:
- a) a sensor comprising an encapsulated member having (i) a membrane enclosing an encapsulated volume therewithin and (ii) a body of supportive material disposed within the membrane that substantially fills and defines the encapsulated volume, the sensor having a link extending therefrom, said sensor being positionable within the anatomical structure, said sensor being operative to compress against said anatomical structure, measure pressure exerted within said anatomical structure, produce a signal representative of the pressure exerted within said anatomical structure and transmit said signal through said link; and
b) a monitor coupled to said link for receiving said signal generated by said sensor, said monitor being operative to provide a quantifiable indication of the compressive force exerted within said anatomical structure,wherein the supportive material is compressive foam disposed within the encapsulated member, said compressive foam being operatively transitional between a first expansive state when a first baseline amount of pressure is applied thereto and a second compressed state whereby said foam compresses to assume a configuration having a reduced volume corresponding to a second higher amount of pressure applied upon the external surface of said encapsulated member.

Abstract
Systems and methods for measuring the pressure exerted between or within anatomical masses/structures, as well as the position and/or spatial dimensions of an anatomical structure. According to a preferred embodiment, the invention comprises a sensor element positionable between anatomical structures or within an anatomical structure. The sensor is operative to generate a signal indicative of the pressure being exerted therebetween or therewithin. The sensor may be operative to measure spatial dimensions between structures or within a structure. A monitor coupled to the sensor receives a signal generated thereby and provides an indication as to the spacing or pressure being measured. The systems and methods may be utilized in diagnostic tests or surgical procedures.
