Abstract
Abstract A puncturing device for insertion into the body, which has an ultrasonically coded displacement scale of gaseous inclusions regularly spaced along the length of the device. Owing to the acoustic reflectiveness of the gaseous inclusions, the precise location of the puncturing device can be directly and readily detected by an ultrasound visualization system. The acoustically reflective displacement scale enables the calibration of distances to be made directly from the ultrasound viewing screen. Located at the tip of the puncturing device is a gaseous inclusion which reveals the precise location of the tip of the device in the body.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
104 words
A probe for insertion into the body, said probe comprising: an elongated probe body, having a distal end and a proximal end penetrating means for penetrating said probe body into the body, said penetrating means including a penetrating tip located at the distal end of said probe body; and acoustic reflector means, located at the penetrating tip, for creating a spot of high acoustic reflectiveness at said penetrating tip, said acoustic reflector means including gaseous inclusion means for trapping a gas pocket within said probe, whereby the location of the tip of said probe body can be readily detected by an ultrasound visualization system.
Claim 2
Dependent Claim
104 words
A probe for insertion into the body, said probe comprising: an elongated probe body, having a distal end and a proximal end penetrating means for penetrating said probe body into the body, said penetrating means including a penetrating tip located at the distal end of said probe body; and acoustic reflector means, located at the penetrating tip, for creating a spot of high acoustic reflectiveness at said penetrating tip, said acoustic reflector means including gaseous inclusion means for trapping a gas pocket within said probe, whereby the location of the tip of said probe body can be readily detected by an ultrasound visualization system.
Claim 3
Dependent Claim
90 words
A surgical puncturing device comprising: (a) a hollow puncturing cannula; (b) a stylette, slidably received by said puncturing cannula, said stylette being suitable for insertion into the body in combination with said puncturing cannula; and (c) ultrasonically reflective displacement scale means for incorporating in said puncturing device an ultrasonically reflective displacement scale that is detectible by an ultrasound visualization system, said means including a plurality of gas trapping means for trapping gas pockets within said puncturing device, said plurality of gas trapping means being regularly spaced along said puncturing cannula.
