LOW NOISE OXIMETRY CABLE INCLUDING CONDUCTIVE CORDS
First Claim
1. A medical cable configured to communicate signals indicative of light attenuated by body tissue from a noninvasive optical sensor positioned with respect to said tissue to a patient monitor, said patient monitoring configured to process said signals and determine one or more physiological parameters of a patient, the cable comprising:
- an inner bundle including (i) conductors configured to carry said signals, each conductor surrounded by an insulator and (ii) at least one flexible conductive polymer cord;
an inner shield at least partially surrounding the inner bundle;
an inner jacket surrounding said inner shield; and
an outer jacket.

Abstract
In an embodiment, one or more conductive cable cords are twisted with the sensitive signal carrying cables. The cords may advantageously comprise dummy wires, or very flexible hollow cables without an inner conductor. As the conductive cords do not carry and inner conductor, the conductive cords are individually flexible and small, resulting in a twisted bundle that more is flexible while potentially having a smaller outer diameter.

15. A medical cable comprising:
-
one or more conductive cords weaved together with wires, the wires communicating low level signals usable to determine measurements of physiological parameters of a patient monitored by one or more medical devices communicating through said wires to one or more medical monitors; a first jacket and shield enclosing said conductive cords to form an inner bundle; and a second jacket enclosing said inner bundle. - View Dependent Claims (16, 17, 18, 19, 20)
