First Claim
Patent Images
1. A surgical drain for sensing a physiological property of at least one tissue and draining fluid from a body comprising:
- a) an elongated conduit configured to be implanted in a patient'"'"'s body and rest against a first tissue and a second tissue within the body to drain fluid from the patient'"'"'s body, wherein the elongated conduit comprises a drain portion having openings spaced along substantially the length of the drain portion, wherein the surgical drain is not configured to penetrate either the first or second tissues;
b) a first sensing element configured to sense a physiological property of the first tissue adjacent to a first location of the elongated conduit; and
c) a second sensing element configured to sense the same physiological property of the second tissue adjacent to a second location of the elongated conduit different than the first location.

Abstract
The present invention is directed to devices and methods of using a surgical drain, and more particularly to a surgical drain having at least one sensor for monitoring and/or recording the condition of the anatomical site or fluid emitted from the site where the surgical drain is placed. The invention may also include modifications of the surgical drain to improve stabilization or immobilization in the proximity of the anatomical site to be monitored.

20. A surgical drain for sensing a physiological property of at least one tissue and draining fluid from a body comprising:
-
a) an elongated conduit configured to be implanted in a patient'"'"'s body in proximity to an organ at a first location and to a tissue that is not part of the organ at a second location that is different from the first location, the elongated conduit having a drain portion with openings spaced along substantially its length and configured to drain fluid from the patient'"'"'s body in the vicinity of the organ and the tissue, wherein the surgical drain is not configured to penetrate either the first or second tissues; b) a first sensing element coupled to the elongated conduit and configured to sense a physiological property of the organ; and c) a second sensing element coupled to the elongated conduit and configured to separately sense the same physiological property of the tissue. - View Dependent Claims (21)
