1. A linear electrode array equipped catheter device comprising:
- an elongate catheter body having a lumen and a distal end that penetrates through tissue;
a linear electrode array on or in the catheter body, said electrode array comprising a plurality of electrodes arranged in a row at spaced apart locations, each of said electrodes being operative to sense a property of tissue or body fluid and to generate signals in response to the sensed property; and
a display apparatus for displaying indicia of the sensed property.

Abstract
Catheter devices, systems and methods wherein linear electrode arrays are disposed on catheters that penetrate through tissue such that the electrodes of the array may be used to sense properties of surrounding tissue or body fluid. The invention is useable for various purposes, including the delivery of a substance, article or device to a specific target location within the body of a human or animal subject.

- 11. A system comprising a linear electrode array equipped catheter device in combination with a tissue penetrating catheter device that is positionable within a body lumen and has a tissue penetrating member that is advanceable to a first location outside of that body lumen, said linear electrode array equipped catheter device being thereafter advanceable through or over the tissue penetrating member such that the linear electrode array equipped catheter device will advance into tissue or body fluid and the electrodes of the linear electrode array will sense a property of that tissue or body fluid.

15. A method for delivering a substance, article or device to a target location within the body of a human or animal subject, said method comprising the steps of:
-
(A) providing a linear electrode array equipped catheter device that comprises i) an elongate catheter body having a distal end and a lumen, ii) a linear electrode array on or in the catheter body, said electrode array comprising a plurality of electrodes arranged in a row at spaced apart locations, each of said electrodes being operative to sense a property of tissue or body fluid and to generate signals in response to the sensed property and iii) a display apparatus for displaying indicia of the sensed property; (B) inserting the linear electrode array equipped catheter device into the subject'"'"'s body and advancing the linear electrode array equipped catheter device through tissue or body fluid such that the electrodes of the linear electrode array will sense a property to the tissue or body fluid and the display apparatus will display indicia of the property sensed by each electrode; (C) determining on the basis of the indicia displayed by the display device when the catheter body is positioned such that introduction of the substance, article or device through the lumen of the catheter body will result in delivery of the substance, article or device to the target location; and (D) delivering the substance, article or device through the lumen of the catheter body to the target location. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41)
