Abstract

A transcutaneous uterine contraction inhibiting device comprises a first plurality electrode positioned on an anterior side of an abdomen of a patient, a second plurality electrode positioned on the anterior side, and an electric current generator establishing electric current flow between the first plurality electrode and the second plurality electrode. The first plurality electrode is positioned above an upper portion of the uterus and extends laterally across the uterus. The second plurality electrode is positioned on a mid to lower portion of the uterus and also extends laterally across it. Further, a feedback unit can be provided for generating a signal indicative of any uterine contractions. The electric current generator then establishes an electric current in response to the signal from the feedback unit.

Claims

1. A method for affecting uterine contractions, comprising:

determining the presence of uterine contractions; and

establishing electrical current flow along an anterior side of an abdomen of a patient to affect the contractions.

2. A method as described in claim 1, further comprising:

placing electrodes on the abdomen of the patient; and

establishing the current flow between the electrodes.

3. A method as described in claim 2, further comprising placing plural electrodes of a same polarity on the abdomen.

4. A method as claimed in claim 1, further comprising:

placing an electrode of a first polarity on the abdomen;

placing plural electrodes of a second polarity on the abdomen; and

establishing the current flow between the first polarity electrode and the plural second polarity electrodes.

5. A method as described in claim 1, further comprising selecting the current flow to attenuate the uterine contractions.

6. A method as described in claim 1, wherein the step of establishing the electrical current flow comprises generating constant amplitude current pulses.

7. A method as described in claim 1, further comprising:

detecting uterine contraction with a sensor; and

controlling the electrical current flow in response to the uterine contractions.

8. A uterine contraction affecting device comprising:

electrodes for being placed on an anterior surface of an abdomen of a patient;

a generator for establishing electrical current between the electrodes to attenuate uterine contractions of the patient;

a sensor for detecting the uterine contractions; and

a controller for controlling the electrical current of the generator in response to the detected contractions.

9. A device as described in claim 8, wherein the generator generates constant current electrical pulses.

10. A device as described in claim 8, wherein the electrodes comprise:

a first polarity electrode; and

at least one second polarity electrode.
