Abstract
Devices and methods for treating postpartum hemorrhaging, including devices and methods for trans-cervical introduction into a uterine cavity of a patient comprising an elongated shaft with an expandable working end; a negative pressure source coupled to an extraction lumen in the elongated shaft; an electrode arrangement carried by the expandable working end; and an electrical source and controller coupled to the electrode arrangement adapted to deliver electrical stimulation to walls of the uterine cavity.
Claims21
A method for treating uterine atony to mitigate postpartum hemorrhaging in a patient, comprising:
- positioning an electrode arrangement within a uterine cavity, wherein the electrode arrangement comprises a plurality of electrodes disposed on an outward-facing surface of a working end that is configured to be expandable;
- creating a seal near an entrance to the uterine cavity;
- applying negative pressure through the working end to contract the uterine cavity and draw a uterine wall into contact with the electrode arrangement;
- and
- delivering electrical stimulation current to the uterine wall from the electrode arrangement to cause contraction of uterine muscles and to reduce postpartum bleeding.
A system for treating postpartum hemorrhaging in a patient, comprising:
- a device configured for trans-cervical introduction into a uterine cavity of a patient comprising an elongated shaft with an expandable working end;
- a negative pressure source coupled to an extraction lumen in the elongated shaft;
- an electrode arrangement carried by the expandable working end;
- and
- an electrical source and controller coupled to the electrode arrangement adapted to deliver electrical stimulation to walls of the uterine cavity.
