Abstract
A minimally invasive device for performing direct cardiac massage including an inflatable bladder mounted on a rigid inflation tube. The rigid inflation tube is used to push the bladder into the sternocostal space through an incision in the upper abdomen just below the xiphoid process. A tear-away insertion sleeve is provided over the balloon, so that the device may easily be inserted in to the body. The insertion sleeve includes various features that assist in placement of the device and removal of the sleeve. After insertion into the sternocostal space and removal of the insertion sleeve, the bladder is repeatedly inflated and deflated to massage the heart and provide blood flow.
Claims19
A method of treating a patient, said method comprising the steps of:
- performing surgery within the chest of the patient;
- providing a cardiac massage device adapted for cardiac massage from within the chest of the patient;
- inserting the cardiac massage device into the patient between the sternum and the heart, and positioning the cardiac massage device so that when operated the cardiac massage device will compress the heart;
- leaving the cardiac massage device in the patient after completing the surgery;
- conditionally, operating the cardiac massage device to massage the heart of the patient if the patient suffers cardiac arrest after the surgery;
- and
- removing the cardiac massage device after a perioperative period.
A method of treating a patient, said method comprising the steps of:
- performing surgery within the chest of the patient;
- providing a cardiac massage device adapted for cardiac massage from within the chest of the patient, said device comprising:
- a balloon adapted to assume an inflated state and a deflated state, wherein the balloon has a configuration sized and dimensioned to compress the heart when said balloon is inflated within the chest of the patient;
- a supply of fluid operably connected to the balloon and to a means for delivering fluid, said means for delivering operable to deliver fluid from the supply to the balloon;
- inserting the balloon into the patient between the sternum and the heart, and positioning the balloon so that when inflated the balloon will compress the heart;
- leaving the balloon in the patient after completing the surgery;
- and
- conditionally, operating the means for delivering fluid to repeatedly inflate and deflate the balloon if the patient suffers cardiac arrest after the surgery.
