Abstract
An organ restraint device includes a first end portion including a fluid inlet channel, a second end portion including a fluid outlet channel, a medial body portion coupled between the first end portion and the second end portion. The medial body portion includes one or more fluid channels that couple the fluid inlet channel to the fluid outlet channel and a plurality of tension adjustment apertures
Claims36
An organ restraint device comprising:
- a first end portion including a fluid inlet channel;
- a second end portion including a fluid outlet channel;
- and
- a medial body portion coupled between the first end portion and the second end portion, the medial body portion comprising:
- one or more fluid channels that couple the fluid inlet channel to the fluid outlet channel;
- and
- a plurality of tension adjustment apertures.
A method of treating atria of a heart to prevent atrial fibrillation, the method comprising:
- inserting a first end of an organ restraint device into a chest cavity of a patient;
- passing the first end of the organ restraint device around a posterior side of a heart of the patient;
- wrapping the organ restrain device over one or more of a right atrium and a left atrium of the heart;
- threading a tension adjustment line through one or more first apertures associated with a first longitudinal half of the organ restrain device;
- threading the tension adjustment line through one or more second apertures associated with a second longitudinal half of the organ restraint device;
- drawing the one or more first apertures towards the one or more second apertures by pulling on the tension adjustment line;
- inserting cooling fluid into one of the first end and a second end of the organ restraint device;
- and
- expelling the cooling fluid from another of the first end and the second end.
A method of removing an organ restraint device from a chest cavity of a patient, the method comprising:
- unlocking a tension adjustment line threaded through one or more apertures of an organ restraint device wrapped around one or more of a right atrium and a left atrium of a heart of a patient;
- withdrawing the tension adjustment line from a chest cavity of the patient;
- evacuating fluid from the restrain device;
- and
- withdrawing the organ restraint device from the chest cavity of the patient by pulling on a first end of the organ restraint device to thereby draw a second end of the organ restraint device around a posterior side of the heart.
An atria restraint band comprising:
- a first distal end portion;
- a second distal end portion;
- a first atrium contact portion positioned along a longitudinal dimension of the atria restraint band, the first atrium contact portion comprising a first protrusion in a first transverse direction, and a second protrusion in a second transverse direction opposite the first transverse direction, the second protrusion being aligned longitudinally with the first protrusion;
- a second atrium contact portion positioned along the longitudinal dimension of the atria restraint band, the second atrium contact portion comprising a third protrusion in the first transverse direction, and a fourth protrusion in the second transverse direction, the third protrusion being aligned longitudinally with the fourth protrusion;
- and
- a transversely-recessed groove positioned between the first and second atrium contact portions along the longitudinal dimension of the atria restraint band.
