Sectional cardiac support device and method of delivery
A cardiac support device formed from a plurality of compliant sections individually delivered and deployed at positions around the heart and interconnected to one another.
1. A method for delivering a cardiac support device to a patient, including:
placing a plurality of compliant and rupturable cardiac support device sections in an undeployed state adjacent to a side of a lower portion of a heart; and
deploying the device sections by acting on the sections and causing the device sections to rupture and expand to a generally flattened state; and
interconnecting the deployed device sections to form a cardiac support device.
2. The method of claim 1 wherein each of the sections is separately delivered and placed on the heart.
3. The method of claim 1 wherein edges of the compliant sections overlap.
4. The method of claim 1 wherein interconnecting the compliant sections includes adhesively interconnecting the sections.
5. The method of claim 1 wherein interconnecting the compliant sections includes mechanically interconnecting the sections.
6. The method of claim 1 including placing and interconnecting compliant sections around an entire lower portion of the heart.
7. The method of claim 1 wherein deploying the device sections includes inflating undeployed sections with gas and forcing the sections to rupture.
8. The method of claim 1 wherein deploying the device sections includes mechanically acting on the undeployed sections to cause the sections to rupture.
9. The method of claim 1 wherein deploying the sections includes causing the sections to self-expand.
10. The method of claim 1 performed by minimally invasive surgical techniques.
11. The method of claim 1 and further including insufflating a pericardial space around the patient's heart with gas before placing and interconnecting the sections.
12. A system for deploying a cardiac support device, comprising:
a plurality of compliant and rupturable sections in an undeployed state configured to be interconnected with other compliant and rupturable sections in an undeployed state to form a cardiac support device; and
a delivery means for holding the one or more compliant sections in the undeployed state for insertion into a pericardial space adjacent a heart, and including a deployment means for rupturing the sections and causing the compliant sections to take a generally flattened deployed configuration at which they can be interconnected to one another around the heart.
13. The system of claim 12 wherein:
the compliant sections include balloon segments sections; and
the deployment means includes a source of pressurized gas for rupturing the compliant sections.
14. The system of claim 12 wherein the compliant sections further include elements for biasing the sections from the collapsed state to the deployed configuration.
