Claim:
1. A medical apparatus to close a hole in cardiac tissue, the medical apparatus comprising: at least one tool; and a closure device comprising: wherein the closure device is resiliently biased from a first configuration in which a radial size of the central passage has a first dimension toward a second configuration in which the radial size of the central passage has a second dimension, the second dimension smaller than the first dimension, and a portion of the closure device forming at least part of a periphery of the central passage, the at least part of the periphery of the central passage located radially inward from the plurality of barbs at least in the second configuration, and wherein the at least one tool includes a plurality of arms each with respective distal ends and proximate ends, the distal ends engaging the closed band of the closure device, the proximate ends pivotally coupled such that the distal ends are radially spaceable from one another between a retracted configuration and an expanded configuration to move the closure device from the second configuration to the first configuration.
