Devices and methods for stabilizing tissue within a patient's body. Such a device is adapted to assume a reduced configuration and an operating configuration. The device assumes the reduced configuration for passage through a small opening to deliver a working end of the device to a site of the tissue to be stabilized. Such a device may include first and second contact members that are mounted for rotation, with each having a contact surface adapted to contact a surface of the tissue. When the device is in the operating configuration, a largest cross-sectional dimension of the contact members may be greater than a largest dimension of an opening through which the contact members were passed. However, when in the reduced configuration, largest cross-sectional dimension of the contact members is less than the largest dimension of the opening. |
