Abstract
Guidewire exchange systems, devices and methods, for positioning and actuating surgical devices in a desired position between two tissues in a patient's body are described. A guidewire may be coupled to a surgical device for positioning and actuating (e.g., urging against a target tissue). The guidewire may be exchanged between different surgical devices during the same procedure, and the guidewire and surgical devices may be releaseably or permanently coupled. The surgical device generally includes one or more guidewire coupling members. A system may include a guidewire and a surgical device having a guidewire coupling member. Methods, devices and systems may be used in open, less-invasive or percutaneous surgical procedures.
