Abstract
Guidewire-deliverable devices and methods of using the devices for separating adjacent layers of tissue and for delivering a surgical prosthesis to an operating site. A guidewire-delverable cannula provides an elongate window for accessing the operating site with a tissue-separating device. The tissue-separating device may include one of several types of an inflatable balloon or a tissue-dissecting member. The tissue-separating balloon may simultaneously deliver the prosthesis during tissue separation and may further be detached to remain with the prosthesis over the operating site. Alternatively, the prosthesis may be separately provided after the adjacent layers of tissue have been separated.
