Abstract
A tissue dissecting device, including an inflatable bladder configured to be inserted into a body via an introducer tube in a compact deflated state, and to be inflated to a substantially planar form in a manner which dissects tissue. A method for dissecting tissue, including inserting an inflatable bladder, in a deflated state, via an introducer tube, into a space in a body, and inflating the bladder to a substantially planar form, thereby dissecting tissue. A method for dissecting tissue, including inserting an introducer tube via an incision into a body, inserting an inflatable bladder, in a deflated state, via the introducer tube, into a space in the body, pulling the introducer tube back at least a length of the deflated bladder, inflating the bladder, via a filling tube, to a substantially planar form, thereby dissecting tissue, disconnecting the filling tube from the bladder, retracting the filling tube and the introducer tube from the body. Related apparatus and methods are also described.
