Abstract
A surgical guidewire device includes an outer tube and a guide needle. The outer tube has a needle tip formed at a tube distal end of the outer tube. The guide needle is movably disposed in the outer tube and has a needle eye structure. When the surgical guidewire device is in use, a suture extends through the needle eye structure, and is carried through the outer tube along with the needle eye structure as the guide needle is moved relatively toward the tube distal end and then away from the outer tube.
Claims8
A method for passing a tissue fixation material through a surgical system, the method comprising:
- positioning a tissue fixation material in a needle eye structure, the needle eye structure formed at a proximal end of a guide needle;
- with the tissue fixation material in the needle eye structure, elastically compressing the needle eye structure and moving the guide needle in a distal direction to pass the tissue fixation material in the distal direction into an outer tube in a first incision in a patient;
- moving a hooking device into a second incision in the patient;
- and
- positioning the hooking device such that the tissue fixation material and the outer tube are within a hook at a distal end of the hooking device.
