Convertible surgical tissue staplers and applications thereof, having small sizes and high suitability for introduction and delivery through small surgical incisions or cuts, natural orifices, or laparoscopic ports, followed by deployment to full operational configurations. Convertible surgical tissue stapler may be a linear tissue stapler such as endo cutter stapler. Linear tissue stapler includes: elongated body having longitudinal axis; and stapling head, including first and second members, at least one with rows of tissue fasteners. Convertible from delivery configuration, whereby members are consecutively arranged lengthwise, with overall diameter smaller than minimal inner diameter, to deployment configuration, whereby members are juxtapositionally arranged, with overall diameter equal to or greater than minimal inner diameter. Also disclosed are methods of surgically fastening or/and cutting tissue inside a body, for example, using a linear tissue stapler, and of deploying a linear tissue stapler to operational form. |
