DEVICES AND METHODS FOR TISSUE TRANSPLANT AND REGENERATION

摘要

Devices and methods for transplanting tissue for the purpose of regeneration, for treating a patient having injured myocardial tissue, and/or for improving cardiac function through cell regrowth. More specifically, the devices and methods obviate the need for cellular alteration. The devices comprise a hollow tube (12) with a sharp distal end (11), a stylet (20) that is disposed and movable within the hollow tube, and a stopping device (16) that constrains movement of the stylet. The methods comprise removing intact tissue from a first region of a mammalian organ and implanting the tissue in a second region of the same organ.
