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.
La présente invention concerne des dispositifs et des procédés de greffes de tissus dans le but d'une régénération, du traitement d'un patient ayant des tissus myocardiques faisant l'objet de lésions, et/ou d'amélioration de la fonction cardiaque par le biais d'une nouvelle croissance de cellules. Plus spécifiquement, ces dispositifs et ces procédés évitent le besoin d'une altération cellulaire. Ces dispositifs comprennent un tube creux à extrémité distale pointue, un stylet disposé et déplaçable au sein du tube creux et un dispositif d'arrêt qui restreint le mouvement du stylet. Ces procédés comprennent le retrait de tissus intacts d'une première région d'un organe de mammifère et la greffe de tissus dans la seconde région du même organe.
