A suture punch system is capable of directly passing braided suture through tissue in a simple, one-step process. The system includes three principle components: a malleable needle (20) with braided suture (31) attached, a handheld instrument for grasping tissue and controlling needle placement, and a trocar (70) to supply the force required for needle placement. Needle deformation begins at the tip of the instrument, which preferably includes a curved segment. As the distal tip of the needle pierces the tissue, it continues its radial path through the tissue. When the proximal end of the needle exits from the instrument, the needle is entirely radial in shape and traverses an essentially radial path through the tissue. Non-radial linear or non linear segments may alternatively be used. In one embodiment, the tissue to be sutured is constrained by pressure applied through closure between an upper, moveable jaw the distal portion of the instrument which acts as a fixed jaw (3). The upper, movable jaw (4) contains a shaped passageway which allows the curved needle to pass therethrough during use. Once the needle has passed entirely through the tissue it is ready for retrieval using the jaws of the punch or another instrument. Different needle designs and separate instruments are also disclosed.

L'invention concerne un système de perforation pour suture, capable de passer directement une ligature tressée à travers un tissu en une seule opération simple. Le système comprend trois principaux composants : une aiguille malléable (20) à ligature tressée (31) attachée, un instrument à poignée pour saisir les tissus et commander la mise en place de l'aiguille, et un trocart (70) pour fournir la force requise pour la mise en place de l'aiguille. La déformation de l'aiguille commence à la pointe de l'instrument lequel comprend, de préférence, un segment incurvé. Lorsque la pointe distale de l'aiguille perce le tissu, elle continue son parcours radial à travers le tissu. Lorsque l'extrémité proximale des aiguilles sort de l'instrument, l'aiguille est entièrement radiale en profil et traverse un parcours essentiellement radial à travers le tissu. Des segments linéaires ou non linéaires non radiaux peuvent être utilisés alternativement. Dans une forme d'exécution, le tissu à suturer est contraint par la pression appliquée par la fermeture, entre une mâchoire mobile supérieure, la portion distale de l'instrument agissant comme une mâchoire fixe (3). La mâchoire mobile supérieure (4) renferme un canal profilé, permettant le passage de l'aiguille incurvée durant l'utilisation. Une fois que l'aiguille est entièrement passée dans le tissu, elle est prête à être extraite au moyen des mâchoires du perforateur ou d'un autre instrument. L'invention concerne des conceptions d'aiguilles différentes et des instruments distincts.
