A system for ligating a uterine artery in a patient generally includes a suture transfer tool (40), suture transfer darts (60, 61), and one or more sutures (62, 64). The suture transfer tool includes an upper jaw (42) that is pivotally joined to a lower jaw (46). The lower jaw of the tool includes a number of suture capturing pins (54). The suture transfer darts are configured to be tissue piercing and are positionable within the suture capturing pins. Each end of the suture is connected to a suture transfer dart. When operating the tool, the suture transfer darts pierce through the tissue to either side of a patient's cardinal ligament, which contains the uterine artery, and simultaneously present an end of the suture to either side of the cardinal ligament. As such, the suture is in an open loop configuration about the cardinal ligament and can be tied tight to the ligament to occlude the uterine artery.

Un système de ligature d'une artère utérine chez un patient est constitué généralement d'un outil de transfert de fil de suture (40), d'aiguillons de transfert de fil de suture (60, 61)et d'un ou plusieurs fils de suture (62, 64). L'outil de transfert de fil de suture comporte une mâchoire supérieure (42) qui est jointe pivotante à la mâchoire inférieure (46). La mâchoire inférieure de l'outil comporte plusieurs broches de capture de fil de suture (54). Les aiguillons de transfert de fil de suture sont conçus pour percer le tissu et se placent dans les broches de capture de fil de suture. Chaque extrémité du fil de suture est reliée à un aiguillon de transfert de fil de suture. Lorsque l'outil est utilisé, les aiguillons de transfert de fil de suture percent le tissu des deux côtés du ligament de Mackenrodt du patient, qui contient l'artère utérine, et présentent simultanément une extrémité du fil de suture des deux côtés du ligament de Mackenrodt. Ainsi, le fil de suture forme une boucle ouverte autour du ligament de Mackenrodt et peut être noué de manière serrée sur le ligament afin d'occlure l'artère utérine.
