Methods and Devices for Passing Sutures Around Anatomical Structures

摘要

Various exemplary methods and devices are provided for passing sutures around anatomical structures. In an exemplary embodiment, a suture delivery device is provided that includes a body portion having a suture delivery member disposed therein and configured to pass a suture around an anatomical structure. The suture delivery member can be movable between a retracted configuration in which the suture delivery member is disposed within the body portion and an advanced configuration in which the suture delivery member extends distally beyond the body portion and assumes an arcurate shape. The arcurate shape can correspond to a shape of the anatomical structure and can extend almost all of the way around the anatomical structure, for example at least around 270° of a circle, thus assisting a user in passing the suture around the anatomical structure without having to manually manipulate the suture delivery device at awkward angles around adjacent tissue.

主权项

1. A suture delivery device, comprising:
a body portion having a lumen formed therein and extending along at least a portion of a longitudinal axis thereof; an actuation member operatively associated with the body portion; and a suture delivery member having a suture retaining feature and being deployable from a distal end of the body portion, the suture delivery member having a distal end that is pre-shaped in an arc that defines at least about 270° of a circle, the suture delivery member being selectively movable by the actuation member from a retracted configuration to an advanced configuration.
