Suture clip deployment devices

摘要

Suture clip deployment devices for applying suture clips to sutures are described. Some embodiments can include a generally tubular main body and a vacuum port located at the distal end, a hollow inner body longitudinally slidable within the main body and extending from the main body at its distal end, and a suture recess located in the generally tubular main body. At least one suture clip configured to frictionally fit on an outer surface of the inner body is deployed during use. Clip deployment can occur after a vacuum source is applied to the device so as to draw the suture into the device. The suture lines can be retrieved through the suture recess, and the device can be actuated so as to deliver the suture clip off the delivery device and onto the suture, locking the suture in place.

主权项

1. A method for deploying a suture clips onto a sutures, comprising:
causing a free end of a suture to enter into a distal end portion of an inner lumen of a main shaft of a suture clip deployment device; causing the main shaft to move proximally relative to a handle portion of the suture clip deployment device, a first suture clip mounted around an outer surface of the main shaft and a second suture clip mounted around the outer surface of the main shaft proximal to the first suture clip, such that the first suture clip slides distally off of a distal end of the main shaft and onto the suture such that the first suture clip resiliently secures to the suture, and such that the second suture clip slides toward the distal end of the main shaft; and after the first suture clip is secured to the suture, causing the main shaft and the second suture clip to move distally together relative to the handle portion such that the suture clip deployment device is ready to deploy the second suture clip onto another suture by subsequent proximal motion of the main shaft relative to the handle portion.
