Question

Name a suture device currently on the market that is used in clinical use. Explain the use of the device and mechanism of failure from the device, i.e what are some problems with the device and how can it be solved.

Answer 1

LARIAT Loop Applicator
The LARIAT Loop Applicator is a one-time use suture transfer and deployment equipment which consists of a previously tied polyester suture loop. A central lumen inside the LARIAT Loop Applicator is intended for aspiration and stabilization of tissue. when the delivery of the LARIAT Suture Loop is done the LARIAT Loop Applicator promotes suture installation and knot tying for use in surgical treatments where soft tissue is being ligated with a pre-tied polyester suture.
the possible mechanism of failure can be Soft tissue strength. the suture can cut through the soft tissue to which it is tied. This failure mechanism depends only on the suture, soft tissue and surgical technique.
