Minimally invasive cardiac procedures require surgeons to perform precise suture knot placement within confined operative spaces and limited visualization. Traditional techniques can be difficult to control in these environments, increasing procedural complexity and variability, particularly during critical steps such as neochord placement.

An intracorporeal knot placement assist device was developed to enable accurate and controlled suture knot positioning in minimally invasive cardiac procedures. The device incorporates a low-profile tip designed for precise placement at the target site, along with a suture loop mechanism that enhances grip and tension control during knot delivery. Its ergonomic design supports consistent handling and reduces the effort required to maintain stable positioning within confined spaces, helping surgeons achieve reliable knot placement with improved control and efficiency.
