​

Indications for Use

U.S.
Outside U.S

The COR-KNOT® MIS DEVICE and COR-KNOT MINI® DEVICE are indicated for use in the approximation of soft tissue and prosthetic materials, used in conjunction with either A) LSI SOLUTIONS® specified 2-0 Polyester or 2-0 Polypropylene suture and a COR-KNOT® QUICK LOAD® UNIT, or B) 2-0 Polyester, 2-0 Polypropylene, or 3-0 Polypropylene suture and an INTRA-KNOT™ QUICK LOAD® UNIT.

The COR-KNOT® DEVICE used in conjunction with LSI SOLUTIONS® specified 2-0 polyester suture and a COR-KNOT® titanium fastener is indicated for use to fasten and trim suture in general and cardiovascular surgical applications. 

Features & Benefits

The COR-KNOT® DEVICE has several key features and benefits that distinguish it as the leading automated suture fastening system.

COR-KNOT® FASTENER

provides a strong, secure and safe alternative to hand-tied knots.

​

​

DEVICE OPTIONS

The 4mm shaft of the COR-KNOT MINI® and the 5mm shaft of the COR-KNOT® MIS allow the surgeon to perform MIS and open procedures.

​

COR-KNOT® QUICK LOAD® UNIT

expedites the loading and reloading of a COR-KNOT® FASTENER into the COR-KNOT® DEVICE.

​
Unparalleled automated reliability
Clinically Proven. Over 375 thousand cardiovascular patients with 6.2 million fasteners over 12 years in 64 countries
Facilitates Minimally Invasive Cardiac Surgery
Ergonomic. Fun and easy to use with tiny shaft, certainly smaller than fingers
Short Learning-Curve making COR-KNOT® quickly and easily learned
Single Squeeze. Automatically crimps and trims; dramatically reduces instrument exchanges
Suture Tail Control. Now you can readily orient suture tails away from leaflets
Tight Approximation. Enables simultaneous suture tensioning and prosthetic compression for scientifically demonstrated secure apposition
Consistent Knot Strength. Delivers over 4kg of holding force every time
Fast. Multiple studies demonstrate an average savings of more than 15 minutes in aortic cross-clamp time

Device Anatomy

COR-KNOT® DEVICE

The COR-KNOT® MIS DEVICE is available with a 31cm length, 5mm diameter shaft, and the COR-KNOT MINI® DEVICE is available with a 17cm length, 4mm diameter shaft.

​

COR-KNOT® QUICK LOAD® UNIT

A COR-KNOT® QUICK LOAD® UNIT is used to load a COR-KNOT® FASTENER into the COR-KNOT® DEVICE. Each COR-KNOT® QUICK LOAD® UNIT provides one sterile COR-KNOT® FASTENER held in a customized loading unit consisting of a purple target, a wire snare and a blunt curved handle.

Made from medical grade titanium, a COR-KNOT® FASTENER is a mushroom-shaped hollow sleeve, which is crimped by the COR-KNOT® DEVICE to fasten together segments of suture.
