Gore-Tex Dimensions
Gore-Tex is the most commonly used material for artificial CTs. Gore-Tex has the following specifications. (8)
1. Breaking strength: 1,000 g
2. If suture is clipped: 500 g threshold
Therefore, Gore-Tex sutures are able to replace biological CTs because Gore-Tex can withstand the physiological conditions of the left ventricle.
We anticipate our device will utilize a stiffer material than Gore-Tex. The stiff material will be easier to anchor onto the leaflet and ventricle wall. The device will contain all the compliance needed to allow for normal heart functioning. A stiffer material will be easier to maneuver in the cinching process and will allow for sturdier attachment to our cinching device.

316L Stainless Steel
316L stainless steel is a low carbon steel and is biocompatible and resistant to corrosion. These are the two most important criteria for our cinching device. 316L stainless steel is the traditional choice for bare metal and drug eluting stents. Stents are comparable in size to our device so we believe this is a strong candidate in our materials to consider for the ACT.
§ Biocompatible
§ Strong (Tensile Strength 515 MPa, Rockwell Hardness 95)
§ Durable: corrosive Resistant
§ Easy to machine because of low carbon content
