Our SynTissue brand straight artery designer allows you to build straight arteries based on your own specifications. These parts may be ordered with integral vascular couplings to allow mating with additional arterial branch segments. Odd sizes (ID increments of 1mm) are available with no additional tooling charges. We now also offer custom constructions with nonstandard of axial and radial wall compliance values as well as variations in chemistry (collagen composition, fiber layout, etc.)
Segments with an ID of 10mm or less employ a muscular arterial structure, while those greater than 10mm employ an elastic arterial structure. Typically, the medial layer occupies a larger portion of the cross sectional area in muscular (distributing) arteries than in elastic (conducting) arteries. Conversely, the elastic medial layer tends to exhibit a lower circumferential modulus than the muscular medial layer.
Basic model construction employs our patented SynTissue brand synthetic human arterial intima, media and adventitia layers. These materials are designed on the basis of physical tests performed on actual living tissue, and each synthetic tissue is validated (tensile modulus, penetration resistance, coefficient of dynamic friction, etc.) under the same physical conditions as the live tissue it is designed to simulate. The resulting synthetic artery responds to puncture, abrasion and balloon dilation just like a real living artery.
Options: Standard finished arteries are 18-20cm in length. In addition to the original standard wall a number of new construction types are available, including transparent, translucent, and silicone-hydrogel composite. If you require custom ID or wall profiles please call and ask to speak to one of our technical sales representatives.
Standard: This is the original construction type, with wall thickness and layer structure determined as a function of ID.
Transparent: This thin-walled construction employs synthetic cornea as a replacement for the media and adventitia, bonded to the standard intima layer.
Translucent: This construction employs synthetic cornea as a replacement for the media and adventitia, including the appropriate fiber mesh in the medial layer, bonded to the standard intima layer.
Composite: This construction employs normal arterial intima bonded to an outer jacket of transparent silicone rubber. These models have a highly lubricious lumen but are nearly indestructible and immune to desiccation.
Extraordinary Features: SynTissue synthetic human tissues made from salt, water, and fiber—which feature the world’s most realistic tactility. SynTissue synthetic human tissues match the acoustical characteristic of real human tissue.
