In the most delicate and important procedures, you need to know the medical devices you’re counting on are high quality and dependable. Proterial Cable America High-Performance Medical Solutions (PCA-HPMS) is consistent with our ability to use engineered materials and precise manufacturing to make components that will be reliable in crucially important interventions.
The Middle Sheath used in Endoscopic Vein Harvesting is a great example of the ingenuity PCA-HPMS puts into our products. Read on to learn more about the Middle Sheath, its importance, and applications.
When someone has high blood pressure, high cholesterol or has one of several other risk factors – including smoking – plaque can build up around the heart and cause a condition called atherosclerosis, where an artery is clogged or narrowed. When this happens, not enough blood gets to the heart and the sufferer experiences angina, or chest pains. If left untreated, this can further lead to heart attack.
When a doctor discovers atherosclerosis, they plan on heart bypass surgery, where the blocked or narrowed artery is closed, and a newly implanted vein serves as a detour for blood to sufficiently reach the heart.
Endoscopic Vein Harvesting (EVH) is the step before heart bypass surgery where a vein is removed from another part of the body for implantation in the chest.
Although veins can be harvested from several places, the most commonly removed vein is the saphenous vein in the leg. The reason for removing the saphenous vein is that much like the pinky toe or tonsils, the saphenous vein no longer has a major importance and removing it does not influence the leg’s ability to function.
The procedure involves:
An EVH endoscope is made up of multiple components designed to enhance surgical precision:
During EVH, the Middle Sheath plays a vitally important role. It is of the utmost importance that the vein that is harvested is handled with precision and care, and the middle sheath is part of the main device rod making sure that happens.
After the incision is made and the tunnel is created, the device rod is inserted which includes layers of tubing with the middle sheath fit in the center. These work together to create a barrier between the vein and the leg tissue, so tools can maneuver under the skin and the vein can be extracted safely.
The PCA-HPMS team understands the importance of the middle sheath. This is why our middle sheath is manufactured as a single-lumen extrusion made from high-performance copolymer resin. Using advanced material means that our middle sheath offers the flexibility and durability needed for EVH while remaining precise enough for minimally invasive procedures.
Manufactured in ISO-certified cleanrooms, every middle sheath we create is ready to support the critical demands of EVH surgeries while meeting stringent medical standards.
For years, PCA-HPMS has been a trusted partner in the medical device industry, engineering high-quality components for life-saving procedures like EVH.
With innovative and dependable solutions like the middle sheath, PCA-HPMS is committed to advancing patient care and surgical success. Contact our team to learn how PCA-HPMS can support your medical device innovations.
