Vascular: Enhancing vascular procedures

Currently, more endovascular procedures are used to treat diseases of the neurovasculature, carotid arteries and the lower extremities. As a result, clinicians need sophisticated devices to navigate small, tortuous anatomy. Our materials are adding lubricious coatings to catheters necessary for performing these procedures.

Navigating tortuous anatomy

For many vascular conditions, minimally invasive approaches are becoming an alternative to open surgery. The evolution of these techniques calls for therapies that are easier to perform, with lower profile devices. Our strong fiber technology with high tear and abrasion resistance enables device manufacturers to reduce the profile of their devices – such as balloon catheters, neurology catheters and covered stents. Stronger, smaller devices are easier to manipulate inside the body, simplifying navigation through tortuous anatomy to small or difficult to reach spaces.

DSM coating technology and materials further help manufacturers make smaller, more lubricious devices. This is especially helpful in stent placement, atherectomy, and balloon angioplasty procedures, where the coating on a device gives clinicians easier access to probe the vascular frontier. These material benefits also apply to vein grafts, where materials need to be clot-resistant and easy to suture; or in drug delivery via catheter or balloon, to prevent restenosis.

Helping prevent stroke

Stroke represents one of the most serious causes of mortality and morbidity in the world. Carotid artery stenting is becoming an accepted treatment for many patients at risk. DSM plays a role by providing polymers to medical device manufacturers. These polymeric materials can be incorporated into the design of a device, such as the coating on a stent delivery system.

Materials for meeting challenges

The challenges that face endovascular surgeons are vast because of the complexity of the body’s network of vessels. It’s a challenge DSM welcomes. In fact, we rely on experience and know-how to customize material solutions for medical device manufacturers’ requirements that help clinicians overcome many of these challenges – and help potentially save the lives of patients.
