Stretchy Implants Could Stick to Arteries to Treat High Blood Pressure
AI-summarised brief · reviewed before publication
Researchers at Penn State have developed a new class of 3D-printed bioelectronics called CaroFlex to treat high blood pressure. The device is made of soft, stretchy materials and an adhesive component that helps it stick to biological tissue. CaroFlex was tested in a rodent model and relieved hypertension while causing less damage to surrounding tissue. The device uses electrical signals to modulate the body's natural response systems, specifically the baroreceptor reflex. It can be stretched out over twice its original size before breaking and showcases strong adhesion. CaroFlex reduced blood pressure by over 15% on average in rat models.
💡 Why It Matters
- · CaroFlex addresses the limitations of existing rigid bioelectronics that can cause tissue damage.
- · Its soft and stretchy design better matches the mechanics of the tissue, allowing for safer and more effective treatment of drug-resistant hypertension.
