A medical device engineered for implantation, specifically within a ventricular septal defect (VSD), utilizes a self-expanding frame composed of nitinol. The design integrates two primary structural elements: a slotted tube section and a woven section. The slotted tube portion is characterized by precisely cut slots that allow for radial expansion and flexibility. The woven component contributes additional scaffolding and structural integrity to the device.
This type of implant offers several advantages in the context of VSD closure. The self-expanding nature of the nitinol frame facilitates secure anchoring within the defect, minimizing the risk of migration. The combination of the slotted tube and woven sections aims to balance radial force, conformability to irregular defect shapes, and long-term durability. Historically, the development of such devices represents an evolution in minimally invasive approaches to structural heart disease, providing an alternative to open surgical repair in select patient populations.
