Source: Lee, Y., et.al. Transplantation of Schwann Cells Inside PVDF-TrFE Conduits to Bridge Transected Rat Spinal Cord Stumps to Promote Axon Regeneration Across the Gap. J. Vis. Exp. (2017)This video demonstrates the use of a piezoelectric polymer conduit seeded with Schwann cells to promote axon regeneration in a transected rat spinal cord. The conduit provides structural guidance, while its bioelectric properties stimulate neurite outgrowth. Schwann cells within the conduit secrete...

This is a case report of a patient with congenitally corrected transposition of the great arteries (CCTGA) who received a total artificial heart (TAH) as a bridge to heart transplant. The TAH was successfully implanted with modifications to accommodate the patient's congenitally malformed heart.

To improve our knowledge of cellular and molecular neotissue formation, a murine model of the TEVG was recently developed. The grafts were implanted as infrarenal vena cava interposition grafts in C57BL/6 mice. This model achieves similar results to those achieved in our clinical investigation, but over a far shortened time-course.

Dual-chamber implantable cardioverter-defibrillators (ICDs) may improve detection of atrial fibrillation as well as differentiation of tachycardias. However, this advantage is undermined by complications associated with the second electrode, which is required in conventional dual chamber devices. Therefore, BIOTRONIK has developed a new electrode called the LinoxSMART S DX that, when used in conjunction with the Lumax DX ICD, offers dual-chamber detection without the risks associated with the...
FAQs
Diameter and material are matched to the intended anatomical connection and the role the conduit must perform. A suitable diameter supports blood passage through the reconstructed route, while the selected biological or synthetic material must be appropriate for placement and healing tissues. This matching helps the implant function as planned rather than merely bridge two structures.
The reconstructed pathway can address more than interrupted circulation. Depending on where it is placed, the conduit may reestablish blood flow between structures, provide an outflow tract, separate abnormal flow pathways, or substitute for a damaged vessel. Thus, its anatomical position determines the problem being corrected and the outcome clinicians seek.
Sutures do more than hold the tube in place. They secure each conduit end to its intended connection so blood can enter and leave the implant through the planned route while surrounding tissues heal. Reliable attachment is therefore central to maintaining a continuous pathway during the early period after reconstruction.
At a general level, implantation begins with identifying the intended anatomical connections and selecting a conduit with an appropriate diameter and material. The tube is then positioned between those structures, and both ends are secured with sutures. This sequence creates the planned route for blood while the surrounding tissues undergo healing.
Clinical use depends on the defect or vessel problem being addressed. In congenital heart repair, a conduit can contribute to outflow-tract reconstruction or help separate abnormal flow pathways. In vascular bypass, it can replace or route around a damaged vessel. These applications share the goal of restoring an effective circulation pathway.
Successful implantation is not judged only by placement at surgery. Follow-up must consider whether the conduit continues to function and integrates with surrounding tissues. Because later revision may be needed, ongoing surveillance is part of management, particularly when the reconstructed pathway must remain effective over time.
