Purpose Successful long-term treatment with mechanical circulatory support (MCS) requires that device-related complications are minimized. Driveline infection (DLI) is a frequent and well-known device-related complication in long-term devices such as left ventricular assist devices (LVAD). We developed a novel way of creating a transcutaneous energy transfer to power MCSs that in the future not only can solve the DLI issue but also improve quality of life for LVAD patients. The novel method is comprised of an implanted energy receiving system and an outer power transmitter system requiring a pierced skin opening. Methods To establish this novel way of powering the MCS a surgical procedure development is ongoing. The required energy receiving, and power transmitting system has been described, patented, and unbundled (Invivopower AB, Gothenburg). During 2020 we performed human cadaver surgeries (n=3) in a pilot trial. We have also developed a surgical procedure in pigs (n=3). The surgical procedure involves forming a pierced skin opening around the implanted energy receiving system. The requirement for the developed implantation method is that it shall be safe, reproducible, simple, and straight forward. Results A preliminary surgical procedure has been developed together with surgical instruments to create the pierced skin opening. The newly designed instruments are comprised of a skin elevator and a suture needle guide. The needle guide is used to hold the pierced skin in place around the implant while the mattress sutures are formed in a precise and reproducible manner. Conclusion This early development has taught us how to perform the surgical procedure. However, human cadaver studies and studies on euthanized animals can´t describe the healing process. To evaluate the healing process of the pierced skin opening an experimental animal model in living animals will be required. |
