Expandable implant system

摘要

Various embodiments of a sling implant system are provided. Embodiments of the implants can include one or more collapsibility and expandability features or portions adapted to improve introduction and deployment of the implant within the patient. The implants can be folded, collapsed or otherwise reduced in size or construct to fit within a delivery tool or catheter for later expandability upon deployment of the implant.
