Abstract: Hemostatic springs and hemostatic seals comprising hemostatic springs facilitate introducing a surgical device into the vasculature of a patient during a surgical procedure. Each hemostatic spring comprises a radial array of spring segments positioned on a circular path about a central axis. Each hemostatic seal is configured to reduce an axial length of the hemostatic spring to constrict the radial array of spring segments to reduce a cross-sectional area of the central passage. Methods include axially inserting the surgical device into the hemostatic seal while compression from the hemostatic seal minimizes fluid leakage. Methods can further include reducing a frictional force of inserting the device into the hemostatic seal by reducing the axial compression to dilate the hemostatic spring.

Abstract: A system includes an inflow loading assembly configured to compress an inflow portion of the implantable medical device as the implantable medical device is advanced through the inflow loading assembly. The system also includes an outflow loading assembly removably coupled to the inflow loading assembly. The outflow loading assembly is configured to partially compress an outflow portion of the implantable medical device during coupling to the inflow loading assembly. The inflow loading assembly includes one or more biasing features that are configured to asymmetrically compress the inflow portion of the implantable medical device.
