An implant delivery device suitable for delivery of breast implants features a reusable design that can be autoclaved to sterilize between uses. External fluid pressure is selectively delivered to a housing with the implant inside and can be regulated by the surgeon. The application of fluid pressure can be paused with the already applied pressure retained in the housing giving mechanical advantages for easier force application by the surgeon for enhanced control of the position of the implant within the housing and as it exits the outlet of the housing. The housing can be transparent to aid in observing the implant position and orientation as it moves through the housing. The outlet tip can be slant cut to allow for a fixed opening of the incision before delivering the implant to the surgical site. The housing cover is configured for rapid attachment with a seal that is amenable for autoclaving.

Tissue expanders and methods of their manufacture and use are disclosed herein. A tissue expander shell according to the present disclosure may include a shape and topography that facilitates uniform or substantially uniform expansion and contraction of the tissue expander. In at least one example, the shell may include a series of topographical features, such as ridges, grooves, channels, valleys, canals, protrusions, pleats, creases, or folds. In some embodiments, these features may have a curved or wavy cross sectional profile. For example, the shell may include a series of concentric curved ridges.

The present disclosure provides tissue products produced from extracellular tissue matrices. The tissue products can include acellular extracellular matrices including combinations of different tissue types. The combination can harness various properties of the different tissues to provide improved composite structures with desired mechanical and/or biologic properties.
