Absorbable 3D printed implants can be used to reconstruct the nipple with regenerated tissue resulting in improved aesthetic satisfaction. The implants are formed from parallel planes of filaments that are offset and bonded to each other to form macroporous networks (130) with open cell structures comprising cylindrical shapes. The macroporous network (130) may be enclosed by a shell (120) or coating, or may be at least partly filled with a hydrogel. The implants are particularly suitable for use in plastic surgery procedures, for example, to reconstruct the nipple following total mastectomy and breast reconstruction.Absorbable 3D printed implants can be used to reconstruct the nipple with regenerated tissue resulting in improved aesthetic satisfaction.

Aspects of the present disclosure provide a multi-tier semiconductor structure. For example, the semiconductor structure can include a lower semiconductor device tier including lower semiconductor devices, an upper semiconductor device tier disposed over the lower semiconductor device tier and including upper semiconductor devices, a separation layer disposed between and separating the lower and upper semiconductor device tiers, a wiring tier disposed below the lower semiconductor device tier, a lower gate contact extending from a lower gate region of the lower semiconductor device tier downward to the wiring tier, an upper gate contact extending from an upper gate region of the upper semiconductor device tier downward through the separation layer to the wiring tier, and an isolator covering a lateral surface of the upper gate contact and electrically isolating the upper and lower gate contacts. The lower gate contact and the upper gate contact can be independent from each other. Se pueden usar implantes impresos en 3D absorbibles para reconstruir el pezón con tejido regenerado resultando en una satisfacción estética mejorada; los implantes se forman de planos paralelos de filamentos que están desplazados y unidos entre sí para formar redes macroporosas con estructuras de celdas abiertas que comprenden formas cilíndricas; la red macroporosa puede ser encerrada por una corteza o revestimiento, o puede ser llenada por lo menos parcialmente con un hidrogel; los implantes son particularmente adecuados para uso en procedimientos de cirugía plástica, por ejemplo, para reconstruir el pezón después de una mastectomía total y reconstrucción de mamas.
