A common breast reconstruction technique is tissue expansion, which involves expansion of the breast skin and muscle using a temporary tissue
expander. After a few months, the
expander is removed and the patient receives either microvascular flap reconstruction, or the insertion of a permanent breast implant.
The company's AeroForm Tissue
Expander System is used in patients undergoing two- stage breast reconstruction following mastectomy.
The new beam
expander is interchangeable with Qioptiq's previous model (2x-8x).
Using the PI7C1401, four low-speed ports can be aggregated into a single channel and, by combining multiple quad port
expanders, a host processor can control up to 56 transceivers through a single I2C/SPI interface.
In one of these two sites, the
expander was expelled due to crack formation of the silicon shell as a result of handling the body of the
expander with the dental tweezer (Figures 8(a)-8(c), "Case 2").
A modified small scale internal combustion Wankel engine is used as a steam
expander. The flow through the Wankel engine is uniflow, and continuous generation of torque is available with three expansions per cycle of the rotor.
If not, follow the same process as suggested to align the
expander: loosen the seating stem, seat a bullet, and, holding the works captive, tighten the stem-locking nut.
The second stage consisted of the removal of the tissue
expander and reconstruction of the defect.
