Abstract: An expandable introducer sheath for passage of implant delivery catheters, such as catheters for delivery of prosthetic heart valves. The expandable sheath balances the amounts, shapes and positions of various stiff and elastic structures in the sheath to selectively program the expandability and buckling stiffness of the sheath.

The combination of stiff and elastic wall portions allow for torque and push strength to advance the expandable sheath while at the same time accommodating temporary expansion. The expandable sheath can also be reinforced with a tubular layer of braided fibers or a stent structure for additional strength. Other embodiments include selective use of slots or gaps at the distal end of a stiff wall portion to enhance expandability and distribute strain.

Abstract: Embodiments of the present invention disclose a reference signal sending/receiving method, a terminal device, and a network device. The terminal device determines transmit power of a reference signal of the terminal device, where the transmit power is related to a quantity of unavailable time-frequency resources in a transmission unit in which the reference signal is located; and transmits the reference signal based on the transmit power.
