Methods of controlling the degradation profile of a biodegradable stent scaffolding are disclosed. Disclosed methods include controlling features of the degradation profile including the time to loss of radial strength and the degradation time of the stent.

The invention discloses a solid wood bending processing method with the directional bending function. The solid wood bending processing method comprises the following steps: marking a to-be-bent position on a wood blank, adopting a waterproof material to wrap the part not need to be bent tightly, then, enabling the water content of the wood to be within the proper range, softening and bending thewood, and carrying out drying, bending setting and water content equalization treatment on the wood to obtain a finished product. With adoption of the solid wood bending processing method, directionalbending of solid wood is realized, the size loss ratio and the strength loss ratio of the solid wood are greatly reduced, and the processing quality of the bent solid wood can be remarkably improved.
