The present invention relates to a biodegradable stent and a shape memory extending method thereof. According to an exemplary embodiment of the present invention, radial force of a biodegradable stent may be largely increased through the shape memory extending method of the biodegradable stent and the number of cracks may be decreased after crimping and stent inflation.

Biodegradable stent and shape memory expanding method therefor

Disclosed herein is a battery pack including (a) a battery cell array comprising two or more battery cells, each of which has an electrode assembly of a cathode/separator/anode structure disposed in a battery case together with an electrolyte in a sealed state, arranged in the lateral direction, (b) a protection circuit module (PCM) including connection terminals connected to electrode terminals of the battery cells by resistance welding, metal plates to electrically connect the battery cells to each other, and a protection circuit to control an operation of the battery pack, the PCM being connected to the upper end of the battery cell array, and (c) a pack case in which the battery cell array and the protection circuit module are disposed, wherein electrical connection regions between cathode terminals of the battery cells and the protection circuit module are configured to have a structure in which conductive plates attached to the tops of the respective connection terminals of the protection circuit module are welded so that the conductive plates surround the respective cathode terminals of the battery cells.
