Abstract: Provided is a medical device implantation apparatus, comprising: an outer sheath, connected to a first portion of a handle and extending from a proximal end to a distal end; a middle sheath, the middle sheath being arranged in the outer sheath, and the middle sheath being connected to a second portion of the handle; an inner sheath, the inner sheath being allowed to pass through the middle sheath, the inner sheath being connected to a third portion of the handle, and the inner sheath being movable relative to the outer sheath; outer casings, with at least two outer casings being provided, and a distal end of the inner sheath being respectively fixedly connected to the outer casings; and a medical device, arranged around the inner sheath and partially accommodated in the outer casings.

Abstract: An intraluminal stent (1) and a preparation method therefor are provided. The intraluminal stent (1) includes at least one sub-stent. The sub-stent includes at least a first wire (4) extending along a first spiral direction and at least a second wire (5) extending along a second spiral direction, and the first wire (4) and the second wire (5) extend in different directions to form several wire intersection points. The intraluminal stent (1) has several wrapped portions (2) to wrap two corresponding wire tail ends. A wrapping connector (3) is disposed at a periphery of the wrapped portion (2). Two end portions of the wrapping connector (3) are firmly connected to regions corresponding to two ends of the wrapped portion (2). The two wire tail ends of the wrapped portions (2) are wrapped by using the wrapping connector (3). The stent (1) is less harmful to intraluminal tissues and a relatively strong tensile resistance.
