The present invention relates to an occluder, comprising a meshed occlusion body provided with a cavity, and a proximal hub, as well as a locking member and a stopping member both of which are located in the cavity. The distal end of the locking member is connected to the distal end of the occlusion body. The stopping member is disposed at the proximal end of the locking member. The proximal occluder head is provided with a locking hole in communication with the cavity. An occlusion device comprises the occluder, a hollow delivery' mechanism and a traction member. The distal end of the traction member is detachably connected to the proximal end of the locking member of the occluder after extending through the distal end of the delivery' mechanism. The occlusion device has a simple locking structure, and simplifies the manufacturing process and the locking operation.

A Z-shaped braided stent capable of being implanted into a human organ. The Z-shaped braided stent comprises: a first tubular wire mesh having N braided rings and formed by continuously braiding first braid wires (I) in a Z shape, each braided ring of the first tubular wire mesh having a plurality of first bending points (A) formed by bending the first braid wires (I) and distributed at intervals; and a second tubular wire mesh having N braided rings and formed by continuously braiding second braid wires (II) in a Z shape, each braided ring of the second tubular wire mesh having a plurality of second bending points (B) formed by bending the second braid wires (II) and distributed at intervals. By hooking the first bending points (A) with the second bending points (B), the second tubular wire mesh and the first tubular wire mesh are connected together to form the Z-shaped braided stent. The braided stent can be subjected to axially deformable compression, but axially basically non-deformable stretching.

This disclosure concerns medical devices, such as catheters and implantable devices, having radially adjustable features. More particularly, the catheters and implantable devices can radially expand and contract to perform various functions within the body. Expansion and contraction can be performed by a radially adjustable structure mounted on the medical device. For example, a medical device can include an body configured for in vivo introduction, a strip attached to the body and rolled into a ring such that layers of the strip radially overlap each other, and at least one motor actuatable by electrical energy to move the radially overlapping layers of the strip relative to one another and change a diameter of the ring and the body.

A prosthetic implant includes a circumferentially adjustable sealing collar and a rotatable sealer gear. The sealing collar has a central longitudinal axis. The rotatable sealer gear is coupled to and disposed within the sealing collar and configured to adjust the circumference of the sealing collar. The sealer gear is radially offset relative to the central longitudinal axis of the sealing collar. Rotating the sealer gear in a first direction relative to the sealing collar circumferentially expands the sealing collar. Rotating the sealer gear in a second direction relative to the sealing collar circumferentially contracts the sealing collar.

An endoluminal support structure includes strut members interconnected by swivel joints to form a series of linked scissor mechanisms. The structure can be remotely actuated to compress or expand its shape by adjusting the scissor joints within a range of motion. In particular, the support structure can be repositioned within the body lumen or retrieved from the lumen. The support structure can be employed to introduce and support a prosthetic valve within a body lumen.
