11583283 · 2023-02-21 · ·

A medical device is disclosed and may have a spiral shape structure that can function as a stent, such as a flow diversion stent to treat aneurysms. The medical device may have a spiral shape structure that can function as an occlusive device, for instance to occlude aneurysms. The medical device may include a shape setting structure to selectively adjust the shape of the medical device.

Vessel lining device and related methods

A deployment device for lining a vessel having a housing having a proximal end and a distal end opposite the proximal end, the housing defining a guidewire channel, a tube elongated along a longitudinal axis, the tube having a proximal end and a distal end spaced from the proximal end of the tube along the longitudinal axis, a sheath assembly having a hub removably coupled to the distal end of the housing, and a mesh removably coupled to the tube and positioned along the tube. The tube and the sheath assembly are configured to move along the guidewire and into the vessel through a puncture and release the mesh inside the vessel when at least one of the tube and the mesh is actuated. The device is used as a method of mitigating potential injury or harm to the integrity of the patient's vessel lining.

STENT HAVING REDUCED AXIAL SHRINKAGE UPON RADIAL EXPANSION
20220362043 · 2022-11-17 ·

An intraluminal stent includes pluralities of first and second wire segments made from a soft malleable alloy formed into a cylindrical structure. Each of the wire segments is defined by a series of sinusoidal bends formed over the length of each segment, with the initial unformed length of each second wire segment being larger than that of each first wire segment. Each of the first and second wire segments include the same number of sinusoidal bends with the amplitude of the of the sinusoidal bends of the second wire segments being larger than that of the sinusoidal bends of the first wire segments. Adjacent wire segments are conjoined by welds at apices of each sinusoidal bend to form the cylindrical or tubular structure. The first wire segments can form a center portion of the stent and the second wire segments can be provided at either or both ends of the stent, enabling minimized axial shrinkage when the stent is radially expanded from an initial to an expanded diameter and in which the second wire segment at the terminal end of the stent is caused to outwardly flare significantly relative to the remainder of a radially expanded stent.

Methods for treating abnormal growths in the body using a flow reducing implant

A flow reducing implant for reducing blood flow in a blood vessel having a cross sectional dimension, the flow reducing implant comprising a hollow element adapted for placement in the blood vessel defining a flow passage therethrough, said flow passage comprising at least two sections, one with a larger diameter and one with a smaller diameter, wherein said smaller diameter is smaller than a cross section of the blood vessel. A plurality of tabs anchor, generally parallel to the blood vessel wall, are provided in some embodiments of the invention.

Woven or braided tubular metal construct

Multi-filament microcables are used in place of the traditional monofilament wires as the constituent elements of a woven or braided band. This enhances the function and manufacturability of such bands for various applications, such as orthopaedic applications including sternotomy closures.

Vascular stent

A vascular stent (100) comprises a plurality of wave loops. In its natural state, in two of the wave loops which are adjacent in a group, a part of a wave crest of a lower layer wave loop are in a restrained connection with a part of a wave trough of an upper layer wave loop; the other part of the wave crest of the lower layer wave loop passes through the other part of the wave trough of the upper layer wave loop, and the other part of the wave crest and the other part of the wave trough are in a non-contact mutually-suspended connection. Some of the wave crests and wave troughs of the vascular stent (100) are in the non-contact mutually-suspended connection rather than the restrained connection, so that the maximum flexibility is provided to the stent, and meanwhile, the overall stability of the stent is guaranteed. The stent (100) can maintain a good shape during both implantation and the release process, so that safety during release is ensured.
