  • Patent number: 10806612
    Abstract: The present invention relates to a stent that uses a shape memory alloy wire, the stent being an expansion device installed on a part of a body lumen, which is constricted, or which has been constricted, so as to widen the passage of the lumen in response to the lesion part. The purpose of the present invention is to provide a method for manufacturing a stent using a shape memory alloy wire such that the stent maintains a high degree of conformability in a bent portion of a body lumen in which the same is inserted while substantially improving rigidness and durability against continuously applied fatigue, a stent manufactured thereby, and a jig for manufacturing the same.

  • Patent number: 10799347
    Abstract: An implantable prosthetic valve includes a radially collapsible and radially expandable annular frame. The frame includes an annular main body sized to be implanted within a native mitral valve annulus. The frame also includes an atrial sealing member coupled to and extending radially away from the main body. The atrial sealing member is sized to extend over tissue of the native mitral annulus within a left atrium to reduce paravalvular leakage. The atrial sealing member includes an inner zig-zag portion and an outer zig-zag portion. The inner zig-zag portion and the outer zig-zag portion are connected to the main body portion only via a fabric to enhance flexibility of the atrial sealing member relative to the main body. The prosthetic valve also includes a valve member disposed within an interior of the frame.

  • Patent number: 10786348
    Abstract: A method and system provide an ophthalmic lens including a lens body having a chamber therein, a reservoir module coupled with the lens body and an optical fluid. At least part of the lens body is flexible. The reservoir module includes a reservoir and a heat sensitive portion bordering the reservoir. The reservoir has a reservoir volume and is fluidically connected with the chamber. The heat sensitive portion has a shape responsive to a temperature of at least forty five degrees Celsius such that the reservoir volume changes in response to at least part of the heat sensitive portion reaching the temperature. The optical fluid resides in the chamber and the reservoir. A change in the reservoir volume flows a portion of the optical fluid between the reservoir and the chamber such that the flexible portion of the lens body undergoes a shape change corresponding to a base power change.

  • Patent number: 10758380
    Abstract: The present disclosure provides stents, particularly self-expanding stents, useful for the GI tract, and more particularly, useful for treating esophageal strictures. The stents provided herein include a medial region and proximal and distal cuffs having external diameters greater than the medial region diameter when the stent is in the deployed state. The medial region comprises an open weave wire construction. An elastomeric coating circumscribes the medial region, while the may be an extension of the wire construction or separate elements. Preferably, the cuffs have a textured surface for contact with the esophageal wall tissue to resist stent migration. The elastomer coated medial region provides a barrier to tissue ingrowth, and has an enhanced radial restoring force to maintain an open passageway in a body lumen. Optionally, the stent includes an exterior sheath with a surface pattern, to which the stent couples.

  • Patent number: 10751167
    Abstract: An intraocular lens focuser (114) to be implanted in a human eye includes a resiliently deformable force applicator (140) to apply a focussing force to an accommodating intraocular lens and an attaching portion configured to enable attachment of the lens focuser in the eye. The force applicator is configured such that, in use, when a ciliary muscle of the eye is relaxed to place the accommodating intraocular lens in a distance vision condition, the force applicator is in a deformed condition and when the ciliary muscle contracts to place the accommodating intraocular lens in a near vision condition the force applicator resiles towards a relaxed non-deformed condition to at least assist in placing the accommodating intraocular lens in the near vision condition.

  • Patent number: 10736734
    Abstract: An accommodating intraocular lens (AIOL) for implantation within a capsular bag of a patient's eye comprises first and second components coupled together to define an inner fluid chamber and an outer fluid reservoir. The inner region of the AIOL provides optical power with one or more of the shaped fluid within the inner fluid chamber or the shape of the first or second components. The fluid reservoir comprises a bellows region with one or more folds of the bellows extending circumferentially around an optical axis of the eye. The bellows engages the lens capsule, and a compliant fold region between the inner and outer bellows portions allows the profile of the AIOL to deflect when the eye accommodates for near vision. Fluid transfers between the inner fluid chamber and the outer fluid reservoir to provide optical power changes when the eye accommodates.
