Abstract: Features for a powered prosthetic thumb are described. The thumb provides for rotation of a digit that mimics the natural movement possible with a sound thumb. The thumb may attach to a full or partial prosthetic hand or socket on a residual limb. The thumb may include an upper assembly, including a prosthetic thumb digit, rotatably attached to a mount about a pinch axis and a lateral axis. The digit may rotate about only the pinch axis, only the lateral axis, or both the pinch and lateral axes simultaneously. A first actuator may actuate to cause rotation of the digit about the pinch axis. A second actuator may actuate to cause rotation of the digit about the lateral axis. The first and second actuators may be actuated together at appropriate speeds to cause rotation about both the pinch and lateral axes simultaneously. A swaying chassis may be rotatably connected with the upper assembly and a lower assembly about various offset axes to provide for rotation about the lateral axis.

Abstract: Low profile, self-expandable, blood flow restrictors include a hollow channel open at axial ends to allow blood flow through the restrictor installed in a blood vessel. The channel may include a mesh and have a narrowing, or sandglass, profile to reduce blood flow. The sandglass shape is in a central portion of the channel and may be surrounded by a blocking coating impermeable to blood flow or a suture that dissolves over time. The mesh may be formed of a memory alloy. Restrictors include a retrieval connector at an end that is permeable to blood flow and permits attachment for restrictor positioning with a catheter.

Abstract: The present invention relates a vascular prosthesis for a blood vessel of a patient, which has the following: a hollow-cylindrical main body with a main lumen extending therein, an also a multiplicity of stent rings, which are not connected to one another, are arranged spaced apart one behind the other in the longitudinal direction of the vascular prosthesis and running around in a meandering formation. The vascular prosthesis also has four side branches, which extend distally into the main lumen from fenestrations in the prosthesis material lying between the stent rings.

Abstract: A method of sutureless intrascleral haptic-hook lens implantation which improves the fixation process of the lens haptics, allowing the lens haptics to be bent and folded back into the vitreous cavity to generate a better stability, avoiding the complication of intrascleral fixation haptic slippage, meanwhile forming a sclera lamellar groove between two adjacent scleral incisions to bury the lens haptics. The method may be adapted to patients in need of intraocular lens implantation without sufficient capsular support, such as aphakia, intraocular lens, lens dislocation, etc. This method enhances the stability and centrality of the lens, the surgical procedures are simple and easy to master, which reduces the operation time.

Abstract: The techniques of this disclosure generally relate to a variable permeability layered prosthesis including an impermeable outer layer and a permeable inner layer. The impermeable outer layer is well suited to seal a dissection opening of a dissection. The permeable inner layer allows fluid to enter into a dead space between the impermeable outer layer and the permeable inner layer. The fluid in the dead space coagulates in the dead space providing a media for tissue growth into the prosthesis. The ability of tissue to integrate into the prosthesis provides biological fixation of the prosthesis in vessels and prevents endoleaks and migration of the prosthesis.

Abstract: Stent graft consisting of a stent (1) comprising a plurality of ring segments (3, 4) having a meandering configuration arranged side by side and connected with each other by connecting webs (6), and at least one membrane (2) covering the entire outer side of the stent (1), being wrapped inwards around the ends of the stent and fixed between loops of ring segments (4) and connecting webs (6) that join the adjacent ring segments (3, 4) with each other, wherein the membrane (2) is fixed between at least two loops of the second ring segment (4), viewed from the ends of the stent (1), and the connecting webs (6) to the neighboring terminal ring segment (3).

Abstract: A femoral augment, or set of augments, for use with a knee joint prosthesis, where the femoral augment includes a main body portion, an aperture formed within the main body portion and extending in a generally distal/proximal direction, and a pair of legs extending outwardly from said main body portion in a generally posterior direction. In the preferred embodiment, the aperture is configured to receive a stem extension implant, and to allow it to pass through. Additionally, the legs of the femoral augment are preferably configured to be seated proximal of a proximal side of a pair of condylar portions of a femoral component of a knee joint prosthesis. The present invention is intended for situations in which the distal portion of the femur is defective, and it provides a method and devices that allow for preservation of healthy peripheral bone, while still providing the necessary augmentation to the distal portion of the femur.

Abstract: Disclosed herein is an intravascular stent for being implanted into blood vessels and a method for manufacturing the same. The intravascular stent is woven by at least one weaving wire, and the stent is in a tubular structure. The at least one wire has an even number of free ends, and the free ends of the at least one wire are aligned and jointed together with each other, which have cutting portions. The cutting portions of the two free ends that are aligned and jointed with each other match each other to make the two free ends be engaged into a joint portion with a diameter identical to that of the wire. The intravascular stent has seamless connection, and the distribution of radial force and axial force of the free ends is uniform, leading to convenience for laser welding. Moreover, the intravascular stent has great flexibility, excellent operability and perfect appearance.

Abstract: A method of corneal implantation with cross-linking is disclosed herein. In one or more embodiments, the method includes the steps of: (i) forming a flap in a cornea of an eye so as to expose a stromal tissue of the cornea underlying the flap; (ii) pivoting the flap so as to expose the stromal tissue of the cornea underlying the flap; (iii) inserting an implant under the flap so as to overlie the stromal tissue of the cornea; (iv) applying laser energy and/or microwaves to the implant in the eye so as to modify the refractive power of the implant; (v) applying a cross-linking solution that includes a photosensitizer to the implant; (vi) covering the implant with the flap; and (vii) irradiating the implant so as to activate cross-linkers in the implant, and thereby cross-link the implant and the stromal tissue of the cornea surrounding the implant.

Abstract: A needle lattice is used to form openings within a graft material to selectively enhance permeability of a prosthesis for tissue integration therein. The needle lattice may be disposed on, for example, a surface of a roller or press. The needle lattice precisely places openings in any pattern and location, and on any textile that forms the graft material. The needle lattice can be heated to fuse the surrounding material of the openings of the textile to prevent movement of the textiles and to prevent collapse of the openings. All parameters of the openings, including varying density, patterns, and size of each opening, can be controlled, allowing for the opportunity to selectively enhance and optimize the permeability of the graft material in a vessel. The needle lattice can quickly form multiple openings within a graft material, allowing for quick manufacturing of the prosthesis.

Abstract: Described herein are tissue grafts derived from the placental tissue that are reinforced with at least one biocompatible mesh.
