Provided herein is a system including, in some embodiments, a stent and a catheter. The stent includes a number of filaments arranged to form a tubular body of the stent, a number of microcells forming each filament of the number of filaments, and a port in an end portion of the stent. Each microcell includes a moveable microsurface. The port of the stent may be configured to accept power and control signals for moving the microsurfaces. The catheter may include a cable configured to connect with the port of the stent and provide the power and the control signals for moving the microsurfaces. Moving the microsurfaces may include matching a shape of an anatomical vessel to maintain patency thereof while mitigating stress on the anatomical vessel.

A novel and advantageous implant device and methods for implanting the device are provided. Particularly, novel and advantageous devices and methods for breast reconstruction are provided. More particularly, novel and advantageous devices and methods for breast reconstruction to provide a more realistic form are provided.

A stent for vascular interventions having a hybrid open cell geometry. Variants of the stent include bare metal stents and drug-eluting stents. Embodiments of the stent include end projections for radiopaque markers or a discontinuous partial radiopaque coating on low-stress or low-strain regions of the peripheral stent. The stents of the invention are characterized by having thin walls, nested rows of struts, high expansion ratio, high and uniform radial force over entire diametric size and length of device, crush resistance up to and including about 90% of its fully expanded diameter, high fatigue resistance and high corrosion resistance.

A computer-implemented method for managing enterprise transactions includes creating an overlay to a physical communications network, adding one or more nodes to the overlay, designating one or more nodes of the overlay as super nodes, generating a distributed ledger to store the transactions, and replicating the distributed ledger to all nodes of the overlay. Generating the distributed ledger includes receiving, at the super nodes, transactions from the one or more nodes, assigning, by the super nodes, the transactions to a variable size block, validating, by the super nodes, the variable size block, and linking the validated variable size block to the distributed ledger.

A thoraco-abdominal branch graft prosthesis includes a lumen main graft component that defines a lumen and at least one main graft wall fenestration. An open distal end of the main graft component is tapered and has a smaller diameter than the proximal end of the main graft component. At least one tunnel graft component of the branch graft prosthesis defines at least one tunnel graft fenestration. The tunnel graft component is within the main graft lumen defined by the luminal main graft component. A luminal wall of the tunnel graft component is fixed to the luminal wall of the main graft component. The fenestration of the tunnel graft wall is aligned with the fenestration of the main graft wall. The thoraco-abdominal branch graft prosthesis can be implanted in a patient at a site of a thoraco-abdominal aneurysm.

A kink resistant stent graft includes a graft forming a tube with a central lumen extending from a first end of the tube to a second end of the tube and a stent secured to the graft adjacent the first end of the tube. The graft includes a corrugated inner graft layer forming at least a middle portion of the tube, and an outer graft layer covering the corrugated inner graft layer.

An upgradable intraocular platform system includes (a) a substrate implantable in an eye; (b) an upgrade interface on the substrate for connection of at least one upgrade component for upgrading the platform system; and (c) a controller for controlling operation of the platform system.

An adjustable optic device for providing light field information includes: (a) at least one counter electrode; (b) one or more working electrodes; (c) an insulating framework separating the counter electrode from each working electrode; and (d) an electrolyte medium between the counter electrode and the one or more working electrodes. Each working electrode is reversibly transitionable from a stripped state toward a plated state when a plating charge voltage is applied to induce plating with ions from the electrolyte medium. When in the stripped state, the one or more working electrodes are transparent and present a passage through the optic device for transmission of electromagnetic radiation. When in the plated state, the one or more working electrodes are plated with ions from the electrolyte medium to provide a coded aperture in the passage. The coded aperture has a pattern of subapertures for providing light field information.

Apparatus and methods are provided for flaring a stent deployed within a branch vessel including an ostium communicating with a main vessel, a first end of the stent extending at least partially from the branch. A catheter is provided that includes a first balloon carried on its distal end, and a second balloon that includes a distal section overlying at least a portion of the first balloon and a proximal section. The catheter distal end is introduced into the main vessel and positioned through the ostium and stent into the branch until the first balloon is disposed within the stent. The first balloon is expanded to anchor the stent, and the second balloon is expanded to flare the first end of the stent. Optionally, the first balloon is expanded further, e.g., to expand the stent within the branch body lumen and/or dilate the lesion.
