ATRAUMATIC STENT AND METHOD AND APPARATUS FOR MAKING THE SAME
A method of braiding a stent includes braiding a number of elongate filaments around a mandrel using tensioned braiding carriers without spooling the filaments to the tensioned braiding carriers to form a braided stent having atraumatic ends.
ELECTROSPUN PTFE COATED STENT AND METHOD OF USE
A stent or other prosthesis may be formed by coating a single continuous wire scaffold with a polymer coating. The polymer coating may consist of layers of electrospun polytetrafluoroethylene (PTFE). Electrospun PTFE of certain porosities may permit endothelial cell growth within the prosthesis.

MOULDED PLATES, FASTENED WITH CLAMPS FOR OSTEOSYNTHESIS AND ORTHOSIS, AND MANUFACTURING PROCESS
The invention is a solution for osteosynthesis made with molded metal sheets joined vertically and horizontally, fitted to the shape and dimensions of the fractured bone to keep it immobile and united. For the orthosis, it depicts metal sheets joined with horizontal and vertical movements, molded to the form and dimensions of vertebrae and joints to keep them separated. The sheet metals have wavy shapes, channels and undulations that give consistency and structural strength to bending, tension, shear and bends for joints. It also describes the process for the osteosynthesis with metal sheets and 3D printing, where the surgeon wraps the osteosynthesis or molded orthosis around the bone, vertebrae or joint, fastening it with clamps that tighten and lock with a surgical instrument, without screws. The sheet metals have viewpoint holes to see through during surgery and subsequent control with Roentgen. The clamps are in channels, which have micro-points on the side contacting the bone.
Self-expanding devices and methods therefor
Described here are delivery devices for delivering one or more implants to the body, and methods of using. The delivery devices may deliver implants to a variety of locations within the body, for a number of different uses. In some variations, the delivery devices have a cannula with one or more curved sections. In some variations, a pusher may be used to release one or more implants from the cannula. In some variations, one or more of the released implants may be a self-expanding device. Methods of delivering implants to one or more sinus cavities are also described here.

Stents for prosthetic heart valves and methods of making same
A single piece stent construction having a plurality of commissure posts, each of which extends upwardly from a solid ring along a bend line and generally along a central longitudinal axis of the stent.

Prosthesis with branched portion
Examples of prostheses are provided having an internal branch. A tubular graft body of the prosthesis defines a main lumen extending between an inflow end and an outflow end of the graft body. A stent structure is coupled along the graft body. A trough is at least partially defined by a trough wall extending into the main lumen from a sidewall of the graft body. A side branch defines a branch lumen and extends from the trough within the main lumen towards one of the inflow or outflow ends of the graft body. A branch lumen facing surface of the trough wall is a continuous surface with an outer surface of the sidewall of the graft body. A boundary of the trough may be configured to provide a smooth transition surface between the trough and the sidewall.
