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.

An atrial shunt regulation device, a braid tool and a braid method thereof. The left disk (1) and the right disk (2) of the atrial shunt regulation device are connected via the intermediate portion (3) as a single piece, and the left disk (1), the intermediate portion (3) and the right disk (2) are braided by a single braid wire (10). The ends of the braid wires are secured by one nut in the single-braid method, which reduces the number and size of the nuts and easily forms a cortical layer. The braid tool for braiding an atrial shunt regulation device comprises a cylinder braid body mold (20), the cylindrical braid body mold (20) includes positioning pins (21) that are evenly connected to an outer wall of the braid body mold. The braid method of the atrial shunt regulation device comprises braiding, thermoforming, braiding a binding-off wire, securing ends of wires by a nut, and thermoforming again. The braid method is easy, the process is easy, and the device can be made manually in small batches to reduce costs.

A composite structural component including a braided material embedded in a resin matrix, the braided material with multiple braided components formed of continuous tows and connected by one or more intersections are described. Each of the multiple braided components is formed by sets of tows. Each set of tows includes a respective plurality of tows, which are substantially adjacent and parallel to each other at an angle relative to the longitudinal axis of the braided material. Each set of tows is further composed of multiple subsets of tows. The subsets of tows separate at the intersections and combine with different subsets of tows in adjacent components of the multiple braided components.

A protective textile sleeve and method of construction thereof is provided. The sleeve includes a circumferentially continuous wall extending lengthwise along a longitudinal axis between opposite ends. The wall has a first section formed from a non-heat-shrinkable, non-elastic yarn and a second section formed from one of a heat-shrinkable or elastic yarn. The first section extends lengthwise between the opposite ends and spans (X) degrees about the circumference of the wall between opposite lengthwise extending edges while in an unshrunken or stretch. The second section extends lengthwise between the opposite ends and spans (360-X) degrees about the circumference of the wall. The heat-shrikable or elastic yarn of the second section extends continuously as an uninterupted yarn between the opposite edges of the first section.

In one embodiment according to the present invention, a stent is described having a generally cylindrical body formed from a single woven nitinol wire. The distal and proximal ends of the stent include a plurality of loops, some of which include marker members used for visualizing the position of the stent. In another embodiment, the previously described stent includes an inner flow diverting layer.
