Suture of varying cross-section and methods of manufacture and use
The present invention includes, in one embodiment, a method of forming a suture having various cross-sectional shapes, the method including the steps of braiding the suture such that the suture has a first cross-sectional shape along a length; holding a first end of the suture and holding the suture at a second position at a location in between the first end and a second end such that a first portion of the suture is defined between the first end and the second position; manipulating the first end relative to the second position to alter the first portion of the suture into an altered cross-sectional shape different from the first cross-sectional shape; and releasing the first end and the second position, wherein the step of manipulating is performed such that, upon release, the first portion maintains its manipulated shape.
Composite fibers and method of producing fibers
Composite fibers created by a process including vertically texturizing and impregnating resin into the fibers at controlled viscosity results in stronger fibers in which virtually no microbubbles are trapped resulting in improved tensile strength for use in reinforcing concrete and other materials.

Methods of manufacture of catheter with helical drive shaft
Drive shafts having helical blades and methods of making are disclosed. In one method a helical auger blade is formed by twisting or sculpting a heated polymer tube which has been placed over a cylindrical drive shaft. In another method a drive shaft is placed within a helical winding and heat is applied to melt polymer which has been coated over one or both of the drive shaft and helical winding.

Method and preform for forming a device comprising a shape memory polymer
There is provided herein a method of manufacturing a device comprising at least a first fibre using a draw apparatus, the method comprising: providing a first preform comprising a shape memory polymer to the draw apparatus; heating a first portion of the first preform; and drawing, using the draw apparatus, the heated first portion in order to form the first fibre.
BRAIDED DRAINAGE CATHETER
A drainage catheter may include a polymeric tubular member and a braided reinforcement that is disposed about the polymeric tubular member. The braided reinforcement may include a repeating braid pattern that extends over a first portion of a length of the drainage catheter and a modified braid pattern that extends over a second portion of the length of the drainage catheter, the modified braid pattern providing a region without any braid filaments. The drainage catheter may include a drainage hole that extends through the polymeric tubular member within the region without any braid filaments.

Mould for Furnace/Steam Bending of Plastic or Rubber Tubes and a Method of Producing It
The invention relates to a mould for furnace/steam bending of plastic or rubber tubes, which comprises a shaping labyrinth (3). The shaping labyrinth (3) comprises at least two adjacent parts (I, II), each of which is provided at the end intended to connect to the adjoining part with a connecting flange (6) for joining the adjacent parts (I, II) of the labyrinth (3). The invention also relates to a method of producing a mould for furnace/steam bending of plastic or rubber tubes, in which is formed a shaping labyrinth (3), whose shape is subsequently adjusted according to the control master jig of the tube to be shaped. Afteradjustement of the shape of the labyrinth (3), the adjusted labyrinth (3) is scanned by a 3D scanner and subsequently a digital 3D model of the individual parts (I, II) of the labyrinth (3) is created for the 3D printer, whereupon at least one part (I, II) of the labyrinth (3) is printed on the 3D printer and the individual parts (I, II) of the labyrinth (3) are joined, the surface is blurred and, optionally, the adjacent parts (I, II) of the labyrinth (3) are additionally joined also undetachably, apart from being joined detachably.
