Estimating the term…
Balloon catheter covers are elastic fabric structures of interconnected yarns, the structure having a high degree of stretch and recovery in the circumferential direction with little change in dimension in the longitudinal direction during multiple pressurization cycles over full range of inflation and deflation of the balloon catheter. The covers have longitudinal yarns positioned at about zero degrees to the balloon axis and reversibly-stretchable, circumferential yarns positioned at a high angle Ø to the axis. A method for making the balloon catheter covers allowing nearly orthogonal placement of circumferential and longitudinal yarns involves triaxial braiding a minimum number of elastomeric braid yarns with multiple axial yarns to provide maximum convergence angle (approaching 90 degrees).
A balloon catheter cover comprising a tubular elastic fabric structure of interconnected circumferential and longitudinal yarns, the structure having a high degree of stretch and recovery in the circumferential direction.
A process for making a tubular structure having a longitudinal dimension and a circumferential dimension to be used as a balloon catheter cover in which multiple longitudinal yarns are placed from a fixed source along the longitudinal dimension over a core so as to not intertwine with themselves and multiple circumferential yarns from moving sources are intertwined in the circumferential dimension with the longitudinal yarns and themselves.
A braiding process for making balloon catheter covers comprising triaxially braiding 2, 4 or 6 elastomeric braiding yarns with multiple axial yarns.
A triaxial braiding process wherein the number of braiding yarn is less than half of the number of axial yarns.
A method of making a balloon catheter cover in which the balloon catheter cover is formed directly over a balloon catheter.
A method of making a balloon catheter cover in which the balloon catheter cover is formed over a removable mandrel and the cover is subsequently placed over a catheter balloon.
