Process for forming a dimensionally variable tubular member for use in catheterization procedures. The process includes a mechanism for extruding a tubular member. A variable speed puller pulls the tubular member through or from the extrusion means at a selectively variable speed. A variable air or gas pressure supply supplies pressurized air or gas to the extrusion mechanism at a selectively variable rate. The dimensionally varying tubular member may be cut to desired lengths for use as catheter shafts or catheter soft tips. The process may include forming a tubular member having a dimensionally varying first layer and a dimensionally varying second layer, wherein a portion of the first layer at a distal end of the tubular member is removed.
An apparatus for performing the process of manufacturing a catheter having a dimensionally variable tip region for use in catheterization procedures, the apparatus comprising:
A process for forming a dimensionally variable catheter having a tip region including a proximal portion and a distal portion for use in catheterization procedures, the process comprising the steps of:
A process for forming a dimensionally variable tubular member having multiple layers for use with catheterization procedures, the dimensionally variable tubular member having a tip region, the process comprising the steps of:
