Medical dilatation balloons comprise a polymer that has the attribute of memory, and/or is crosslinked to impart memory. Such balloons exhibit a reduced tendency to overinflate at high inflation pressures. Furthermore, such balloons when shrunk radially by the application of heat while restraining axial shrinkage, exhibit customizable linear or non-linear compliance curves and lower crosslinking profile relative to the same balloon when unshrunk. Also disclosed is an expansive element within a tube whose outer diameter is equal to the outer diameter of the tube from which it was made. In addition, disclosed are (a) processes for preparing crosslinkable polymers, (b) joining crosslinked balloons to catheter systems, (c) forming shrunk balloon elements, and (d) forming an expansive element within a tube whose outer diameter is equal to the outer diameter of the tube from which it was made.
A device suitable for heat welding a crosslinked thermoset polymer material to a non-crosslinked thermoplastic material comprising a layer of non-crosslinkable thermoplastic polymer applied to the inner and/or outer surface of a crosslinkable polymer substrate, wherein said device has been exposed to crosslinking energy sufficient to crosslink said crosslinkable polymer substrate while the inner and or/or outer surface or surfaces are maintained in a thermoplastic and heat weldable configuration.
A device suitable for heat welding a crosslinked thermoset polymer material to a non-crosslinked thermoplastic material comprising a non-crosslinkable thermoplastic polymer applied to one or both ends of a crosslinkable polymer substrate, wherein said device has been exposed to crosslinking energy sufficient to crosslink the crosslinkable polymer substrate while the end or ends are maintained in a thermoplastic and heat weldable configuration.
A method for manufacturing a device suitable for heat welding a crosslinked thermoset polymer material to a non-crosslinked thermoplastic material comprising applying a layer of non-crosslinkable thermoplastic polymer to the inner and/or outer surface of a crosslinkable polymer substrate, and exposing said device to crosslinking energy sufficient to crosslink the crosslinkable polymer substrate while the end or ends are maintained in a thermoplastic and heat weldable configuration.
