ABSTRACT:
A catheter can be formed from an elongate shaft and a distal tip. The catheter can be formed by flaring a proximal end of the distal tip to form a flared proximal end and positioning the distal tip such that the flared proximal end of the distal tip overlaps a distal end of the outer layer. Heat and pressure are applied to melt and flow together a portion of the outer layer proximate the distal end of the shaft and the overlapped portion of the flared proximal end of the distal tip, thereby forming a joint between the elongate shaft and the distal tip.
