Patent ID: 8512282

Claim:
A medical catheter comprising: a hub assembly; and an elongate shaft extending distally from the hub assembly, the elongate shaft including a proximal section, a midshaft section extending distally from the proximal section with a proximal portion of the midshaft section overlapping a distal portion of the proximal section to form a proximal joint, and a distal section extending distally from the midshaft section and at least partially overlapping the midshaft section to form a distal joint; wherein the proximal section includes a first tubular member; wherein the midshaft section includes a second tubular member and a thermoplastic tubular sleeve extending over the second tubular member, a proximal portion of the second tubular member joined to a distal portion of the first tubular member at the proximal joint; wherein the distal section includes an outer tubular member and an inner tubular member disposed within the outer tubular member, the inner and outer tubular members extending distally from the distal joint, wherein the inner tubular member defines a guidewire lumen extending distally from a guidewire port located at the distal joint, the guidewire port providing access to the guidewire lumen from exterior of the elongate shaft; and wherein the thermoplastic tubular sleeve is bonded to at least one of the inner tubular member and the outer tubular member of the distal section at the distal joint and extends proximally to the proximal joint to a location proximal of a proximal end of the second tubular member such that a proximal portion of the thermoplastic tubular sleeve surrounds a portion of the first tubular member.
