1. A catheter body for an intravascular medical catheter, comprising:
- a first body portion comprising a first polymeric material, and proximal and distal ends and a first lumen extending from the proximal end to the distal end, at least portions of the first body portion being flexible and suitable for introduction into a blood passageway located within a patient;
a second body portion comprising a second polymeric material, and proximal and distal ends and a second lumen extending from the proximal end to the distal end, at least portions of the second body portion being flexible and suitable for introduction into the blood passageway located within the patient;
a multiple locking mechanism, comprising;
a first threaded connector at the proximal end of the first body portion;
a second threaded connector at the distal end of the second body portion, wherein the first and second threaded connectors cooperate to connect the proximal end of the first body portion to the distal end of the second body portion;
a first interlocking element at the proximal end of the first body portion; and
a second interlocking element at the distal end of the second body portion, wherein the first and second interlocking elements interlock when the first and second threaded connectors connect the first and second body portions together.

Abstract
A catheter having a multiple locking mechanism for connecting a proximal portion of the catheter shaft to a distal portion of the catheter shaft is provided. Also provided is a method for connecting a catheter shaft employing the multiple locking mechanism of the invention. The multiple locking mechanism permits a proximal shaft to be joined with a distal end portions, while simultaneously ensuring integrity of the connection between the proximal shaft and the distal end portion.

13. A method for assembling an at least partially flexible intravascular medical catheter suitable for introduction within a blood passageway of a patient, comprising:
-
providing a catheter, comprising; a first body portion comprising a first polymeric material, and proximal and distal ends and a first lumen extending from the proximal end to the distal end, at least portions of the first body portion being flexible and suitable for introduction into a blood passageway located within a patient; a second body portion comprising a second polymeric material, and proximal and distal ends and a second lumen extending from the proximal end to the distal end, at least portions of the second body portion being flexible and suitable for introduction into the blood passageway located within the patient; a multiple locking mechanism, comprising; a first threaded connector disposed at the proximal end of the first body portion; a second threaded connector at the distal end of the second body portion, wherein the first and second threaded connectors cooperate to connect the proximal end of the first body portion to the distal end of the second body portion; a first interlocking element disposed at the proximal end of the first body portion; and a second interlocking element disposed at the distal end of the second body portion, wherein the first and second interlocking elements interlock when the first and second threaded connectors connect the first and second body portions together; connecting the first body portion with the second body portion by rotatably engaging the first and second threaded connectors; interlocking the first and second interlocking elements; and placing the first and second lumens in fluid communication. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
