摘要：
A coupling for securing a hollow tip to a catheter shaft generally includes a distal portion and a proximal portion. The distal portion includes a first cylindrical body, an outer surface of which includes at least one circumferential groove and at least one flat region. The proximal portion includes a second cylindrical body, an outer surface of which includes at least one channel. A ramp may also be provided at a distal end of the second cylindrical body. A nominal outer diameter of the first cylindrical body is smaller than a nominal outer diameter of the second cylindrical body. Together, the distal portion and the proximal portion define a tunnel extending through and along a length of the coupling.
