Claim Text:
1. In an imaging catheter, an imaging window, comprising: a first imaging window section, the first imaging window section having a proximal end, a distal end, and a finite length, a constant outer diameter and a constant inner diameter, and a first material having a flexural modulus; and a second imaging window section, the second imaging window section having a proximal end, a distal end, and a finite length, a constant outer diameter and a constant inner diameter, and a second material having a flexural modulus, wherein the flexural modulus of the first material is different than the flexural modulus of the second material, the catheter has a proximal end and a distal end, the first imaging window section is proximal to the second imaging window section, the distal end of the first imaging window section is bonded to the proximal end of the second imaging window section such that the first material at the distal end of the first imaging window section contacts the second material at the proximal end of the second imaging window section, the flexural modulus of the first material is greater than the flexural modulus of the second material, the constant outer diameter of the first imaging window section is equal to the constant outer diameter of the second imaging window section, the constant inner diameter of the first imaging window section is equal to the constant inner diameter of the second imaging window section, and the first and second materials are transparent to ultrasound energy.
