Abstract:
1. A medical device, comprising: an elongate catheter shaft including a proximal region and a distal region, the distal region including an axle region, the axle region being longitudinally positioned between a first portion of the distal region and a second portion of the distal region, the first portion having a first diameter, the second portion having a second diameter, and the axle region having a third diameter, wherein the third diameter is less than the first diameter and the second diameter, the elongate catheter shaft defining an inflation lumen therethrough, wherein the axle region defines a fluid opening in fluid communication with the inflation lumen; and a rotatable assembly mounted about the axle region of the elongate catheter shaft, wherein the rotatable assembly is rotatable relative to the elongate catheter shaft, the rotatable assembly including a barrel, an expandable balloon, a stent, and a secondary guidewire housing, wherein the balloon is disposed about the barrel, the balloon including a body region defining a stent receiving region, a proximal waist bonded adjacent to a proximal end of the barrel, and a distal waist bonded adjacent to a distal end of the barrel, the balloon being expandable between a reduced state and an expanded state, wherein the barrel defines at least one fluid port in fluid communication with an interior of the balloon, the at least one fluid port being in fluid communication with the inflation lumen via the fluid opening of the axle region, wherein the secondary guidewire housing defines a secondary guidewire lumen and is engaged to the elongate catheter shaft proximal of the balloon.
