摘要： A sphincterotome is disclosed including an elongate shaft having a lumen extending through at least a portion of the elongate shaft. The lumen includes a proximal segment and a distal segment. A cutting element extends within the lumen through the proximal segment of the lumen and extends exterior of the elongate shaft along the distal segment of the lumen. A stiffening member is positioned within the distal segment of the lumen.

摘要： A drainage catheter delivery system for positioning a drainage catheter or stent within a body cavity, such as a ureter. The delivery system includes a guide catheter, a push catheter, a drainage catheter (or stent) and a retention device. The guide catheter includes an outer diameter sized to slidably receive the push catheter and the drainage catheter. In this regard, the push catheter is placed over the guide catheter proximal the drainage catheter. The retention device selectively connects the push catheter to the drainage catheter. During use, the delivery system is pre-assembled as described above. The assembled delivery system is directed within a body cavity such that a distal end of the guide catheter is in close proximity to the desired drainage catheter position. The push catheter is axially slid along the guide catheter to move the drainage catheter away from a proximal end of the guide catheter. Conversely, the drainage catheter is retracted, or moved toward the proximal end of the guide catheter by retraction of the push catheter. Retraction of the push catheter retracts the drainage catheter via the retention device. Once properly positioned, the drainage catheter is released from the retention device by retracting the guide catheter from the drainage catheter.

摘要： Stent delivery systems and methods for making and using stent delivery systems are disclosed. An example stent delivery system may include a guide catheter. A push catheter may be slidably disposed over the guide catheter. A stent may be slidably disposed over the guide catheter and disposed adjacent to a distal end of the push catheter. An attachment mechanism may be coupled to the push catheter that is configured to engage the stent. The attachment mechanism may include a base and at least one cantilever extending from the base.
