摘要：
A device receptacle of a catheter resides in a sidewall thereof, which includes a proximal section, a central section extending distally from the proximal section, and a distal section extending distally from the central section. A length of the central section is approximately 30% of an overall length of the sidewall； the proximal and distal sections have approximately the same stiffness； and a stiffness of the central section, formed from a polymer material without any structural reinforcement or any other member embedded therein, is significantly less than that of the proximal and distal sections. When an operator causes the receptacle sidewall to buckle, a distal opening of a chamber of the receptacle becomes aligned with an implanted device so that the operator can bring the implanted device into the chamber to retrieve the device from the implant site.
