DETACHMENT TOOL FOR DECOUPLING A SHAPE SENSOR FROM AN IMPLANTABLE DEVICE

摘要

A deployment device (30) for interfacing an implantable device (20) with an anatomical structure (10) employs a sheath (31), a shape sensor (32) and a detachment tool (33). The sheath (31) includes a deployment section (31a) for deploying the implantable device (20) to an interface position relative to the anatomical structure (10), and an implantable section (31b) for coupling the deployment section (31a) to the implantable device (20). The shape sensor (32) guides the implantable device (20) to the interface position and includes a deployment segment (32a) extending partially or completely through the deployment section (31a), and an implantable segment (32b) attached to the deployment segment (32a) and extending partially or completely through the implantable section (31b) of the sheath (31). The detachment tool (33) is disposed relative to the implantable section (3 lb) and in operation, the detachment tool (33) may be used to detach a portion or an entirety of the implantable segment (32b) from the deployment segment (32a).
