Leadless delivery catheter with conductive pathway

A catheter, implantable leadless pacing devices, systems, and methods utilizing catheters and implantable leadless pacing devices are disclosed. An example catheter system may include a holding structure extending distally from a tubular member. An implantable device, such as a leadless pacing device, may be located within a cavity of the holding structure. The holding structure may include one ormore electrical ports adjacent the proximal end of the holding structure and adjacent or proximal of the proximal end of the implantable device. The electrical ports may provide a conductive pathwayextending through the distal structure to allow electrical signals to pass through the distal structure to and/or from the implantable device. 公开了导管和可植入无引线起搏装置、系统以及利用导管和可植入无引线起搏装置的方法。示例性导管系统可以包括从管状构件向远侧延伸的保持结构。可植入装置，比如无引线起搏装置，可以位于保持结构的腔体内。保持结构可以包括邻近保持结构的近侧端部并且邻近或靠近可植入装置的近侧端部的一个或多个电端口。电端口可以提供延伸穿过远侧结构的导电通路，以允许通过远侧结构向和/或从可植入装置传递电信号。
