摘要： The present invention relates to open irrigated catheter ablation systems and methods used in connection with open irrigated catheter systems. The systems and related methods can control irrigation fluid flow to obtain temperature responses indicative of temperatures associated with an ablation procedure. Embodiments of the present invention provide irrigated catheter ablation systems having controlled irrigation fluid flow that can be directed at target areas where coagulation is more likely to occur to help minimize blood coagulation and associated problems. The irrigated fluid flow may be regulated in connection with an established or predetermined temperature threshold to improve or better optimize cooling and ablation properties of the system. In embodiments, irrigation flow may be either delayed or intermitted.

摘要： A delivery device for an implantable medical device having at least one retention member at an end thereof includes a shaft extending in a longitudinal direction, an elongated sheath surrounding a longitudinal portion of the shaft, a compartment defined inside of the sheath and adapted to receive the medical device in an assembled condition, a retainer positioned at one end of the compartment, and at least one acceptance in the retainer adapted to receive the retention member of the medical device in the assembled condition. The sheath is slidable relative to the shaft in the longitudinal direction to uncover and deploy the medical device. The retainer may be rotatable relative to the shaft to reduce torsional forces in the medical device during delivery and deployment. The retainer may have at least one recess facing the compartment for receiving a strut at an end of a stent of the medical device.

摘要： A delivery device for a collapsible heart valve includes an operating handle, including a frame defining a movement space therein, a carriage assembly moveable within the movement space, and a first resheathing lock having a locked position and an unlocked position. The delivery device further includes a catheter assembly, including a first shaft around which a valve-receiving compartment is defined, the first shaft being fixedly connected to one of the frame or the carriage assembly, and a distal sheath operatively connected to the carriage assembly. The distal sheath is moveable between a closed condition adapted to maintain the valve in the compartment and an open condition adapted to fully deploy the valve. With the resheathing lock in the locked position, the distal sheath is unable to move to the open condition to fully deploy the valve.

摘要： A delivery device (100) includes a support member (128), a distal sheath (130), an outer shaft (120) and a strengthening member (140). The support member is adapted to hold a prosthetic heart valve. The distal sheath is slidable relative to the support member between a first position in which the distal sheath is adapted to maintain the prosthetic heart valve in a collapsed condition, and a second position in which the distal sheath is adapted to expose the prosthetic heart valve. The outer shaft is connected to the distal sheath and has a curved portion (134). The straightening member is slidable on the outer shaft between a proximal position in which the straightening member does not cover the curved portion of the outer shaft, and a distal position in which the straightening member covers and substantially straightens at least a portion of the curved portion of the outer shaft.
