摘要： A method and device for treating a Chronic Total Occlusion provides a controllable stiffness catheter with a shaft having a stiffness sheath and an access lumen. The device has a stiffness device in a stiff state below a given temperature and in a soft state above the temperature, a temperature-changing device in thermal contact with the stiffness device, the temperature-changing device changing a temperature of the stiffness device below and above the temperature, and a power controller electrically connected to the stiffness device and selectively supplying power to the temperature-changing device to change a stiffness of the stiffness device between the stiff and soft states. A guidewire is moved to a treatment site and the catheter moves along the guidewire up to CTO in its soft state. The catheter stiffens without straightening and, in the stiff state, the catheter or the guidewire is projecting through the CTO.

摘要： A method for delivering RF energy to living tissue includes the steps of extending a guidewire to a tissue treatment site in a body. A controllable stiffness catheter is provided with a stiffness device and a temperature-changing device. The stiffness device is in a stiff state below a given temperature and in a soft state above the given temperature. While supplying power to the temperature-changing device, the catheter is threaded along the guidewire up to the treatment site in the flexible state of the catheter. Power is removed from the temperature-changing device to change stiffness of the stiffness device to the stiff state without straightening the catheter. The RF energy supply device is physically contacted with the treatment site and RF energy is delivered to the treatment site from the RF energy supply device.

摘要： An end effector assembly for a forceps includes jaws, a cutting assembly, and at least one cam assembly. At least one jaw is moveable relative to the other about a pivot between open and closed positions for grasping tissue. At least one jaw includes a control trough that extends therealong. The pivot has first and second pivot bosses defining a pivot hole therebetween. The cutting assembly includes a blade and blade control portion, and defines a longitudinal axis through the blade and the control portion. The control portion slidably translates through the pivot hole defined between the pivot bosses to allow selective advancement thereof through the trough. The blade is disposed distally of the pivot and extends farther from the axis than an outer surface of the control portion. The cam assembly is coupled to the moveable jaw and is actuatable to move the moveable jaw between the positions.
