    Abstract: For treatment of a patient who has a lesion in each of left lower limb artery and right lower limb artery, lesions at both sides can be rather easily and completely treated. A catheter is introduced from an artery of an arm of the patient, and an atherectomy catheter is used for a lesion at one side and continuously used for a lesion at the other side without being extracted to the outside of a human body, and thus damage of an excision portion of the atherectomy catheter and an unexpected situation such as no passage through twisted blood vessels are avoided so that a burden on the patient can be reduced, the treatment can be completed within a short time, and cost reduction can be achieved by reducing the number of catheter to be used.

A tube surrounds the optical fiber and is free to move along the axis of the assembly, acting to straighten the tubular and optical fiber members as it moves forward via a sliding member associated with the hand piece. Illumination energy, laser energy, or both may be supplied to the targeted surgical site.

    Abstract: A robotic catheter procedure system includes a bedside system and a workstation. The bedside system includes an actuating mechanism configured to engage and to impart movement to a percutaneous device. The workstation includes a user interface and a control system configured to be operatively coupled to the user interface, the bedside system, and a medical imaging system. The control system is responsive to a first input and to a second input, and the user interface receives the second input from a user. The control system is configured to generate a first control signal to the medical imaging system based on the first input, and the medical imaging system captures at least one image in response to the first control signal. The control system is configured to generate a second control signal to the actuating mechanism based on the second input, and the actuating mechanism causes movement of the percutaneous device in response to the second control signal.

  • Publication number: 20150141960
    Abstract: A catheter loading device includes a guidewire section, a catheter section, and a hinge that connects a proximal end of the guidewire section to a distal end of the catheter section. The guidewire section is rotatable relative to the catheter section about a rotation axis between a first position and a second position. When the guidewire section is in the first position, a longitudinal axis of a guidewire positioned in a channel of the guidewire section is aligned with a longitudinal axis of a lumen of a catheter positioned in a receiver of the catheter section. When the guidewire section is in the second position, the longitudinal axis of the guidewire positioned in the channel is not aligned with the longitudinal axis of the lumen of the catheter positioned in the receiver.

    Abstract: A method of delivering a prosthetic heart valve to a native aortic valve is disclosed. The prosthetic heart valve comprises a radially compressible and expandable metallic stent and a flexible valvular structure. A delivery system comprises a selectively steerable section and a pusher member extending through a central lumen of the steerable section. The prosthetic heart valve is compressed and inserted into a distal end portion of the delivery system. The delivery system and prosthetic heart valve are advanced through a femoral artery and around an aortic arch.

    Abstract: Methods, delivery systems and engaging apparatuses for the placement and treatment of an insufficient or stenotic cardiac valve, such as the mitral valve are disclosed. One such method is based on a two step procedure, where during the first step the engaging apparatus is brought to the valve annulus using a delivery system which permits continued normal blood flow. In some preferred embodiments, this is implemented with a balloon and other preferred embodiments it is implemented using a multi-pronged structure that is collapsible like an umbrella frame. The second step is performed after the engaging apparatus has been integrated into the annular wall by natural processes of tissue healing and remodeling. In the second step the engaging apparatus is tightened leading to tightening of the valve annulus arid correction of existing valvular insufficiency.
