  • Publication number: 20160242903
    Abstract: Apparatus for use with a prosthetic heart valve includes a holder, to which the heart valve is releasably attached, and an elongated handle. The handle can be connected to the holder simply by pushing a distal end of the handle straight into a recess in the holder. After this has been done, the holder preferably releasable latches onto the handle, and the handle can also be rotated about its longitudinal axis to transmit torque to the holder (e.g., a rotatable portion of the holder). Rotation of such a rotatable portion of the holder can be used to deflect portions of the valve radially inward. This operation of a rotatable portion of the holder is preferably one-way only. The handle can be released from the holder at any time, and it can similarly be reconnected to the holder at any time.

  • Publication number: 20160242908
    Abstract: Devices and methods are disclosed for the treatment or repair of regurgitant cardiac valves, such as a mitral valve. An annuloplasty device can be placed in the coronary sinus to reshape the mitral valve and reduce mitral valve regurgitation. A protective device can be placed between the annuloplasty device and an underlying coronary artery to inhibit compression of the underlying coronary artery by the annuloplasty device in the coronary sinus. In addition, the protective device can inhibit compression of the coronary artery from inside the heart, such as from a prosthetic mitral valve that exerts radially outward pressure toward the coronary artery. The annuloplasty device can also create an artificial inner ridge or retaining feature projecting into the native mitral valve region to help secure a prosthetic mitral valve.

  • Publication number: 20160242938
    Abstract: A prosthetic device has a movable body and foot member with an end effector for contacting an external surface. A base body is coupled to a first joint of the foot member. A compliant linking member is disposed between a second joint of the foot member and a first joint of the moveable body. The compliant linking member can be a spring or flexible beam. A passive linking member is coupled between a third joint of the foot member and a third joint of the moveable body. An actuator is disposed between the base body and the second joint of the movable body. The actuator can be a motor with an extension member. The compliant linking member extends during roll-over phase. The actuator acts to assist with the extension of the compliant linking member during roll-over phase to aid with push-off phase in the gait cycle.

  • Publication number: 20160242939
    Abstract: A prosthetic system having a microprocessor-controlled socket evacuation device, and a method of retaining a prosthesis on the residual limb of an amputee using such an evacuation device are described herein. The evacuation device can include an electrically powered vacuum pump. The evacuation device can be operated in a manner that automatically adjusts the socket vacuum level to correspond to a determined activity level of a user. The microprocessor control can also limit operation of the evacuation device to certain determined portions of a user's gait cycle.

  • Publication number: 20160242941
    Abstract: This disclosure contains methods, devices, and systems for object removal from a body, including removal of a stent from a body. Some methods of the present disclosure include inflating a balloon on a catheter, engaging a stent with a socket defined by a surface of the balloon, the surface inwardly sloped toward a lumen of the catheter, and retracting a portion of the stent through the socket and into the lumen. The present disclosure also includes methods for making a catheter, including forming a balloon, inverting a portion of the balloon, and attaching the balloon to a catheter such that a surface of the balloon defines a socket that is inwardly sloped toward a lumen of the catheter.

  • Publication number: 20160242942
    Abstract: A deployment system for a self expanding stent includes a catheter assembly with a tip attached to a distal end segment of an elongate tube. The tip includes a proximal portion molecularly joined to a distal portion, which has a lower durometer hardness than the proximal portion. The proximal portion includes an anchor surface in contact with the distal portion, and oriented perpendicular to a central axis of the elongate tube. The elongate tube may be formed from a thermosetting polyimide, and the overmolded tip may be made from two different colored and different hardnesses of polyether block amide material. The tip is overmolded onto an untreated external surface of the elongate tube.

  • Publication number: 20160242948
    Abstract: A back plate of a waist support includes a plate body and two spring members. The plate body has a valley portion and two positioning holes. The two positioning holes are arranged symmetrically on the right and left sides of the valley portion. Each of the spring members is installed in the positioning hole of the plate body and provides a propping force to a wearer of the waist support. Thereby, the waist support can more effectively distribute the load that is otherwise focused on of the wearer's waist vertebra and in turn provides the wearer with more comfort.
