摘要： A steerable delivery apparatus for an implantable medical device comprises a shaft extending distally from the handle, the shaft having a steering-member lumen extending through a length of the shaft, and a steering member extending through the steering-member lumen, the steering member having a proximal end portion and a distal end portion. A pull ring is disposed along a distal end portion of the shaft, the pull ring comprising a proximal segment having a first diameter and a distal segment having a second diameter smaller than the first diameter. The distal end portion of the steering member is fixed to the distal segment of the pull ring, and an adjustment mechanism is further provided in the handle, the mechanism operatively coupled to the proximal end portion of the steering member and configured to adjust tension in the steering member so as to adjust a curvature of the shaft.

摘要： A prosthetic heart valve configured to replace a native heart valve and having a support frame configured to be reshaped into an expanded form in order to receive and/or support an expandable prosthetic heart valve therein. A dual-wireform support frame including an upper and a lower wireform permits expansion of the valve by one or two valve sizes, for example, with a 2-mm gap between each valve size. The lower wireform has a relatively shallow undulation so that it may stretch apart by a small amount and then prevent further expansion of the valve.

摘要： A valved conduit including a bioprosthetic aortic heart valve connected to a tubular conduit graft forming an ascending aorta. The conduit graft may attach to the heart valve in a manner that facilitates a redo operation in which the valve is replaced with another valve. A sewing ring may be pre-attached to the inflow end of the graft, and then the valve connected to a delivery holder advanced into the graft and secured to the sewing ring. Dry bioprosthetic valves coupled with conduit grafts sealed with a bioresorbable medium can be stored with the delivery holder.

摘要： A sizing tool for use in implanting a composite valved conduit having a prosthetic heart valve on a distal end attached to a conduit graft that extends to a proximal end. The tool includes a proximal handle and a distal shaft, a prosthetic heart valve sizer having an axis affixed to a distal end of the shaft, and a conduit graft replica having an axis mounted on the shaft proximal to the heart valve sizer. A method of securing a composite valved conduit includes introducing to an excised ascending aorta the sizing tool, measuring the aortic annulus with the prosthetic heart valve sizer, and determining whether the coronary arteries have sufficient length or whether an additional tubular coronary extension segment is required to add to one or both of the ends of the coronary arteries by extending the coronary arteries toward the conduit graft replica.

摘要： Suture clip deployment devices for applying suture clips to sutures are described. Some embodiments can include a generally tubular main body and a vacuum port located at the distal end, a hollow inner body longitudinally slidable within the main body and extending from the main body at its distal end, and a suture recess located in the generally tubular main body. At least one suture clip configured to frictionally fit on an outer surface of the inner body is deployed during use. Clip deployment can occur after a vacuum source is applied to the device so as to draw the suture into the device. The suture lines can be retrieved through the suture recess, and the device can be actuated so as to deliver the suture clip off the delivery device and onto the suture, locking the suture in place.

摘要： Embodiments of a balloon cover for a balloon catheter are disclosed. The balloon cover can include a first shell member and a second shell member. The first and second shell members are configured to matingly engage with each other to define a lumen that is configured to receive a distal portion of the balloon catheter. The first shell member includes a plurality of first wedges juxtaposed with a plurality of first cavities and the second shell member comprises a plurality of second wedges juxtaposed with a plurality of second cavities. The first wedges are offset with the second wedges such that when the first and second shell members are matingly engaged with each other, the plurality of first wedges are received by the plurality of second cavities and the plurality of second wedges are received by the plurality of first cavities
