Abstract:
An improved holder, system and method for implanting a tissue-type prosthetic heart mitral valve that constricts the commissure posts of the valve and allows the user to detach the handle of the holder prior to withdrawing the holder itself. The ability to remove the handle allows a surgeon greater access to suturing the prosthetic valve to the mitral annulus. The holder may include two relatively movable plates, one of which attaches to the valve sewing on the inflow end of the valve ring and the other which attaches via sutures to the valve commissures on the outflow end. Separation of the plates places the sutures in tension and constricts the commissures. An adjusting member or adapter is interposed between the handle and holder to enable separation of the two plates and removal of the handle. The adjusting member or adapter may be packaged with the valve and holder combination, or may be sold as a separate unit, possibly with the handle, so that prior art holders can be retrofit.

Abstract:
A design and method of implantation is disclosed for a flexible annuloplasty system for repairing a valve in a patients heart. The annuloplasty system includes an elongate, flexible band with a needle attached to one end of the band and a fit adjuster attached to the other end of the band. The band is made of silicone and includes a plurality of fibers that are configured to prevent axial elongation of the band. In addition, the plurality of fibers ensure that a suture will catch on the fibers and prevent the suture from tearing out of the band.

Abstract:
Substantially continuous fluid delivery in a variable-speed peristaltic pump is achieved by operating the pump at maximum speed through most of the deadband regardless of the delivery rate. Safety means are disclosed to monitor the correct operation of the speed control.

Abstract:
An annulus sizer measures the size of a valve annulus during annuloplasty surgery. The annulus sizer includes a sizing portion for measuring the valve annulus and a coupling portion for attaching to a handle. The coupling portion is disposed on a proximal surface of the sizing portion. The sizing portion has a thickness on the order of about 0. 1 inch. This relatively small thickness of the sizer facilitates minimally invasive annuloplasty surgery. For example, the sizer may be inserted through a relatively small intercostal incision. In addition, the relatively thin sizing portion minimizes optical distortion. The coupling portion may be disposed on the sizing portion at a location which is offset from the center of the sizer, thereby defining an enlarged viewing area. The coupling portion may have threading to engage with threading of the handle to ensure secure attachment.

Abstract:
A multi-purpose surgical implement handle has proximal and distal ends. A gripping section is located toward the proximal end, and an attachment section is located toward the distal end. An adjusting section is interposed between the gripping section and the attachment section. The adjusting section may be bent by a human user at virtually any discrete location along the section. The adjusting section may include an increased-adjustability portion which is easier to bend than other portions of the adjusting section.
