    Abstract: A sizer for assessing the geometry of a heart valve annulus. The sizer preferably includes a circular sizing portion for measuring the diameter of the valve annulus. The sizing portion has radial spokes. The spokes are used to compare the symmetry of the commissures to the expected symmetry of a normal heart valve. The sizer preferably has one or more legs attached to the sizing portion for comparing the contour of the line of valve leaflet attachment to the expected contour of a normal heart valve having a diameter substantially equivalent to the measured diameter of the valve annulus.

    Abstract: A concentric mating stent tissue heart valve which is capable of being assembled with a variety of tissue sources is provided. A plurality of prefabricated kits are also provided which enable the valve to be assembled with autogenous tissue in the limited time, i.e., 10 minutes or less, available in the operating room. The inner stent can be configured with a plurality of tissue alignment members extending outward from the inner stent to corresponding holes cut in the tissue. The outer stent can be configured with posts adapted for nesting with corresponding inner stent posts, and integrated with self-adjusting tensioning means, to exert a substantially uniform clamping force on the tissue sufficient to secure the tissue between the stents.

    Abstract: An intraoperative tissue assessment device and method based on optical and mechanical techniques that allows a surgeon to assess certain mechanical properties of tissue samples. The device includes a cavity for housing and securing at least a portion of the tissue sample in communication with a pressurization source to inflate a portion of the tissue forming a dome of tissue having a height axis substantially perpendicular to the tissue sample secured within the cavity. The height of the dome of tissue along the height axis is generally proportional to the strength of the tissue sample. A source of illumination projects collimated light rays in the direction of the dome of tissue illuminating the dome of tissue and creating a Moiré fringe pattern, which may be used to determine the degree of anisotropy of the tissue sample when viewed through a viewing port arranged substantially directly above the dome of tissue.

    Abstract: A surgical instrument for holding a piece of tissue in a configuration of an open circulatory system valve to facilitate surgical attachment of the tissue to the patient's valve annulus. The instrument includes an inner member having a handle portion at one end and an inner tissue holding portion at the opposite end. The inner tissue holding portion includes one or more of inner leaves. An outer member disposed about the inner member includes an outer tissue holding portion having one or more of outer leaves that are complementary and can be engaged with the inner leaves. A collet or other actuator moves the outer leaves radially inward and outward with respect to the inner leaves. The outer leaves are separated from the inner leaves to allow placement of the tissue on the inner leaves. The outer leaves are then moved radially inward to hold the tissue between the leaves in a configuration of one or more leaflets of an open circulatory system valve to facilitate surgical attachment.

    Abstract: The present invention provides a prosthetic heart valve holder specifically configured to hold a prosthetic heart valve comprised of a stent. The heart valve holder assembly has three main components: a handle, a valve capture loop assembly and a valve retainer. The prosthetic heart valve is secured to the valve retainer by a loop of suture as the surgeon sutures or attaches the valve to the annulus of the heart. Thus, the valve holder assembly facilitates attachment of the prosthetic valve to the annulus so that the procedure may be performed in a time and labor efficient manner.

    Abstract: The present invention provides a single-use surgical cutting device for cutting a planar piece of tissue into a predetermined shape. The cutting device comprises a housing having one or more side walls, a top, a base, and a hollow interior portion. A blade retaining member is disposed within the housing between and substantially parallel to the top and base such that the blade retaining member can move vertically between the top and base. A blade defining a predetermined tissue shape is disposed on the bottom surface of the blade retaining member. A pressure mechanism creates potential energy for exerting a downward force on the top surface of the blade retaining member, such that when the blade retaining member is released, the pressure mechanism forces the blade retaining member downward with sufficient force to cut the piece of tissue. An actuator is configured to release the blade retaining member only once without disassembling the housing and resetting the pressure mechanism. Thus, a piece of tissue can be placed beneath the bottom surface of the blade retaining member on or parallel to the base and the actuating mechanism can be actuated to release the downward force on the blade retaining member to cut the piece of tissue into the desired shape, but the cutting device cannot readily be reused by an operator.

    Abstract: A sizer for assessing the geometry of a heart valve annulus including a handle portion for holding the sizer and a sizing portion. The sizing portion is preferably in the shape of an arch having an apex and two legs, each of which has a base adjoining the handle portion. The legs of the arched sizing portion are separated from each other by a predetermined distance that corresponds to the expected separation of commissures of a normal heart valve annulus. The height of the arch (measured from the base of each leg to the apex) corresponds to a predetermined leaflet height that approximates the expected height of a leaflet of a normal heart valve. For aortic valve reconstruction, the instrument is inserted into the opened aortic root following removal of the native valve tissue and is used to assess the distance between the commissures, the leaflet height, and the symmetry of the commissures of the exposed valve annulus.
