摘要: A tubular prosthetic semilunar or atrioventricular heart valve is formed by cutting flat, flexible leaflets according to a pattern. The valve is constructed by aligning the side edges of adjacent leaflets so that the leaflet inner faces engage each other, and then suturing the leaflets together with successive stitches along a fold line adjacent the side edges. The stitches are placed successively from a proximal in-flow end of each leaflet toward a distal out-flow end. During operation, when the leaflets open and close, the leaflets fold along the fold line. Distal tabs extend beyond the distal end of each leaflet. The successive stitches terminate proximal of the distal tab portion so that no locked stitches are placed along the distal portion of the fold line. The tab portions of adjacent leaflets are folded over each other and sewn together to form commissural attachment tabs. The commissural tabs provide commissural attachment points to accommodate sutures and the like in order to secure the tab to a vessel wall, if a semilunar valve, and papillary muscles and/or chordae tendineae if an atrioventricular valve.

摘要: An improved prosthetic mitral valve is provided having advantageous hemodynamic performance, nonthrombogenicity, and durability. The valve includes a valve body having an inflow annulus and an outflow annulus. Commissural attachment locations are disposed adjacent the outflow annulus. An anterior leaflet and a posterior leaflet of the valve are shaped differently from one another. The inflow annulus preferably is scalloped so as to have a saddle-shaped periphery having a pair of relatively high portions separated by a pair of relatively low portions. The anterior high portion preferably is vertically higher than the posterior high portion.

摘要: In a Viterbi decoder including an add-compare-select (ACS) processor, speed is enhanced without loss of performance by maintaining a dynamic cumulative metric range for computed state metrics. Current state metrics are added to new branch metrics to obtain two computed metrics, and the smaller of the two computed metrics is stored along with previously computed state metrics. The stored state metrics are compared with a selected scale factor, for example one-half maximum scale factor, and all current state metrics are rescaled when the minimum stored metric value exceeds the selected scale factor.

摘要: Disclosed are biocompatible implants that combine a scaffold material for supporting long term repair of a soft tissue with an elongated member such as a suture for aiding in placement of the scaffold during a surgical procedure as well as for immediate mechanical reinforcement of a repair site. The components of an implant are combined such that a longitudinal load placed upon a composite structure can be borne primarily by the elongated member and the scaffold material is isolated from the longitudinal load. Thus, the scaffold material of a composite can be protected from damage due to applied loads and stresses during and following a surgical procedure.
