A conveyor using a roller belt with rollers arranged to rotate on oblique axes to urge articles toward a side guide. The conveyor includes an oblique-roller belt supported on a carryway for running in a direction of belt travel. Rollers extend above an outer conveying surface of the belt without contact with the carryway. Each roller rotates on an axis oblique to the direction of belt travel and intersects the side guide downstream of the roller's position. A retractable stop is movable to and from a blocking position along the carryway. In the blocking position, the stop blocks the conveyed articles from advancing in the direction of belt travel. The rollers underlying the blocked articles rotate as the belt runs by contact with the articles. The rotating rollers provide a component of force to the blocked articles directed toward the side guide to push the articles against the side guide or other articles as they accumulate under low pressure upstream of the stop. The conveyor may be used to register articles single file against the side guide or to group the articles for palletizing. For palletizing applications, an infeed conveyor feeds articles onto the belt at the side opposite the side guide.

Annuloplasty rings optimally sized to take into account more of the common degenerative valve pathologies. Each ring has a structural ring body with a shape that complies with predicted shapes of degenerative valvular diseases, such as Fibroelastic deficiency (FED), Marfan's or Barlow's. The predicted shapes are obtained through careful echocardiographic and intraoperative measurements, and often differ for different annulus orifice sizes. For instance, in mitral rings the larger rings have larger minor axis and oblique axis dimensions relative to their major axis dimensions, and are more circular as opposed to D-shaped. The rings may also be three-dimensional and the relative heights around the rings may change for different sized rings. A mitral ring may have a higher anterior saddle relative to a posterior saddle, with the relative heights varying across the ring sizes. The ring may have varying flexibility around the ring periphery which also changes for different ring sizes. A bulge on the sewing cuff forms a step on the outflow side for ease of suturing, which may be indicated by a suture line.
