An improved holder and method for implanting a tissue-type prosthetic mitral heart valve that prevents suture looping and may also constrict the commissure posts of the valve. An upstanding or shaft member axially positioned on the holder causes the lengths of attachment sutures to extend axially beyond the commissure post tips to create a tent and prevent looping of any of an array of pre-implanted sutures around the tips during deployment of the valve. The shaft member may be axially movable such that it can be initially retracted and then actuated just prior to valve deployment. The shaft member may have notches on its distal tip for capturing the attachment sutures, which are crossed over along the valve axis to ensure engagement by the notches. The attachment sutures may be strands or filaments, or may be wider bands of flexible biocompatible material. If bands are used, they desirably cover the commissure post tips to further help prevent suture looping thereover. The flexible lengths of material extend directly between commissures of the valve, or may extending radially inward from each commissure to a central upstanding member.

A vehicle front body structure includes a side-member front area 11F inclined outwardly in the width direction of a vehicle as directing ahead of the vehicle, a strength control mechanism C provided in the side-member front area 11F, a sub-side member 20 extending from the vicinity of a continuous base of the side-member front area 11F toward the front of the vehicle, substantially straight to an extension of a side-member rear area 11R. The front end of the sub-side member 20 is connected with the rear face of a bumper reinforcement 12. The sub-side member 20 is provided with a deformation-mode control mechanism D that allows the sub-side member 20 to be deformed inwardly in the width direction of the vehicle due to a collision input and interferes with a power unit P, forming an impact load transfer mechanism B.

Improved aperturing of a web can be obtained by providing pins with an extended tapered section that is substantially convex in shape. When the tapered section is longer than the penetration depth of the pins into the receiving recesses of a female roll, frictional forces in the nip between layers are reduced. Pins with extended tapered sections can be used in devices for producing apertured composite web assemblies comprising sections of absorbent matter attached to a nonwoven web or other carrier layer.

An alkaline cell having a flat casing, preferably of cuboid shape. The cell can have an anode comprising zinc and a cathode comprising nickel oxyhydroxide. The casing can have a relatively small overall thickness, typically between about 5 and 10 mm, but may be larger. Cell contents can be supplied through an open end in the casing and an end cap assembly inserted therein to seal the cell. The end cap assembly includes a vent mechanism, preferably a grooved vent, which can activate, when gas pressure within the cell reaches a threshold level typically between about 250 and 800 psig (1724×10³ and 5515×10³ pascal gage). The cell can have a supplemental vent mechanism such as a laser welded region on the surface of the casing which may activate at higher pressure levels.

The present invention sets out a label containing an RFID transponder having a uniform printable surface. The present invention presents a face sheet having an increased rigidity and/or thickness which does not readily conform to the profile of an RFID transponder contained beneath the face sheet. This results in a label having a more readily printable surface, and also presents a label having higher security as a result of the masking of the profile of the contained RFID responder.
