An elongate medical device shaft may comprise an elongate body and an annular electrode disposed on the elongate body. The annular electrode may define a longitudinal axis and have an outer diameter. The outer diameter may be greater at an axial center of the electrode than at an axial end of the electrode. Additionally or alternatively, the elongate body may comprise three longitudinal sections having three wall thicknesses. The middle wall thickness may be less than the proximal and distal wall thicknesses and the distal wall thickness may be less than the proximal wall thickness. Additionally or alternatively, the shaft may comprise an inner cylindrical structure and an outer tube. The outer tube may comprise a first radial layer and a second radial layer that is radially-outward of the first radial layer, the first radial layer, second radial layer, and inner structure having different stiffnesses.

A protective shipper comprises a cover and a base that are held together by a latching member. The base is configurable to retain and protect semiconductor wafers or film frames with wafers within a storage pocket. The base comprises latching member and a support wall that defines a storage pocket. The cover encloses the storage pocket. One or both of the cover may receive recesses for gripability. The cover may receive one or more latching apertures configured to minimize unintended unlatching. The shipper of the present invention may be manufactured in a mold capable of producing film frame or wafer containing configurations of the shipper by using an interchangeable mold insert.

Protective shipper

A cassette, particularly suitable for storing film frames, in a preferred embodiment utilizes an integral shell portion with a plurality of shelves to support a plurality of axially aligned horizontally stacked film frames. A door, preferably vacuum-formed, covers the open front of the shell to enclose the film frames therein. The cassette may have a robotic top and collapsible handles. In a preferred embodiment the handles are U-shaped and slideably engaged with a pair of brackets integral with the sidewall. In another embodiment the handles pivot about an axis parallel to the top of the cassette and attach by a pair of split prongs insertable into a pair of receiving holes. A pair of film frame retention members are pivotally and rotatably attached at the sides of the shell inside the front opening. The restraints are pivotable between an open position where they are aligned with the sidewalls and pointing toward the open front to a film frame retention position where they are rotated to face inwardly in an approximately radial direction. The film frame retention members may be actuated by handles positioned on the top of the enclosure. Alternatively, the retention members may be automatically actuated by a helical cam mechanism with a engagement portion extending below the cassette to contact a surface upon which the cassette is placed. The members may be biased and spring loaded such that they remain in the retention position and/or the open position when so placed.

Horizontal cassette

A tray for semiconductors having a tray portion, a rail portion, and an intermediate portion. The tray portion has a plurality of chip recesses formed therein. The rail portion extends substantially around the tray portion. The intermediate portion interconnects the tray portion and the rail portion and is oriented at an angle of more than 115&#xb0; with respect to the rail portion.

Tray for semiconductors

An interlockable film frame carrier has central and peripheral portions for securely storing a film frame, the film frame supporting a film, a semiconductor wafer disposed on the film. The central portion has structure for supporting the semiconductor wafer and for allowing access to a lower surface of the stored film frame. The peripheral portion of the film frame carrier includes structure for supporting a peripheral portion of the film frame and matable stacking members. When the film frame is stored, two film frame carriers are interlocked by mating the stacking members. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. 37 CFR &#xa7;1.72 (b).

300MM single stackable film frame carrier

A modular carrier system uses a shell portion to house semiconductor wafer disks or similar inventory. The modular carrier system uses an external frame with accessories attached to the frame so that multiple configurations of accessories are possible with each shell portion and the accessories can be recycled when the shell portion is disposed.
