Abstract: An arthroscopic port introduction system includes an elongate hollow introducing needle and an elongate stylet sized and adapted to be disposed within the elongate hollow introducing needle together forming a single tissue-penetrating tip. The system also includes an elongate hollow enlarging shaft adapted to be disposed over the elongate hollow introducing needle. An operative tissue-penetrating length of the elongate hollow introducing needle is exposed beyond a distal end of the elongate hollow enlarging shaft. The elongate hollow introducing needle can be removed in a proximal direction from the elongate hollow enlarging shaft. An arthroscopic port sheath is disposed over the elongate hollow enlarging shaft and an operative tissue-penetrating length of the elongate hollow enlarging shaft is exposed beyond a distal end of the arthroscopic port sheath. The elongate hollow enlarging shaft can be removed in a proximal direction from the arthroscopic port sheath.

Abstract: Disclosed is a method of forming at least a portion of a mask (4) that is structured to engage at least a portion of the face of a patient (52). The method can be generally stated as including employing at least a portion of a data set (74) that is stored on a machine-readable storage medium (72) and that is representative of the shape of at least a portion of the face in generating a configuration for an cushion element (24) of the mask. The cushion element is structured to extend from a support (20) of the mask and to have an engagement end (50) bopposite the support that corresponds with the shape of the at least portion of the face. The method can be generally stated as further including subjecting a workpiece (78) to a formation operation to cause at least a portion of the workpiece to be formed into the cushion element having the engagement end.

Abstract: A slotted drain having a first channeled half having a first engaging structure and a second channeled half having a second engaging structure mating within the first engaging structure is disclosed. The first channeled half can define a cantilever snap-fit recess and the second channeled half can comprise a cantilever snap-fit protrusion. A slot is formed when the first and second channeled halves are joined. The slot is adapted to receive a liquid variant and the slotted drain is adapted to receive the liquid from the slot into the first and second channeled halves. The slotted drain may optionally include a concrete pass-through port, a rebar clip, bedding feet and/or securement ribs. A method of assembling a slotted drain is also disclosed.

Abstract: A two-part grate assembly for a channeled drain trough. The grate assembly has a grate frame that receives a removable grate section. The grate frame has lugs with vertical projections extending therefrom that define securing recesses that assist in aligning and securing the grate frame atop a drain trough. Additionally, the present invention is directed to the use of an alignment bar that prevents the grate section from sliding out of operating position within the grate frame by restricting lateral movement of the grate section. Further, the present invention is directed to a method of providing a grate assembly for a channeled drain trough having a grate frame that is adapted to receive a removable grate section.
