Abstract: A sealing pad (100) for sealing a respiratory mask. The mask is configured to create a sealing interface. The sealing interface encircles the nostrils and includes portions crossing the nasal ridge and the concave portions. The pad has a face-contacting side to sealingly engage the face, and a mask contacting side to sealingly engage the mask. The pad (100) includes a portion for crossing the nasal ridge and portions (113) for crossing concave portions on either side of the nose such that the mask contacting side is engageable with the mask to define the portions of the sealing interface crossing the nasal ridge and the concave portions. The pad carries, or has one or more defined apertures (107) for carrying, one or more tube portions for conveying fluid across the sealing interface.

Abstract: A catheter system including a catheter (10) and a stylet (30). The stylet includes an elongate portion (31) and a shaped portion (32). The elongate portion is receivable within the catheter. The elongate portion and the catheter are co-operably configured such that, when the elongate portion is so received, at least a portion of the elongate portion is spaced from the catheter such that the at least portion and the catheter together define at least one elongate void for conveying fluid along the catheter at least one of to or from one or more sites within a patient. The shaped portion is positioned to be within the patient.
