摘要： The present invention features a composite catheter comprising an elongate outer member and an elongate inner member positioned within the outer member so that the inner and outer members define an interstitial space. The outer member has a size and other characteristics that facilitate handling and implantation of the composite catheter, while the inner diameter of the inner member has the size and other characteristics suitable for delivery of a drug through a lumen of the inner member. The interstitial space imparts flexibility to the composite catheter by, for example, removing material from the cross-sectional area that would otherwise provide additional stiffness to the catheter, and/or by accommodating movement of the outer member relative to the inner member.

摘要： A dry-state iontophoretic drug delivery device (10, 70, 80) is provided. The device has drug and electrolyte reservoirs (15, 16) which are initially in a non-hydrated condition. A liquid-containing pouch (21, 22) is provided. In certain embodiments the liquid is contained in breakable capsules within the pouch. Water or other liquid can be released from the capsules in the pouch by squeezing or flexing the pouches (21,22). Alternatively, the liquid can be released from the pouches (21,22) using pouch piercing pins (36,37). The liquid released from the pouches (21,22) hydrates the drug and electrolyte reservoirs (15, 16) and activates the device. In another embodiment, the device (20, 20a) has liquid-containing gel layers (31,32) which are initially separated from their respective electrode assemblies (8, 9). Liquid-wicking pathways (27,28) are provided to carry the liquid from the gel layers (31,32) to the drug and electrolyte layers (15, 16).
