Embodiment Construction

[0075] The following detailed description and drawings are intended to describe some, but not necessarily all, examples or embodiments of the invention. Nothing in this detailed description limits the scope of the invention in any way.

[0076] Figures 1 to 2G One embodiment of an implantable substance delivery device and / or spacer 10 of the present invention is shown. The device 10 has an elongated flexible catheter shaft 12 having a proximal portion 12a and a distal portion 12b that can be severed from each other at a spacing marker 15 . The proximal shaft portion 12a and the distal shaft portion 12b may be formed from the same or different materials, and may have the same or different dimensions (eg, diameter, wall thickness, etc.). For example, in some embodiments intended for implantation in a paranasal sinus or other ENT location, the proximal shaft portion 12a may be made of a suitable biocompatible material having sufficient breaking strength ( such as pushability)...

Abstract

Substance delivering spacer devices may comprise expandable reservoirs that are implantable in paranasal sinuses and other cavities, openings and passageways of the body to maintain patency and to provide sustained local delivery of a therapeutic or diagnostic substance. Delivery apparatus including elongate tubular members as well as shapeable distal portions and atraumatic tips are provided. Also provided are sinus penetrator devices and systems for performing ethmoidotomy procedures or for creating other openings in the walls of paranasal sinuses or other anatomical structures.
