Technical Examples

A balloon catheter for treatment of a patient's lacrimal system is applied transnasally without the use of a guide wire or a curve retention member. The catheter uses a stainless steel hypotube of sufficient stiffness and column strength to be pushed from the patent's nasal cavity through an opening-formed through the lateral nasal wall and lacrimal fossa, into the lacrimal sac. The catheter has an inflatable member mounted about a rigid bent distal segment. The opening is first formed by pushing small holes through the medial sac, lacrimal fossa, and lateral nasal wall with an instrument and coalescing the holes. The catheter is then introduced into the nasal cavity and pushed laterally through the opening by manipulating its proximal end. Pressurized fluid is then applied to the catheter to inflate the inflatable member and dilate the opening.
