Abstract
A dacryocystorhinostomy (DCR) tool () includes a perforating shaft () having a distal perforating tip () configured to form a bypass between a lacrimal sac and a nasal cavity through a lateral side of the lacrimal sac, a lacrimal bone, and nasal mucosa. A DCR guide () includes a nasal guide component () configured to be inserted into the nasal cavity and having a distal guide tip (); and a lacrimal guide component () shaped so as to define a guide channel () that orients the DCR guide () with respect to the distal perforating tip () during advancing of the distal perforating tip () through a lacrimal passageway and into the lacrimal sac, until contact of the distal perforating tip () with the distal guide tip () blocks further advancing of the distal perforating tip (). The DCR guide () constrains the distal guide tip () to fall in a path of advancement of the distal perforating tip (). Other embodiments are also described.
