1. A lacrimal implant insertable into a lacrimal canaliculus, comprising:
- an implant body, including first and second portions, the implant body extending from a proximal end of the first portion to a distal end of the second portion;
the proximal end of the first portion defining a longitudinal proximal axis and the distal end of the second portion defining a longitudinal distal axis;
the implant body configured such that, when implanted in the lacrimal canaliculus, an angled intersection exists between the proximal axis and the distal axis for biasing at least a portion of the implant body against at least a portion of the lacrimal canaliculus located at or more distal to a canalicular curvature; and
wherein the second portion of the implant body includes a longitudinal length having a magnitude less than four times a longitudinal length of the first portion of the implant body.

20. A lacrimal implant for insertion into a lacrimal canaliculus, comprising:
-
an implant body non-linearly extending from a proximal end portion positionable within a vertical section of the lacrimal canaliculus to a distal end portion positionable within a horizontal section of the lacrimal canaliculus and having an intermediate portion therebetween; the intermediate portion partially extending in a first direction toward the proximal end portion and partially extending in a second direction toward the distal end portion such that, when implanted in the lacrimal canaliculus, the implant body directionally biases laterally against at least a portion of the lacrimal canaliculus located at or more distal to a canalicular curvature; and wherein the implant body inhibits fluid flow into and through the lacrimal canaliculus. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
