Abstract: A medical implant insertion system comprising a medical implant cartridge including a medical implant, a head having a first end and a second end, and a pin slidably extending through the head, the pin having a first end and a second end, the first end of the pin being located adjacent the first end of the head and being removably attached to the medical implant; the second end of the pin being positioned adjacent the second end of the head; and a medical implant insertion instrument including a handle for removable attachment to the second end of the head of the medical implant cartridge, collet structure for attachment to the second end of the pin of the medical implant cartridge when the handle is attached to the second end of the head of the medical implant cartridge, and actuator structure;for causing the medical implant to detach from the pin of the medical implant cartridge.

Abstract: A punctal occluder for blocking the flow of lacrimal fluid from the surface of an eye through a lacrimal punctum. The punctal occluder includes a shank having a distal end for insertion into the lacrimal punctum; and a distal flange attached to the distal end of the shank for insertion into the lacrimal punctum; the distal flange including a wing portion having a first position extending substantially along the shank for allowing easy insertion of the distal flange into the lacrimal punctum, and having a second position extending substantially outward from the shank for hindering unintentional removal of the distal flange from the lacrimal punctum.
