  • DEVICES AND METHODS USEABLE FOR TREATMENT OF GLAUCOMA AND OTHER SURGICAL PROCEDURES
    Publication number: 20230157874
    Abstract: A device and method for cutting or ablating tissue in a human or veterinary patient includes an elongate probe having a distal end, a tissue cutting or ablating apparatus located adjacent within the distal end, and a tissue protector extending from the distal end. The protector generally has a first side and a second side and the tissue cutting or ablating apparatus is located adjacent to the first side thereof. The distal end is structured to be advanceable into tissue or otherwise placed and positioned within the patient's body such that tissue adjacent to the first side of the protector is cut away or ablated by the tissue cutting or ablation apparatus while tissue that is adjacent to the second side of the protector is not substantially damaged by the tissue cutting or ablating apparatus.

  • Devices, system and methods for minimally invasive glaucoma surgery
    Patent number: 11266527
    Abstract: A surgical device, system and method for forming opening in the trabecular meshwork of eyes to facilitate drainage of aqueous humor and resultant lowering of intraocular pressure are provided. The device comprises a shaft and a distal member or foot on a distal end of the shaft. The distal member or foot may have a forward tip, a right edge, a left edge and a transversely concave depression, cavity or space between the right and left edges. The distal member is insertable into Schlemm's canal of an eye and thereafter advanceable through Schlemm's canal such that trabecular meshwork tissue will be cut by the right and left edges.
