  • Patent number: 10238528
    Abstract: A fluid collection system for collecting fluids leaked from a surgical incision is provided. The fluid collection system broadly includes a baseplate having an adhesive backing that couples the baseplate to a patient's skin and includes a wafer having a centrally positioned opening. The opening receives a first end of a surgical drain tube. A wafer connector is disposed around the opening and detachably couples to a fluid remover connector on a fluid remover The leaked fluid remover defines a septum space and a septum is housed within the septum space. The septum has an orifice that receives a second end of the surgical drain tube. The septum is capable of moving about radially, axially and/or pivotally to alleviate side load tension on the septum caused by displacement of the surgical drain tube.

  • Patent number: 10219943
    Abstract: A method for treating glaucoma with an implantable glaucoma device includes inserting a hollow elongated needle into the eye between the cornea and iris and into the anterior chamber of the eye to form a needle tract in the eye, introducing a distal end of a guidewire through the needle and into the anterior chamber, introducing a snare through a corneal incision into the anterior chamber. The snare has a sheath and a hook or loop inside the sheath and extendible therefrom. The method includes capturing a segment of the guidewire proximate the distal end of the guidewire with the snare within the anterior chamber, removing the needle from over the guidewire outside of the eye, coupling a glaucoma drainage device to a proximal end of the guidewire that extends outside of the eye, and pulling on the captured guidewire segment with the snare to pull the glaucoma drainage device into the needle tract and into the anterior chamber of the eye until the glaucoma device is located in an implanted position in the eye.
