Patent number: 10918525Abstract: A tympanostomy tube delivery device comprises a shaft assembly, a pressure equalization tube, and a sensor. The shaft assembly comprises a cannula and a pusher operable to translate relative to the cannula. The pressure equalization tube is positioned within the shaft assembly. The pusher is operable to drive the pressure equalization tube out of the shaft assembly. The sensor is operable to detect a physical parameter associated with engagement between the distal end of the shaft assembly and a tympanic membrane. A controller may activate a feedback device to inform an operator that the distal end of the shaft assembly has achieved suitable apposition with the tympanic membrane, based on information from the sensor.Type: GrantFiled: February 28, 2019Date of Patent: February 16, 2021Assignee: TUSKER MEDICAL, INC.Inventors: Bernard H. Andreas, Rohit Girotra, Jeffrey A. Walker, T. Daniel Gross, Mathew D. Clopp, Mahyar Z. Kermani, Scott J. Baron

Patent number: 10653446Abstract: A tympanostomy tube delivery device comprises a body, a cannula extending distally from the body, and a cylindraceous member disposed within the cannula. The cylindraceous member comprises a tubular portion and a plurality of leaves positioned at the distal end of the tubular portion. The leaves are movable between a collapsed position and an expanded position. The cylindraceous member is slidable relative to the cannula to selectively expose the leaves relative to the open distal end of the cannula. A first leaf of the plurality of leaves has a sharp distal point configured to pierce a tympanic membrane and a longitudinally extending sharp edge. The cylindraceous member may be used to create and dilate a myringotomy incision in a tympanic membrane. The tympanostomy tube delivery device may then be used to deploy a tympanostomy tube through the myringotomy incision.Type: GrantFiled: June 19, 2017Date of Patent: May 19, 2020Assignee: TUSKER MEDICAL, INC.Inventors: Bernard H.

Patent number: 9271707Abstract: An apparatus for delivering a closure element can include a splittable carrier tube and a splitter to split the tube. The carrier tube can have an outer surface retaining a closure element in a tubular configuration and can be split into radially-expandable flaps. A closure element can have a shape-memory body having a relaxed configuration with a planar-annular body defining a lumen with tines directed inwardly from the body. The clip can be held in a retaining configuration having a substantially asymmetrically-elongated tubular shape with a trapezoidal longitudinal cross-sectional profile and a proximal end having the tines being longitudinally directed with a first tine being more distally oriented compared to a substantially opposite second tine being more proximal, and retracting to a deploying configuration having a tubular shape with a rectangular longitudinal cross-sectional profile with the first tine being even with the second tine when being delivered.Type: GrantFiled: March 8, 2013Date of Patent: March 1, 2016Assignee: INTEGRATED VASCULAR SYSTEMS, INC.Inventors: Thomas J.
