Patent number: 9717590Abstract: An ossicular prosthesis is adjustable in length and temporarily and resiliently adjustable in angular orientation. The prosthesis includes a head for contacting a tympanic membrane, and a resilient sleeve is mounted within the head. An elongate shaft extends through the sleeve, and includes a distal end adapted to engage a footplate or stapes. The sleeve forms a resilient joint that allows the shaft to undergo an angular motion relative to the sleeve when subject to a non-axial force, and then subsequently return to its original position after the force is removed. The sleeve may also be longitudinally displaceable within the head of the prosthesis such that the shaft can undergo a damped linear motion. Also as a result of the arrangement of the sleeve, the prosthesis is adjustable to a very short length.Type: GrantFiled: September 25, 2015Date of Patent: August 1, 2017Assignee: ENTEROPTYX, INC.Inventors: Anthony D. Prescott, Patrick Ireland

Patent number: 9320526Abstract: A punctum plug includes a proximal head, a shaft, and a distal body, and an axial bore. The head is defined by a flexible circular flange with a convex upper portion and a concave lower portion. The body defines a frustoconically tapered distal tip and a two wings that extend in an arc and taper in thickness. The wings can extend further radially than the flange of the head. A recessed groove is defined around the shaft extending between the wings and a wall structure connecting the winged portions of the body. The above structure permits one plug or fewer plugs to accommodate a broad patient population.Type: GrantFiled: October 11, 2012Date of Patent: April 26, 2016Assignee: ENTEROPTYXInventors: Richard W.
