What changed

USPTO issued patent US12594409B2 granting University Hospitals Cleveland Medical Center exclusive rights to a surgical port retention sleeve invention. The device features a two-portion sleeve design where an outer sleeve portion slides distally to mechanically expand radially collapsed flanges into an expanded locked position. The flanges automatically collapse when the outer portion returns to its original position, enabling reversible port fixation.

For medical device manufacturers and healthcare providers, this patent establishes intellectual property protection around a specific surgical port retention mechanism. Manufacturers developing competing surgical access devices should review their designs to avoid potential infringement. Healthcare institutions performing procedures involving surgical ports may benefit from understanding licensed or proprietary access technologies. The patent's 13-claim scope covers both the device structure and the reversible expansion mechanism used for port stabilization.

Abstract

A sleeve for retention of a surgical port is disclosed. The sleeve comprises a first sleeve portion, a second sleeve portion, a plurality of flanges, and a reversible locking mechanism. The second sleeve portion is disposed around the first sleeve portion and is reversibly slidable distally from a first position to a second position along the first sleeve portion. The plurality of flanges is disposed in a radial sequence around the first sleeve portion. The flanges are radially collapsed along the first sleeve portion when the second sleeve portion is in the first position and are radially expanded when the second sleeve portion is in the second position. The first sleeve portion is configured for placement of a surgical port therethrough and to be fixedly secured to the surgical port therealong. Additional sleeves are also disclosed.
