Patent number: 12402876Abstract: A releasable elongated assembly includes a release member having a length and an opening that extends along the length. The releasable elongated assembly includes a first elongated element having a first coupling member disposed in the opening and a second elongated element having a second coupling member disposed in the opening opposite the first coupling member along the length. The first and second elongated elements are interlaced with each other in the opening at a location between the first coupling member and the second coupling member such that the first and second elongated elements are attached to each other. The release member is moveable from a first position where the first and second coupling members are captured in the opening to a second position where the first and second coupling members are released from the opening so as to detach the first and second elongated elements from each other.Type: GrantFiled: May 14, 2024Date of Patent: September 2, 2025Assignee: Teleflex Life Sciences LLCInventors: Greg A. Walters, Michael Dotsey
