Patent number: 9421346Abstract: An introducer adapted to facilitate positioning of a catheter, such as an intrauterine catheter, is provided. The introducer includes an elongate member having an outer wall defining a longitudinal axis and a longitudinal lumen for reception of a catheter, e.g., an intrauterine catheter. The outer wall includes first and second longitudinal edges defining a longitudinal slot in communication with the longitudinal lumen. The outer wall has a cross-section orthogonal to the longitudinal axis and defining a thickness at an opposed location generally opposing the longitudinal slot greater than a thickness at edge locations adjacent the first and second longitudinal edges, to thereby permit the first and second longitudinal edges to be displaced relative to each other to increase a dimension of the longitudinal slot to facilitate one of removal or insertion of the catheter via the longitudinal slot and relative to the longitudinal lumen.Type: GrantFiled: April 16, 2009Date of Patent: August 23, 2016Assignee: Covidien LPInventors: Mark J. Callahan, Linda D'Elia, Mary Jo Griffin
