Publication number: 20230302256Abstract: A steerable introducer deflectable via a handle assembly is described. The handle assembly includes slide members disposed within a slide chassis and coupled to deflection wires to deflect the introducer, and a slide block divider for constraining slide members. The slide block divider and the slide chassis combine to form a slide compartment in which each of the first slide member and the second slide member is slidably disposed. The slide block divider can prevent the deflection wires from crossing each other within the handle assembly, and constrain each of the slide members during translation within the slide compartment to inhibit motion transverse to a longitudinal direction of the slide compartment. The slide block divider can provide an improved handling of the steerable introducer.Type: ApplicationFiled: March 16, 2023Publication date: September 28, 2023Applicant: St. Jude Medical, Cardiology Division, Inc.Inventors: Wade Welter, Andrew Oliverius, Troy Tegg, Neil Hawkinson, Tobias Cajamarca
