Publication number: 20230293862Abstract: The present disclosure is directed toward a semi-compliant to non-compliant, conformable balloon useful in medical applications. Conformable balloons of the present disclosure exhibit a low straightening force when in a curved configuration and at inflation pressures greater than 4 atm. Balloons of the present disclosure are constructed of material that can compress along an inner length when the balloon is in a curved configuration. In further embodiments, balloons of the present disclosure can be constructed of material that sufficiently elongates along an outer arc when the balloon is in a curved configuration. As a result, medical balloons, in accordance with the present disclosure, when inflated in a curved configuration, exhibit kink-free configurations and do not cause a significant degree of vessel straightening.Type: ApplicationFiled: May 24, 2023Publication date: September 21, 2023Inventors: Carey V.

Publication number: 20210186555Abstract: Various embodiments provide a device comprising a balloon assembly including a balloon, a film template, and a rigid element. The film template may have a fixed upper distension limit and may include at least one aperture. The rigid element may lay substantially flush with an outer surface of the balloon at a first inflated state of the balloon. The first upper distension limit of the balloon may be greater than the fixed upper distension limit of the film template and the balloon may outwardly protrude through the at least one aperture at a second inflated state. The rigid element may be extended in a radial direction away from the outer surface of the balloon as the balloon outwardly protrudes through the at least one aperture relative to the outer surface of the film template.Type: ApplicationFiled: December 29, 2020Publication date: June 24, 2021Inventors: John E.

Patent number: 10933225Abstract: Novel catheter constructions comprising thin covering or wrapping materials such as polymer films. A catheter provided with a guidewire catheter lumen having a thin covering that is easily punctured by a guidewire at virtually any desired point along the catheter length. The thin covering may be integral with the catheter shaft, or may be a separate component that covers only the portion of the catheter shaft immediately adjacent the outer portion of the guidewire lumen, or may be a thin tubular construct that surrounds the entire catheter shaft. Moreover, polymer film can be used in combination with one or more elements to produce novel catheter constructions.Type: GrantFiled: January 29, 2018Date of Patent: March 2, 2021Assignee: W. L.

Patent number: 10173038Abstract: The invention is directed to delivery medical devices that enable consistent “on-demand” delivery of therapeutic agents to a vessel. The medical device of the current invention comprises retractable sheath comprising neckable elements. The medical device of the current invention comprises an expandable member, a hydrophilic coating comprising at least one therapeutic agent about the expandable member or structural layer and a retractable outer sheath with a selectively permeable microstructure. The design and methods disclosed herein ensures that therapeutic agent delivery occurs essentially only during retraction of the outer sheath, minimizing coating and/or therapeutic agent loss to the bloodstream and providing controlled delivery to the treatment site.Type: GrantFiled: September 4, 2013Date of Patent: January 8, 2019Assignee: W.
