Title: Ultrasonically flared medical-device components and methods thereof
Patent number: US11331114B2 | Application: US16/346,694 | Publication: US20200069324A1
Assignee: C. R. BARD, INC. (original and current assignee listed; an assignment dated 2022-06-13 identifies inventor Pandia, Deepa as assignor)
Inventor (listed): Deepa Deepa
Dates (as stated, assumptions per source): Priority date 2016-11-28; filing date 2017-11-14; publication 2020-03-05; granted/publication date 2022-05-17; adjusted expiration 2038-07-19; status Active.
Purpose (per supplied text): Addresses adverse effects of ultrasound on medical-device components in ultrasound-based atherectomy. The excerpt states an insufficiently attached tip member to a core wire is expected to cause unwanted flaring from the ultrasound used; a need exists to control such adverse effects, including unwanted flaring.
Plain-language scope (from supplied definitions/excerpt): A catheter comprising a core wire, a sonic connector at its proximal terminus, and a tip member at its distal terminus. The core wire may be at least partially within a lumen of an elongate body. The sonic connector couples to an ultrasound-producing mechanism. The tip member is welded to the core wire at one or more weld locations, and flares from the core wire at one or more weld-free locations; the flare's manner is "characteristic of ultrasonic activation of the tip member." The medical-device component is defined as a flared tip member of an atherectomy catheter for ultrasound-based atherectomy of intravascular lesions. Classifications include A61B17/320068, A61B17/22012, A61B2017/22014, and A61M25/0074. Figures cited: FIG. 1 and FIGS. 2B–2F. The system may include a console, ultrasound generator, transducer, and foot switch.
What the excerpt does not establish: It does not set forth full claims, the complete specification, exact weld/flare dimensions, materials, method steps, or prosecution history. It provides no findings on validity, infringement, prior-art scope, or ownership beyond the single listed assignment entry.

PTAB challenges
AIA trial proceedings at the USPTO Patent Trial and Appeal Board — IPR, PGR, and CBM. Petitioners, judge panels, claim-level invalidation outcomes from Final Written Decisions, and Federal Circuit appeals. The single most important defensive datapoint after litigation history.
Assignment history
Inventors, original assignee, and the chain of ownership recorded with the USPTO — including the correspondent attorney who recorded each assignment, since shell-LLC chains often share one repeat-player attorney even when the entity names look unrelated. Surfaces NPE / patent-troll patterns: shell-entity transfers, known asserters in the chain, repeat correspondent fingerprints, pre-litigation assignments, and bankruptcy fire-sales.
Prior art
Earlier patents, publications, and products that may anticipate or render the claims unpatentable.
Obviousness
Combinations of prior art that suggest the claimed invention would have been obvious under 35 U.S.C. § 103.
Extensions
Patent term adjustments, term extensions, continuations, divisionals, family members, and expiration dates.
Derivative works
Defensive disclosure: derivative variations of each claim designed to render future incremental improvements obvious or non-novel.
