Publication number: 20240032893Abstract: Endovascular apparatus for determining the condition of a vessel in a body comprises an elongate waveguide element such as a wire and an activation unit comprising a source of ultrasonic energy to activate the waveguide element, hence transmitting ultrasonic energy to an active distal section of the waveguide element. A signal acquisition system acquires feedback signals from the apparatus for interpretation of vessel condition. The signal acquisition system comprises at least one acoustic sensor for acquiring acoustic feedback signals generated by, the apparatus when the waveguide element is activated. Data sets may be generated from acoustic and non-acoustic feedback signals and combinations of, or comparisons between, those data sets can characterise the condition of the vessel, including any lesion such as a blockage in the vessel.Type: ApplicationFiled: December 17, 2021Publication date: February 1, 2024Applicant: VERSONO MEDICAL LIMITEDInventors: Finbar DOLAN, Dion GUILFOYLE, Ben KINSELLA, Ivan MOONEY, Hugh O'DONOGHUE, Mary O'DONOGHUE, Jim SMEDLEY

Publication number: 20220125452Abstract: An endovascular apparatus for crossing through an obstruction in a blood vessel comprises an elongate endovascular wire and a coupling. The coupling when in use transmits ultrasonic energy along the wire from an ultrasonic energy source to an active tip at a distal end of the wire. The coupling is arranged to couple the source to the wire at any of a plurality of discrete operational positions along the length of the wire for said transmission of ultrasonic energy to the active tip.Type: ApplicationFiled: November 6, 2019Publication date: April 28, 2022Applicant: Versono Medical LimitedInventors: Finbar Dolan, Hugh O'Donoghue

Patent number: 8227016Abstract: The present invention provides a method of applying a drug-polymer coating on a stent. A stent framework is dipped into a first polymeric solution including a first polymer, a first therapeutic agent, and a first solvent. The polymeric solution is dried and the first polymer is cured to form a thin drug-polymer layer on the stent framework. The steps of dipping the stent framework into the first polymeric solution, drying the first polymeric solution, and curing the first polymer are repeated until a target drug-polymer coating thickness is disposed on the stent framework. A drug-polymer coated stent including a stent framework and a laminated drug-polymer coated stent, a system for treating a vascular condition, and a method of treating a vascular condition are also disclosed.Type: GrantFiled: May 18, 2010Date of Patent: July 24, 2012Assignee: Medtronic Vascular, Inc.Inventors: Ronan Thornton, Finbar Dolan
