Publication number: 20150305633Abstract: A catheter includes an elongate shaft including a proximal portion and a distal portion extending from the proximal portion to a distal opening at a distal end of the shaft. The proximal portion defines a proximal guidewire lumen and has a first outer diameter. The distal portion defines a distal guidewire lumen in communication with the proximal guidewire lumen and has a second outer diameter smaller than the first outer diameter. A pressure sensor is coupled to the proximal portion such that the pressure sensor faces the proximal guidewire lumen. When the catheter is tracked to a treatment site within the vasculature, the pressure sensor is disposed proximal the treatment site, the distal opening is disposed distal to the treatment site, and the distal guidewire lumen fills with blood such that the pressure sensor senses a pressure of the blood at the distal end of the shaft.Type: ApplicationFiled: April 23, 2014Publication date: October 29, 2015Applicant: Medtronic Vascular GalwayInventors: Gerry McCaffrey, Fiachra Sweeney, Barry O'Connell, Christopher Murphy, Sean Ward

Publication number: 20150133799Abstract: Embodiments hereof relate to methods and systems for determining a pressure gradient across a lesion of a vessel without requiring the use of a pharmacological hyperemic agent. A measurement system includes at least an injection catheter and a pressure-sensing instrument or guidewire slidingly disposed through the catheter, the pressure-sensing guidewire including at least one pressure sensor configured to obtain a pressure measurement for use in determining the pressure gradient across the lesion. The catheter is configured to deliver or inject a non-pharmacological fluid, such as saline or blood, across the lesion in order to increase a flow rate there-through, thereby simulating hyperemia without the use of a pharmacological hyperemic agent. Once an increased flow rate that simulates hyperemia is achieved, the pressure sensor of the pressure-sensing guidewire may be utilized to measure the pressure gradient across the lesion in order to assess the severity of the lesion.Type: ApplicationFiled: November 14, 2013Publication date: May 14, 2015Applicant: Medtronic Vascular GalwayInventors: Barry O'Connell, Colm Connolly, H.
