Publication number: 20240066542Abstract: An aerosol delivery system has an aerosol generator with a vibrating aperture plate (10) and an actuator (11, 16, 17, 19), a controller (18, 19). The controller in real time monitors (201) the aerosol generator as it is driven for vibration of the aperture plate, and detects (202) a change in an electrical characteristic in response to a transition from a wet state to a dry state of the aperture plate. It automatically modifies (203, 205, 206), during the transition, operation of the aerosol generator in response to the detected change. The modification includes reducing applied power (203). The controller continues (204) to monitor during the transition, including monitoring the aperture plate for presence of residual liquid on the aperture plate first surface.Type: ApplicationFiled: October 26, 2023Publication date: February 29, 2024Applicant: STAMFORD DEVICES LIMITEDInventors: Joseph GREHAN, Noel COYLE, Russell GREANEY, Stephen THORNTON

Publication number: 20080269641Abstract: A method of treating a vascular condition includes inserting at least one locally stiffened guidewire into a vessel, advancing a distal section of the guidewire to a position adjacent a treatment site and providing a stiffening portion of the distal section to a location adjacent the treatment site. The method further includes disposing a delivery catheter over the inserted guidewire, advancing a distal portion of the delivery catheter to the treatment site, the distal portion carrying at least one stent and deploying the stent at the treatment site.Type: ApplicationFiled: April 25, 2007Publication date: October 30, 2008Applicant: Medtronic Vascular, Inc.Inventors: Donagh O'Shaughnessy, Noel Coyle

Patent number: 7273486Abstract: A balloon catheter includes an inflation shaft and an elongated guidewire shaft. A relatively short, distal portion of the guidewire shaft is attached to, or enveloped within, a distal portion of the inflation shaft. A proximal portion of the guidewire shaft is detached from and independent of a proximal portion of the inflation shaft. The detached portion of the guidewire shaft contains perforations at pre-determined points along its length that define removable segments thereof. The removable segments remain attached to the guidewire shaft under normal conditions, but may be torn away from the guidewire shaft to provide access to a guidewire within a guidewire lumen thereof.Type: GrantFiled: April 11, 2003Date of Patent: September 25, 2007Assignee: Medtronic Vascular, Inc.Inventors: Noel Coyle, Patrick Duane

Patent number: 7208001Abstract: A balloon catheter includes a full-length inflation shaft and a guidewire shaft for fast catheter and guidewire exchange. The proximal portions of the inflation shaft and the guidewire shaft are detached from one another. The detached proximal shaft portions transition within a conversion portion of the catheter shaft and become coaxial within a distal portion of the catheter shaft. The proximal portion of the guidewire shaft may contain a continuous, longitudinally extending slot that acts as a guide member or guidewire track. Alternatively, the proximal portion of the guidewire shaft maybe removable from the catheter at a conversion joint via a snap-fit connection. Both embodiments allow for catheter exchange without removing the guidewire from a body lumen, or allow guidewire exchange without removing the catheter from the body lumen.Type: GrantFiled: April 24, 2003Date of Patent: April 24, 2007Assignee: Medtronic Vascular, Inc.Inventors: Noel Coyle, Patrick Duane

Publication number: 20060025721Abstract: An assembly for guiding a catheter includes a catheter, a catheter advancing and retracting apparatus, and a guidewire removal tool. The catheter comprises an elongate shaft having an exterior surface, a proximal end, and a distal end; a first lumen extending through the shaft and sized to receive a guidewire; and a guideway enabling transverse access from the shaft exterior surface to the first lumen. The catheter advancing and retracting apparatus comprises an elongate housing; an opening formed through the housing and adapted to receive the catheter; and a linear slot formed in the housing and adapted to be aligned with a portion of the catheter guideway. The guidewire removal tool comprises a substantially cylindrical main body sized to be receivable by the first lumen and having a chamfered leading edge adapted to raise the guidewire out of the first lumen through the guideway.Type: ApplicationFiled: July 30, 2004Publication date: February 2, 2006Inventors: Niall Duffy, Noel Coyle, David Quinn

Patent number: 6966890Abstract: A convertible balloon catheter for use as either an over-the-wire catheter or a rapid exchange catheter, comprising a flexible outer shaft, flexible inner shaft, angioplasty balloon, and bifurcate hub. The inner shaft is comprised of a relatively elastic, deformable material and forms an inflation lumen. The inner inflation shaft is attached to the outer shaft, and has a cross section that is radially collapsible to increase the size of a full-length guide wire lumen formed between an outer surface of the inner shaft and an inner surface of the outer shaft. Formed in the outer shaft is a hatch, which covers a guide wire port. The hatch has a perforated peripheral edge which allows the hatch to be removed. The balloon is simply constructed with essentially four components, which significantly reduces the labor required for assembly.Type: GrantFiled: August 23, 2002Date of Patent: November 22, 2005Assignee: Medtronic Vascular, Inc.Inventors: Noel Coyle, Niall Duffy

Publication number: 20050070880Abstract: A catheter having a proximal shaft defining a guidewire lumen and an inflation lumen. The inflation lumen is arcuate shaped and reinforced with a tube having an arcuate shaped cross-section or another reinforcing means. The catheter also has a distal shaft, with a greater flexibility than the proximal shaft. The catheter also has a transition section. A proximal end of the transition section communicates with the proximal shaft, and a distal end communicating with the distal shaft. The transition section has a gradually increased flexibility from its proximal end to its distal end. The transition section includes a transition means creating the increased flexibility.Type: ApplicationFiled: March 25, 2004Publication date: March 31, 2005Applicant: Medtronic Vascular, Inc.Inventors: Ashish Varma, Noel Coyle, Richard Gribbons
