Publication number: 20230006635Abstract: An integrated circuit (IC) resonator module for an IC package includes an acoustic resonator having a surface and a Bragg reflector adhered to the surface of the acoustic resonator. The Bragg reflector includes low impedance layers formed of a first material with a first acoustic impedance and a high impedance layer formed of a second material with a second acoustic impedance. The second acoustic impedance is greater than the first acoustic impedance. The Bragg reflector further includes a Bragg grating layer formed of randomly or periodically spaced patches of the second material separated by vias filled with the first material.Type: ApplicationFiled: June 30, 2021Publication date: January 5, 2023Inventors: Huiyao Chen, Ting-Ta Yen, Ricky A.

Publication number: 20200397556Abstract: A vascular filter device (1) has a support frame (2) and filter elements (4). The filter elements (4) extend from the support frame towards filter element ends forming an on-axis apex (5) at which they are interconnected by a holder (6). The filter elements (4) are biased such that if unconnected the filter element ends are located between the support frame and said central axis when the vascular filter device is unconstrained. The filter element unconnected positions are provided by the filter element shapes and the angles at which they extend from the support frame, and in one example this is achieved by laser cutting tubing and heat setting the material.Type: ApplicationFiled: September 2, 2020Publication date: December 24, 2020Applicant: Novate Medical LimitedInventors: Paul Gilson, Steven Horan, Karl Keating, Damien Ryan, Jacqueline O'Gorman, Paul Bateman, Martin Keegan, Declan Broderick

Patent number: 8123778Abstract: An embolic protection system comprises an embolic protection filter 1 having a collapsed delivery configuration and an expanded deployed configuration. The filter 1 is housed in the collapsed configuration in a reception space of a delivery catheter 20. The delivery catheter 20 containing the filter 1 is housed in a sealed sterile pouch 35. The filter 1 may be coated with a non-thrombogenic coating and an adhesion preventer 9 such as a silicon gel is used to substantially prevent adhesion of adjacent folds of the filter 1 when the filter is in the collapsed configuration in the delivery catheter 20.Type: GrantFiled: October 28, 2008Date of Patent: February 28, 2012Assignee: Salviac LimitedInventors: Eamon Brady, Gary Fahey, Brendan Casey, Ann Marie Cannon, David Vale, Martin Keegan

Publication number: 20110054516Abstract: An embolic protection filter for deployment in a vasculature, the filter having an inlet end and an outlet end, the inlet end having one or more inlet openings sized to allow blood and embolic material enter the filter, and the outlet end of the filter having a plurality of outlet openings sized to allow through passage of blood but to retain undesired embolic material within the filter. The filter is movable between a collapsed configuration for movement through a vasculature, and an outwardly extended configuration for deployment in a vasculature. The filter at least in the collapsed configuration was a guidewire lumen defined at least partially therethrough for passing the filter over a guidewire. The guidewire lumen is defined by a lumen-defining member which is spaced proximally of the distal end of the filter.Type: ApplicationFiled: November 8, 2010Publication date: March 3, 2011Applicant: SALVIAC LIMITEDInventors: Martin Keegan, Eamon Brady, Brendan Casey, David Vale, John Neilan, Morgan Tierney

Patent number: 7766952Abstract: A delivery and deployment system for a self-expanding stent comprises a proximal handle having a rotatable thumbscrew and a sliding component which is attached to a distal stent restraining sheath. A rigid open coil spring is provided for converting rotation of the thumbscrew into translation of the sliding component). The spring is attached to the thumbscrew. The sliding component is located between adjacent coils of the spring. Rotation of the thumbscrew twists the spring and slowly slides the sliding component and hence the distal sheath in the proximal direction to uncover the stent, removing the constraint on the stent which is accurately deployed at the site of interest. The handle has a guide elongate channel which constrains the sliding component so that it cannot move in a rotational direction.Type: GrantFiled: June 6, 2006Date of Patent: August 3, 2010Assignee: Salviac LimitedInventors: Steven Horan, Eamon Brady, Martin Keegan

Publication number: 20080039863Abstract: A delivery catheter 1 for rapid exchange delivery of a stent 7 through a vasculature over a guidewire 10, and for rapid exchange deployment of the stent 7 at a desired site in the vasculature. The catheter 1 comprises a hypotube 2, a distal sheath 4 which defines an internal reception space for the stent 7, and a push wire 3. The catheter body 2 is fixedly attached to the sheath 4 by means of a junction piece 9. At the distal end of the wire 3, the catheter 1 comprises a tubular inner core 5 and a coiled spring 6 which acts as an abutment means for engagement with the stent 7 in the reception space upon retraction of the sheath 4 to facilitate deployment of the stent 7. The guidewire 10 passes proximally from the inner core 5, through the junction piece 9, and out of the junction piece 9 through a proximal guidewire opening 11.Type: ApplicationFiled: November 22, 2006Publication date: February 14, 2008Inventors: Martin Keegan, Shane Molloy, Siora Coll, Steven Horan, Brendan Casey
