Publication number: 20220361762Abstract: The heart valve assessment systems described herein advantageously provide indicators of a heart valve condition, such as a pressure gradient or a valve regurgitation index. The heart valve assessment systems can provide indicators of a heart valve condition during a heart procedure. A pressure gradient indicates a severity or measurement of the narrowing (or stenosis) of a valve by the increase in pressure behind it. A valve regurgitation index indicates a leakiness measurement of a valve.Type: ApplicationFiled: May 13, 2020Publication date: November 17, 2022Inventors: Sébastien Lalancette, Thomas Goodhart, Maxime Deland, Claude Belleville

Publication number: 20220192520Abstract: A pressure guidewire is provided that includes an outer tube, a connector tube positioned radially inward of the outer tube, a pressure sensor assembly, and/or a distal tip at the distal end of the outer tube. A core wire may be positioned distal to the connector tube. The core wire may have a reduced diameter portion such as a tapered portion. The pressure sensor assembly may include a pressure sensor positioned distal of the connector tube, for example radially between a coil portion of the outer tube and the core wire. The pressure sensor assembly may also include one or more pressure wires leads extending from the pressure sensor and through the connector tube lumen.Type: ApplicationFiled: May 13, 2020Publication date: June 23, 2022Inventors: Sébastien Lalancette, Maxime Picard Deland, Claude Belleville

Publication number: 20220175256Abstract: A pressure guidewire is provided that has a proximal end and a distal end. The pressure guidewire has a proximal section a sensor housing section, and an intermediate section. The proximal section extends from the proximal end of the pressure guidewire to a distal end of the proximal section. The sensor housing section is disposed adjacent to the distal end of the pressure guidewire. The intermediate section disposed between the proximal section and the sensor housing section. The intermediate section has a proximal end separate from the proximal section. The proximal end can be coupled to the distal end of the proximal section. The pressure guidewire has a tubular body positioned within the intermediate section.Type: ApplicationFiled: April 21, 2020Publication date: June 9, 2022Inventors: Sebastien Lalancette, Claude Belleville, Philippe Lafleur, Jean-Sebastien Mercier

Patent number: 9405075Abstract: The present document describes an interface connector handle for connecting a first optical fiber to a second optical fiber. The first optical fiber is substantially centered within a proximal portion of a guidewire tubing. The second optical fiber is routed through and extending from an optical interface cable. The interface connector handle comprises a biasing assembly for urging one of the first optical fiber and the second optical fiber toward the other one of the first optical fiber and the second optical fiber resulting in a contact therebetween.Type: GrantFiled: February 26, 2014Date of Patent: August 2, 2016Assignee: OPSENS INC.Inventors: Claude Belleville, Sébastien Lalancette, Alain Proulx

Patent number: 9405078Abstract: There is described a method for terminating an optical fiber within a proximal portion of a guidewire tubing. The guidewire tubing has an outside diameter and comprises a lumen. The method comprises centering the optical fiber relative to the outside diameter of the proximal portion of the guidewire tubing. The optical fiber and the inside of the lumen define an average gap there between. The average gap around the optical fiber is between 1 ?m and 100 ?m for allowing a substantial displacement of the optical fiber inside the lumen during the centering.Type: GrantFiled: November 27, 2014Date of Patent: August 2, 2016Assignee: OPSENS INC.Inventors: Claude Belleville, Sébastien Lalancette, Alain Proulx

Patent number: 8752435Abstract: There is described a miniature fiber optic pressure sensor design where sensitivity around specific biased pressure is optimized. In an embodiment, the pressure sensor is a Fabry-Perot (FP) sensor which comprises a substrate; and a diaphragm mounted on the substrate. The diaphragm has a center and comprises: a first layer comprising a first material; and a second layer comprising a second material. The second layer forms a dot or a ring. The dot or ring is mounted on the first layer and is centered about the center of the diaphragm. The second material comprises internal pre-stresses to cause the center of the diaphragm (in the case of a dot) or the peripheral area about the center of the diaphragm (in the case of a ring) to camber away from the substrate upon relaxing the internal pre-stresses.Type: GrantFiled: March 8, 2012Date of Patent: June 17, 2014Inventors: Claude Belleville, Sebastien Lalancette, Nicolas Lessard
