Publication number: 20220062599Abstract: A balloon catheter includes an outer tube that has an inner surface and an inflation lumen and an inner tube that is disposed within the inflation lumen. The balloon catheter also includes a collar that has a proximal end coupled to a distal end of the outer tube, and a distal end. The collar is coupled to an edge of the distal end or the inner surface of the outer tube. The balloon catheter further includes a luminal space, which is defined by a space between the outer surface of the inner tube and the collar, and a balloon. The balloon has a proximal end coupled to the collar and a distal end coupled to the inner tube.Type: ApplicationFiled: December 21, 2019Publication date: March 3, 2022Applicant: Crannmed LimitedInventor: Liam Farrissey

Publication number: 20220047843Abstract: A method for coating an inner lumen surface of a tube with a coating solution comprises the steps of moving a coating solution through a tube via a withdrawal system and depositing the coating solution onto an inner lumen surface of the tube. The thickness of the coating solution is deposited onto the inner lumen surface of the tube is between 1 ?m and 25 ?m. The method further comprises applying a pressure to the tube using a pressure source when the coating solution is within the tube to manipulate a surface tension between the coating solution and the inner lumen surface of the tube.Type: ApplicationFiled: December 21, 2019Publication date: February 17, 2022Applicant: Crannmed LimitedInventors: Liam Farrissey, Brendan Duffy, Sankalp Agarwal

Patent number: 10398469Abstract: An expandable introducer sheath for use in interventional procedures. The expandable introducer sheath can be inserted into a treatment vessel in a first unexpanded configuration. The expandable introducer sheath can expand in diameter during insertion of a device through its main lumen and can then re-collapse down to its unexpanded diameter. The device comprises an inner heat-set folded layer and an outer elastomeric layer. The outer elastomeric layer provides a barrier between the inner folded layer and a vessel wall during unfolding of the inner folded layer to minimize the risk of vessel trauma.Type: GrantFiled: July 15, 2016Date of Patent: September 3, 2019Assignee: Creganna Unlimited CompanyInventors: James Coyle, Bernard McDermott, Brendan Marrinan, Liam Farrissey, Adam Szczepanski

Patent number: 10327811Abstract: In a transseptal crossing needle device for inserting an outer sheath through a septum, an inner dilator sheath is received within the outer sheath and a needle having a curved end portion adjacent a tip of a tip portion of the needle is provided, the needle being received in the inner dilator sheath. The needle tip portion comprises an angled transverse end surface terminating at said tip and slanting away from an inner concave curved wall of said inner sheath curved by the needle curved end portion, the needle tip being spaced not only away from said inner concave curved wall of said inner sheath but also away from an inner convex curved wall of said inner sheath opposite said concave wall to reduce or eliminate skiving of material from the concave and convex inner walls of the inner sheath.Type: GrantFiled: October 24, 2014Date of Patent: June 25, 2019Assignee: Creganna Unlimited CompanyInventors: William Cannon, Brendan Marrinan, Liam Farrissey, Bernard McDermott, Richard Gribbons

Patent number: 9283015Abstract: The present invention generally is directed toward a spinal fixation system whereby a coupling element allows the physician to selectively lock or unlock either the connection between the coupling element and a fastener, such as to allow for repositioning of the coupling element, or the connection between the coupling element and an elongate rod. The locking or unlocking of these connections may be made independently and as desired by the physician.Type: GrantFiled: December 4, 2013Date of Patent: March 15, 2016Assignee: Globus Medical, Inc.Inventors: Francisca Tan-Malecki, John V.

Patent number: 8623025Abstract: The invention relates to a systems, devices and methods of delivering and deploying a stent into a curvilinear cavity within a vertebral body or other bony or body structure. In some instances, a system can include an elongate shaft for delivering a self-expanding, cement-directing stent. The elongate shaft can include at least one of an inner shaft, an outer shaft, a tubular sheath, a flexible guidewire, and an internal polymer extrusion. A rotational handle can be used to control movement of the elongate shaft. The rotational handle can incorporate one or more pins in slots associated with each of the components (e.g., inner shaft, outer shaft, and tubular sheath), such that upon rotation of the handle, the pins are forced to move in the direction of their respective slots.Type: GrantFiled: January 15, 2010Date of Patent: January 7, 2014Assignee: Gmedelaware 2 LLCInventors: Francisca Tan-Malecki, John V.
