Patent number: 11712544Abstract: Guide extension catheters and related methods are disclosed. A guide extension catheter can comprise an elongate tube member and a lumenless push member. The push member can be eccentrically coupled to the tube member for slidably positioning the tube member within and partially beyond a distal end of a guide catheter. At least a proximal end portion of the push member can include a cross-section defined by an arcuate first surface and an opposing second surface. The first surface can engage an inner wall surface of the guide catheter along an arc length, and the second surface can be spaced furthest from the first surface at its center point. The first surface can have the same or substantially the same radius of curvature as the guide catheter's inner wall surface, and the second surface can be flat or substantially flat. This configuration of the push member can provide an advantageous blend of stiffness and flexibility, as well as space conservation through the guide catheter.Type: GrantFiled: July 10, 2020Date of Patent: August 1, 2023Assignee: Teleflex Life Sciences LimitedInventors: Joshua Brenizer, Dean Peterson

Patent number: 11660425Abstract: This patent document discloses perfusion catheters and related methods for treating complications related to CTO interventions or dilating a vessel occlusion while maintaining a passage through the treated vessel segment. A perfusion catheter can include an inflatable balloon coiled in a helical manner around a central axis into a series of windings. An inner surface of the series of windings, when inflated, can define a passage through the inflatable balloon. A catheter can also include an elongate shaft extending from a proximal portion to a distal portion, having an inner surface that defines a lumen for providing inflation fluid to, or withdrawing inflation fluid from, a distal end of the inflatable balloon. A catheter can further include a guidewire support tube including a lumen, separate from the lumen from the elongate shaft and the passage through the inflatable balloon, for receiving a guidewire.Type: GrantFiled: April 30, 2021Date of Patent: May 30, 2023Assignee: Teleflex Life Sciences LimitedInventors: Dean Peterson, Loic Van Horne, Danny Jester

Publication number: 20230028504Abstract: This patent document discloses perfusion catheters and related methods for treating blood vessel lesions and abnormalities. A perfusion catheter can include an inflatable balloon, an elongate shaft operably attached to the balloon, and an optional containment structure surrounding at least a portion of the balloon. The balloon can be inflated until its outer surface contacts a wall of a blood vessel. When inflated, the balloon's inner surface defines a passage for blood to flow. The balloon can be configured to release one or more substances formulated to treat a tissue at or near the wall of a blood vessel. In an example, the balloon can include a bioactive layer, which comprises the one or more substances, overlaying an optional base layer. In an example, the balloon can include multiple filars, at least one of which is configured to elute the one or more substances through a perforation or hole in the filar.Type: ApplicationFiled: September 30, 2022Publication date: January 26, 2023Applicant: Teleflex Life Sciences LimitedInventors: John Bridgeman, Peter Jacobs, Dean Peterson, Joshua Brenizer, Loic Van Horne

Publication number: 20220358337Abstract: RFID tag ICs may be configured with privacy modes. When a tag IC is in a privacy mode, it will not respond to commands unless a previous command includes correct verification information or specifies a recycling indicator of the tag IC. If the previous command includes correct verification information, then the tag IC will respond to one or more subsequent commands as normal, for example by responding with one or more identifiers. If the previous command does not include correct verification information but specifies a recycling indicator and the privacy mode is recycling-enabled, the tag IC may respond to one or more subsequent commands with recycling information. The recycling information identifies whether or how an item associated with the RFID IC can be recycled or disposed but does not otherwise identify the RFID IC or item. Otherwise, the tag IC may remain silent.Type: ApplicationFiled: October 28, 2020Publication date: November 10, 2022Applicant: Impinj, Inc.Inventors: Christopher J.

Publication number: 20220313950Abstract: Guide extension catheters and related methods are disclosed. A guide extension catheter can comprise an elongate tube member, a push member, and a concave track. The elongate tube member can define a lumen and three distinct portions of different diameter. A distal portion can define a first diameter, a proximal portion can define a second diameter which is larger than the first diameter but smaller than a lumen of a guide catheter with which the guide extension catheter is used, and a tapered portion, positioned between the distal portion and the proximal portion, can have a variable diameter. The push member can be eccentrically coupled relative to the tube member and extends proximally therefrom for slidably positioning the tube member within and partially beyond a distal end of the guide catheter. The concave track forms a transition between the tube member and the push member, and defines a partially cylindrical opening leading into the tube member.Type: ApplicationFiled: June 17, 2022Publication date: October 6, 2022Applicant: Teleflex Life Sciences LimitedInventors: Joshua Brenizer, Dean Peterson, Mark Wendle
