Patent number: 11950800Abstract: A catheter for scoring or slicing a lesion. The catheter has a first receiver at a distal end of an expandable portion of the catheter shaft. A first carrier at least partially within the first receiver is moveable axially along the catheter shaft to deploy a first cutter along the expandable portion for cutting or scoring the lesion. In an alternative embodiment, the first carrier may be a wire having a loop, and thus forming a first length including the first cutter and a second length including a second cutter. Actuation of the wire thus causes simultaneous, reciprocal movement of the first and second cutters. Related methods are also disclosed.Type: GrantFiled: June 18, 2021Date of Patent: April 9, 2024Assignee: C.R. BARD, INC.Inventors: Andrzej Chanduszko, Michael Randall, Chad Van Liere

Publication number: 20230032423Abstract: A low-profile access port for subcutaneous implantation within a patient. The access port can include a set of receiving cups which can be placed in fluid communication with a catheter. The set of receiving cups can provide a greater skin surface with which to access the port to avoid repeated penetrations at a single locus, such as during consecutive dialysis treatments. The access port can alternatively include needle penetrable arms or elongate chambers that also have a slim, low profile. The access port can include a needle guide to direct subsequent needle access to different insertion points to permit healing at the previous insertion points. The access port can be formed of a modular construction with a first conduit, a second conduit, and an outer shell. The outer shell can include a proximal portion and a distal portion. The access port can include a stem assembly and a locking member.Type: ApplicationFiled: October 11, 2022Publication date: February 2, 2023Inventors: Brenda L. F. Fedor, Jason R. Stats, Michael A.

Patent number: 11166121Abstract: Systems and methods are provided for receiving a first message associated with a first sponsor and a second message associated with a second sponsor for inclusion in a message collection. The systems and methods determine a first priority parameter associated with the first message based on sponsored content, and a second priority parameter associated with the second message based on sponsored content. Based on a determination that there is insufficient message inventory to include both the first message and the second message in the message collection, the systems and methods prioritize the first message associated with the first sponsor in the message collection and excluding the second message associated with the second sponsor in the message collection, based on an amount of consideration associated with the first priority parameter received from the first sponsor and an amount of consideration associated with the second priority parameter received from the second sponsor.Type: GrantFiled: June 25, 2020Date of Patent: November 2, 2021Assignee: Snap Inc.Inventors: Timothy Michael Sehn, Juan David Borrero, Michael Randall, Brian Ames
