Publication number: 20210378850Abstract: A drainage stent delivery system is disclosed. The drainage stent delivery system includes a catheter body, a stent member, and a coupling member. In some embodiments the coupling member can include keyed connectors having a non-round shape to facilitate a 1:1 rotation ration of the catheter body and the stent member. In another embodiment, the coupling member can include a telescoping connector having an inner tube and a release wire disposed through the inner tube. A distal portion of the release wire has an outer diameter greater than an inner diameter of the inner tube such that the telescoping connector can be displace by the release wire. In another embodiment, the stent member includes a proximal retention member having arms that are outwardly extendable.Type: ApplicationFiled: June 2, 2021Publication date: December 9, 2021Inventors: Nicholas Accisano, III, Kent C. Stalker

Patent number: 8708933Abstract: The invention is directed to a guidewire having a distal section with multiple distally tapered core segments with at least two contiguous distally tapering core segments in which the most distal tapered core segment preferably has a greater degree of taper than the proximally contiguous tapered core segment. The invention is also directed to an elongated intracorporeal device, preferably a guidewire or section thereof, that has a core member or the like with a plurality of contiguous tapered segments having taper angles that are configured to produce a linear change in stiffness over a longitudinal section of the device. The device may also have a core section with a continuously changing taper angle to produce a curvilinear profile that preferably is configured to produce a linear change in stiffness of the core over a longitudinal section of the device.Type: GrantFiled: November 12, 2012Date of Patent: April 29, 2014Assignee: Abbott Cardiovascular Systems Inc.Inventors: Wayne E. Cornish, John Schreiner, James M. Jacob, Marc M. Jalisi, Mark T. Richardson, Kent C. Stalker, Olin J. Palmer
