Publication number: 20180353194Abstract: A system for connection to a catheter to aspirate clot from the vasculature of a patient includes a vacuum console and a canister assembly which can be removably mounted in a mounting region of the vacuum console. The canister assembly includes a clear canister with an interior and an open top. A lid is removably attachable over the open top of the clear canister, and the clear canister has a vacuum port and a pressure sensing port each formed in a wall of the canister. The vacuum port aligns with a vacuum connector on the enclosure and the pressure sensing port aligns with a pressure sensing connector on the enclosure when the canister assembly is mounted on the mounting region of the vacuum console. The clear canister has a filter plate configured to be suspended in the interior of the clear canister at a location mid-way between the open top and a bottom to separate clot from blood as they are aspirated from the catheter.Type: ApplicationFiled: June 5, 2018Publication date: December 13, 2018Applicant: Penumbra, Inc.Inventors: Robyn Shaffer, Stephen Pons, Kyle West, Alex Rabkin, Sharice Quan Handa, Robert A.

Publication number: 20180228502Abstract: A catheter includes a shaft having a proximal end, a distal end, and a central lumen extending continuously from the proximal end to the distal end. A hypotube forms a proximal region of the shaft, and a polymer tube forms a distal region of the shaft. A periphery of the hypotube is cut in a pattern which provides a decreasing stiffness in a proximal-to-distal direction, and in some embodiments the polymer tube is reinforced by a wire embedded over at least a portion of the polymer tube's length. A guidewire lumen is disposed at or near the distal end of the catheter and extends for a portion of the catheter's length. The catheter may be used for aspiration, device delivery, or other purposes in a patient's vasculature.Type: ApplicationFiled: February 9, 2018Publication date: August 16, 2018Applicant: Penumbra, Inc.Inventors: Robyn Shaffer, Holly Sit

Publication number: 20180197633Abstract: A system for treatment of ischemic stroke provides a stroke treatment workflow plan defining series of diagnostic actions and therapeutic actions to be performed at locations within a health care facility identified by beacons detectable by proximity sensors that travel with the patient. A first communications device having wireless communications capabilities receives a signal from a proximity sensor and typically transmits data to a second communications device having a visible timer and configured to receive data from and send data to other wireless communications devices. When the a patient undergoes diagnosis and treatment via the workflow plan, the system tracks the location of the patient within the workflow plan and the time at which the patient is at each location, and records the location of the patient and the time of the location within the workflow plan.Type: ApplicationFiled: March 9, 2018Publication date: July 12, 2018Applicant: Penumbra, Inc.Inventor: Brijesh P.

Publication number: 20170367857Abstract: A system for mechanically deploying intraluminal implants is disclosed. The system is used with an implant that is delivered and/or deployed via a pull wire and includes a handle having a funnel and receiving channel for receiving the pull wire, a slider having a thumb grip and a wedge, and a shuttle having a grabber for grasping the pull wire. The thumb grip is pulled proximally to retract the wedge to cause the grabber to grasp the wire and retract the shuttle but not the wire. An extension spring linked between the slider and the shuttle abruptly pulls the shuttle to retract the pull wire after the slider is fully retracted.Type: ApplicationFiled: March 6, 2017Publication date: December 28, 2017Applicant: Penumbra Inc.Inventors: Eric Bennett, Erin Vitus, Matt Vargas, Arani Bose, Stephen Pons, Ben Tompkins, David Barry

Publication number: 20170360450Abstract: Embolic coil implant systems and methods whereby coils are mechanically detachable are disclosed. The coils include a retention element that may be releasably retained within the distal end of an implant tool. The implant tool may include a fulcrum configured to engage a first filament and prevent the release of the coil when the first filament is engaged. Alternatively, an urging means and aperture may be disposed within the sidewall of the implant tool, and a first filament may, in conjunction with the aperture and sidewall, releasably retain the coil until the first filament is withdrawn. The implant tool may also include an alignment member for aligning the first filament.Type: ApplicationFiled: August 30, 2017Publication date: December 21, 2017Applicant: Penumbra, Inc.Inventors: Ben Tompkins, Arani Bose, Delilah Hui, David Barry, Stephen Pons, Aleksander Leynov

Publication number: 20170340797Abstract: Doxorubicin is extracted from blood using anionic material, such as a resin comprising sulfonated polystyrene divinylbenzene beads, and polyethersulfone membrane, or both. After exposing the resin and/or membrane to blood in order to remove doxorubicin therefrom, the doxorubicin maybe extracted from the resin and/or membrane by exposing the material to an extraction solution, sonicating the extraction solution to enhance release of the doxorubicin, and repeating the exposure and sonication in order to remove substantially all of doxorubicin from the resin.Type: ApplicationFiled: May 30, 2017Publication date: November 30, 2017Applicant: Penumbra, Inc.Inventors: Karthik Raman, Colin Yee, Chia-Hung Sze, Arthur John Lockhart, David Barry
