Publication number: 20200376177Abstract: An apparatus (10) for controlling flow of fluid from a wound site of a patient including a cavity (28) connectable to a wound site and a reservoir (16). The cavity (28) may have a first deformed state, and a second state in which it is not deformed or less deformed than in the first state. The cavity (28) may be adapted to manage fluid flow between the wound site and the reservoir (16) during transition of the cavity (28) between the first state and the second state. An actuator element (64) of the apparatus (10) may be adapted to operate on the chamber (28) to transition the cavity (28) from the second state to the first state.Type: ApplicationFiled: August 17, 2020Publication date: December 3, 2020Inventor: Landy Aaron Toth

Publication number: 20200376178Abstract: The illustrative embodiments described herein are directed to an apparatus, system, and method for storing liquid from a tissue site. The apparatus may include a drape having an aperture, and a fluid pouch coupled to the drape such that the fluid pouch is in fluid communication with the aperture. In one embodiment, the fluid pouch is operable to transfer reduced pressure to the aperture such that the liquid from the tissue site is drawn into the fluid pouch. The fluid pouch may have a cavity that stores the liquid that is drawn from the tissue site. In another embodiment, the fluid pouch may include at least one baffle. The fluid pouch may also include a fluid channel at least partially defined by the at least one baffle. The fluid channel may be operable to store liquid from the tissue site when reduced pressure is applied through the fluid channel.Type: ApplicationFiled: August 19, 2020Publication date: December 3, 2020Inventors: Richard Daniel John COULTHARD, Timothy Mark ROBINSON, Christopher Brian LOCKE, Aidan Marcus TOUT

Publication number: 20200376181Abstract: There is provided an intravascular blood pump for insertion into a patient's body. The system comprises a slotless motor having p magnet pole pairs and n phases, where p is an integer greater than zero, and n is an integer ?3. The motor comprises a stator winding having 2np coils wound to form two coils per phase per magnet pole pair such that a coil from each phase is circumferentially arranged next to a coil from a different phase in a sequential order of phase, the arrangement repeated along the stator winding such that each coil spans 360°/(2np) about the cross section of the stator winding. The motor also comprises a permanent magnet rotor supported for rotation and configured to generate a magnetic flux for interaction with the stator winding. The two coils per phase per magnet pole pair are connected in series.Type: ApplicationFiled: May 21, 2020Publication date: December 3, 2020Inventor: Jimpo Wang

Publication number: 20200376182Abstract: A blood pump comprises a pump casing having a blood flow inlet and a blood flow outlet, and an impeller arranged in said pump casing and rotatably supported in the pump casing by a bearing so as to be rotatable about an axis of rotation. The impeller has blades for conveying blood from the blood flow inlet to the blood flow outlet. The bearing comprises at least one stationary bearing portion coupled to the pump casing and having a stationary bearing surface that faces radially outwards. The bearing further comprises a rotating bearing surface interacting with the stationary bearing surface to form the bearing, wherein the rotating bearing surface faces radially inwards and is formed on an exposed radially inner edge of the blades. The blades are designed to draw blood deposit on the stationary bearing surface in a radially outward direction.Type: ApplicationFiled: August 19, 2020Publication date: December 3, 2020Applicant: Abiomed Europe GmbHInventors: Thorsten Siess, Walid Aboulhosn, Wolfgang Kerkhoffs, Ellen Keysselitz, Peter Skrodsky
