Patent number: 12336749Abstract: A forceps includes an end effector assembly having a stop and a plurality of overmold teeth within at least one jaw member. One (or both) of the jaw members is moveable relative to the other between a spaced-apart position and an approximated position for grasping tissue therebetween. One (or both) of the jaw members includes a stop molded within an insulative housing, and an insulator plate with the overmold teeth formed from plastic. The overmold teeth extend through openings within a sealing plate and protrude past the tissue sealing surface of the sealing plate. The stop primarily controls the gap distance between opposing jaw members by bearing most of an applied load and the overmold teeth assist in controlling the gap distance by bearing the remaining applied load.Type: GrantFiled: November 7, 2022Date of Patent: June 24, 2025Assignee: Covidien LPInventors: John R.

Patent number: 12341463Abstract: A blood pump system includes a blood pump and a corresponding controller. The blood pump includes an impeller that is sealed within the pump housing and hydrodynamically suspended within the pump housing. The pump impeller includes magnets, and is the rotor of a brushless direct current (DC) motor that is driven by electrical signals through stator wire coils in the pump housing, which creates a rotating magnetic field. The rotating magnetic field attracts the magnetized impeller and spins it with the rotating field. The controller provides field-oriented control for the brushless DC motor in the blood pump. The field-oriented control in the controller is provided in a programmable logic device separate from a control processor so that a software or hardware failure related to the control processor does not stop the blood pump. The field-oriented control allows sensing blood flow through the pump without having sensors in the blood stream.Type: GrantFiled: June 6, 2022Date of Patent: June 24, 2025Assignee: STAR BP, INC.Inventors: Jared D. Allen, Sean K. Barry, Dana G. Pelletier, J. Ryan Stanfield
