The present technology is generally related to attachment mechanisms for controllers and batteries of implantable medical devices, and in particular, controllers and batteries for implantable blood pumps.
External controllers for implantable blood pumps not only control, at least in part, operation of the implantable blood pump, but also connect with a battery which supplies power to the controller and the implantable blood pump. The batteries provide a certain charge time, for example, a few hours, and then are recharged and recoupled to the controller. Thus, the user repeatedly attaches and detaches batteries to the controller, which may increase the prevalence of the controller and battery getting jammed together and being unable to attach or detach.
The techniques of this disclosure generally relate to attachment mechanisms for controllers and batteries of implantable medical devices, and in particular, controllers and batteries for implantable blood pumps.
In one aspect, the present disclosure provides an attachment mechanism between a controller for an implantable blood pump and a battery housing. The attachment mechanism includes a latch moveably coupled to the controller. The latch includes a pawl configured to engage the battery housing. The latch is configured to only pivot when the battery housing is engaged to the pawl during attachment of the battery housing to the controller.
In another aspect of this embodiment, the controller includes at least one pivot slot configured to engaged at least one corresponding pivot tab on the battery housing.
In another aspect of this embodiment, the latch is configured to only pivot when the battery housing is disengaged from the pawl during detachment of the battery from the controller.
In another aspect of this embodiment, the latch is coupled to a spring.
In another aspect of this embodiment, the latch includes an actuator, and wherein the actuator is movable.
In another aspect of this embodiment, the spring is axially aligned within pawl and substantially perpendicular to the actuator.
In another aspect of this embodiment, the latch pivots about a pin.
In another aspect of this embodiment, the pawl includes a projection at its distal end.
In another aspect of this embodiment, when the battery housing is attached to the controller, the controller is in electrical communication with a battery within the battery housing.
In one aspect, an attachment mechanism between a controller for an implantable blood pump and a battery housing includes a latch moveably coupled to the controller. A strike plate is coupled to the battery housing. The latch includes a pawl configured to engage the strike plate. The latch is configured to only pivot when the strike plate is engaged to the pawl during attachment of the battery housing to the controller.
In another aspect of this embodiment, the controller includes at least one pivot slot configured to engage at least one corresponding pivot tab on the battery housing.
In another aspect of this embodiment, the latch is configured to only pivot when the strike plate is disengaged from the pawl during detachment of the battery housing from the controller.
In another aspect of this embodiment, the latch is coupled to a spring.
In another aspect of this embodiment, the latch includes an actuator, and wherein the actuator is movable.
In another aspect of this embodiment, the spring is axially aligned within pawl and substantially perpendicular to the actuator.
In another aspect of this embodiment, the latch pivots about a pin.
In another aspect of this embodiment, the pawl includes a projection at its distal end.
In another aspect of this embodiment, the projection engages the strike plate.
In another aspect of this embodiment, when the battery housing is attached to the controller, the controller is in electrical communication with a battery within the battery housing.
In one aspect, an attachment mechanism between a controller for an implantable blood pump and a battery housing includes a latch moveably coupled to the controller. A strike plate is coupled to the battery housing. The controller includes a pair of pivot slots configured to engage a pair of corresponding pivot tabs on the battery housing. The latch includes a pawl configured to engage the strike plate. The latch is configured to only pivot when the strike plate is engaged to the pawl during attachment of the battery housing to the controller. The latch is configured to only pivot when the strike plate is disengaged from the pawl during detachment of the battery housing from the controller.
The details of one or more aspects of the disclosure are set forth in the accompanying drawings and the description below. Other features, objects, and advantages of the techniques described in this disclosure will be apparent from the description and drawings, and from the claims.
A more complete understanding of the present invention, and the attendant advantages and features thereof, will be more readily understood by reference to the following detailed description when considered in conjunction with the accompanying drawings wherein:
It should be understood that various aspects disclosed herein may be combined in different combinations than the combinations specifically presented in the description and accompanying drawings. It should also be understood that, depending on the example, certain acts or events of any of the processes or methods described herein may be performed in a different sequence, may be added, merged, or left out altogether (e.g., all described acts or events may not be necessary to carry out the techniques).
