Battery-powered percussive massage device

A method of massaging a body part using a battery-powered portable massage device having a main enclosure that houses a motor, the main enclosure having a proximal end and a distal end, the massage device having a piston that reciprocates along a reciprocation axis within the main enclosure in response to operation of the motor, the method comprising:

• coupling a removable applicator head to the piston via the distal end of the main enclosure;
• inserting a contact end of a battery assembly through a battery assembly receiving enclosure extending from the main enclosure;
• engaging at least a first contact and a second contact on the contact end of the battery assembly with at least a respective first contact and a respective second contact of a battery assembly receiving tray within the main enclosure;
• activating a power switch on a free end of the battery assembly to provide power to the main enclosure;
• selectively activating a control switch on the proximal end of the main enclosure to select a rotational speed for the motor;
• and
• gripping an outer gripping surface of the battery assembly between the contact end and the free end of the battery assembly, the outer gripping surface providing a handle to direct the application of the applicator head to a body part to be massaged.

A battery-powered percussive massage device comprising:

• a main housing that encloses a motor, the main housing extending between a proximal end and a distal end, the main housing enclosing a piston that reciprocates along a reciprocation axis in response to operation of the motor;
• an applicator head positioned at the distal end of the main housing and removably coupled to the piston, at least a portion of the applicator head exposed outside the distal end of the housing;
• a battery assembly receiving enclosure extending from the main housing at an angle with respect to the reciprocation axis;
• a battery assembly receiving tray positioned within the main housing in alignment with the battery assembly receiving enclosure, the battery assembly receiving tray having at least a first electrical contact and a second electrical contact;
• and
• a battery assembly having a contact end and a free end, the contact end positionable though the battery assembly receiving enclosure to engage the battery assembly receiving tray, the contact end supporting at least a respective first electrical contact to engage the first electrical contact of the battery assembly receiving tray and a respective second electrical contact to engage the second electrical contact of the battery assembly receiving tray, the battery assembly including an outer gripping surface positioned between the contact end and the free end, the outer gripping surface configured to be gripped by one hand.
