A medication delivery system having a holding chamber capable of delivering dosages of medicament from a metered dose inhaler. The holding chamber includes an actuator detector, flow detector and display. In another embodiment, a medication delivery system includes a holding chamber having an input and an output end, a metered dose inhaler operably coupled to the input end of the holding chamber, and a metered dose inhaler identifier associated with the holding chamber and operable to identify the metered dose inhaler coupled to the holding chamber.

A medical device includes at least one ionic electroactive polymer actuator, the actuator including at least one polymer electrolyte member defining at least a surface and a plurality of electrodes disposed about the surface of the at least one polymer electrolyte member, an elongate, flexible portion defining a proximal end and a distal end secured adjacent to the ionic electroactive polymer actuator and the elongate, flexible portion further comprising a core and a sleeve surrounding the core and a plurality of electrically-conductive wires, each having a proximal end and a distal end coupled to at least one of the plurality of electrodes, wherein the at least one polymer electrolyte member deforms asymmetrically in response to the application of an electrical potential supplied through at least one of the plurality of electrically-conductive wires to at least one of the plurality of electrodes.

In some examples, a catheter includes an elongated body that includes a proximal portion and a distal portion, and one or more electroactive elements in at least one of the proximal portion or the distal portion of the elongated body. The one or more electroactive elements each include a contractive material configured contract in response to an application of an electrical signal to the respective electroactive element. The contraction of the electroactive elements is configured to change a dimension or a shape of the elongated body. The electroactive elements may be distributed around the elongated body at the distal portion of the elongated body, such as in different axial or radial positions. The electroactive elements may comprise a nickel titanium (NiTi) alloy having a Ni:Ti composition of about 50:50.

A respiratory assistance component is disclosed that changes shape when an electrical charge is provided. The amount of electrical charge that is applied may be based on values, characteristics, or user controlled parameters of the respiratory assistance system. The component may be all or part of a patient interface, a tube, a flow generator, and/or a sleep mat.

Delivery devices, systems, and methods for delivering implantable leadless pacing devices are disclosed. An example delivery device may include a tubular member and a distal holding section extending distally of a distal end of the tubular member and defining a cavity therein for receiving an implantable leadless pacing device. The delivery device may facilitate vascular delivery of the pacing device to a left side of a patient's heart. In one example, a distal tip portion may extend distal of the distal holding section and may be actuated between a closed and an opened position. When in the closed position, the distal tip portion may have a tip that can puncture or engage an opening in a septum between a left atrium and a right atrium of a patient's heart. Actuating the distal tip portion to an opened position may be utilized to dilate the puncture or opening in the septum.
