A medical device used for implanting in a body includes a main body, a container included in the main body, and an insulating soft portion that closes an opening of the container. An electrically conductive first conductive portion is disposed on a bottom of the container, and an electrically conductive second conductive portion disposed on the main body. The first conductive portion and the second conductive portion are electrically connected to each other.

A system for refilling a multi-chamber implantable infusion device is presented. The infusion device has a refill chamber which is accessible through an external septum of a refill port. The refill chamber is divided by an inner septum into an upper reservoir and a lower reservoir. The lower refill chamber is refilled with lower reservoir needles having a needle opening axially placed to align with the lower reservoir. The upper reservoir is refilled with an upper reservoir needle having an opening aligned with the upper reservoir. Magnetic portions are provided in the needles to localize and identify the needle. A processor within the infusion device is connected to magnetic field sensors which sense magnetic portions of the needle and recognize information encoded magnetically within the needle.

[Problem] To accurately check a usage status of a medical product such as a damage status of the medical product or existence or nonexistence of the medical product.

[Solution] A medical product (80) is configured to include a light-emissive septum (83) (constituent member) which includes a luminescent agent emitting near-infrared fluorescence according to irradiation of excitation light on a surface thereof. Even in a case where a portion of the septum is separated as a core (83a) (separate piece) due to damage, the luminescent agent is also included on a surface of the core. A medical product usage status checking apparatus (10) is configured to include a medical product which emits the near-infrared fluorescence, an irradiation unit (130) which irradiates the medical product with excitation light which excites the luminescent agent, an optical filter (140) which blocks the excitation light and transmits the near-infrared fluorescence emitted by the luminescent agent, a camera (15) (imaging unit) which receives the near-infrared fluorescence passing through the optical filter, and a monitor (160) (display unit) which displays an image captured by the camera. An image based on the near-infrared fluorescence of the septum is displayed on the monitor and in a case where damage occurs in the septum, an image based on the near-infrared fluorescence of the core is displayed on the monitor.

A fluid connector assembly is disclosed. The fluid connector assembly includes a body portion, a plug portion located on the body portion, the plug portion comprising a fluid path, a tubing, a first end of the tubing fluidly connected to the plug fluid path, a catch feature located on a first end of the body portion and configured to interact with a reservoir, and a latching feature located on a second end of the body portion, the latching feature configured to interact and lock onto the reservoir.

A cardiac assist system includes a pneumatic effector which is implanted beneath a pericardial sac and over a myocardial surface overlying the patient's left ventricle. A port is implanted and receives a percutaneously introduced cannula. The port is connected to supply a driving gas received from the cannula to the pneumatic effector. An external drive unit includes a pump assembly and control circuitry which operate the pump to actuate the pneumatic effector in response to the patient's sensed heart rhythm. A connecting tube has a pump end connected to the pump and a percutaneous port-connecting end attached to the implantable port.

An implantable pump configured to enable tuning of a delivery velocity of a fixed quantity of medicament. The implantable pump including a pump, an accumulator and a valve configured to enable tuning of a delivery velocity of a fixed quantity of medicament, wherein operating the pump with the valve continuously in the open state enables a steady-state delivery of medicament at a first velocity, and wherein closing of the valve enables the pump to at least partially fill the accumulator and subsequent opening of the valve enables the at least partially filled accumulator to dispense medicament, thereby delivering a bolus of medicament at a second velocity, wherein the second velocity is greater than the first velocity.

An apparatus to determine if a constituent member has been damaged. The constituent member can be a medical product comprising a coating, or a substance kneaded into the product, which emits a fluorescence in the near-infrared region. The apparatus to determine if this constituent member has been damaged includes an irradiation light source, an optical filter, an imaging unit, a display unit and a control unit connected to the light source, the optical filter and the imaging unit to determine and inform that damage has occurred in the constituent member.

In some examples, an implantable infusion device using a piezoelectric and/or electrostrictive mechanical pumping catheter includes a reservoir configured to retain for a fluid to be dispensed within a patient, at least one piezoelectric and/or electrostrictive mechanical pumping catheter for dispensing the fluid contained within the reservoir, a transceiver, and a processor to regulate control the operation of the piezoelectric and/or electrostrictive mechanical pumping catheter.

A medical device that can confirm a predetermined portion in a medical instrument implanted for use in a body. A medical instrument includes a main body part, and a medicinal solution container installed in the main body part. A notification part includes a plurality of light emitting portions that emit light by use of power received by a power receiving part to notify that a predetermined state is reached, when a relative positional relation between a power transmission part and the power receiving part reaches the predetermined state by moving the power transmission part, and a soft part into which an injection needle is inserted, the plurality of light emitting portions are arranged along an outer edge of the soft part. A first coil is a coreless coil disposed to have an inner diameter larger than an outer diameter of the medicinal solution container.

Embodiments of the present disclosure provide a system and method configured to provide feedback to a user during a refill procedure for an implantable medical device via an external refilling apparatus through the use of resilient tactile feedback element within the refill port chamber that provides tactile feedback to a user of a refill needle of a location of the needle within the refill port.
