An IV adapter to allow for the mixing of multiple compatible medications with one another using a single bag of intravenous fluid. The IV adapter has multiple arms extending which gives rise to the ability to mix multiple medications. There is a spike within each arm to puncture the medication. The plurality of arms have built in mechanisms to control the flow of the medication and stop it from flowing in a certain direction. There are connections at the end of each arm allowing for a tight seal to be made to prevent any medication from leaking out of the IV line.

A device for treating a diseased native valve in a patient is provided, the device including a frame structure and a plurality of leaflets. The device can further include a spiral anchor configured to extend around an outer circumference of the frame structure. The anchor can be configured to deliver a contrast agent into or near a target tissue. Other embodiments and methods of use are also provided.

Disclosed is a microneedling device and a method for the microneedling of human or animal tissue. The method comprises the following steps; (a) providing a microneedling device having an electrically conductive microneedle and an electrically conducting nosepiece assembly spaced apart from the electrically conductive microneedle and acting as a counter electrode; (b) placing the electrically conductive microneedle and nosepiece assembly into contact with the tissue to be microneedled; (c) measuring the electrical impedance between the microneedle tip and the nosepiece or the current through the microneedle motor; (d) commencing insertion of the microneedle and moving the microneedle toward the tissue surface; (e) starting a step counter when the impedance reduces or the microneedle motor current increases; (f) incrementing the step counter with every step of the vertical drive motor until the step count reaches the prespecified value thereby controlling the depth of the hole microneedled.

A continuously hollow device for the transfer of fluids to the human body is provided, which is made in a nanomaterial derived from latex, which chemical composition in based primarily on fats, waxes and several gummy resins obtained from cytoplasm of lactic cells. This biochemically modified material is capable of adjusting its outer and inner diameter, i.e. it enlarges or shrinks according to the needs of the patient. The device corresponds to a needle or the like (catheter), which allows to have a very small diameter so as to be inserted in the patient (minimally invasive procedure) and after a physical excitation of such nanomaterial, it can be extended once inserted in the body so as to allow the intake or discharge of fluids to or from the body through a catheter, probe or the like.

A system is for contrast agent-based medical imaging. In an embodiment, the system includes a gantry of a medical imaging device; a contrast agent injection device; and a support arm including a frame element, a first connecting element and a second connecting element. In an embodiment, the frame element is connected to a stationary support frame of the gantry via the first connecting element such that at least part of the frame element is mounted to be movable relative to the stationary support frame of the gantry, and the contrast agent injection device is connected to at least part of the frame element via the second connecting element such that the contrast agent injection device is mounted to be movable relative to at least part of the frame element.

A method includes forming one or more vias in a first layer, forming one or more vias in at least a second layer different than the first layer, aligning at least a first via in the first layer with at least a second via in the second layer, and bonding the first layer to the second layer by filling the first via and the second via with solder material using injection molded soldering.

The present invention relates to methods for treating a microbial infection comprising administering a composition comprising one or more antibiotic compounds to the site of the infection by instilling the composition into the tympanostomy tube. A delivery cannula can be used to instill the composition into the tympanostomy tube.

An insertion system and a method for protecting an insertion device, for example, a needle, a catheter, a stent, etc., from infection and/or damage before, and/or during, and/or after insertion of the insertion device into an insertion site, are provided. The insertion system includes a hub or an introducer sheath with a hub, the insertion device, and an insertion device protection apparatus. The insertion device protection apparatus includes at least two elongate protective covers detachably engaged to each other and defining a channel extending through a length of the insertion device protection apparatus for enclosing the insertion device therewithin before, and/or during, and/or after inserting the insertion device into the insertion site. The elongate protective covers are progressively disengaged from each other from a proximal end and/or a distal end of the insertion device protection apparatus before, and/or during, and/or after insertion of the insertion device into the insertion site.

A system and method for determining the fill volume of a fluid chamber includes a fluid injector, at least one fluid chamber in fluid communication with the fluid injector, one or more sensors positioned relative to the at least one fluid chamber and configured to detect a position of a liquid-gas interface of the fluid contained in the at least one fluid chamber, and at least one processor in communication with the sensors and the fluid injector, and configured to: determine the position of the liquid-gas interface of the fluid, calculate the volume of fluid in the at least one fluid chamber based on the position of the liquid-gas interface, and at least one of: i) display the volume of the fluid; ii) enable the fluid injector to perform an action; and iii) disable the fluid injector from performing the action.
