The first aperture having a first portion extending from the outward facing side toward the patient facing side which is structured to be coupled to a delivery conduit and a patient side portion defined by a wall which extends outward from the patient facing side forming a hub. The device further includes a cushion having a patient contacting side which is structured to sealingly engage about an orifice or orifices of a patient, an opposite frame contacting side including a second aperture defined therein which is sized and configured to engage about the hub, and a second plurality of magnetic elements for magnetically coupling the cushion to the frame.

An implantable containment apparatus for receiving and retaining a biological moiety or a therapeutic device within a tissue bed is disclosed. The device includes a shaping element to maintain the device in a generally toroidal configuration and to return the apparatus to that configuration after deformation. The apparatus can be placed in a host tissue with minimal trauma to the patient. Methods for implanting and using the apparatus are also disclosed.

Cartridges for vaporizer devices are provided. In one exemplary embodiment, the cartridge can include first and second storage chambers each configured to hold a respective fraction of a vaporizable material, a vaporization chamber that includes an elongate member that is in fluid communication with the first and second storage chambers and configured to receive the vaporizable material, a magnetic element disposed within a channel of the elongate member, and a conductive element that is configured to generate a first motive force to drive the magnetic element between first and second positions and further configured to substantially vaporize the vaporizable material within the elongate member. Vaporizer devices are also provided.

A fluid management system for an ophthalmic surgical system includes an irrigation system and an aspiration system. The irrigation system carries fluid toward a handpiece and includes an irrigation pump or a plurality of pumps. The aspiration system carries fluid away from the handpiece and includes an aspiration pump or the plurality of pumps. The pumps include at least one magnetic pump configured to move the fluid. The magnetic pump includes a plug system and a magnetic field system. The plug system includes one or more plugs disposed within a housing, where each plug comprises a magnetic material. The magnetic field system generates a magnetic field to move one or more of the plugs in order to move the fluid in a pumping direction.

Methods and devices for positioning of subdural drain within an evacuated hematoma cavity. Embodiments include a tethered subdural drain with a puck attached to a leading end of a tether and a subdural drain attached to the terminal end of the tether. The puck is placed in vivo through a first hole in a cranium. A ex vivo guide manipulates the puck and tether through an evacuated hematoma cavity to be retrieved through a second hole in the cranium. Pulling the tether through the second hole advances the subdural drain attached thereto through the first hole and into the hematoma cavity.

A resuscitation management system for a manual resuscitator may include a radio frequency identification (RFID) tag that may be configured to be mounted on a first side of a bag of the manual resuscitator. The RFID tag may be configured to transmit information indicative of the presence of the RFID tag. The system may further include an RFID reader that may be configured to be mounted on an opposite second side of the bag. The RFID reader may be configured to generate an output signal corresponding to the presence of the RFID tag responsive to receiving the information transmitted by the RFID tag. The RFID reader may be configured to receive the information transmitted by the RFID tag responsive to the RFID tag being at a distance from the RFID reader smaller than a predetermined threshold.

Guidewires useful for cooperating with catheters may be actively steered and/or provide adjustable stiffness. Angle or curvature of a guidewire, and/or flexural modulus of a guidewire, may be adjusted at one or more locations between ends thereof. Variable stiffness segments may include electrically operated compressible and/or extensible materials. Multiple tensile elements may terminate at different body elements to adjust angle or curvature at multiple locations. Multiple circumferentially and/or radially contractible fiber regions may be provided and distributed over a length of a guidewire. Adjustable flexure elements arranged in or along a guidewire may be electrically operated. A flexible core member may be centrally arranged in a tubular body. A flexible guide wire or track may cooperate with electrically operable motor units.

Disclosed is a system for injecting a radioactive product to a patient, wherein the system includes: a first syringe containing the radioactive product, whose plunger cooperates with an injection mass, acting by gravity, associated with deactivatable holding element; a mobile stop arranged to constitute an end-of-travel stop for the retraction of the plunger, as a function of the volume of radioactive product to be injected to the patient; a second syringe containing a rinsing product, whose plunger cooperates with a rinsing mass, acting by gravity, associated with deactivatable holding element; a trigger control element for triggering the injection of the radioactive product to the patient; and a management element including a unit for displacing the mobile stop structure as a function of the prescribed activity to be injected to the patient, and a unit for controlling the deactivatable holding element of the masses.
