Abstract: A drain cassette for a dialysis unit has a fluid channel between venous and arterial connection ports, and a valve may controllably open and close fluid communication between a drain outlet port and the venous connection port or the arterial connection port. A blood circuit assembly and drain cassette may be removable from the dialysis unit, e.g., by hand and without the use of tools. A blood circuit assembly may include a single, unitary member that defines portions of a pair of blood pumps, control valves, channels to accurately position flexible tubing for an occluder, an air trap support, and/or other portions of the assembly. A blood circuit assembly engagement device may assist with retaining a blood circuit assembly on the dialysis unit, and/or with removal of the assembly. An actuator may operate a retainer element and an ejector element that interact with the assembly.

Abstract: A method and shunt device for treating glaucoma includes positioning a first end portion of a tube body into the retrobulbar space of an eye. The method also includes positioning a second end portion of the tube body into the anterior chamber of the eye. The tube body provides fluid passage for aqueous humor such that the aqueous humor flows from the first end portion into the retrobulbar space. A surgical kit for reducing the intraocular pressure in the eye includes the shunt device, an introducer, and a stylet. The introducer has a distal end for positioning in the retrobulbar space and a proximal end for positioning exterior of the eye. The introducer has a radius of curvature adapted to circumvent the eye for insertion into the retrobulbar space.
Abstract: Devices and methods for wound treatment are disclosed. A chamber may define a treatment space having an interior engineered surface including a plurality of structures configured to provide pathways for the distribution of negative pressure and to exert mechanical stress on a wound. In some specific embodiments, the devices and methods may treat wounds on the head, neck, and face. One or more tubes may be in fluid communication with the treatment space to facilitate the application of negative pressure, the introduction of therapeutic agents, and the removal of wound material.
Abstract: A method of draining cerebrospinal fluid from a human brain. The method includes providing a drainage catheter having a proximal end and a distal end. The drainage catheter has a plurality of openings formed therein. The plurality of openings includes a first opening, a second opening, and a most proximal opening. The second opening is disposed closer to the distal end than the first opening. A cross-sectional area of the first opening is less than a cross-sectional area of the second opening. The distal end of the drainage catheter is inserted into a human brain. Cerebrospinal fluid is drained from the human brain. The cerebrospinal fluid passes into the drainage catheter through the plurality of openings and out of the drainage catheter through the proximal end. A rate at which the cerebrospinal fluid passes through the drainage catheter is controlled to maintain intracranial pressure within a selected range.
Abstract: An IOP control system for treatment of an ocular condition includes a drainage device sized for implantation into the eye of the patient, the drainage device including a fluid flow pathway to allow the flow of fluid from an inlet port to an outlet port. The drainage device also includes a flow system disposed within the drainage device and including a displaceable portion forming a part of the fluid flow pathway, the displaceable portion being displaceable via a magnetic field. An actuation system may be physically separate from the drainage device and may be configured to cooperate with the displaceable portion to displace the displaceable portion via the magnetic field to set free buildup or debris in the flow pathway.

In a second group of embodiments, the invention provides devices with specialized ends for connecting the devices to conventional medical tubing to divert fluid trapped in an organ to a destination selected by the practitioner. The invention further provides systems and methods of using the devices.
Abstract: An adaptor for coupling with a vial having a collar closed by a septum, the septum having an outer surface directed towards the outside of the vial, the adaptor comprising: a gripping member for securing the adaptor to the vial, the gripping member being capable of being laterally mounted on the collar of the vial and a pierceable elastomeric piece having at least a part intended to be in contact with the outer surface of the septum when the adaptor is secured on the vial. Also, an assembly including such an adaptor and a vial.
Abstract: One disclosed embodiment comprises a method for treating lesions in the carotid artery of a mammalian body. The method comprises transcervical access and blocking of blood flow through the common carotid artery (with or without blocking of blood flow through the external carotid artery), shunting blood from the internal carotid artery and treating the lesion in the carotid artery.
Abstract: A system for filtering or treating blood of a subject is provided herein. The system includes a bone port for establishing fluid communication with a bone marrow of the bone and a return port for returning blood from the bone marrow to a circulation of the subject. The system further includes a blood treatment or filtering device interposed between the bone and return ports thereby establishing a mini-circulatory system.
Abstract: A hermetically-sealed plastics container for blood derivative products is provided. The container may have an internal surface and an external surface, characterized in that it comprises an RFID inlay between the internal surface and the external surface.

Abstract: Devices and methods for treating heart disease by normalizing elevated blood pressure in the left and right atria of a heart of a mammal are disclosed. The devices are adapted to permit fluid flow across the membrane in which the device is implanted at first rate, and at a second rate, wherein a difference between the first rate and the second rate is not solely dependent upon variations in blood pressure differential across the membrane due to the heart's pumping cycle.
