MULTI-CATHETER INFUSION SYSTEM AND METHOD THEREOF
A multi-catheter infusion system and method for the localized delivery of medications while minimally affecting patient mobility for an extended period of time. The multi-catheter infusion system includes a cannula and a plurality of catheters. The cannula includes a first end for connecting to a drug delivery system and a second end for connecting to the plurality of catheters. The plurality of catheters are in fluid communication with the cannula for delivering a drug to a target area of a patient. Each catheter includes a multi-orifice distal end.
Dural repair device and method of use
Dural repair devices that are configured to effectively and reliably repair the damage of a dural tear due to incidental durotomies are provided, along with methods of use. The devices and methods enhance the ability of a surgeon to repair a patients dura mater, or dura, during surgery of the central nervous system. The dural repair device has a multi-layer structure configured to exert a pressure or tamponade effect to compress a patient's dura to its state prior to the spinal surgery. Thus, the dural repair devices and methods of use may reduce the patients risk morbidity, further surgery, spinal headaches, or other injuries and discomforts.
SUBDURAL DRAINAGE CATHETER WITH SELF CONTAINED MECHANISM FOR RESTORATION OF FLOW FOLLOWING CATHETER OBSTRUCTION
A subdural drainage device includes a subdural drainage housing defining a drainage passageway. The drainage passageway has a A subdural drainage device includes a subdural drainage housing defining a drainage passageway. The drainage passageway has a lower opening configured to connect to a subdural space of a patient and an upper opening. A blockage removal unit is in the housing, and the blockage removal unit has an end portion that is configured to reduce or remove blockages adjacent the lower opening of the drainage passageway that is movable between a retracted position in which the end portion is in the subdural drainage housing and an extended position in which the end portion of the blockage removal unit extends away from the subdural drainage housing via the lower opening of the drainage passageway. At least one side delivery port is in the housing and in fluid communication with the drainage passageway.
DEVICES AND METHODS FOR DRAINAGE, INFUSION, OR INSTILLATION OF FLUIDS
Valve devices are provided for draining fluids from and/or infusing fluids into a patient's body that include a housing including first, second, and third connectors, a primary fluid path communicating between the first and second connectors, and a secondary fluid path communicating from the primary fluid path to the third connector. First and second valve members are movable within the housing between first positions wherein the valve members do not obstruct the primary fluid path and second positions wherein the primary fluid path is at least partially closed. The third connector may be configured to prevent fluid flow therethrough unless a mating connector is fully coupled thereto. The valve members may be selectively closed to isolate portions of the flow path to allow a source of vacuum or fluid coupled to the third connector to aspirate or infuse fluid along portions of the primary fluid path.
Surgical instrument ports configured for use with wound retractors, and related devices and methods
A surgical port includes an end face with a channel extending through the end face. The channel has a cross section shaped to receive a surgical instrument cannula. A lateral wall extends around a perimeter of the end face. The lateral wall and end face enclose an open volume. A rim extends radially inward from the lateral wall and projects into the open volume. An apron portion extends radially outward from the lateral wall and in a direction axially away from the end face. Surgical systems may include surgical ports. Methods relate to using surgical ports.
DEVICES FOR USE WITH SURGICALLY CREATED ORIFICES
A device for connecting and transferring contents between a surgically created first orifice and a surgically created second orifice is provided. The device comprises a hollow body member and first and second tubular legs depending from the hollow body, and being adapted for insertion into the first and second surgically created orifices respectively. The device further comprises a cap for closing the hollow body and completing a sealed pathway between the tubular legs for passively conveying contents between the first and second surgically created orifices. Sealing features of the device are provided that in combination operate to keep the contents away from unwanted skin areas and/or provide an easy-to-use device.
ANTI-THROMBTIC MEDICAL INSTRUMENT AND CATHETER
The present invention relates to a an anti-thrombotic medical instrument and catheter medical instrument comprising: base with a port for connection to an infusion set; a catheter extending from the base, and comprises a main body of tubular configuration. a plurality of lateral conduits distributed along the length of the catheter; an elastomeric cover over each lateral conduit, said elastomeric cover opens with a fluid flow inside the catheter and closes when the fluid flow stops. Said lateral conduits have an angle in the range of 15° to 60° to the longitudinal axis of the catheter.
SURGICAL INSTRUMENT PORTS CONFIGURED FOR USE WITH WOUND RETRACTORS, AND RELATED DEVICES AND METHODS
A surgical port includes an end face with a channel extending through the end face. The channel has a cross section shaped to receive a surgical instrument cannula. A lateral wall extends around a perimeter of the end face. The lateral wall and end face enclose an open volume. A rim extends radially inward from the lateral wall and projects into the open volume. An apron portion extends radially outward from the lateral wall and in a direction axially away from the end face. Surgical systems may include surgical ports. Methods relate to using surgical ports.
ASPIRATION CONTROL VALVE
An aspiration control device can have an aspiration control valve and a switch, button, slider, trigger, grip, lever, rotating wheel, rotating valve, handle or other interface for resizing the aspiration control valve. The aspiration control interface can be conveniently positioned and configured to be manipulated while simultaneously stabilizing a catheter and/or retracting an elongated member. The aspiration control device can be integrated with a hemostasis valve, integrated with a wire gripping device, and/or attached to an inlet, outlet, hose, pump, or syringe in series with an aspiration flow path.
IMPLANTABLE ENCAPSULATION DEVICES
The present disclosure relates to implantable encapsulation devices for housing a biological moiety or a therapeutic device that contains a biological moiety. Particularly, aspects of the present disclosure are directed to an implantable apparatus that includes a distal end, a proximal end, a manifold including at least one access port positioned either at the distal end or the proximal end, and a plurality of containment tubes affixed to the manifold and in fluid communication with the at least one access port. Additionally, the encapsulation device may contain a flush port and a tube that are fluidly connected to the manifold. The containment tubes may contain therein a biological moiety (e.g., cells) or a therapeutic device (e.g. a cell encapsulation member).
