  • Patent number: 8771220
    Abstract: In various embodiments, a glaucoma shunt may include a tube having an anterior portion (with an opening) and a posterior portion. The glaucoma shunt may include a valve, inside the tube, coupled to a drainage portion. The tube may be configured to couple to a first portion of an eye and the drainage portion may be configured to couple to a second portion of the eye. In some embodiments, the drainage portion may be configured to move the valve relative to the tube such that when the eye expands, the valve moves away from the opening in the anterior portion of the tube to increase fluid flow. The drainage portion may further be configured to move the valve relative to the tube such that when the eye contracts, the valve moves toward the opening in the anterior portion of the tube to decrease fluid flow.

These tools allow a medical professional to locate and non-invasively determine the setting of an implanted valve. After the valve has been located and the setting of the valve determined, the valve may be re-adjusted non-invasively. There are three tools: a locator tool, an indicator tool and an adjustment tool. The locator tool allows the physician to locate the adjustable valve of interest and align the locator tool with a specific orientation of the valve. The indicator tool indicates the current setting of the adjustable valve and confirms new settings of the valve after the new settings have been implemented. The adjustment tool interacts magnetically with the implanted adjustable valve to couple with a movable internal element to change the setting of the valve. The indicator tool and the adjustment tool physically cooperate with the locator tool to accomplish the respective functions of the tools.

  • Patent number: 8685001
    Abstract: A device and method for the removal and disposal of transected hair from the body of a patient in an operating room or other sterile location. The hand-held device is single-use, latex-free, sterile-packaged, non-conductive, fully disposable and comprises a hollow handle with a projecting wand ending in an enlarged distal tip. The other end of the hollow handle opposite the enlarged distal tip is connected to a vacuum source, such as the one readily available in most operating rooms, via flexible tubing. When the wand and the enlarged distal tip are passed over transected hair, the hair is suctioned into the hand-held device. The hand-held device includes a particulate filter to prevent the suctioned hair from entering the vacuum system, one or more internal circumferential ribs to create a turbulent flow within the handle, a reservoir to collect transected hair, and venturi apertures to regulate the suction pressure.

  • Publication number: 20140081196
    Abstract: Disclosed herein is a device for controlling the flow of a body fluid from a first tissue/organ to a second tissue/organ of a subject. The flow control device includes a main body, a first fluid channel, a second fluid channel, a detection member, and a control member. The main body defines a lumen for accommodating the body fluid flowing from the first tissue/organ into the lumen. The first fluid channel is in fluid communication with the lumen and the first tissue/organ; while the second fluid channel is in fluid communication with the lumen and the second tissue/organ. The detection member is in fluid communication with the lumen, and is operable to detect at least one parameter associated with the flow of the body fluid. The control member is operable to control the flow of the body fluid from the first tissue/organ to the second tissue/organ of the subject.

  • Patent number: 8672868
    Abstract: In a method for the automatic control of blood pumps, an optimization of the blood flow is achieved by periodic speed interventions and flow changes thereby occurring, using a formed differential variable and a control algorithm. In addition, the location of possible flow resistances on the venous or arterial side can be ascertained.

  • Patent number: 8672871
    Abstract: An implantable shunt device for draining cerebrospinal fluid from a patient's subarachnoid space includes a shunt having opposed first and second ends and a one-way valve located at the first end of the shunt. A hollow passageway extends between the tip and one-way valve such that fluid can be drained through the tip and out through the valve. The endovascular cerebrospinal fluid shunt of the present invention can be placed into a patient percutaneously via a catheter inserted into the venous system of the body through a needle hole, without the need for open surgery. The device allows for more physiologic drainage of cerebrospinal fluid since the device shunts cerebrospinal fluid into the same cerebral venous system that occurs naturally in normal people.

  • Publication number: 20140066832
    Abstract: A capillary fluid flow valve may include a chamber having a first boundary surface and a second boundary surface defined by a housing. The first and second boundary surfaces may be spaced apart by a gap sized to invoke capillary action between the surfaces. The first surface may be angled relative to the second surface. The chamber may have an inlet port, an outlet port, and an air vent port. The gap at the air vent port may be smaller than the gap at the outlet port and the gap at the outlet port may be smaller than the gap at the inlet port.

  • Publication number: 20140066833
    Abstract: A drainage implant is provided for the drainage of aqueous humor. The implant may comprise a collector, a connector and disperser. The collector and/or disperser may be self-expandable and can be held in an unexpanded condition by a delivery device. When positioned for implantation, the collector and disperser are ejected from the delivery device, whereby upon being ejected from the delivery device they can expand to a pre-defined final shape in the desired place. A delivery device for implanting the implant may have a shaft for accommodating the implant and a cutting edge that may be used to create a pocket or reservoir in the tissue where the implant device is to be implanted. Methods of implanting an implant are also disclosed.

  • Patent number: 8663150
    Abstract: A method of deploying an ocular implant into Schlemm's canal of an eye. The method includes the steps of inserting a distal end of a cannula through a cornea of the eye and into an anterior chamber of the eye, the cannula having a distal opening extending from the distal end and through a side wall; placing the distal opening of the cannula into fluid communication with Schlemm's canal; advancing the ocular implant distally through the cannula with a delivery tool engaged with the ocular implant, a proximal portion of the ocular implant engaging the delivery tool proximal to a distal portion of the delivery tool; and disengaging the ocular implant and the delivery tool when the proximal portion of the ocular implant reaches the cannula distal opening. The invention also includes a system for practicing the method.

  • Publication number: 20140052046
    Abstract: Drainage of aqueous from the anterior chamber of the eye can be facilitated by a malleable hollow clip or staple that can be formed to attach to ophthalmic tissue and provide intra-luminal flow of aqueous through the clip. In addition, the clip can be adjusted to modulate the outflow rate of aqueous, both during the initial surgical procedure as well as on a post-procedure basis. Furthermore, an instrument is described in which the forceps of the clip delivery device reside inside the lumen of hollow clip during deployment and manipulation. Features of an instrument are designed to secure the clip to the delivery forceps and prevent tissue blockage of the clip lumens. The clips may be color-matched to the underlying tissue for the purpose of camouflage and may carry pharmaceuticals.
