  • Patent number: 11007061
    Abstract: Devices and methods for treating patients with functional tricuspid regurgitation (TR) who are unsuitable for surgery include an interoperative, adjustable-size coapting element on a catheter which may be implanted within the left or right side of the heart and extends upward into the vasculature and out of the body. The radial diameter of the coapting element can be modulated in tandem with electrocardiographic imaging to reduce valve regurgitation. One system has an elongated catheter and an expandable coapting element mounted to a distal end with an auxetic structure connected to opposite end caps. A tensioning mechanism controlled from a proximal end of the catheter is configured to pull apart the two end caps and thus elongate and radially expand the auxetic structure. Other forms of the coapting element are disclosed, as well as a kink-resistant catheter sheath having a triangular cross-section.

  • Patent number: 10980667
    Abstract: Devices can be implanted in an eye to treat a dry eye condition. The devices include a body defining a lumen and having first and second ends and external and lumenal surfaces. The body has a length sufficient to provide fluid communication between the anterior chamber and tear film of the eye through the lumen when the device is implanted in the sclera. In some embodiments, the device is filterless. In some embodiments, a filter is included. The dry eye treatment devices provided herein prevent bacterial ingress, provide outflow resistance to retain a normal intraocular pressure, and provide moisture (e.g., aqueous humor) to an otherwise dry eye. Methods of treating a dry eye condition wherein the device is implanted in the sclera of an afflicted eye are also described.

  • Patent number: 10123803
    Abstract: Systems, methods, and devices for the treatment of acute ischemic stroke that provide immediate blood flow restoration to a vessel occluded by a clot and, after reestablishing blood flow, address the clot itself. Immediate blood flow restoration advantageously can facilitate natural lysis of the clot and also can reduce or obviate the concern for distal embolization due to fragmentation of the clot. Several embodiments of the invention provide for progressive, or modular, treatment based upon the nature of the clot. For example, the progressive treatment can include immediate restoration of blood flow, in-situ clot management, and/or clot removal depending on the particular circumstances of the treatment. The in-situ clot management can include, for example, lysis, maceration, and/or removal.

    Abstract: A percutaneous transluminal angioplasty device includes an embolic filter mounted to the catheter shaft at a location distal to the angioplasty balloon. Thus the filter is downstream from the blockage and is properly positioned to capture embolic particles that may be set loose into the blood stream as the angioplasty procedure is performed. The embolic filter is normally collapsed against the catheter shaft to facilitate introduction and withdrawal of the device to and from the operative site. Once the angioplasty balloon is properly positioned, however, means operatively associated with the embolic filter are actuated to erect the filter to position a filter mesh across the lumen of the vessel.

    Abstract: The invention relates generally to medical devices and methods for the treatment of ocular disorders. One method provides an implant having an inlet portion with a first anchor and an outlet portion with a second anchor. The implant is implanted in tissue of an eye such the implant conducts fluid from an anterior chamber of the eye to a physiological outflow pathway of the eye. The implanting involves positioning the first anchor adjacent eye tissue, positioning the second anchor within the physiological outflow pathway, and deploying the second anchor such that the second anchor secures the implant within the physiological outflow pathway and a distal end of the second anchor is positioned further into the physiological outflow pathway than an outlet of the outlet portion.

  • Patent number: 8241250
    Abstract: The present invention provides a gastrostomy or jejunal device for extended insertion into an abdomen of a patient. The device includes a catheter and a coaxial sheath that surrounds the catheter. The sheath includes a plurality of curved or oblique slots through the sheath materials that form a plurality of arms. A rotatable actuation device is provided to twist the sheath along its longitudinal axis which places the arms in compression and causes them to buckle radially outward beyond the circumference of the remainder of the sheath when the actuation device is rotated with respect to the remainder of the device.

  • Patent number: 8211085
    Abstract: Therapeutic device intended for the selective cytoreductive treatment of an obstruction in a natural lumen or passage of the human or animal body, said lumen being obstructed by the effect of a local cell proliferation, said device comprising a tubular element, in particular of cylindrical shape, intended to be placed in said natural lumen and sufficiently flexible to conform to said natural lumen, but sufficiently rigid to maintain an artificial channel in said lumen. The tubular element supports lengthwise a medicinal sleeve which is intended to come into line with, and into contact with, the obstruction once the natural lumen has been intubated, and is designed to deliver locally, at least in its outer surface portion, at least one therapeutic agent which is cytoreductive, in particular cytotoxic, through contact with the cells under whose effect said lumen is obstructed.

  • Patent number: 8206332
    Abstract: A catheter is adapted to exchange heat with a body fluid, such as blood, flowing in a body conduit, such as a blood vessel. The catheter includes a shaft with a heat exchange region disposed at its distal end. This region may include hollow fibers which are adapted to receive a remotely cooled heat exchange fluid preferably flowing in a direction counter to that of the body fluid. The hollow fibers enhance the surface area of contact, as well as the mixing of both the heat exchange fluid and the body fluid. The catheter can be positioned to produce hypothermia in a selective area of the body or alternatively positioned to systemically cool the entire body system.

  • Patent number: 8105335
    Abstract: A manually manipulatable tool for removing a fecal impaction, the tool is adapted for insertion into a patient's rectum to engage and penetrate the impaction. The tool is fitted with flexible, arcuately configured elements collapsible at least partially during insertion into the rectum and penetration of the fecal impaction, withdrawal of the tool deploying the elements to exert traction on the impaction thus facilitating withdrawal of at least portions of the impaction. A body member of the tool is preferably elongated and can optionally be provided with a longitudinally extending lumen for introduction of an enema solution concurrently with or independently of impaction removal.

  • Patent number: 8048056
    Abstract: A gastrostomy device includes a tubular portion and an internal bolster having a radial wing secured to the tubular portion. The internal bolster is flexible and permits elastic deformation between a first orientation with the wing wrapped into a generally cylindrical configuration and a second orientation with the wing unfurled. A constraining member encases the internal bolster to retain the internal bolster in the first orientation and to cover at least a major portion of the wrapped wing. Removal of the casing permits the internal bolster to move from the first orientation to the second orientation. The internal bolster may be deployed by a ripcord, freeing the internal bolster into the patient' stomach and deploying the internal bolster to the second orientation. Alternatively, the internal bolster may be deployed by the constraining member being dissolved by the patient's bodily fluids located inside the patient's stomach.

  • Patent number: 8021332
    Abstract: An agent delivery catheter which has a support member comprising at least one articulating arm having an end fixedly secured relative to the shaft and having an anchor end section opposite to the fixed end. The articulating arm is biased to pivot at the fixed end away from the shaft, to transform from a low profile configuration to a high profile configuration in which the arm extends laterally away from the shaft and the anchor end section contacts the patient's body lumen wall, to support the shaft in the body lumen during delivery of an agent, for example by injection from a needle extended from the catheter into the wall of the body lumen.
