    Abstract: Catheter systems configured for emergency blood-vessel occlusion and associated devices, systems, and methods are disclosed herein. A catheter system configured in accordance with a particular embodiment includes a catheter, a sheath, and an extracorporeal proximity sensor. The catheter includes an elongated body having a tip, a sealing portion, and a main shaft proximal to the sealing portion. The tip is configured to dilate a blood vessel ahead of the distal end portion of the sheath as the catheter and the sheath are advanced together through the blood vessel. The distal end portion of the sheath is configured to fit snugly around the sealing portion. The catheter further includes a balloon and a proximity-sensor target less than about 10 centimeters from the balloon. The proximity sensor is configured to receive a signal from the proximity-sensor target to aid in positioning the balloon without fluoroscopic guidance.

  • Patent number: 10376267
    Abstract: A vascular occlusion device includes a braided filament mesh structure defining a longitudinal axis. The mesh structure has a relaxed configuration in which it has an axial array of radially-extending occlusion regions, each of which has a proximal side and a distal side meeting at a peripheral edge, the sides of each occlusion region forming a first angle relative to the longitudinal axis. Each occlusion region is axially separated from the adjacent occlusion region by a reduced-diameter connecting region. The mesh structure is radially compressible to a compressed state in which it is deployed intravascularly to a target site through a catheter. Upon deployment, the device radially expands to a constrained configuration in which the peripheral edges of the occlusion regions engage the vascular wall, and the sides of the occlusion regions form a second angle relative to the longitudinal axis that is smaller than the first angle.

    Abstract: An adjustable shape abscess irrigation device includes a first tube that is slidably associated with a second tube. The irrigation device includes a retainer that defines a variable shape diameter. The diameter of the retainer is selectively adjustable by the relative positioning of the first tube and the second tube such that, once placed relative to an abscess, the shape of the device can be manipulated to allow desired drainage of irrigation and abscess fluids beyond the confines of the abscess. Upon adequate drainage of the abscess, the cross-section shape of the retainer can be reduced to facilitate more comfortable and less detrimental removal of the device from the patient. Preferably, the irrigation device is formed via one or multi-shot injection molding and is formed of more than material.

    Abstract: A structure that can be used to provide an anchor in or adjacent to a patient's soft body tissue (rather than bone) includes an annular array of flexible members that extend between two axially spaced but aligned tubular members. The space between the tubular members can be selectively changed to affect the amount by which portions of the flexible members between the tubular member project radially outward relative to the tubular members. When the flexible members project radially out, the structure resists axial movement relative to adjacent tissue and therefore acts as an anchor. When the flexible members do not project radially out, they permit axial movement of the structure through adjacent tissue.

  • Patent number: 8377004
    Abstract: A drug delivery pump drive which uses a linear piezoelectric motor to advance a syringe piston to deliver a liquid drug and a method thereof are disclosed. The pump drive, provided in a drug delivery pump, provides silent operation and very low energy consumption compared to electric motor-based drives. The small size of the motor helps also to reduce overall size of the pump drive and the resulting drug deliver pump.

  • Patent number: 8343028
    Abstract: A device and method for creating a connection with the left ventricle of a heart are provided. A seal member capable of moving between a folded position and an open position is attached to the end of a conduit. An introducer capable of moving between a first and second position allows for the expansion of the seal member into an open position. A clamp component is positioned outside of the heart to provide an axial clamping force with the wall of the heart so that a seal is created between the seal member and the wall of the heart.

  • Patent number: 8337445
    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: 8231651
    Abstract: A guided filter system for temporary placement of a filter in an artery or vein is disclosed. The system includes a guidewire slideable through a wire guide included in a distal region of a support wire. The support wire has an expandable filter, which is operable between a collapsed or enlarged condition. A variety of endovascular devices, including angioplasty, atherectomy, and stent-deployment catheters, are insertable over the guidewire and/or the support wire. Methods of using the guided filter system to direct and exchange endovascular devices to a region of interest, and to entrap and remove embolic material from the vessel are also disclosed.

  • 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: 8075511
    Abstract: Systems and methods for treating ocular disorders are disclosed. One system has an implant and a delivery device. The implant has inlet and outlet portions, a lumen extending therebetween and communicating with inlet and outlet ports. The implant is sized so that in use aqueous humor flows from an anterior chamber of an eye through the implant and into a uveal scleral outflow path of the eye. The delivery device is configured to advance the implant from within the anterior chamber, with the outlet portion leading the inlet portion, to a location where the outlet and inlet ports respectively communicate with the uveal scleral outflow path and the anterior chamber. One method involves advancing an implant from within the anterior chamber, and draining fluid from therein such that fluid flows into an implant inlet port and out through an implant outlet port and into the uveal scleral outflow path.
