  • Publication number: 20180289388
    Abstract: A transseptal needle or punch is described wherein the distal end of the transseptal needle is able to articulate laterally out of the longitudinal axis of the steerable transseptal needle. The transseptal needle includes a blunted distal end configuration that is minimally traumatic. Under control by the user or a computer, the transseptal needle can be articulated to generate various curves with high bending force. The transseptal needle is configured for use with an introducer which can also include side windows.

  • Patent number: 9827404
    Abstract: Disclosed is an expandable transluminal sheath, for introduction into the body while in a first, low cross-sectional area configuration, and subsequent expansion of at least a part of the distal end of the sheath to a second, enlarged cross-sectional configuration. The sheath is configured for use in the vascular system and has utility in the performance of procedures in the left atrium. The access route is through the inferior vena cava to the right atrium, where a trans-septal puncture, followed by advancement of the catheter is completed. The distal end of the sheath is maintained in the first, low cross-sectional configuration during advancement to the right atrium and through the atrial septum into the left atrium. The distal end of the sheath is subsequently expanded using a radial dilatation device.

  • Publication number: 20170259041
    Abstract: This invention is a transvascularly placed steerable guidewire, further including internal steerability and the ability to articulate in a direction at right angles to its longitudinal axis at or near its distal end. The steerable guidewire is generally fabricated from stainless steel and includes an outer tube, an inner tube, hub structures, and a distal articulating region. The steerable guidewire can be advanced through a body lumen in its straight configuration and then be selectively articulated or curved to permit negotiation of tortuous curvature. The steerable guidewire hub can be removed to permit advancement of catheters over its proximal end followed by re-attachment of the hub to permit deflection of the distal end of the steerable guidewire. Removal of the hub can result in a limp guidewire or maintenance of a forced curvature of the distal end of the guidewire.

  • Patent number: 9440054
    Abstract: Disclosed is an expandable transluminal sheath, for introduction into the body while in a first, small cross-sectional area configuration, and subsequent expansion of at least a part of the distal end of the sheath to a second, enlarged cross-sectional configuration. The sheath is configured for use in the vascular system and has utility in the introduction and removal of implant delivery catheters. The access route is through the ventricular myocardium, more specifically at the left ventricular apex, into the aortic root. The distal end of the sheath is maintained in the first, low cross-sectional configuration during advancement to the arteries into the aorta. The distal end of the sheath is subsequently expanded using a radial dilatation device, which is removed prior to the introduction of implant delivery catheters. In an exemplary application, the sheath includes a supported proximal end, a supported distal end, and a collapsible center section.

  • Patent number: 9393041
    Abstract: An expandable medical sheath is configured to be introduced into a body in a first, low cross-sectional area configuration, and expanded to a second, enlarged cross-sectional configuration. The sheath is maintained in the first, low cross-sectional configuration by structures or elements within the sheath wall that maintain a collapsed shape. Upon expansion with a dilator, the sheath maintains a second, enlarged cross-sectional configuration by elements or structures within the sheath tubing wall that resist re-collapse. The sheath includes a nose cone or tapered fairing to deflect tissue from entering the collapsed distal end of the sheath during introduction. The fairing collapses following expansion and subsequent deflation of the dilator, thus allowing the tapered fairing to be withdrawn proximally through the central lumen of the sheath. In one application, the sheath is utilized to provide access for a diagnostic or therapeutic procedure such as percutaneous nephrostomy or urinary bladder access.

  • Patent number: 9387314
    Abstract: Disclosed is an expandable transluminal sheath, for introduction into the body while in a first, collapsed cross-sectional configuration, subsequent expansion of at least a part of the distal end of the sheath to a second, enlarged cross-sectional configuration, and subsequent removal in a third, collapsed cross-sectional configuration. The sheath is configured for use in the vascular system and has utility in the introduction and removal of implant delivery catheters. The access route is through the femoral arteries and the iliac arteries into the aorta. The distal end of the sheath is maintained in the first, collapsed cross-sectional configuration during advancement to the arteries into the aorta. The distal end of the sheath is then expanded using a radial dilatation device, which is removed prior to the introduction of implant delivery catheters. The distal end of the sheath is subsequently reduced to a diametrically small size for removal.

  • Patent number: 9339266
    Abstract: Devices and methods are disclosed for protecting individuals from the sharp ends of medical objects following use on a patient. Such sharp objects include hypodermic needles, scalpel blades, cannulae, trocars, and the like. The invention utilizes a disposable protective cover for the used sharp. The protective cover is designed to surround and embed the sharp in a permanent cover that is blunt and will not permit further puncture or cutting with the sharp. In an embodiment, the protective cover also absorbs any fluids on or in the used sharp and prevents any fluids from escaping the protective cover. The sharp cover is configured to irreversibly lock, once closed. A refillable or replaceable dispenser dispenses the protective covers at points of use. A disposable receptacle receives the used sharp embedded in the protective cover. When the receptacle is full, the entire receptacle may be discarded in a medical waste container.

  • Publication number: 20150359549
    Abstract: A catheter system can be used to remove obstructions, deliver implantable devices or substances, and/or restore flow through body lumens. The system can include an outer shaft having a lumen, sidewall, and a longitudinal window in the sidewall, an inner shaft disposed within the lumen, and an expandable member having a first end coupled to the outer shaft and a second end coupled to the inner shaft through the window. The expandable member can be positioned adjacent to a target region while in the collapsed configuration. The expandable member can be expanded to an expanded configuration by relative movement of the outer shaft and the inner shaft.
