  • Patent number: 8152821
    Abstract: The present invention relates to an improved endoscopic tissue apposition device having multiple suction ports. The invention permits multiple folds of tissue to be captured in the suction ports with a single positioning of the device and attached together by a tissue securement mechanism such as a suture, staple or other form of tissue bonding. The improvement reduces the number of intubations required during an endoscopic procedure to suture tissue or join areas of tissue together. The suction ports may be arranged in a variety of configurations on the apposition device to best suit the desired resulting tissue orientation. The inventive tissue apposition device may also incorporate tissue abrasion means to activate the healing process on surfaces of tissue areas that are to be joined by operation of the device to promote a more secure attachment by permanent tissue bonding.

  • Patent number: 8146210
    Abstract: A support device or clamp connects to a soft, flexible tube, such as a medical line, to hold the tube in an open condition. The device includes a flexible body with interengaging structure that biases the body into a desired shape when in a closed position or condition. The desired shape generally matches the outer shape of the medical line. An adhesive is disposed on the support device so as to contact the secured portion of the medical line to inhibit the walls of the line from collapsing or creasing. The support device may include base structure that has an adhesive lower surface for attaching the support device to a patient's skin.

  • Patent number: 8133251
    Abstract: A blood clot filter which is collapsible toward a central longitudinal axis into a collapsed configuration for insertion into a blood vessel and which is radially expandable outwardly from the longitudinal axis to an expanded configuration for contact with the inner wall of the blood vessel at two longitudinal spaced locations. A first plurality of spaced, elongate arms, in the expanded configuration of the filter, curve outwardly away from the longitudinal axis toward the leading end of the filter to form a first filter basket and to center a hub at the trailing end of the filter within the vessel. A second plurality of spaced elongate legs angle outwardly away from the longitudinal axis toward the leading edge of the filter in the expanded configuration thereof to form a second filter basket opening toward the leading end. The ends of these legs include hooks to bend and straighten in response to withdrawal force.

  • Patent number: 8122809
    Abstract: A medical balloon with a variable diameter that is reinforced with continuous fibers woven to form a fabric with a varying number of layers and fiber densities. Portions of the balloon having a relatively smaller diameter are reinforced with a fabric having a reduced fiber density and an increased number of layers to facilitate the placement of the layers. The fabric also includes a braiding pattern that facilitates the transition from a single layer fabric to a multiple layer fabric. Also described is a manufacturing method for the braiding and layering.

  • Publication number: 20120035488
    Abstract: An electrophysiology (EP) system includes an interface for operator-interaction with the results of code executing therein. A template model can have channels positioned or repositioned thereupon by the user to define a set-up useful in rapid catheter positioning. Mapping operations can be performed without the requirement for precise catheter location determinations. A map module coordinates EP data associated with each selected channel and its associated position on the template model to provide this result, and can update the resulting map in the event that the channel or location is changed. Messaging and other dynamic features enable synchronized presentation of a myriad of EP data. Additional systems and methods are disclosed herein.

  • Patent number: 8105351
    Abstract: The present invention provides methods and devices for promoting tissue adhesion, which utilizes the healing process and scar tissue formation to bond two tissue surfaces together. A tissue injury is accomplished by destroying the mucosal layer of tissue. After the injury is initiated, the tissue is preferably held in close contact by a tissue apposition means such as a suture, staple or clip device placed adjacent to the treatment site. The tissue injury may be initiated by electrical/radiofrequency energy or chemical or mechanical means integrated with the tissue apposition device or delivered by a separate instrument such as an electrocautery catheter through an endoscope. As scar tissue created by the injury forms, the tissue surfaces become bonded together in a permanent union.

  • Patent number: 8092484
    Abstract: A removable blood clot filter includes a number of locator members and anchor members, and a bio-resorbable structure that causes locator members and/or anchor members to deploy to an initial configuration which changes when the bio-resorbable structure is resorbed. The bio-resorbable structure causes the filter locator members and/or anchor members to press against the vessel wall sufficient to locate and anchor the filter upo delivery. After the bio-resorbable structure is resorbed, the locator members and/or anchor members change shape to apply less pressure against the vessel wall. The bio-resorbable structure may be activated by exposure to radiation so that actuation of the locator members and/or anchor members can be enabled or initiated by a clinician.
