Abstract:
A device that, when implanted in the heart, closes the wound and complies with wall motion (i.e., expands and contracts with the myocardium).
Abstract:
A device frame includes a plurality of elongate frame members, first and second hub members substantially aligned along a longitudinal axis of the device frame, and a coupling element that couples the first hub member to the second hub member. The device frame includes a face section, a laterally facing skirt section, and an inverted section. First portions of the elongate members define the face section and extend radially from the first hub member. Second portions of the elongate members define the laterally facing skirt section and extend in a distal, axial, and helical direction along a first rotational direction from the face section. Third portions of the elongate members define the inverted section and extend in a generally proximal direction from a distal portion of the laterally facing skirt section to the second hub member along a rotational direction opposite the first rotational direction.
Abstract:
Die Erfindung betrifft ein medizinisches Implantat (1) zum Verschließen der auricula sinistra eines Patienten auf endovaskulärem Weg, das eine Korbstruktur (10) aus einer Vielzahl von Stegen (3) aufweist, die proximal über Verbindungsstege (2) mit einem Haltering (4) verbunden ist und distal von einem Kranz zusammenlaufender Stege (3) begrenzt ist, wobei das Implantat (1) aus einem selbstexpandierenden Material besteht, in einem kontrahierten Zustand die Form eines geschlitzten Rohrs hat und nach der Expansion die Korbstruktur (10) mit einem gegenüber dem Haltering (4) erweiterten Durchmesser annimmt und bei dem innerhalb der oder distal zur Korbstruktur (10) wenigstens ein oder mehrere Ankerelemente (7) angeordnet sind, die proximal direkt oder indirekt (4) mit dem Haltering verbunden sind, wobei (a) das oder die Ankerelemente (7a) distal eine Spitze (8) mit Widerhaken (9) aufweisen, mit Spitze (8) und Widerhaken (9) über die Korbstruktur (10) hinausragen und dazu bestimmt sind, mit Spitze (8) und Widerhaken (9) im Muskelgewebe der auricula sinistra verankert zu werden oder (b) das oder die Ankerelemente (7b) lateral über die Korbstruktur (10) hinausragen, nach proximal gekrümmt verlaufen und dazu bestimmt sind, sich gegen das Muskelgewebe der auricula sinistra seitlich abzustützen, oder (c) eine Kombination der Alternativen (a) und (b).
Abstract:
Devices and methods for closing access points in tissue are described. The devices include a tubular element fabricated form, for example, biologic material, a biologic tubular structure, or synthetic material. Using minimally invasive procedures, the devices and methods described herein allow implantation of the tubular element through the access point or wound such that it traverses the tissue. The tube has a sealed end which prevents leakage of fluid from, for example, the heart or a vessel upon securing the tube to the tissue.

Abstract:
Disclosed herein are implantable fistula treatment devices and methods. In some embodiments, a distal anchor for an implantable fistula treatment device may comprise a suture and multiple foldable members including at least a distal-most foldable member and a proximal-most foldable member. The distal-most foldable member may comprise a suture attachment structure. The proximal-most foldable member may be configured to couple to a surface of a body lumen at a distal opening of a fistula.
Abstract:
The invention discloses a delivery device for use in surgery on an organ in a living body. The delivery device is characterized by a proximal and a distal end interconnected by a main longitudinal axis, the distal end comprising: (a) at least one anchoring device, comprising at least one tissue anchor; and (b) at least one pivoting support in communication with the anchoring device. The anchoring device can pivot freely around the pivoting support independent of the orientation of the pivoting support with respect to the organ, such that the anchoring device can be oriented substantially parallel to and conform to the surface of the organ with which the anchoring device comes into contact.
Abstract:
In certain embodiments, a device is configured to be compressed and inserted into the distal end of an endoscope. The delivery device can be configured to deliver the delivery catheter to the site of one or more fistulas in the wall of a body cavity or lumen within a patient. The delivery catheter is configured to deliver the device to the site of the one or more fistulas. The device is configured to expand at the site of the one or more fistulas and substantially seal the fistula in one or more directions. In some embodiments, at least a portion of the device is coated with and/or constructed of biocompatible material. In some configurations, the device is configured to be implanted for an extended period of time or even permanently. In some embodiments, at least a portion of the device is constructed of biodegradable, dissolvable and/or bioabsorbable material.
Abstract:
Devices and methods for occluding or promoting fluid flow through openings are disclosed. In one exemplary embodiment an occlusion device (10) is provided having an expandable outer elongate tubular body (20), a guide member (30) extending from a distal end (20d) of the outer body, and a slide tube (40) disposed within the outer body, the proximal portions (20p,40p) of the outer body and the slide tube being fixedly mated. The slide tube is configured to slide distally within the outer tubular body when the tubular body is expanded to form wings (24a, 24b). A tether (60) can be included as part of the device and it can be used to assist in positioning and locking a location of the device in an opening. Exemplary methods for delivering devices disclosed herein are also provided.
Abstract:
A medical device (100) is provided in which one or both ends of the device encourage the formation of tissue across substantially the entire area of the respective end that is exposed to the blood flow for reducing the risk of a thrombotic embolism. The medical device includes a tubular structure (130) having at least one expanded volume portion (180) and a tapered transition portion (190). The tubular structure may be made through the braiding of a number of strands, and a first end feature (140) may be used to secure the proximal strand ends. The proximal strand ends may be secured via the proximal end of the first end feature, such that the tapered transition portion is formed over the circumferential surface of the first end feature, and only a proximal end surface (or a portion of the proximal end surface) of the first end feature is exposed to the path of flowing blood.
