摘要:
Devices, systems and methods are described herein for sealing openings in an anatomical wall. A sealing system includes an elongate tubular support for delivery to an anatomical opening to be sealed, a cover of bio-compatible material covering a distal portion of the tubular support, and an anchor assembly, the anchor assembly being designed to secure the cover material to the opening. The anchor assembly can include a plurality of distal anchors and a plurality of proximal anchors, a button, ring or donut, and/or a C-clip. In some embodiments, the system further comprises a closure member for closing off an end of the cover material after removal of the tubular support.

Die vorliegende Erfindung betrifft einen medizinischen Führungskatheter (100) zur Verwendung beim Implantieren eines Mitralklappenimplantats 600) oder zum Reparieren eines Herzdefekts oder einer Mitralklappe (719), wobei der Führungskatheter (100) aufweist: einen distalen Endbereich (310), welcher ein distales Ende des Führungskatheters (100) umfasst, und einen proximalen Endbereich (105), welcher ein proximales Ende des Führungskatheters (100) umfasst; einen hohl ausgestalteten Führungsabschnitt (107); wobei der Führungsabschnitt (107) einen geraden Abschnitt (109) und einen gekrümmten Abschnitt (111) aufweist; und wobei der gekrümmte Abschnitt (111) im distalen Endbereich (103) liegt oder das distale Ende bildet; wobei der gekrümmte Abschnitt (111) distal zum geraden Abschnitt (109) angeordnet ist.
摘要:
A device for inserting a medical apparatus into a living body includes a handle and an elongated sheath extending from the handle to a distal end configured for insertion to a target location in the living body in combination with a clasp positioned within a distal portion of the elongated sheath and configured to temporarily attach to an endoscopic device and a spring retention mechanism movable from a first resting configuration maintaining a first closed position of the clasp to a second compressed configuration moving the clasp to an open position. A withdrawal mechanism is movable from a first resting configuration in which the distal end of the elongated sheath extends distally over a distal end of the endoscopic device to a second retracted configuration in which the distal end of the elongated sheath is moved proximally of the distal end of the endoscopic device.

With an endoscope (1) including an inserted portion (2) that is inserted into the body of a patient, securing means (3) for securing the inserted portion (2) to tissue (A) inside the body, the securing means (3) being provided at least at a distal-end portion of the inserted portion (2), an observation optical system (4) that is provided at the inserted portion (2) and that acquires an image of the tissue (A), and observation-distance adjusting means (5) for adjusting the distance between the observation optical system (4) and a surface of the tissue(A), it is possible to attain a stable field of view without having to stop the pulsation or the like of the heart or other tissue.
摘要:
A device and method for closure, of a body channel of a patient, such as a patent foramen ovale. The device includes a frame member having a collapsed condition and an expanded condition. The frame member is sized and arranged to be percutaneously insertable into an area of the foramen ovale when in the collapsed condition, and to substantially span the foramen ovale when in the expanded condition. A promoter carried by the frame member, such as a clot- promoting composition and/or a tissue growth-promoting composition, is capable of promoting biological formation with the tissue bordering the foramen ovale to effect a closure of the foramen ovale.
