摘要:
A medical implant delivery system is described. The system can be used to deliver a variety of implants including stents and/or stent grafts. The delivery system retains the implant during delivery and detaches the implant at a target location.
摘要:
An implant delivery system is described. The implant delivery system utilizes an implant, implant wire, delivery sheath, and a torque device. The torque device may include a cutting element to slit the delivery sheath and a clamp device to fix the position of the implant delivery wire.

The present disclosure relates to stents and methods of delivering and deploying the same. The stents include fasteners about their periphery and when the stent is radially compressed, the fasteners come into alignment such that a device may be placed through openings in the fasteners to hold the stent in the radially compressed configuration. When the device is removed from the openings, the stent may expand.
摘要:
A stent delivery system is provided that includes a self-expanding stent with a longitudinal length and a plurality of individual suture loops spaced along the longitudinal length of the stent, wherein the stent is compressed by the plurality of individual suture loops. The stent delivery system also includes a longitudinal pull member that secures the plurality of individual suture loops about the stent, wherein the plurality of individual suture loops are configured to separate from about the stent when the longitudinal pull wire is removed.
摘要:
An assembly of a retrieving element and a retrievable device of which one is a helical spring having an outer part of a winding which extends away from a main portion of the spring and thus is able to engage a thread of the other of the retrieving element and a retrievable device. The other of the retrieving element and a retrievable device may have an outer or an inner thread. The assembly may be used for retrieving devices temporarily positioned in a blood vessel of a person.
摘要:
A reconfigurable delivery system is disclosed having a multi-lumen delivery catheter configuration that permits the delivery and staged release of a self-expanding main vessel stent-graft and a delivery sheath configuration that permits the introduction of various medical devices for the delivery and implantation of various branch vessel stent-grafts that are to be mated with the main vessel stent-graft. A method is disclosed wherein the delivery system is first used in the multi-lumen delivery catheter configuration to deliver and release a main vessel stent-graft that is configured for placement in the abdominal aorta for treatment of short-neck infrarenal, juxtarenal, and/or suprarenal aneurysms and then used in the delivery sheath configuration to facilitate the delivery of branch vessel stent-grafts that are configured to extend from the main vessel stent-graft into a respective renal artery.
摘要:
An aneurysm occlusion system includes a device positionable within a cerebral blood vessel covering a neck of an aneurysm on the blood vessel. The device includes an expandable tubular element having a lumen surrounded by a sidewall including a plurality of gaps. When expanded, the tubular element includes longitudinal standards arrayed helically in a proximal to distal direction. The standards support struts and the gaps are defined between adjacent struts and are sufficiently large to permit delivery of embolic coils or other embolic materials therethrough.
摘要:
A stent-graft delivery system (200) includes an elongate shaft (212), a tip capture spindle (224) disposed over the shaft, and a distal tip assembly (228) coupled to the distal end of the shaft. At least one component of the delivery system constrains a stent of the stent-graft (230) engaged with the tip capture spindle during delivery and partial- deployment of the stent-graft, and the at least one component is in a threaded relationship with the distal tip assembly. To fully deploy the stent-graft, the elongate shaft, having the distal tip assembly coupled thereto, is rotated to result in longitudinal movement of the tip capture spindle and/or a relatively short sleeve that extends over the tip capture spindle to the distal tip assembly and thereby release the stent from the tip capture spindle.
摘要:
Die Erfindung betrifft eine Thrombektomievorrichtung mit einer im Wesentlichen zylindrischen Stentstruktur (1), die eine Vielzahl von Maschen (3, 4) aufweist sowie zwei Verbinder (5, 5'), die an verschiedenen Maschen (3) am proximalen Ende der Stentstruktur (1) angeordnet sind und einem Führungsdraht (2), der ein Kopplungselement (11) aufweist, an das die Verbinder (5, 5') angekoppelt sind sowie einem Schlitz (7), der sich wendeiförmig über die Mantelfläche (8) der Stentstruktur (1) erstreckt und einem Spannbügel (9) der am proximalen Ende den Schlitz (7) überspannt.
