Abstract:
Stent-grafts for treating thoracic aortic aneurysms and abdominal aortic aneurysms include graft portions having inflatable channels and graft extensions. The graft extensions include an undulating wire stent and porous, but substantially fluid impermeable, polytetrafluoroethylene (PTFE) graft materials.
Abstract:
Method for installation of a pipe based system (pipe system) comprising pipe lengths and coupling components, distinguished in that the method comprises the steps: to pre-assemble the pipeline system loosely by assembling pipe lengths and coupling components by inserting pipe lengths into coupling parts, the coupling parts are adapted so as to hold the pipe length in place and in orientation whilst the axial pipe length position in the coupling component easily can be adjusted, and conduct optional sufficient clamping or attachments to the surrounding walls, ceilings or floors, so that the pipe system is self-supporting in the intended position and such that the assemblage of the components easily can be adjusted by a technician, to adjust the components of the pipeline system into the intended position, so that the pipeline system is basically without any inherent tensions, optionally to attach or clamp the pipeline system further onto to the surrounding walls, ceilings or floors, and to permanently join the pipe lengths and coupling components.
Abstract:
A medical device includes a polymer scaffold crimped to a catheter having an expansion balloon. The scaffold is crimped to the catheter by a multi-step process for increasing scaffold-catheter yield following a crimping sequence. Damage reduction during a crimping sequence includes modifying blades of a crimper, adopting a multi-step crimping sequence, and inflating a supporting balloon to support the scaffold during crimping.
Abstract:
A medical device includes a polymer scaffold crimped to a catheter having an expansion balloon. The scaffold is crimped to the balloon by a process that includes heating the scaffold to a temperature below the polymer's glass transition temperature to improve scaffold retention without adversely affecting the mechanical characteristics of the scaffold when later deployed to support a body lumen. Additionally, before crimping begins the scaffold is placed on a support by an alignment carriage and deionized to remove any static charge buildup on the scaffold before placing the scaffold within the crimping mechanism.
Abstract:
A medical device includes a polymer scaffold crimped to a catheter having an expansion balloon. The scaffold, after being deployed by the balloon, provides a crush recovery of about 90% after the diameter of the scaffold has been pinched or crushed by 50%. The scaffold has a pattern including an asymmetric closed cell connecting links connecting the closed cells.
Abstract:
A method of crimping a stent on a balloon of a catheter assembly is provided. A polymeric stent is disposed over a balloon in an inflated configuration. The stent is crimped over the inflated balloon to a reduced crimped configuration so that the stent is secured onto the balloon. The balloon wall membrane is wedged or pinched between the strut elements of the stent for increasing the retention of the stent on the balloon.
Abstract:
Die Erfindung betrifft zum Einen ein Verfahren zum Verpressen eines Pressfittings (3) mit einem in den Pressfitting (3) eingeschobenen Rohr (2) mittels eines Presswerkzeuges (1), wobei der Pressfitting (3) einen umlaufenden Wulst (31) aufweist, in welcher ein O-Dichtring (32) eingelegt ist, wobei das Rohr (2) innerhalb des Pressf ittings (3) endet und innerhalb des Wulstes (31) eine erste Verpressung durchgeführt wird, wobei weiter rohreinsteckseitig des Pressf ittings (3) mit Abstand zu dem Wulst eine weitere Verpressung durchgeführt wird, die zu einer abzugshemmenden, gleichsinnig verlaufenden Konizität von Pressfitting (3) und Rohr (2) führt. Zum Weiteren betrifft die Erfindung ein zur Durchführung des Verfahrens geeignetes Presswerkzeug (1).
Abstract:
A method of assembling a metal shore post of a concrete forming assembly is disclosed. An outer telescoping tube is provided that has a main section with a first inside diameter and top portion with a section having a second inside diameter reduced relative to the first inside diameter of the outer tube. An inner telescoping tube is inserted for telescopic movement inside the outer tube. After assembly, a pair of pistons are inserted through access holes in the outer tube to provide a crushing force to the inner tube deforming it to create a region of increased diameter that is greater than that of the reduced diameter section but not so large as to prevent telescopic movement of the inner tube inside the outer tube. The increased dimension region thereby prevents accidental separation of the inner tube from the assembly.
Abstract:
A coiled tubing connector for connecting tools together when they are inserted into a well bore. The connector includes a disposable element that may be severed along with the connected portion of the coiled tubing. This provides for quick disconnect and reuse of the remainder of the connector.
Abstract:
A compression connector assembly for securing a cable has a bushing insert and a gripping sleeve. The bushing insert includes a tubular bore, an exterior surface, a conductor receiving end, and a conductor engagement end. The gripping sleeve has an inner recess and an outer surface, and is adjacent to the conductor engagement end. The tubular bore and the inner recess are substantially coaxial, defining a cable securing passageway.
