Abstract: Medical devices, such as stents, and methods of making the devices, are described. In some embodiments, the invention features a medical device that includes a member having a first portion and a second portion that define an electrically conductive loop. The first portion is adapted to break or erode after expansion of the medical device, and the second portion is not adapted to break or erode after expansion of the medical device. The breaking or erosion of the first portion breaks the electrically conductive loop.

Abstract: Medical devices, such as endoprostheses, and methods of making the devices are disclosed. In some embodiments, an endoprosthesis includes a first portion having a first width, and a second portion having a second width different than the first width, wherein the first and second portions have different grain sizes.

Abstract: A tubular insert for a vessel comprises an inner stent and an outer stent. At least a portion of the inner stent is disposed within the outer stent. The outer stent has a longitudinal axis and is constructed to be free of any closed loops which are electrically conductive and which are disposed about the longitudinal axis such that the longitudinal axis passes through the closed loop. The inner stent has a longitudinal axis and is constructed so as to be free of any closed loops which are electrically conductive and which are disposed about the longitudinal axis such that the longitudinal axis passes through the closed loop. There is a substantially electrically non-conductive connection between the inner and outer stents. Desirably, a wall surface is defined by the outer and inner stents, and there are no closed, electrically conductive loops in the wall surface of the tubular insert.

Abstract: A stent comprises two serpentine bands, at least one first connector; and at least one second connector. The first and second connectors connect the two serpentine bands together. The first connector and the second each have at least a first portion of a first curvature and a second portion of a second curvature. The second portion being more flexible than the first portion. The first and second connectors are adjacent one another and the first portion of the first connector nests within the second portion of the second connector and the second portion of the second connector nests within the first portion of the first connector.

Abstract: A catheter assembly comprises a catheter having a catheter shaft with a first rotatable sheath rotatably disposed thereabout. A first guidewire housing which defines a first guidewire lumen for passage of a first guidewire therethrough is engaged to the first rotatable sheath. A first stent, which when in the reduced stent state, is disposed about at least a portion of the first rotatable sheath. A second stent, which when in the reduced stent state, is positioned adjacent to the first stent.

Abstract: A stent comprises a segment having a plurality of interconnected closed serpentine circumferential bands. Each closed serpentine circumferential band comprises a plurality of struts. Struts which are circumferentially adjacent one another are connected one to the other by a turn. Each strut has a length. The struts generally increase in length from a minimum strut length to a maximum strut length and then generally decrease in length from the maximum length to the minimum length as the circumferential band is traversed in its entirety in a clockwise direction. The maximum length struts of adjacent closed serpentine circumferential bands may be longitudinally aligned.

Abstract: A catheter assembly comprises a catheter, a rotatable sheath, a guidewire housing and a stent. The rotatable sheath is disposed about at least a portion of the catheter shaft and is rotatable thereabout. The stent is disposed about a stent receiving region of the rotatable sheath and at least a portion of the guidewire housing. The first end of the rotatable sheath extends beyond a proximal end region of the stent and the second end region of the rotatable sheath extends beyond a distal end region of the stent.

Abstract: The invention pertains to a universal bracket for mounting a fan motor assembly upon a support structure. The universal bracket consists of a plurality of low cost fabricated components and incorporates an optional dual construction whereby the components may be assembled to form a construction adapted for ceiling mounting or, in the alternative, to form a construction adapted for wall mounting. The components permit quick and easy assembly and disassembly of the universal bracket, and, in either construction, a swivel relationship exists between the assembled components permitting limited universal angular adjustment of the supported fan motor assembly.

Abstract: A unitary carton system for column supported air circulating fans wherein a plurality of fan components may be shipped in disassembled form in a single carton of concise size acceptable by package delivery services. Nested fan blade guards, a column supporting base, and a fan blade assembly are stacked within a carton and maintained in position by column structure which includes an inner carton, and the fan motor is located within a corner region. The carton cover maintains the column structure within its support, which in turn, contains the stacked components in a predetermined relationship.
