摘要： A stent is provided having a plurality of intersecting elongated members arranged to form a plurality of cells, the plurality of cells defining an elongated tube with a lumen running therethrough. The elongated tube has first, second, and third sections, the first section having a substantially first diameter and the third section having a substantially constant second diameter that is larger than the substantially constant first diameter of the first section, wherein the diameter of the second section transitions from the first diameter to the second diameter. Each of the plurality of cells within the first section have a pitch that is tighter than each of the plurality of cells within the second and third sections. In the second section, the plurality of intersecting elongated members includes a plurality of pairs of elongated members, wherein each pair of elongated members includes two adjacent elongated members twisted axially around each other.

摘要： An endoluminal prosthesis system for a branched body lumen comprises a branch vessel prosthesis. The branch vessel prosthesis is deployable within a branch vessel body lumen and comprises a stent having a generally tubular body portion, a flareable proximal end portion, and a coupling portion disposed intermediate the body portion and the flareable portion. The coupling portion is more crush-resistant than the body portion. The flareable proximal end may be disposed within a fenestrated stent graft wit with coupling portion disposed in the fenestration of the fenestrated stent graft.

摘要： A scope system is provided including an elongate tube with a distal portion and a lumen extending therethrough. The scope system also includes at least one accessory channel including a tubular structure with an accessory lumen extending therethrough, the at least one accessory channel movably disposed at least partially within the lumen of the elongate tube. The at least one accessory channel includes a distal section and a forward-viewing configuration and a side-viewing configuration. In the forward-viewing configuration, the distal section of the at least one accessory channel is substantially parallel to the distal portion of the elongate tube and in the side-viewing configuration, the distal section of the at least one accessory channel is arced at a radius greater than a radius of the distal portion of the elongate tube.

摘要： Examples of prostheses are provided having an internal branch. A tubular graft body of the prosthesis defines a main lumen extending between an inflow end and an outflow end of the graft body. A stent structure is coupled along the graft body. A trough is at least partially defined by a trough wall extending into the main lumen from a sidewall of the graft body. A side branch defines a branch lumen and extends from the trough within the main lumen towards one of the inflow or outflow ends of the graft body. A branch lumen facing surface of the trough wall is a continuous surface with an outer surface of the sidewall of the graft body. A boundary of the trough may be configured to provide a smooth transition surface between the trough and the sidewall.

摘要： Medical device loading apparatuses, systems, methods and kits are described. A loading apparatus comprises a main body having a proximal end defining a proximal opening, a distal end defining a distal opening, and a passageway extending between the proximal and distal openings. The passageway defines a proximal chamber having a first inner diameter, a distal chamber having a second inner diameter, and a transition chamber disposed between the proximal and distal chambers. The transition chamber has an inner diameter that transitions from the larger second inner diameter to the smaller first inner diameter. The main body has a separable connection that divides the main body between proximal and distal portions when disrupted. An expandable intraluminal medical device can be loaded into a delivery catheter using the loading apparatus by placing the device into the passageway such that it is in a radially-expanded configuration; pulling the device along an axial path through the loading apparatus such that the device transitions from the radially-expanded configuration to a radially-compressed configuration; and pushing the radially-compressed device along the axial path into the delivery catheter.

摘要： An implantable graft may include a main section having walls formed with a woven fabric, the main section having a main lumen extending therethrough. The implantable graft may also include a bifurcated section having walls formed with the woven fabric, where the bifurcated section extends from main section, where the bifurcated section includes a first branch and a second branch, and where the first branch and the second branch each include a branch lumen in fluid communication with the main lumen. At least one branch of the bifurcated section may include a branch taper formed by a seam connecting a first woven layer and a second woven layer. A seam extension may extend outwardly along the seam of the branch taper, the seam extension being a single-layer woven structure.

摘要： A control for an endoscope includes a housing defining an interior volume. A lever external to the housing extends through the housing into the interior volume. A gear system positioned in the interior volume is operatively coupled to the lever. The gear system includes a first quadrant and a second quadrant each configured to pivot about a corresponding axis to deflect a flexible distal tip portion of the endoscope in a corresponding direction.

摘要： Storage devices, loading devices, delivery systems, kits, and associated methods for implantable medical devices are described. An example embodiment of a storage device includes a storage member, a first cap, and a second cap. The storage member has a first end, a second end, and a main body that defines a first opening, a second opening, a passageway, a separating wall, and a plurality of holes. The passageway has a first portion and a second portion. The first portion extends from the first end of the storage member to the separating wall and the second portion extends from the second end of the storage member to the separating wall. Each hole of the plurality of holes extends through the separating wall and provides access between the first portion and the second portion. Each of the first and second caps is releasably attached to the storage member.
