摘要： A stent loading and deployment device includes an outer elongate tubular member having opposed proximal and distal ends and an inner elongate tubular member having opposed proximal and distal ends and slidably disposed within the outer tubular member. When the distal ends of the outer tubular member and the inner tubular member are axially aligned, a stent deployment region is defined there in between. The device further includes a stent loading member having opposed proximal and distal ends and slidably disposed between the outer tubular member and the inner tubular member. The distal end of the stent loading member is slidable to a distal position past the distal end of the outer tubular member for receiving a stent and is further slidable toward the proximal end of the outer tubular member to a location past the stent deployment region for disengagement of a stent from the stent loading member.

摘要： Medical devices and methods are disclosed. An example method for accessing a body lumen may include providing a catheter system. The catheter system may include a catheter shaft having a lumen defined therein and an outer wall surface having a channel formed therein. A first guidewire may be disposed in the channel and a second guidewire may be disposed in the lumen. The method may also include advancing the catheter system through a body lumen to a location where the body lumen splits into a first section and a second section, advancing the first guidewire into the first section, and advancing the second guidewire into the second section, and advancing the catheter shaft along the second guidewire and into the second section. Advancing the catheter shaft along the second guidewire and into the second section may remove at least a portion of the first guidewire from the channel.

摘要： The reconstrainment band includes a hollow generally tubular shaped band having proximal and distal ends and having an exterior surface for engaging a stent and an interior surface for engaging a delivery tube. The exterior surface has at least one fin projecting therefrom along the longitudinal axis of the band. The fin has at least one obtusely shaped surface relative to the longitudinal axis and facing one of the ends. The reconstrainment band is included in a delivery device for intraluminally positioning and deploying a radially distensible stent. Reconstrainment of a partially deployed stent is provided by the delivery device.

摘要： An endoscope may include a shaft having a longitudinal axis, a first image sensor facing a distal direction, and a second image sensor facing a lateral direction. The endoscope may further include a tubular member having a lumen, the lumen having a distal-end opening and defining a longitudinal axis through a center of the lumen. The tubular member may be movable between a first configuration and a second configuration. In the first configuration of the tubular member, the longitudinal axis of the lumen may be parallel to the longitudinal axis of the shaft. In the second configuration of the tubular member, the longitudinal axis of the lumen may extend through a lateral opening in a wall of the shaft.
