摘要： A method of treating a lesion in a gastrointestinal tract and an injectate system are provided. The method includes injecting a crosslinkable gel into a first tissue layer, the crosslinkable gel increasing a volume of the first tissue layer. The method also includes providing a crosslinker and resecting a portion of a first tissue layer having the increased volume away from a second tissue layer creating an exposed region in a remaining portion of the first layer and leaving a portion of the gel covering at least a portion of the exposed region. The injectate system includes a crosslinkable gel and a crosslinker where the crosslinkable gel and the crosslinker form a crosslinked gel having a compressive modulus of about 10-500 kPa.

摘要： A balloon catheter is provided that may be used to dilate hardened regions of a stenosis. The balloon catheter is provided with one or more dilation elements that extend along a surface of a balloon. Each dilation element is monolithically connected to an outer surface of the balloon by a connector. The connector is sufficiently sized and designed to undergo stress-induced plastic deformation incurred during blow molding so that a significant portion of each of the dilation elements does not become absorbed into the wall of the final blow molded balloon, thereby maintaining the structural integrity of each of the dilation elements. The dilation element has a flattened outer surface along at least proximal and distal neck portions of the balloon.

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 swaged braided catheter for use in various medical procedures is provided. The swaged braided catheter includes a tubular braid formed from a plurality of braided wire members. A plurality of intersections is formed by the braided wire members. The intersections are compressed defining a plurality of flattened regions along the tubular braid. The intersections have a first thickness before being compressed and a reduced second thickness after being compressed. The flattened regions with the reduced second thickness provide the swaged braided catheter with a reduced cross-sectional profile, and reduced catheter recoil.

摘要： Implantable frames for use in body passages are provided herein. The implantable frames can include a plurality of hoop members joined by a plurality of longitudinal connecting members to form a tubular frame defining a cylindrical lumen. The plurality of longitudinal connecting members may include first and second longitudinal connecting members joining a first hoop member to a second hoop member such that the first and second longitudinal connecting members extend across an entire space separating the first and second hoop members.
