The present technology relates generally to endovascular prostheses. More particularly, the disclosure relates to endovascular prostheses having an outer surface of a graft material thereof associated with a hydrogel composition, which may swell upon implantation within a blood vessel, thereby mediating various complications associated with endovascular procedures. The hydrogel compositions can also include various stabilizing polymers and active agents to further aid their use in the body.

Coated endovascular prostheses for aneurism treatment

A prosthetic assembly for repairing a target tissue defect within a target vessel region configured includes an exclusion structure sized to substantially bypass target tissue defect, and includes a branch assembly. The branch assembly can include a self-expanding outer branch prosthesis having an inflow region configured to deform to a non-circular cross-sectional-shape when deployed, and a support structure at least partially disposed within the inflow region. The support structure preserves blood flow to the branch vessel while the deformed inflow region inhibits blood leakage between and/or around the prosthetic assembly.

Endoluminal prosthetic assemblies, and associated systems and methods for percutaneous repair of a vascular tissue defect

A needle lattice is used to form openings within a graft material to selectively enhance permeability of a prosthesis for tissue integration therein. The needle lattice may be disposed on, for example, a surface of a roller or press. The needle lattice precisely places openings in any pattern and location, and on any textile that forms the graft material. The needle lattice can be heated to fuse the surrounding material of the openings of the textile to prevent movement of the textiles and to prevent collapse of the openings. All parameters of the openings, including varying density, patterns, and size of each opening, can be controlled, allowing for the opportunity to selectively enhance and optimize the permeability of the graft material in a vessel. The needle lattice can quickly form multiple openings within a graft material, allowing for quick manufacturing of the prosthesis.

Graft material having heated puncture structure and method

A scaffolded stent-graft includes a graft material comprising an inner surface and an outer surface. The inner surface defines a lumen within the graft material. The scaffolded stent-graft further includes a scaffold comprising a mesh coupled to the graft material at the outer surface. The scaffold is configured to promote tissue ingrowth therein. In this manner, the scaffold enhances tissue integration into the scaffolded stent-graft. The tissue integration enhances biological fixation of the scaffolded stent-graft in vessels minimizing the possibility of endoleaks and migration.

Stent graft with external scaffolding and method

A system for forming a suture connector in situ includes a suture connector placement device having a handle, an outer shaft, an intermediate shaft, and a push rod, and a suture connector having a sleeve and a plug. The intermediate shaft is slidingly disposed through a lumen of the outer shaft, and the push rod is slidingly disposed through a lumen of the intermediate shaft. When the suture connector is in a loaded configuration within the suture connector placement device, the sleeve is radially disposed over the intermediate shaft and the plug is positioned proximal to the sleeve within the lumen of the intermediate shaft. Distal advancement of the push rod moves the plug into the sleeve and proximal retraction of the intermediate shaft releases the resilient sleeve onto the plug, thereby securing two suture portions between the sleeve and the plug. The system is then utilized to trim the suture portions.

Method and apparatus for forming a suture connector in situ

A suturing device includes a handle, an elongated body, at least one suture snag, at least one pair of needles, and at least one suture pair. The suture snag is moveable between a deployed position in which two distal arm portions thereof radially extend away from the elongated body and a retracted position in which the two distal arm portions are disposed within the elongated body. The suture pair is slidingly disposed through the needle pair. The suturing device deploys the suture snag within a vessel adjacent to an arteriotomy, extends the needle pair through a vessel wall around the arteriotomy and through the deployed suture snag, extends the suture pair beyond the distal ends of the needle pair, and then utilizes the suture snag to capture the extended suture pair by retracting the suture snag to pull first or distal ends of the sutures back into the suturing device. An inflatable balloon or an expandable suture capture component may be alternatives to the suture snag for capturing the suture ends.
