摘要:
An everter and threadthrough system useful for attaching a graft vessel to a anastomosis device which can be used to attach a graft vessel to a target vessel without the use of conventional sutures. The threadthrough system engages an end of the graft vessel and pulls the graft vessel through a deployment tool until a portion of the graft vessel extends beyond a distal end of the anastomosis device mounted on the deployment tool. The everter includes a spreading mechanism which expands the end of the graft vessel and folds the expanded end over the anastomosis device. In the case where the anastomosis device includes barbs, the everter can effect penetration of the graft vessel by the barbs. Once the graft vessel is everted over the anastomosis device, the deployment tool can be used to attach the graft vessel to a target vessel.

A device for everting an end of a hollow tissue structure may include a mandrel and a collar proximal to the mandrel. The mandrel may be elastomeric and deformable. At least one of the collar and the mandrel may be movable relative to the other. Deformation of the mandrel everts the end of the hollow tissue structure.

Methods and devices for treating nasal airways are provided. Such devices and methods may improve airflow through an internal and/or external nasal valve, and comprise the use of mechanical re-shaping, energy application and other treatments to modify the shape, structure, and/or air flow characteristics of an internal nasal valve, an external nasal valve or other nasal airways.
摘要:
Methods and devices are disclosed for manipulating the hyoid bone, such as to treat obstructive sleep apnea. A conformable implant is positioned adjacent a hyoid bone. The spatial orientation of the hyoid bone is manipulated, to affect the configuration of the airway. The implant restrains the hyoid bone in the manipulated configuration. The implant is positioned adjacent to pharyngeal structures to dilate the pharyngeal airway and/or to support the pharyngeal wall against collapse. The implant may be attached to the hyoid bone using a clamp delivery tool that is adapted to releasably engage the implant.
摘要:
Methods and devices for the treatment of airway obstruction, sleep apnea and snoring are disclosed. In some embodiments, a glossal suspension system includes a tissue tensioner that includes a suture loop made of one or more sutures configured to suspend the tongue with at least one portion configured to extend laterally through the tongue, and a securement mechanism configured to be attached to a patient's mandible that includes one more adjustment assemblies for engaging the one or more sutures and adjusting tension on the suture loop. Various tethers and anchors that can be used with the glossal suspension system are also disclosed.
摘要:
Methods and devices for rhinoplasty and treating nasal valve stenosis are disclosed herein. The nasal valve acts as a flow-limiter and can contribute to airway obstruction if resistance within the nasal valve is excessive. In one embodiment, a system for treating nasal valve stenosis includes a first elongate implant and a second elongate implant configured to support the nasal valves when implanted. The implants can be coupled together by connecting elements, such as eyelets, tethers, complementary socket joints, and button-rivet supports.

Disclosed is a closure catheter, for closing a tissue opening such as an atrial septal defect, patent foreman ovale, or the left atrial appendage of the heart. The closure catheter carries a plurality of tissue anchors, which may be deployed into tissue surrounding the opening, and used to draw the opening closed. Methods are also disclosed.
摘要:
Methods and devices are disclosed for manipulating the tongue. An implant is positioned within at least a portion of the tongue and may be secured to other surrounding structures such as the mandible and/or hyoid bone. In general, the implant is manipulated to displace at least a portion of the posterior tongue in an anterior or lateral direction, or to alter the tissue tension or compliance of the tongue. Methods and devices are also disclosed for manipulating other soft tissue structures, including the soft palate and pharyngeal airway.
