摘要： The invention provides devices, systems and methods for tissue approximation and repair at treatment sites. The devices, systems and methods of the invention will find use in a variety of therapeutic procedures, including endovascular, minimally-invasive, and open surgical procedures, and can be used in various anatomical regions, including the abdomen, thorax, cardiovascular system, heart, intestinal tract, stomach, urinary tract, bladder, lung, and other organs, vessels, and tissues. The invention is particularly useful in those procedures requiring minimally-invasive or endovascular access to remote tissue locations, where the instruments utilized must negotiate long, narrow, and tortuous pathways to the treatment site. In addition, many of the devices and systems of the invention are adapted to be reversible and removable from the patient at any point without interference with or trauma to internal tissues.

摘要： Disclosed are methods, systems, and devices for the endovascular repair of cardiac valves, particularly the atrioventricular valves which inhibit back flow of blood from a heart ventricle during contraction. The procedures described herein can be performed with interventional tools, guides and supporting catheters and other equipment introduced to the heart chambers from the patient's arterial or venous vasculature remote from the heart. The interventional tools and other equipment may be introduced percutaneously or may be introduced via a surgical cut down, and then advanced from the remote access site through the vasculature until they reach the heart.

摘要： The present invention provides methods and devices for grasping, and optional repositioning and fixation of the valve leaflets to treat cardiac valve regurgitation, particularly mitral valve regurgitation. Such grasping will typically be atraumatic providing a number of benefits. For example, atraumatic grasping may allow repositioning of the devices relative to the leaflets and repositioning of the leaflets themselves without damage to the leaflets. However, in some cases it may be necessary or desired to include grasping which pierces or otherwise permanently affects the leaflets. In some of these cases, the grasping step includes fixation.

摘要： A side-cutting atherectomy catheter with a housing containing a tissue-removal means, a window on one side, and a large volume inflatable support on the opposite side. The large volume inflatable support has a maximum diameter larger than the diameter of the cutter housing, generating a greater degree of contact with a blood vessel's interior diameter than conventional balloon-housing configurations. This feature stabilizes the cutter housing and improves tissue-removal during the atherectomy procedure. Large volume inflatable supports have a maximum inflated diameter at least 1.1 times, and preferably 1.35 times, greater than the diameter of the housing. The supports may be formed from either elastic or inelastic materials. When formed from inelastic materials, the supports have slack material when uninflated which can extend into and become entangled with the cutter window. To prevent this problem, the large volume inflatable support is constrained when uninflated. The means for constraining the support generally comprises balloon structures, housing structures, or storage or shielding features. In a preferred embodiment, the large volume inflatable support comprises a balloon formed with a plurality of preferential longitudinal folds. When deflated, the folds cause the balloon to form an overlapping flap of material which constrains the slack balloon material from extending around the housing and becoming entangled in the cutter window.
摘要翻译：一种具有壳体的侧切性粥样斑块切除术导管，其包含组织移除装置，一侧上的窗口和相对侧上的大体积可充气支撑件。大体积的可充气支撑件的最大直径大于切割器壳体的直径，与常规球囊壳体构造相比，产生与血管内径更大程度的接触。该功能使切割器壳体稳定，并且可以改善粥样斑块切除术过程中的组织去除。大容积充气支撑件的最大充气直径比壳体的直径大至少1.1倍，优选为1.35倍。支撑件可以由弹性材料或非弹性材料形成。当由非弹性材料形成时，当未膨胀时，支撑件具有松弛的材料，其可以延伸到切割窗口并与切割窗口缠结。为了防止这个问题，当未充气时，大体积的充气支撑被约束。用于约束支撑件的装置通常包括球囊结构，壳体结构或存储或屏蔽特征。在优选实施例中，大体积可充气支撑件包括形成有多个优先纵向折叠的气囊。当放气时，褶皱导致气囊形成重叠的材料折片，其限制松弛球囊材料围绕壳体延伸并且缠结在切割窗口中。

摘要： An athetectomy catheter is disclosed having a composite cutter which is capable of cutting material, including hardened plaque, from a biological conduit. The composite cutter has a cutter and a sensor mount. The cutter has a proximal end and a distal end with a cutting edge. The proximal end of the cutter bonds with the sensor mount. The sensor mount is adaptable for holding a sensor and attaching to a cutter torque cable of an atherectomy catheter. Typically, the atherectomy catheter has a cutter housing with a window. The composite cutter is positioned in the cutter housing and moves in response to movement of the cutter torque cable to cut material from the biological conduit via the window.

摘要： The present invention provides devices, systems, methods and kits for endoscopically accessing a body cavity and providing a directed pathway toward a target tissue within the cavity. The directed pathway is provided by an access sheath which is positioned in a desired configuration, generally directed toward the target tissue. Depending on the location of the target tissue and the desired angle of approach, the access sheath may be required to maintain one or more curves in one or more planes to properly direct the interventional devices. In addition, the access sheath has a locking feature to hold the sheath in place and maintain the desired configuration. Interventional devices may then be passed through the sheath to the target tissue.

摘要： The invention provides devices, systems and methods for tissue approximation and repair at treatment sites. The devices, systems and methods of the invention will find use in a variety of therapeutic procedures, including endovascular, minimally-invasive, and open surgical procedures, and can be used in various anatomical regions, including the abdomen, thorax, cardiovascular system, heart, intestinal tract, stomach, urinary tract, bladder, lung, and other organs, vessels, and tissues. The invention is particularly useful in those procedures requiring minimally-invasive or endovascular access to remote tissue locations, where the instruments utilized must negotiate long, narrow, and tortuous pathways to the treatment site. In addition, many of the devices and systems of the invention are adapted to be reversible and removable from the patient at any point without interference with or trauma to internal tissues.

摘要： Apparatus for creating an anatomic space in tissue in a body including an introducer device having a tubular member with a bore extending therethrough. A tunneling shaft assembly is slidably mounted in the bore of the introducer device. The tunneling shaft assembly includes a tunneling shaft having proximal and distal extremities. A blunt tip is secured to the distal extremity of the tunneling shaft. A balloon assembly is provided. The balloon assembly is removably secured to the tunneling shaft. The balloon assembly includes a deflated collapsed balloon. A sheath encloses the balloon and is carried by the tunneling shaft. The sheath has a weakened region extending longitudinally thereof permitting the sheath to be removed to release the balloon.
