摘要： Described here are devices for closing one or more tissues, and handles for controlling these devices. Generally, the devices described here comprise a snare loop assembly, wherein the snare loop assembly comprises a snare loop and a suture loop, and a handle for controlling the snare loop assembly. In some variations the snare loop assembly may comprise a retention member that may releasably connect the suture loop to the snare loop. In other variations the devices comprise one or more force-reducing suture locks to help prevent the suture loop from inadvertently disengaging from the snare loop assembly. In still other variations, the excess-suture management features. The handles described here may be configured to remove excess suture from a suture loop, and may also be configured to release the suture loop from the snare loop assembly.

摘要： Delivery devices configured to deliver therapeutic and visualization devices to a surgical site are disclosed. An example delivery device may include a proximally disposed handle; a shaft extending distally from the handle, the shaft including a therapeutic device lumen configured to deliver a working end of a therapeutic device therethrough, a first portion of the shaft being steerable; and a space-making element disposed proximate a distal end portion of the shaft and configured to separate biological tissues to create or expand a working space. At least a portion of the space-making element may be reconfigurable between a retracted configuration and an expanded configuration.

摘要： A method of using an occlusion clamp, the method comprising: (a) repositioning a tongs so that tissue interposes the tongs, the tongs comprising a first longitudinal segment operatively coupled proximally to a second longitudinal segment, the tongs including a first spring exerting a proximal bias tending to direct a proximal portion of each of the first and second longitudinal segments toward one another, where each of the first and second longitudinal segments includes a distal free end; (b) repositioning a second spring distally along each of the first and second longitudinal segments to exert a bias tending to direct a distal portion of each of the first and second longitudinal segments toward one another, where repositioning of the tongs so that tissue interposes the tongs precedes repositioning the second spring distally along each of the first and second longitudinal segments.

摘要： Methods for using a surgical device integrating a suction mechanism with a coagulation mechanism for improving lesion creation capabilities. The device comprises an elongate member having an insulative covering attached about means for coagulating soft tissue with at least one diagnostic element coupled to an energy transfer element of the device. Openings through the covering expose regions of the coagulation-causing elements and are coupled to lumens in the elongate member which are routed to a vacuum source and a fluid source to passively transport fluid along the contacted soft tissue surface in order to push the maximum temperature deeper into tissue.

摘要： Pericardiotomy devices are disclosed. An example pericardiotomy device includes an elongated shaft and an end effector disposed distally on the shaft. The end effector includes a tip portion and a penetrating element. The tip portion includes an opening configured to engage a target portion of a pericardium and is configured, upon application of vacuum to the tip portion, to separate the target portion of the pericardium from an external surface of a heart. The penetrating element is disposed within the tip portion so that, with vacuum applied to the tip portion, the penetrating element is operative to create an opening in the target portion of the pericardium.
