摘要： An expandable probe and a method of delivering energy to a tissue using the expandable probe are provided. The expandable probe includes an elongate shaft having a proximal portion, a distal portion, a lumen extending at least partially therethrough and a longitudinal axis. The expandable probe also includes an arm operably connected to the distal portion. The arm has a first surface including an electrode extending over at least a portion of the first surface and the electrode is operably connectable to an energy source. The arm has a closed configuration and an expanded configuration where the arm in the closed configuration extends substantially parallel to the longitudinal axis and in the expanded configuration the arm extends away from the longitudinal axis.

摘要： Embodiments include a fiducial deployment system with a handle configured for actuation of same. A fiducial may include one or more protuberances configured to engage one or more slots in a needle of the system. The needle may be configured to deliver a plurality of fiducials to a target location in serial fashion, one at a time. In certain embodiments, echogenic placement of fiducials may present certain advantages. The handle may include structures configured for incrementally or otherwise controlledly deploying one or more fiducials by advancing a stylet through and/or retracting the body of a needle in which fiducials are disposed.

摘要： The present embodiments provide apparatus and methods for treating tissue by applying a force to the tissue. In one embodiment, the apparatus comprises a deployable segment having proximal and distal regions, a main body extending therebetween, and a loop member formed at the distal region of the deployable segment. A cannula having a bore is dimensioned to circumferentially surround at least a portion of the main body at a location proximal to the loop member, and a spring member is disposed between the cannula and the loop member. The proximal end of the spring member is affixed to the cannula, and the distal end of the spring member is movable to apply a compressive force to adjust the size of the opening of the loop member and compress tissue disposed within the opening of the loop member. In an alternative embodiment, the cannula is omitted, and a diameter of the loop member is configured to be reduced and increased any number of times before final deployment of the deployable segment.

摘要： The present embodiments provide a removable medical device, comprising a sleeve having proximal and distal ends and a lumen extending therebetween. At least one support member having an expanded deployed configuration is coupled to the sleeve using at least one permanent connector. A patch member comprising a resorbable material is coupled to at least a portion of an outer surface of the sleeve using at least one temporary connector. In use, when the support member is in the expanded deployed configuration, at least a portion of the patch member contacts the target site and fluid flows through the lumen of the sleeve. In a separate procedure, a retrieval member is operable to facilitate removal of the sleeve and support member while leaving the patch member disposed within the bodily passageway.
