Improved cardiac surgery retractor which comprises a baseband formed by a larger base and a smaller base, mutually arranged in a perpendicular manner and forming a cross-section of the baseband in the shape of an L, the smaller base being planar and the larger base having a curved geometry; the baseband incorporating a fin formed by a profile with a cross-section also in the shape of an L and the fin being articulated at the smaller base of the baseband, at a lateral edge of the smaller base contiguous to the contact thereof with the larger base of the same baseband; such that in one position of the joint of the fin, one of the sides of the L profile forming the fin is the continuation of the same smaller base and the other side of the same L profile of the fin is the continuation of the larger base.

A system includes and implant and an elongate device. The implant includes a first bone engaging portion and a flexible portion coupled to an end of the first bone engaging portion at an engagement portion. The flexible portion is configured to be compressed toward a longitudinal axis defined by the flexible portion. The elongate device includes an engagement end that is sized and configured to engage the engagement portion of the implant.

A method includes coupling, at least temporarily, a support member adjacent to a target tissue. The support member is configured to support the target tissue and to define a path along which a cutting device can move. The method includes moving the cutting device along the path defined by the support member to cut and/or dilate the target tissue. In some embodiments, the method optionally includes disposing a cannula of a device within the cut defined in target tissue. The cannula is coupled to the target tissue such that a lumen defined by the cannula is in fluid communication with a volume defined at least in part by the target tissue.

Methods and devices described herein facilitate improved treatment of body organs.

In order to easily and stably adhere an adhering body by suction to an easily deformable flexible object, the adhering body includes an elastically deformable body that moves back and forth between a closing position at which the elastically deformable body closes a communication port and an opening position at which the elastically deformable body opens the communication port, the elastically deformable body moving, in conjunction with movement of a movable contact part to a retreat position, so as to open the communication port.

A surgical instrument includes a mount body, a joint member, an arm, and a working end. The mount body has a top portion, a distal end, a proximal end and a bottom portion. The joint member is pivotally mounted at a distal end portion of the mount body, to allow positioning of a proximal portion of an arm extending distally from the joint member. The joint member is also configured to at least partially constrain movement of the proximal portion of the arm to a plane. The working end is mounted to a distal end portion of the arm. The surgical instrument can be configured as a heart stabilizer or a heart positioner. The joint member may further be configured as a slotted ball, a disk member, or a combination thereof.

A single-arm stabilizer having suction capability includes a single, small leg through which suction can be applied. The leg has an upper surface and a lower surface that are spaced apart to define a chamber. The lower surface includes a plurality of openings that are disposed adjacent each other. A support arm is connected to the leg in order to position the leg as desired. A suction line is in fluid communication with the chamber in order to create a vacuum within the chamber. The stabilizer can be used to stabilize any desired portion of a patient's body, but is particularly effective at stabilizing the septum of a patient's heart. Such stabilization can be accomplished by inserting the leg into the patient's heart through the aorta.

A minimally invasive heart stabilizer includes a guide tube, a revolute joint, a stabilizing end-effector, and a linkage. The guide tube is sized to allow insertion through an endoscopic cannula. The revolute joint is coupled to a distal end of the guide tube. The stabilizing end-effector is coupled to the revolute joint. The linkage has a distal end and a proximal end. The distal end is pivotally connected to the end-effector. The stabilizing end-effector includes two tissue engaging members in parallel alignment with one another. The two tissue engaging members are joined via an arrangement of links.

An ablation apparatus including a maneuvering mechanism, a conductive element attached to the apparatus, a sensor attached to the apparatus and an output device in communication with the sensor is provided. The sensor senses vibration during the ablation procedure and sends a signal to the output device to reduce power to the conductive element.
