摘要:
A sutureless anastomosis systems for securing a bypass graft to a host vessel or other tubular structure including a bypass graft and fitting. A compression mechanism may be used with the system for attachment of the bypass graft to the fitting. An electrode is connected to the fitting and an energy source. The energy source transmits energy to the electrode and causes the adjacent tissue to rise in temperature and bond to a vessel or fitting.

Systems and associated methods position arrays of multiple emitters of ablating energy in straight or curvilinear positions in contact with tissue to form elongated lesion patterns. The elongated lesion patterns can continuous or interrupted, depending upon the orientation of the energy emitters.

Systems and methods support arrays of multiple electrodes in asymmetric pattern, either radially, or axially, or both. Radial asymmetry makes it possible provide localized density of electrodes. Axial asymmetry makes it possible to locate electrodes in a pattern that closely conforms to the irregular contours of an interior body cavity, like the heart. In a preferred embodiment, the systems and methods operate the multiple electrode arrays to form continuous lesion patterns.

Compound steering assemblies, usable in both diagnostic and therapeutic applications, enable a physician to swiftly and accurately steer the distal section of the catheter in multiple planes or complex curves to position and maintain ablation and/or mapping electrodes in intimate contact with an interior body surface.

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.

Devices, systems and methods for fixation of tendon to bone are described. An exemplary surgical implant is a modified bone anchor that is able to grasp the tendon and hold it firmly in a bone tunnel. Once deployed, the anchor delivers lateral compression to the tendon, providing direct tendon to bone compression to facilitate healing. The anchor has different versions which allow it to be attached to the tendon prior to insertion into the bone tunnel, or be inserted between tendon arms when the surgical procedure dictates. The resulting tendon to bone compression allows for the firm fixation in a manner markedly simpler than traditional techniques. A modification of this anchor can also allow the anchor to grasp and hold suture. This variation facilitates the technique for knotless rotator cuff repair.
