    摘要: Methods and devices for perfusing a blood vessel during the entire course of an end-to-side or end-to-end anastomosis procedure. One method can be used to form an end-to-side anastomosis of a saphenous vein graft to a coronary artery during an off-pump, beating heart, coronary artery bypass graft. In this example, the distal end of an elongate tube carrying a saphenous vein graft is advanced into an arteriotomy distal to an occlusion in the coronary artery. Perfusing blood flow is provided through the tube to the coronary artery, the vein graft is advanced over the tube to the arteriotomy and sutured completely to the coronary artery. The elongate tube can be retracted through the now secured vein graft, and the coronary artery supplied again from the proximal end of the vein graft. Some tubular devices include a reversibly expandable distal region, to form a seal between the inserted tube and the coronary artery being perfused, to prevent blood flow into the surgical field.

    摘要: A tubular access sleeve and suction tool for accessing an anatomic surface or anatomic space and particularly the pericardium to access pericardial space and the epicardial surface of the heart in a minimally invasive manner are disclosed. A suction tool trunk extending through a suction tool lumen of the sleeve is coupled to suction pads at the ends elongated support arms. The suction pads can be retracted into a sleeve working lumen during advancement of the access sleeve through a passage and deployed from the tubular access sleeve lumen and disposed against the an outer tissue layer. Suction can be applied through suction tool lumens to suction ports of the suction pads that fix to the outer tissue layer so as to tension the outer tissue layer and/or pull the outer tissue layer away from an inner tissue layer so that the anatomic space can be accessed by instruments introduced through the working lumen to penetrate the outer tissue layer.

    摘要: An epicardial lead installation tool having an elongated tool body extending between a tool body proximal and distal ends and encloses a tool body lumen. At least one suction pad supported by a suction pad strut extends distally to a distal end surface of the tool body distal end. A lead implantation tool extending between implantation tool proximal and distal ends is inserted through the tool body lumen to dispose the implantation tool distal end proximate to the tool body distal end. The lead implantation tool distal end is adapted to engage the distal electrode head of an epicardial lead to enable the extension of the assembly of the of the lead installation tool, the lead implantation tool and the epicardial lead through a skin incision and to apply the suction pad against the epicardium. Suction is applied through the suction pad to affix it to the epicardium while the implantation tool proximal end is manipulated to affix the distal fixation mechanism to the myocardium at the implantation site.
