摘要： A tubular suction tool (10) for accessing an anatomic surface or anatomic space and particularly the pericardium to access pericardial space and the epicardial surface of the heart to implant cardiac leads (90) in a minimally invasive manner are disclosed. The suction tool incorporates a suction pad (30) concave wall defining a suction cavity, a plurality of suction ports (42) arrayed about the concave wall, and a suction lumen, to form a bleb of tissue into the suction cavity when suction is applied. The suction cavity extends along one side of the suction pad, so that the suction pad and suction cavity can be applied tangentially against a tissue site. The suction tool can incorporate light emission (52) and video imaging of tissue adjacent the suction pad. A working lumen (20) terminating in a working lumen port (46) into the suction cavity enables introduction of tools, cardiac leads, and other instruments, cells, drugs or materials into or through the tissue bleb drawn into the suction cavity.

摘要： Flat electrolytic capacitors, particularly, for use in implantable medical devices (IMDs), and the methods of fabrication of same are disclosed. The capacitors are formed with an electrode stack assembly comprising a plurality of stacked capacitor layers each comprising an anode sub-assembly of at least one anode layer, a cathode layer and separator layers wherein the anode and cathode layers have differing dimensions that avoid electrical short circuits between peripheral edges of adjacent anode and cathode layers but maximize anode electrode surface area. The electrolytic capacitor is formed of a capacitor case defining an interior case chamber and case chamber periphery, an electrode stack assembly of a plurality of stacked capacitor layers having anode and cathode tabs disposed in the interior case chamber, an electrical connector assembly for providing electrical connection with the anode and cathode tabs through the case, a cover, and electrolyte filling the remaining space within the interior case chamber. The plurality of capacitor layers and further separator layers are stacked into the electrode stack assembly and disposed within the interior case chamber such that the adjacent anode and cathode layers are electrically isolated from one another. The anode layer peripheral edges of the anode sub-assemblies of the stacked capacitor layers extend closer to the case side wall than the cathode peripheral edges of the cathode layers of the stack of capacitor layers throughout a major portion of the case chamber periphery. The separator layer peripheral edges extend to the case periphery and space the anode layer peripheral edges therefrom. Any burrs, debris or distortions along or of any of the anode layer peripheral edges causing the anode layer edges to effectively extend in the electrode stack height direction causes the anode layer peripheral edges having such tendency to contact an adjacent anode layer. In this way, anode layer surface area is maximized, and short circuiting of the anode layers with the cathode layers is avoided. A case liner can also be disposed around the electrode stack assembly periphery.

摘要： A device for holding a surgical suture including a base, a guide body, a cam body, a bearing member, and a spring member. The base has a top side, a front edge, and a back edge. The guide body projects from the top side of the base and defines a guide face having an entrance side and an exit side. The entrance side is adjacent the front edge and the exit side is adjacent the back edge. The cam body is pivotally mounted to the top side and forms a toothed surface positioned to selectively secure a surgical suture against the guide face. The spring member is positioned between the cam body and the bearing member, biasing the toothed surface toward the guide face.
