Abstract: Synthetic anatomical members, such as a tympanic membrane and a malleus, are illustrated and a method for making them is disclosed. In accordance with the method, prepared collagenous tissue is placed in a mold and immersed in, or sprayed with, a buffered formaldehyde or functionally similar preservative. After removal from the mold, the tissue retains the shape assumed in the mold. Provisions are made for attaching other anatomical members, such as bone, to the tissue for use in, for example, en bloc reconstruction of an eardrum and ossicles.

Abstract: A biological vessel harvesting device is provided which separates a segment of a biological vessel from adventitia surrounding the biological vessel while simultaneously cauterizing and sectioning tributaries extending from the separated vessel segment. The biological vessel harvesting device includes an outer catheter and a vessel grasping mechanism positioned within a lumen of the outer catheter for holding an end of a segment of the biological vessel to be harvested, the outer catheter being movable relative to the vessel grasping mechanism such that the vessel grasping mechanism and the vessel segment attached thereto can be drawn into the outer catheter lumen. The biological vessel harvesting device also includes a cautery-sectioning system positioned adjacent the outer catheter distal end in a ring around the outer catheter lumen. The cautery-sectioning system has a cautery mechanism for cauterizing tributaries extending from the vessel segment about the circumference of the vessel segment and a sectioning device function for sectioning the cauterized tributaries.

Abstract: A probe for translumenal circumferential delivery of energy through a biological lumen comprises a catheter which is constructed and arranged to be placed within a particular biological lumen. A plurality of guide channels are formed within the catheter extending from near the proximal end to near the distal end of the catheter. The guide channels include respective diverting regions near the distal end which bend radially toward the circumference of the catheter. Energy delivery devices, such as optical fibers or electrical conductors, are placed within the guide channels and transmit energy to the distal end of the device. The energy delivery devices have relatively flexible portions near the distal ends such that when extended through the diverting region of the guide channels they are deflected radially in a direction to intersect the circumference of the biological lumen. An adaptor is coupled with the energy delivery device to supply energy for transmission to the tissue at the distal end of the device. Thus, the energy delivery device may be positioned in a withdrawn position in the catheter so that the distal end of the energy delivery device lies within the guide channel, and in an extended position so that the distal end of the energy delivery device is diverted by the diverting region of the guide channel and extends into the tissue to be treated.
Abstract translation: 用于通过生物腔内进行能量周向递送的探针包括构造和布置成放置在特定生物腔内的导管。 在导管内形成多个引导通道，其从近端附近延伸到导管的远端附近。 引导通道包括在远端附近朝向导管的圆周径向弯曲的各个转向区域。 诸如光纤或电导体的能量输送装置被放置在引导通道内并将能量传输到装置的远端。 能量输送装置在远端附近具有相对柔性的部分，使得当延伸通过导向通道的转向区域时，它们沿与生物腔的圆周相交的方向径向偏转。 适配器与能量输送装置耦合以提供能量以便传输到装置的远端处的组织。 因此，能量输送装置可以定位在导管中的撤回位置，使得能量输送装置的远端位于引导通道内，并且处于延伸位置，使得能量输送装置的远端被转移 引导通道的转向区域并延伸到待治疗的组织中。
