Abstract: A seal assembly adapted for use in conjunction with a trocar assembly includes a plurality of seal segments. Each seal segment includes a peripheral edge and a seam edge. At least a first seal segment and a second seal segment are connected along their respective peripheral edges to form a first seal layer having a seam defined by the seam edge of the first seal segment and the seam edge of the second seal segment. At least a third seal segment and a fourth seal segment are connected along their respective peripheral edges to form a second seal layer having a seam defined by the seam edge of the third seal segment and the seam edge of the fourth seal segment. The seam of the first seal layer has a first longitudinal axis and the seam of the second seal layer has a second longitudinal axis, and the first seal layer is oriented relative to the second seal layer such that the first longitudinal axis is angularly oriented relative to the second longitudinal axis.

Abstract: A seal assembly adapted for use in conjunction with a trocar assembly includes a plurality of seal segments, each seal segment including a peripheral edge and a seam edge. Each seal segment further includes a first section and a second section with a vertical wall connecting the first section and the second section in such a way that the first section is displaced relative to the second section such that the first section of a first seal segment may be placed upon the second section of a second seal segment with the first sections of the first and second seal segments lying in the same plane and the second sections of the first and second seal segments lying in the same plane. The seal segments are assembled in an overlapping woven arrangement to provide a complete seal body without the need for a secondary seal.

Abstract translation: 适于与套管针组件一起使用的密封组件包括多个密封段，每个密封段包括周边边缘和接缝边缘。 每个密封段还包括第一部分和第二部分，其具有连接第一部分和第二部分的垂直壁，使得第一部分相对于第二部分移位，使得第一密封段的第一部分可以 被放置在第二密封段的第二部分上，第一和第二密封段的第一部分位于同一平面中，并且第一和第二密封段的第二部分位于同一平面内。 密封段以重叠编织布置组装以提供完整的密封体，而不需要二次密封。
