    • Methods and device for extracting and collecting tissue, which can be used for example in tissue engineering and grafting applications, are disclosed. In one embodiment, a device can include an outer tube. A rotatable shaft can be disposed within the outer tube can have a tissue harvesting tip formed on its distal end, the tissue harvesting tip being effective to excise tissue upon rotation thereof. A tissue collection device can be included to receive and collected excised tissue, and the tissue collection device can indicate the amount of tissue collected therein. For example, the tissue collection device can include a straining element which collects excised tissue and an indicator by which to assess the amount of collected tissue. In some embodiments, the tissue collection device can translate to indicate the amount of collected tissue. In many cases, devices disclosed herein can include driving mechanisms that are adapted to drive a tissue harvesting tip such that the tip excises soft tissue, but stops when contacting bone (or soon after contacting bone). In some embodiments, the tissue harvesting tip can be effective to excise viable tissue samples, such that the samples can exhibit desirable proportions of viable cells. Further, in some embodiments, the tissue harvesting tips can excise a tissue sample with tissue particles falling in certain size ranges.
    • 公开了用于提取和收集组织的方法和装置,其可以用于组织工程和移植应用中。 在一个实施例中,装置可以包括外管。 旋转轴可以设置在外管内,可以具有形成在其远端上的组织收集尖端,组织收集尖端有效地在旋转时切除组织。 可以包括组织收集装置以接收和收集切除的组织,并且组织收集装置可以指示其中收集的组织的量。 例如,组织收集装置可以包括收集切除的组织的应变元件和用于评估收集的组织的量的指示器。 在一些实施例中,组织收集装置可以平移以指示收集的组织的量。 在许多情况下,本文公开的装置可以包括适于驱动组织收集尖端的驱动机构,使得尖端切除软组织,但是当接触骨骼时(或者在接触骨骼之后不久)停止。 在一些实施方案中,组织采集尖端可有效地切除活组织样品,使得样品可以显示出所需比例的活细胞。 此外,在一些实施例中,组织采集尖端可以用落在一定尺寸范围内的组织颗粒来切除组织样本。

    • A composite implant is provided for repairing a tissue defect in a patient. In one embodiment, the implant is a porous tissue scaffold having at least one pocket formed therein and adapted to contain a viable tissue. The tissue scaffold can have a variety of configurations, and in one embodiment it includes top and bottom portions that can be at least partially mated to one another, and in an exemplary embodiment that are heated sealed to one another around a perimeter thereof to form an enclosed pocket therebetween. The pocket is preferably sealed with a viable tissue disposed therein. In another embodiment, the tissue scaffold is substantially wedge-shaped and the pocket comprises a hollow interior formed in the tissue scaffold, and/or at least one lumen extending into the tissue scaffold. The tissue scaffold can also optionally include at least one surface feature formed thereof to promote blood vessel formation.
    • 提供复合植入物来修复患者的组织缺损。 在一个实施例中,植入物是多孔组织支架,其具有形成在其中的至少一个口袋并且适于容纳活组织。 组织支架可以具有各种构造,并且在一个实施例中,其包括可以彼此至少部分地配合的顶部和底部部分,并且在示例性实施例中,围绕其周边彼此加热密封以形成 封闭口袋。 口袋优选用设置在其中的活组织密封。 在另一个实施例中,组织支架基本上是楔形的,并且口袋包括形成在组织支架中的中空内部和/或延伸到组织支架中的至少一个腔。 组织支架还可以任选地包括形成于其中的至少一个表面特征以促进血管形成。

    • A system for delivering a flowable substance capable of changing from liquid to solid for use as implants and surgical sealants includes a first reservoir containing a first flowable substance including a bulking agent, a second reservoir containing a second flowable substance including a reacting agent, and a cannula. A method of delivering flowable substance that changes from liquid to solid for use as implants and surgical sealants includes introducing a cannula having first and second lumens into the body, passing a flowable substance including a bulking agent through the first lumen, passing a second flowable substance including a reacting agent through the second lumen, mixing the first and second flowable substances in the cannula so that the bulking agent reacts with the reacting agent to form a flexible elongated fiber in the cannula, and moving the fiber through the opening in the cannula and into the body to form at least one of an implant and surgical seal.
    • 用于输送能够从液体变为固体以用作植入物和手术密封剂的可流动物质的系统包括:第一储存器,其包含含有填充剂的第一可流动物质;第二储存器,含有包含反应剂的第二可流动物质;以及 套管。 一种输送从液体变为固态的可流动物质的方法,用作植入物和手术密封剂包括将具有第一和第二内腔的套管引入体内,使包含填充剂的可流动物质通过第一腔,通过第二可流动物质 包括通过所述第二腔的反应剂,将所述第一和第二可流动物质混合在所述套管中,使得所述填充剂与所述反应剂反应以在所述套管中形成柔性细长纤维,并且通过所述插管中的所述开口移动所述纤维, 进入体内以形成植入物和手术密封件中的至少一个。
