    摘要: Medical devices for cutting and suturing biological tissue generally include a shaft and first and second guide members each including a first portion coupled to the shaft at a first location and a second portion coupled to the shaft at a second location. The first portions are movable along the shaft relative to the second portions, and the first and second guide members define an arcuate profile and are configured to flex in response to such movement. When used to cut tissue, the medical device may further include a blade positioned between the first and second guide members. When used to suture tissue, one or more suture guides may be provided on the first guide member for directing a suture needle through tissue proximate the first guide member. Methods of repairing and replacing a meniscus using the medical devices are also provided.

    摘要: A method of preparing an implantable biological device having a first tissue part and a second tissue part includes exposing the first tissue part to a first preparation method and preventing exposure of the second biological tissue part to the first preparation method. Preventing exposure of the second biological tissue part to the first preparation method may be achieved using an embedding technique, a coating technique, a covering technique, or physical isolation. The method may further include exposing the second tissue part to a second preparation method and preventing exposure of the first biological tissue part to the second preparation method. An apparatus for preparing an implantable biologic device includes an enclosure having first and second chambers separated by a partition member wherein a substantial portion of the first tissue part is within the first chamber and a substantial portion of the second tissue part is within the second chamber.

    摘要: A device for delivering a biocompatible material to a surgical site includes an elongate cannula having a proximal portion, a distal portion, and at least one interior lumen disposed between the proximal and distal portions through which the biocompatible material is delivered. The device further includes a confinement member adjacent the distal portion of the cannula having expanded and unexpanded positions. In the expanded position, the confinement member defines an open cavity about the distal portion of the cannula and in fluid communication with the interior lumen to retain the biocompatible material. A method of delivering a curable biocompatible material to a surgical site includes positioning a distal portion of a cannula adjacent the surgical site and actuating a confinement member to define an open cavity about the distal portion. The biocompatible material is introduced into the cavity through the cannula and cross-linking of the curable biocompatible material is initiated.

    摘要: A device for delivering a biocompatible material to a surgical site includes a cannula having proximal and distal portions and at least a first interior lumen disposed therebetween through which the biocompatible material is delivered. The device further includes an initiation member for initiating cross-linking of the biocompatible material while the biocompatible material is within the cannula. The cannula may include a heating element to thermally initiate cross-linking. Alternately, the cannula may include a second lumen for transmitting light from a light source. A movable blocking element controls the amount of light that passes into the first lumen. A method of delivering a curable biocompatible material to a surgical site includes positioning a distal portion of a cannula adjacent the surgical site and introducing the biocompatible material through a first lumen of the cannula. Cross-linking of the biocompatible material is then initiated while the biocompatible material is within the cannula.
