This application is a continuation-in-part of U.S. patent application Ser. No. 11/347,661 filed on Feb. 3, 2006. This application is also a continuation-in-part of U.S. patent application Ser. No. 11/294,694 filed Dec. 5, 2005, which is a continuation-in-part of U.S. patent application Ser. No. 10/984,624 filed Nov. 9, 2004. The disclosures of the above applications are incorporated herein by reference.
Tears caused by trauma or disease in soft tissue, such as cartilage, ligament, or muscle, can be repaired by suturing and/or use of various fixation devices. Various tissue fixation devices have been developed for facilitating suturing and are effective for their intended purposes.
Although the existing soft tissue fixation devices can be satisfactory for their intended purposes, there is still a need for new devices that provide conduits for facilitating healing and promoting soft tissue vascularity.
The present teachings provide a soft tissue conduit device. The device includes an elongated body having an outer surface, the elongated body defining a plurality of longitudinal external channels, each longitudinal channel defining a conduit open to the outer surface of the elongated body, each conduit operable to conduct a biological material in soft tissue.
The present teachings also provide a method of conducting biological materials to a defect in soft tissue. The method includes inserting a conduit device into the soft tissue and through the defect in the soft tissue, and conducting biological materials along at least one longitudinal channel defined on an outer surface of the conduit device into the soft tissue.
The present teachings further provide a method of conducting biological materials between first and second areas of different vascularity of a meniscus. The method includes inserting an elongated body in the meniscus such that at least one longitudinal channel of the elongated body extends between the first and second areas and defines a conduit for biological materials, wherein the channel is open to an outer surface of the elongated body.
Further areas of applicability of the present invention will become apparent from the description provided hereinafter. It should be understood that the description and specific examples are intended for purposes of illustration only and are not intended to limit the scope of the invention.
The present invention will become more fully understood from the detailed description and the accompanying drawings, wherein:
The following description is merely exemplary in nature and is in no way intended to limit the invention, its application, or uses. For example, although the present teachings are illustrated for repairing meniscal defects in knee surgery, the present teachings can be used to repair and facilitate healing or regeneration of any injured soft tissue.
Referring to FIGS. 1A-C, an exemplary soft tissue conduit device 100 according to the present teachings includes an elongated body 102 having an outer surface 104 and a plurality of longitudinal external channels 106 extending along the entire length of the body 102. The channels 106 are shaped such that when the conduit device 100 is inserted into soft tissue, the channels 106 can serve as conduits for conducting biological materials, such as nutrients, into the tissue from outside the tissue or between first and second areas of the tissue, such as, for example, between healthy tissue and injured or torn tissue, or between areas of different vascularity, such as between red-red (vascular), red-white (semi-vascular) and white (avascular) tissue areas of a meniscus. The channels 106 can provide a vascularity path in the tissue for facilitating healing or repair. As such, each channel 106 can have a width “w” and a depth “d” that allows the tissue to envelope or form a “tent” over the channel 106 without blocking the channel 106. Referring to
Various biological materials can be delivered through the channels 106 by external cannulas or other pumping devices during or after implantation. Such biological materials can be in the form of autologous cells derived from blood or bone marrow aspirate, for example, or other appropriate exogenous biological materials. Native or endogenous biological materials can also be carried after implantation from a vascular region of the soft tissue 80 to the injured site by inserting the conduit device 100 such that the conduit device 100 extends from a vascular region of the soft tissue to the injured site. Additionally or alternatively, biological materials in the form of platelet gels can be deposited in the channels 106 before implantation, as another mechanism of biological material delivery, including nutrient, delivery.
Similarly, two non-cannulated conduit devices 100 a, 100 b can be coupled with corresponding fixation devices 140 a, 140 b using the flexible strand 142, as shown in
It will be appreciated from the above description that the conduit devices 100 can be used for many applications in which biological materials or nutrients are needed to be delivered to a soft tissue site or transferred from one tissue site to another. The longitudinal channels 106 of the devices coupled with dimensions that facilitate tenting of tissue provide unobstructed and continuous paths for the flow or delivery of such biological materials and nutrients.
The foregoing discussion discloses and describes merely exemplary arrangements of the present invention. One skilled in the art will readily recognize from such discussion, and from the accompanying drawings and claims, that various changes, modifications and variations can be made therein without departing from the spirit and scope of the invention as defined in the following claims.
