Abstract
A malleable implant for implantation into living tissue is prepared having access means for cells into the interior of the implant. The implant is capable of being deformed under pressure required to insert the implant into an implant site. The access means can be hollow or solid. The solid comprises a material that more rapidly resorbs in vivo than the malleable implant to provide channels, or comprises a mechanically weak material that fractures under force at an implant site to produce channels or cracks. The access means may be inserted in the malleable implant at an implant site. A multilaminar structure may be formed having layers of malleable implant and layers of access means, or the access means may be heterogeneously distributed throughout the malleable implant. A kit can contain a powder such as calcium phosphate for making a paste implant material, and an access means insertable into the paste.
