Abstract

A covering for delivering a substance or material to a surgical site is provided. The covering, with substance provided therein, may be referred to as a delivery system. Generally, the covering may be a single or multi-compartment structure capable of at least partially retaining a substance provided therein until the covering is placed at a surgical site. Upon placement, the covering may facilitate transfer of the substance or surrounding materials. For example, the substance may be released (actively or passively) to the surgical site. The covering may participate in, control, or otherwise adjust, the release of the substance.

Claims

1-101. -101. (canceled)

102. A delivery system comprising:

a covering comprising a first compartment, the covering including a physical attachment mechanism;

a first substance provided within the covering;

wherein the covering retains the substance for placement at a surgical site and facilitates transfer of the substance or of surrounding materials, actively or passively, upon implantation.

103. The delivery system of claim 102, wherein the physical attachment mechanism is a wrap.

104. The delivery system of claim 102, wherein the physical attachment mechanism is a suture.

105. The delivery system of claim 102, wherein the physical attachment mechanism is a wire.

106. The delivery system of claim 102, wherein the physical attachment mechanism is a string.

107. The delivery system of claim 102, wherein the physical attachment mechanism is an elastic band.

108. The delivery system of claim 102, wherein the physical attachment mechanism is a cable.

109. The delivery system of claim 102, wherein the physical attachment mechanism is a cable tie.

110. The delivery system of claim 102, further comprising a second compartment.

111. The delivery system of claim 110, wherein the covering comprises a first end and a second end and wherein the first and second compartments each extend from the first end to the second end.

112. The delivery system of claim 110, wherein the first and second compartments are arranged with the first compartment over the second compartment.

113. The delivery system of claim 110, wherein the covering comprises a first end and a second end and wherein the first compartment is adjacent the first end and the second compartment is adjacent the second end.

114. The delivery system of claim 110, wherein the first and second compartments are in communication.

115. The delivery system of claim 110, wherein the first compartment is formed of a first material and the second compartment is formed of a second material and wherein the first material and the second material are not the same.

116. The delivery system of claim 102, wherein the covering comprises a mesh.

117. The delivery system of claim 102, wherein the covering comprises a functional material.

118. The delivery system of claim 102, wherein the covering comprises a structural material.

119. The delivery system of claim 102, wherein the covering further comprises a reinforcing material.

120. The delivery system of claim 102, wherein the covering is flexible.

121. The delivery system of claim 102, wherein the substance is particulated and wherein the covering retains particles of the substance in spatial proximity to one another.

123. The delivery system of claim 102, wherein the covering is porous.

124. The delivery system of claim 102, wherein the covering comprises an actively releasing material and is configured to release such material during degradation of the covering.

125. The delivery system of claim 102, wherein the delivery system is tubular.

126. The delivery system of claim 125, wherein the tubular covering is configured for subdivision into smaller tubular compartments in an operating room.

127. The delivery system of claim 102, wherein the covering comprises an elongated containment portion and first and second ends and wherein the attachment mechanism is provided at at least one of the first and second ends.

128. The delivery system of claim 127, wherein the covering further comprises a seal at at least one of the first and second ends.

129. The delivery system of claim 102, wherein the attachment mechanism is integral to the covering.

130. The delivery system of claim 102, wherein the attachment mechanism is provided separately from the covering and is attached to the covering for use.

131. The delivery system of claim 102, wherein the attachment mechanism attaches the delivery system to a tissue structure.

132. The delivery system of claim 102, wherein the first substance is bone.

133. The delivery system of claim 102, further comprising a tension band.

134. The delivery system of claim 102, wherein the attachment mechanism cooperates with an attachment mechanism of a second covering.
