摘要:
A medical device includes a substrate having at least one surface. The surface has a central portion and a peripheral portion. At least one bioactive agent is disposed over at least a portion of the surface. The medical device having a concentration gradient of the at least one bioactive between the central and peripheral portions.
摘要:
A seal anchor member has opposing ends that define a longitudinal axis. The seal anchor member is adapted to transition between an expanded condition and a compressed condition to facilitate securing of the seal anchor member within a tissue tract in a substantially sealed relationship. The seal anchor member includes a biasing member positioned along the longitudinal axis. The biasing member is configured and adapted to facilitate the transition between the expanded and compressed conditions. The seal anchor member further includes at least one lumen extending through the seal anchor member for slidably receiving a surgical instrument.
摘要:
A sheath is configured for elongation from a first length to a second, longer length and a retention member retains the sheath at the first length. A portion of the retention member is removed or disengaged, the sheath is released and expands in situ to the second longer length. A method for releasing the retention member is also disclosed.
摘要:
A sheath is affixed to a body lumen, proximal to an anastomosis site. The sheath includes a sleeve defining a passage. A first ring-shaped member or balloon, attached to a proximal portion of the sleeve, is positioned proximal to an anastomosis and a second ring-shaped member or balloon, attached to a distal portion of the sleeve, is positioned distal to an anastomosis. The sleeve is further elongated from a first length to a second longer length. A method for using the sheath is also disclosed.
摘要:
Filament-reinforced composite fibers made from a plurality of filaments and a matrix are useful in forming medical devices such as sutures and meshes.
摘要:
An apparatus for supporting tissue during compression prior to the insertion of a surgical element into the tissue has a substrate. The substrate is made from a predetermined material. The predetermined material has a thickness and a predetermined stress strain profile. The predetermined stress strain profile is complementary to a stress strain profile of the tissue and permits the substrate to support the tissue when the surgical element is delivered into the tissue. The substrate provides hemostasis control of the tissue when the surgical element is delivered into the tissue.
摘要:
The present disclosure provides a package for a medical device having a surface prepared for receiving a target agent and a port for permitting the passage of the target agent between the surface of the medical device contained therein.
