摘要:
The present invention relates to the field of non-biodegradable stents, and therein to non-biodegradable stents coated with at least one layer of a biodegradable polymer which maintains mechanical integrity of the coating both in storage and upon balloon expansion and which can optionally release drugs. The at least one polymer layer comprises a biodegradable polymer and a plasticizer. The present invention also relates to a manufacturing method of such a non-biodegradable stent.

摘要:
A tissue retractor for retracting tissue opened by an incision, said tissue retractor including a base support unit having a topside and an underside. The topside comprises at least one securing mechanism and the underside is adapted to be conformable and to be removably attachable to a surface proximate to the incision. The tissue retractor also includes at least one tissue hook having a tissue engagement portion and a mounting portion, wherein the tissue engagement portion is capable of engaging at least the periphery of the incision. The tissue retractor also includes at least one retractable member substantially inelastic in its central longitudinal axis and bendable in any axes deviating from said central longitudinal axis. The retractable member is adapted to receive the mounting portion of the tissue hook, wherein said retractable member is adapted to be removably attachable to said securing mechanism on the topside of the base support unit, and wherein said retractable member is retractable away from the incision, such that the tissue engagement portion retracts tissue it is engaged to.
