摘要:
A wound dressing system that includes a conformal cover and an infusion pump is provided. The cover includes a fluid port and an oxygen catalyst. The infusion pump is configured to deliver a bioactive liquid to the cover via the fluid port. The liquid includes an oxygen precursor. Upon combination, the oxygen catalyst and precursor react to form oxygen. A method of applying a wound dressing system including a bioactive powder, a bioactive liquid, and a conformal cover to a wound site is also provided. The method includes applying the powder to the wound site; securing the cover around the wound site, where the cover includes an oxygen catalyst and a fluid port; and delivering the bioactive liquid to at least an inner layer of the cover via the fluid port, where the bioactive liquid includes an oxygen precursor.
摘要:
Devices and methods for making anastomoses between hollow structures are disclosed. Certain of the devices employ expandable structures to allow insertion of the devices in a first, unexpanded position, and subsequent expansion of the devices to help form an anastomosis. A variety of different structures for such expandable devices, different expanders and different actuators are disclosed. Also disclosed are a variety of different methods for making an anastomosis between hollow structures, which involve expansion of an expandable structure. The devices and methods provide for a number of different type of anastomoses, as well as addressing several of the problems that are typically encountered when making anastomoses between hollow structures.
摘要:
A wound dressing system comprising a wrap and a frangible ampoule is provided. The wrap is configured to contact/surround a wound site and includes an oxygen catalyst. The ampoule includes an oxygen precursor. The catalyst and precursor are configured to form oxygen when combined. A wound dressing system including a container is also provided that includes a powder, wrap, and frangible ampoule. The powder is disposed within the container, which is configured to allow the powder to be dispersed onto a wound site when activated. The wrap, which may include an oxygen catalyst, is also disposed in the container and is configured to contact/surround the wound site. The ampoule, also disposed in the container, includes a liquid containing an oxygen precursor. The liquid is configured to contact the wrap when the container is activated. Further, the catalyst and precursor are configured to form oxygen when combined.
