    摘要: One aspect of the present invention relates to bronchoscopic lung volume reduction using solutions of biopolymers that can be polymerized in situ with a crosslinker and a polymeric additive which accelerates the cross-linking reaction. In certain embodiments, the biopolymer solutions can be in the form of a foam or gel. The biopolymer compositions disclosed herein may also be used for indications other than lung volume reduction, such as sealing fistulas or performing emergency tamponade of vessels.

    摘要: One aspect of the invention relates to a hydrogel comprising a non-natural polymer comprising a plurality of pendant nucleophilic groups and a crosslinker comprising at least two pendant electrophilic groups. Another aspect of the invention relates to a hydrogel comprising a non-natural polymer comprising a plurality of pendant electrophilic groups and a crosslinker comprising at least two pendant nucleophilic groups. Yet another aspect of the invention relates to a method for reducing lung volume in a patient comprising the step of administering a hydrogel composition as described herein. Further, hydrogels of the invention may be used to achieve pleurodesis, seal brochopleural fistulas, seal an air leak in a lung, achieve hemostasis, tissue sealing (e.g., blood vessels, internal organs), or any combination thereof. In certain embodiments, the compositions and methods described herein are intended for use in the treatment of patients with emphysema.

    摘要: A hand-held apparatus that delivers pressurized breathing gas to the airway of a patient, thereby creating positive end expiratory pressure (PEEP) and reducing respiratory muscle fatigue. The apparatus includes a deformable reservoir, a breathing interface, and a pressure relief valve. The apparatus may include a means for creating fluid communication between the deformable reservoir and a source of pressurized breathing gas. The apparatus may also include an adjuster that allows a user to vary the pressure of the breathing gas contained in the deformable reservoir.
