A catheter includes a tubular body to be inserted into a living body. The tubular body has a lumen that is held in fluid communication with an injection port defined in a distal end of the tubular body and a suction port near a proximal end of the tubular body, and the suction port is closed when the injection port is open, and the injection port is closed when the suction port is open.

The present invention relates to a needle-free injector using pulsed shock waves, the needle-free injector comprising: a power unit generating pulsed power; a pulsed shock wave generating unit which receives the pulsed power and generates pulsed shock waves; an upper housing in which a liquid and the pulsed shock wave generating unit are disposed; a lower housing which is connected to the upper housing, and in which a drug is disposed; a shock wave transmission unit which is provided between the upper housing and the lower housing to separate the upper housing and the lower housing; and an injection unit which is disposed in the lower housing and inject the drug.

A system for treatment of an open wound in a chest of a patient is disclosed. The system includes a seal membrane configured to adhere to the chest and having an air passage. The system also includes a mechanism removably coupled to the seal membrane over the air passage. The mechanism is configured to allow air to pass through the mechanism in a first direction and not to pass in a second direction opposite the first direction.

Needleless connectors are described. An example needleless connector includes a housing and a compressible valve. The housing may define an internal cavity and may include a body section having a first port and one or more internal contact tabs and a base section having a valve mount and a second port. The compressible valve may be disposed within at least a portion of the internal cavity and be movably retained within the housing. The compressible valve may include a flange portion for securing the compressible valve within the housing. A central longitudinal axis of the housing may be defined by a coaxial arrangement of the first and second port. The one or more internal contact tabs may be arranged to contact an outer side surface of the flange portion such that a radial force substantially orthogonal to the central longitudinal axis is provided for securement.

In alternative embodiments, the invention provides compositions, e.g., formulations, used for gastric, gastrointestinal and/or colonic treatments or lavage, e.g., orthostatic lavage, e.g., for inducing the purgation (e.g., cleansing) of a gastrointestinal (GI) tract, including a colon; and methods for making and using them. In alternative embodiments, compositions and methods of the invention are used for the stabilization, amelioration, treatment and/or prevention of constipation, for the treatment of abdominal pain, particularly non-specific abdominal pain, and diarrhea, including diarrhea caused by a drug side effect, a psychological condition, a disease or a condition such as Crohn's Disease, a poison, a toxin or an infection, e.g., a toxin-mediated travelers diarrhea, or C. difficile or the pseudo-membranous colitis associated with this infection. In alternative embodiments, the invention provides pharmaceuticals and products (articles) of manufacture for delivering these compositions and formulations to an individual, e.g., a human or an animal. The invention also provides devices for delivering a fecal material to a patient.

A surgical instrument includes a housing (20), a syringe carriage (40), a movable handle (25), a shaft (30), a needle sheath (50), and a needle (60). The syringe carriage is operably coupled to the housing and configured to couple to a syringe. The movable handle is movable relative to the housing and operably coupled to the syringe carriage to distally advance the syringe carriage. The shaft extends distally from the housing and defines a lumen. The needle sheath extends through the lumen of the shaft, defines a lumen, and is movable relative to the shaft between an extended condition and a retracted condition. The needle extends through the lumen of the needle sheath and is configured to operably couple to a syringe coupled to the syringe carriage.
