Abstract: Devices and methods for compressing a patient's limb or limbs (e.g., legs or arms) for treating or preventing ailments due to compromised venous or lymphatic circulation of the limb. Exemplary embodiments include, but are not limited to, sub-atmospheric compression, micro-pneumatic compression, and active fabric compression devices and methods.

Abstract: Devices and methods for maintaining an open airway are described. Systems and methods are described for maintaining an opening of an airway by application of force to a patient's tissues in one of inferior, anterior, and lateral directions.

Abstract: Devices and methods for less invasively treating the gastrointestinal system, such as the intestinal mucosa of the small bowel. Embodiments described herein may be used to reduce caloric absorption and effectuate weight loss, for example.

Abstract: An intravascular catheter with micro spines that penetrate arterial wall to delivery drug or mechanical injury to the vessel wall inducing a “stent” like healing process in the vessel.

Abstract: A plurality of structures that resiliently attract one another are provided for implanting in a patient around a body tissue structure of the patient. For example, the body tissue structure may be the esophagus, and the plurality of structures may be implanted in an annulus around the outside of the esophagus, the annulus being substantially coaxial with the esophagus. The attraction may be between annularly adjacent ones of the structures in the annulus, and it may be provided, for example, by magnets or springs. The array of structures is preferably self-limiting with respect to the smallest area that it can encompass, and this smallest area is preferably large enough to prevent the apparatus from applying excessive pressure to tissue passing through that area.

Abstract: Implantable devices for use in a non-sterile environment of a patient's anatomy are medicated or include medication. For example, the housing of the device and/or members for securing the device to the patient's anatomy (e.g., the muscular esophageal wall) may be medicated to, among other things, prevent a rejection mechanism from being triggered, to prevent or reduce bacterial infection, or to promote tissue ingrowth. The medication may be for medicating tissue at the implant site, or for medicating some other portion of the patient's anatomy.
