A61L 17/10

US Classification:

604514, 606228

Abstract:

Described here are devices and methods for treating one or more conditions or symptoms associated with a tonsil procedure. In some variations, a drug-releasing device may be at least partially delivered to one or more tonsillar tissues before, during, or after a tonsil procedure. In some variations, the drug-releasing device may be configured to be biodegradable. In other variations, the drug-releasing device may comprise one or more hemostatic materials or one or more adhesives. The drug-releasing device may be configured to release one or more drugs or agents, such as, for example, one or more analgesics, local anesthetics, vasoconstrictors, antibiotics, combinations thereof and the like.

International Classification:

B23P 11/00
B23P 19/02

US Classification:

29505, 29235

Abstract:

Described here are devices and methods for crimping self-expanding devices. The crimping devices may be useful for crimping a variety of different self-expanding devices (whether such devices are biodegradable or bio-durable). The crimping devices may have crimping members to engage the self-expanding device to reduce the device from an expanding configuration to an unexpanded configuration. The crimping member may comprise or include a suture, wire, ribbon, guiding hoop, pusher, prong, holding bar, balloon, jaws, combinations thereof, or the like. The crimping devices may also include or comprise a holding structure to hold the self-expanding device in an unexpanded or expanded configuration.

International Classification:

A61N 1/04
A61N 1/02
A61N 1/18
A61N 1/36

Abstract:

A peripheral nerve stimulator can be used to stimulate a peripheral nerve to treat essential tremor, Parkinson tremor, and other forms of tremor. The peripheral nerve stimulator can be either a noninvasive surface stimulator or an implanted stimulator. Stimulation can be electrical, mechanical, or chemical. Stimulation can be delivered using either an open loop system or a closed loop system with feedback.

International Classification:

A61B 8/08
A61B 90/00
A61B 8/00
A61B 5/00

Abstract:

Implantable devices for continuously monitoring vascular lumen dimensions, in particular in the inferior vena cava (IVC) for determining heart failure status of a patient. Related therapy systems as well as monitoring and therapy methods are also disclosed. Devices include active or passive marker elements placed in contact with, adhered to or injected into the vessel wall to generate or reflect signals from which lumen diameter may be determined. Disclosed devices may be fully implantable and self-contained including capabilities for wirelessly communication monitored parameters.

A61N 1/04

Abstract:

A peripheral nerve stimulator to stimulate a peripheral nerve to treat essential tremor and other movement disorders, as well as overactive bladder, cardiac dysfunction and neurotransmitter dysfunction is provided. The peripheral nerve stimulator can be a noninvasive surface stimulator to provide multi-modal optimized therapy. Stimulation can be vibrational, electromechanical, thermal, radiant, electrical, magnetic, electromagnetic, light, mechanical, chemical, thermal, ultrasonic, radiofrequency (RF), acoustic, infrared, ultraviolet, x-ray, and/or microwave. Stimulation can be delivered using an open loop system and/or a closed loop system with feedback. Stimulation can be to one site or multiple sites.
