Acrylate and methacrylate monoesters and diesters having the following formula (I) ##STR1## wherein R.sub.1, R.sub.2, R.sub.3 are as defined in the specification, are disclosed. These monomers are polymerizable into hydrogel polymers which are extremely hydrophilic. These hydrogel polymers are useful in the preparation of wound dressings. These polymers form complexes with polyvalent metal ions such as Ca, Mg, Mn and Cu, and possess macrophage stimulating activity in addition to the useful properties possessed by other acrylate and methacrylate hydrogel polymers.

A tremolo plate is pivotally mounted on the guitar body, and a plurality of a combination bridge saddles and lever systems are mounted on such plate, there being one such saddle-lever system for each string of the guitar. The combination systems include saddles adapted to be pivoted by set screws to change string height. They further include levers adapted to be adjusted by screws to effect fine tuning of the strings. The heads for the fine tuning screws are captured by ears. The pivot means for the tremolo plate have a pivot axis so related to the string saddles that the intonation points of the saddles may be adjusted between positions closer to the guitar neck than is such axis, and positions farther from the guitar neck than is such axis.

A surgical device for inserting an anchor, including a handle having an actuator, an outer barrel shaft extending from the handle to a distal end and having a channel therethrough, and an outer barrel tip the distal end thereof having an elastomeric septum, a drive pin within the channel, and an implantable anchor removably coupled to the drive pin. The outer barrel shaft is coupled to an actuator for movement between a first extended position wherein the outer barrel shaft tip substantially cover the anchor, and a second retracted position where the outer barrel shaft tip do not cover the anchor. When the shaft is in the first position, the elastomeric septum of the outer barrel tip circumferentially surrounds and engages the anchor to thereby stabilize the anchor prior to deployment, and when the shaft is in the second position, the elastomeric septum does not engage the anchor.

A nanofiber-reinforced composition suited to applying to a wound site in a human body includes a carrier liquid and nanofibers dispersed therein in the carrier liquid. The viscosity of the composition is such that it is able to be applied through a tube yet adhere proximate the wound site to provide a barrier layer which assists in healing of the wound by spacing it from neighboring organs.

An alarm unit for signaling impending overflow of a urine or ostomy (waste) bag includes an external magnet held at the end of an arm. An internal ferrous armature attracts the magnet which provides flux holding a switch element open when the magnet provides at least a predetermined flux to the switch. A clamp allows the user to fasten the unit to an edge of the waste bag with the bag walls between the magnet and the armature. When the bag contents reach the magnet, fluid force of the bag contents separates the magnet and the armature, causing the switch element to close and conduct power from a power supply to a signal element. The arm may be flexible. The switch element preferably comprises a reed switch controlling an electronic power switch.

The present invention relates to nanofibers that produce therapeutic amounts of nitric oxide after a delay period, which allows time to install or implant the device into a patient. The nitric oxide release is thus localized to the area of the organism where NO dosing is indicated. The delay time is achieved by cospinning the NO-producing fiber with a fiber that tends to sequester the former's NO-producing functional groups. Fibers of the present invention may be incorporated into medical devices such as stents or other implantable medical devices to prevent the formation of adhesions or scarring in the area of the implant.

The present invention relates generally to nitric oxide releasing pharmaceutical compounds. More particularly, the present invention relates to pharmaceutical compositions that release nitric oxide under physiological conditions. In one embodiment, the present invention relates to new chemical compounds—diazeniumdiolates nitric oxide donors—that are based on ethambutol possessing physiological and biomedical activity.
