A prosthetic elbow for replacing an elbow of a dog or a human to restore normal, pain-free joint function. The elbow includes a humeral component for attachment to a humerus and a radioulnar component for attachment to an ulna. The humeral component includes a generally cylindric spool having a contoured external surface defining a first articular surface. The radioulnar component has a generally U-shaped contour with an inner peripheral surface defining a second articular surface sized and shaped for engagement with the first articular surface. Positional guides provide for implantation at precise locations.

A metallic inverted L-shaped implant is used to resurface the superior facet of the inferior vertebrae limited to the facet joints located on the spine, Occiput-C1 through L5-S1. The metallic implant is highly polished on its exterior and textured on its interior surface. It is mechanically crimped in place without the use of cement or pedicle screws. Permanent fixation occurs when bone in-grows onto a rough, porous surface on the inside of the implant. The implant employed in a hemi-arthroplasty method resurfaces half of the facet joint to provide for smooth, pain free joint articulation in deteriorated or diseased spinal facet joints without the need for major surgery or rehabilitation at considerably less risk to the patient.

An aqueous solution of local anesthetic is instilled into the urinary bladder in sufficient concentration with the addition of an alkalinizing agent such as sodium bicarbonate to elevate the intra-vesical pH to approximately 8.0. The combination is left in situ in the bladder for at least fifteen minutes to allow time for absorption of the base form of the local anesthetic. This method provides safe and effective topical anesthesia to allow pain-free cystoscopic biopsy and cautery of bladder lesions such as bladder cancer, and provides a means to treat inflammatory conditions of the bladder such as chronic interstitial cystitis and acute bacterial cystitis.

A method enabling relatively pain-free wound debridement is provided. The method entails double-delivering ultrasound to the wound and dissecting material to be debrided with a cutting edge. Delivering ultrasound energy via a coupling medium to an area of the wound within the vicinity of the material to be debrided and exposing the material to be debrided to ultrasound vibrations as to induce vibrations about the point of dissection, the double-delivery of ultrasound elicits an effect allowing for relatively pain-free debridement. While the effect elicited by the double-delivery is in place, the material to be debrided is dissected with a cutting edge.

A restraint, reposition, traction, and exercise device treats acute or chronic mechanical pain, particularly back, neck, hip, pelvis, shoulder, knees, and/or leg pain, and restores and/or increases range of motion in suitable users. The device may include two or more movable support structures and two or more restraints, such as straps. The restraints may be incrementally adjustable to stabilize two or more portions of a person's body, such as the back and/or pelvic regions, against the support structures in any number of three-dimensional orientations that produce a substantially pain-free position. The support structures may be moved apart to apply spinal traction to the portions of the person's body between the restraints. Exercises may be performed while in a substantially pain-free position before, during, or after spinal traction is applied. The user may reposition and restrain herself/himself in another substantially pain-free position and then re-apply spinal traction and/or perform further exercises.

A restraint and exercise device is provided to treat acute or chronic mechanical pain, particularly lumbopelvic and/or leg pain, and to restore and/or increase range of motion in suitable users. The device is particularly useful during exercise. The device may contain a restraint, such as two straps, connected to a support structure. The straps help restrain a portion of a person's body such as the pelvic region. The portion of the person's body may be restrained in a substantially pain-free position so as to reduce the pain that would otherwise be felt during exercise.

Relatively pain free vaginal dilation is obtained by inserting into the vaginal canal a variable rigidity vaginal dilator having an inflatable balloon, in a manner that avoids insertion into the urethra. Air is introduced into the balloon. When the patient has gained confidence in the pain free use of the dilator, the balloon is deflated to remove the air and water is introduced into the balloon to expand it so that it contacts the vaginal canal and exerts a pressure thereon. This contact is maintained for a period of up to about 15 minutes. The pressure and/or contact time is stepwise sequentially increased to a maximum of about 12 atmospheres and a contact time of up to about 45 minutes, in accordance with a regimen and instructions established by the patient's healthcare provider and tailored to the patient's specific needs. A preferred embodiment of the dilator and a kit employing same, useful in the method of the invention, are disclosed.

A device and method are outlined for the manual or automated insertion and extraction of a miniaturized implantable biosensor underneath the skin. System comprises injection and extraction module that is in operable communication with a positioning and tracking module, microprocessor and data acquisition units. The positioning and tracking module utilizes light- or magnetic field-sensing arrays to provide spatial (x, y) position, depth (z) and rotational (□) state of the miniaturized implant. This is fed to the injection and extraction module that lines up a catheter. For extraction, the catheter is actively guided using sensing arrays to extract the biosensor. This system has also provisions to excise fibrosis tissue around the implant. This tool is operated in a manual or automatic mode to facilitate pain-free injection and extraction of a miniaturized biosensor with minimal trauma.

A vein stripping device for removal of varicose veins including a base body and a guide cable, which is connectable to the base body and insertable into a varicose vein. Attached to the base body is at least one lens which receives incident optical light to generate light energy for cutting and severing the varicose vein. The surgery is substantially pain-free and ensures a blood-dry lumen or stripping-channel.

A humane, pain-free method of animal training includes interrupting the animal's vision to deliver a training stimulus. A lens having an electro-optic shutter is placed within the animal's field of vision. The shutter is open and does not obstruct or interrupt the animal's vision while the animal exhibits desirable behavior. The shutter is closed and interrupts the animal's vision to deliver a training stimulus as needed. The closed shutter is re-opened to remove the training stimulus and continue training.
