The invention includes a novel method and system to achieve leaflet coaptation in a cardiac valve percutaneously by creation of neochordae to prolapsing valve segments. This technique is especially useful in cases of ruptured chordae, but may be utilized in any segment of prolapsing leaflet. The technique described herein has the additional advantage of being adjustable in the beating heart. This allows tailoring of leaflet coaptation height under various loading conditions using image-guidance, such as echocardiography. This offers an additional distinct advantage over conventional open-surgery placement of artificial chordae. In traditional open surgical valve repair, chord length must be estimated in the arrested heart and may or may not be correct once the patient is weaned from cardiopulmonary bypass. The technique described below also allows for placement of multiple artificial chordae, as dictated by the patient's pathophysiology.

Devices and methods are provided for percutaneously treating atherosclerotic plaques within blood vessels. Atherosclerotic plaques cause significant morbidity and mortality by narrowing the arteries, which adversely affects blood flow, and by acting as a source for thrombi and emboli thus causing acute organ ischemia. Current treatments include open surgery with its inherent drawbacks, and stenting, which is less invasive but leaves the plaque material in the artery, which promotes restenosis. The present invention combines the advantages of both approaches. In general, the invention provides tools that enable percutaneously dissecting the plaque from the arterial wall and removing it from the body.

A method for treating shoulder subluxation using an implantable device to stimulate the axillary nerve which in turn activates sensory fibers to relieve shoulder pain and activates deltoid muscle to treat disuse atrophy and possibly augment any weakened voluntary movements. Known stimulation devices are either (1) external requiring surface electrodes or (2) implantable located directly into the deltoid muscle allowing stimulation of the proximate motor-points; each requiring relatively large stimulus currents and neither directly dealing with the pain resulting from the shoulder subluxation. In the present invention, a device is implanted via injection or open surgery proximate to the axillary nerve. Advantageously, the nerve branches into portions that stimulate the deltoid muscle and pass sensory signals. By stimulating the axillary nerve (1) a lower stimulus signal level can be used and (2) pain may be blocked while treating the atrophied deltoid muscle and augmenting weakened voluntary movements.
