The present invention provides a design method and apparatus for a handle or grip providing a shape and structure that fills various regions of the hand except a region in an area over the underlying carpal tunnel. Such design method and apparatus provides for various supports and handles for use by a hand. In particular, the apparatus includes a generally boot-shaped body or portions thereof. The body or body portions include a radial section, an ulnar section and middle section. Furthermore the body has a distal (frontal) finger side, proximal (back) side, palmar side and a thumb side. The body also has radial and ulnar sides. These portions are shaped to engage the various corresponding regions of the inner surface of the hand. These sections and sides forming the body can be divided and used separately for individual applications of the present invention.

A retractor instrument for minimally invasive surgery may include a housing with a longitudinal axis, an arm extending from a distal end of the housing, and an actuation mechanism, wherein actuation of the actuation mechanism causes radial expansion of the arm relative to the longitudinal axis. The device may be adapted for use with an endoscope or arthroscope or may be an integral part of one such scope. A method of performing surgery in constrained areas within the body is also included and may be applicable to the carpal tunnel of a wrist and palm or the cubital tunnel of an elbow.

The present invention provides a design method and apparatus for a handle providing a shape and structure that fills various regions of the hand except a region in an area over the underlying carpal tunnel. Such design method and apparatus provides for various handles for use by a hand. In particular, the apparatus includes a generally Y-shaped configuration, such as for a forceps / tweezers handle with a working end. The handle can include a radial section, an ulnar section and middle section. The handle also can have a radial arm, an ulnar arm and distal leg, with an ulnar end and a radial end for engaging a portion of the hand.

The present application discloses an open air wrist brace for use in supporting the wrist in an anatomically neutral position, or in a position that permits therapeutically-useful extension, without increasing pressure on the carpal tunnel, median nerve or flexor tendons in the forearm.

An apparatus for use with a hand includes a handle body with an ulnar section for engaging the palmar arch of the hand, the ulnar section having a distal ulnar side for receiving the small finger of the hand and having a palmar ulnar side, the palmar ulnar side having a surface for engaging a portion of the palmar surface of the hand so as to position the end of the small finger in substantial alignment with the ends of the middle finger and the ring finger and to position the handle within the hand without engaging a surface of the hand located over the carpal tunnel; and a compressible and resilient proximal-side surface supported by a supporting mechanism so as to maintain a proximal-side desirable shape different from a shape of the proximal side of the handle body.

An endoscopic tool utilizes a fiber optic system for illuminating and imaging ligaments or other tissue which are to be cut. Illumination and imaging is performed above a lateral opening at the distal end of a probe that is inserted into an incision point. Preferably, a two edged blade which can be moved in both the distal to proximal direction and the proximal to distal direction is selectively deployable from of the lateral opening at the distal end of the probe. The endoscopic tool is small in size, and preferably includes a pencil grip with a button actuator for deploying the two edged cutting blade. A wire actuator that fits into a slot in the bottom of the deployable blade, can be nested with the fiber optic cable such that the cross sectional area of the probe is reduced. Alternatively, a tube concentric with the fiber optic cable can be used as the mechanism for actuating the blade or other device. The surgeon can observe cutting of the ligament or other tissue as he moves the endoscopic tool in either or both the forward or reverse direction on a display screen which is operatively connected to the fiber optic system. A retractor can be used in conjunction with the endoscopic tool to lift tissue where dissection is desired, and to function as a guide for the blade.

A first carpometacarpal joint implant. One embodiment of the invention includes proximal and distal components. The proximal component includes a fixation portion for attachment to one or more elements of a patient's distal carpal row, a ball-type joint portion cantilevered off the fixation portion, and a skid having a concave surface opposite the ball-type joint for engaging a patient's scaphoid bone. The distal component has a fixation portion for attachment to a patient's thumb metacarpal, and a socket-type joint portion that cooperates with the ball-type joint portion of the proximal component.

Described herein are methods, systems and devices for cutting a ligament of a patient. In some embodiments, the method may include the steps of advancing a cannulated probe into a patient, advancing the distal end of the tissue modification device assembly posteriorly through the skin of the patient such that it exits the patient, exposing at least one tissue modification element of the tissue modification device assembly, and reciprocating at least a portion of the tissue modification device assembly by alternately pulling on proximal and distal portions of the tissue modification device assembly to draw the at least one tissue modification element across the ligament to cut the ligament, in some embodiments, the system may include a probe, a tissue modification device, and a sheath. The tissue modification device may include a proximal handle, at least one tissue modification element configured cut ligament, and a sharp distal tip.

Methods for treatment by collagenase injections are provided, which are effective in dissolving and lysing a collagenase septa network to treat carpal tunnel, plantar fasciitis and lateral epicondylitis conditions. The methods treat such conditions by injecting or otherwise delivering purified collagenase to the afflicted region of the patient, as well as use of collagenase for manufacture of a medicament for such conditions.

A parallel handle, parallel handle system and method for designing parallel handles for a hand for use with tools or control mechanisms, that includes a handle having a radial section having a side for receiving the thumb and having a side for receiving the index finger, the radial section having a surface for engaging a portion of the palmar surface of the hand, a middle section having a side for receiving at least a portion of the middle finger and at least a portion of the ring finger and having a surface that avoids placing undue pressure on a surface of the hand located over the carpal tunnel, and an ulnar section having a side for receiving the small finger and having a surface for engaging a portion of the palmar surface of the hand so as to position the end of the small finger.

Method and system for non-invasive determination of a pressure characteristic associated with carpal tunnel (CT) region of a subject. Speed of a shear wave induced in the tissue of the subject and propagating through the CT region is measured at least once. The pressure characteristic is substantially proportional to determined speed.
