The apparatus includes a tissue penetrator configured to penetrate the sternum, a trigger mechanism configured to engage when the tissue penetrator contacts the sternum and a depth control mechanism operable to limit the penetration of the tissue penetrator into the sternum to a pre-selected depth.

An organ manipulator including at least one suction member or adhesive disc mounted to a compliant joint, a flexible locking arm for mounting such suction member or compliant joint, and a method for retracting and suspending an organ in a retracted position using suction (or adhesive force) so that the organ is free to move normally (e.g., to beat or undergo other limited-amplitude motion) in at least the vertical direction during both steps. In preferred embodiments, a suction member exerts suction to retract a beating heart and suspend it in a retracted position during surgery. As the retracted heart beats, the compliant joint allows it to expand and contract freely (and otherwise move naturally) at least in the vertical direction so that hemodynamic function is not compromised. The suction member conforms or can be conformed to the organ anatomy, and its inner surface is preferably smooth and lined with absorbent material to improve traction without causing trauma to the organ. The compliant joint can connect the member to an arm which is adjustably mounted to a sternal retractor or operating table. The compliant joint can be a sliding ball joint, a hinged joint, a pin sliding in a slot, a universal joint, a spring assembly, or another compliant element. In preferred embodiments, the method includes the steps of affixing a suction member to a beating heart at a position concentric with the heart's apex, and applying suction to the heart while moving the member to retract the heart such that the heart has freedom to undergo normal beating motion at least in the vertical direction during retraction.

A head support system for supporting the user's head in an at least generally upright disposition, while the user, for example, naps or sleeps or otherwise rests while traveling sitting in a seat. The head support element (1) interfaces with the underside of and, preferably, up and around the front of the chin, i.e., the mental proturberance with its central clef, and underneath the user's chin and from side-to-side of and along side the chin, i.e., the mandible body, in “face-to-face” surface engagement over a relatively large area, essentially forming a supportive cup for the chin, with a self-supporting but soft, solid block of molded, supportive material having an oblong shape with a reduced sized central portion (10) for hand grasping, with its angled, flat bottom (31) resting centrally on the central upper chest area of the user, preferably over and across the manubrium sterni area, with an anchoring strap (41) positioned, for example, around and about the back of the user's neck. The support element is at least generally “Y” shaped with a laterally enlarged base (30) when viewed from the front (FIG. 2).

A breast-supportive and breast-positioning brassiere designed to be used postoperatively by patients including obese patients and fuller-sized women who have undergone cardiothoracic surgery that requires a mid-sternal incision (sternotomy). The brassiere is also for other interventions in the thoracic region, when a comfortable and efficient individual positioning and support of the breast(s) would be desirable; an example being to prevent symmastia after breast augmentation surgery. The brassiere prevents gravitation of the breast tissue to the lateral sides, keeps the breast tissue away from the mid center, and supports the weight of the breasts. The brassiere is designed to promote less pain, less wound complications, esthetically improved wound healing, less heat generation, improved wound inspection and access for wound care, while maintaining support and dignity.

The present invention relates to a new non-invasive method for inducing angiogenesis and more particularly coronary angiogenesis wherein an operator applies localized percussion upon the upper torso proximate an ischemic myocardial region, whereby the percussive forces penetrate to cause sheer stresses to the endothelium of the coronaries which lie thereupon, and thereby cause new coronary growth by virtue of endogenous liberation of beneficial angiogenic mediators. A pair of vibratory contacts are advantageously applied to rib-spaces to either side of the sternum (or alternatively to the upper back), where-after percussion is applied at the resonance frequency of the heart / epimyocardium at a displacement amplitude of 0.1 mm-15 mm (preferably greater than 1 mm), such as to maximize an internal oscillatory effect. The system is also adaptable for cerebral and peripheral vasculature applications. Ultrasonic imaging may optionally be utilized to direct percussive therapy.

The present disclosure relates to an implantable split sternum prosthesis to facilitate closure of the chest cavity and relieve pain after sternotomy operations.

A vibratory attachment interface enabling transmission of oscillations generated by an oscillation source upon an external human body surface. The interface comprises a first contact node and a second contact node slideably mounted alongside the first contact node, wherein the contact nodes are each sized and shaped to enable seating within a human rib-space, and whereby upon forced engagement of the first contact node within a first rib-space, the second contact node automatically slides and conforms to the contour of a second differing rib-space thereby optimally nestling within the second rib-space. The attachment interface is for use in contoured application to preferably the anatomic left sternal border, third and fourth intercostal space, such as to enable and ensure an optimized vibratory transmission pathway from the chest wall to the base of the heart and coronary arteries thereupon.

The second medical device is advanced out through the distal end of the first medical device toward the third location. A sheath is positioned within the torso, the sheath spanning the distance between the first location and the second location and the distance between the second location and the third location.

The invention provides a sternum prosthesis. The sternum prosthesis comprises a plurality of sternum segments. Among the plurality of sternum segments, at least some of the sternum segments can be selectively assembled so as to form a sternum prosthesis; and the plurality of sternum segments are sequentially arranged along the extension direction of the sternum prosthesis. The sternum prosthesis is formed by assembling multiple sternum segments, and during the assembling process, the number of the sternum segments can be determined according to actual needs of a patient; and each of the sternum segments comprises a sternum block and at least one group of rib plates, wherein each group of the rib plates comprise two rib plates which are respectively arranged on two sides of one corresponding sternum block. During operation of the sternum prosthesis, rib plates of different lengths can be selected according to degree of defect; and thus, the size of the sternum prosthesis can be adjustedaccording to different needs. Therefore, the sternum prosthesis is relatively high in flexibility, and solves the problem of unable adjustment of sizes of sternum prostheses in the prior art.
