A multi-lumen stent assembly (100) for deployment in a bifurcated vessel. This assembly is made of a self-expandable main body component (200) and two lumen extensions (300), able to be inserted into one of the lumens of a double-barrelled portion (208) of the main body component (200). The main body component (200) has a proximal end (201) configured to be placed toward the heart and a distal end (202). The main body component (200) has a main body portion (203), a concaved portion (206), and a transition portion (205). The main body portion (203) has a cylindrical lumen (204) of constant diameter. The concaved portion (206) has a double-barrelled portion (208) having two lumens (211). A cross-section of the transition portion (205) evolving from a circular shape to an elliptical shape towards the transition portion (205), a larger diameter of this shape being in a central plane (CP).

An apparatus including a joint spacer for treatment of a joint of a human subject. The joint spacer includes a bioresorbable stent having compressed and expanded configurations and a covering that covers an external surface of the stent. The joint spacer is configured to be inserted into a space of the joint, and is shaped, when the bioresorbable stent is in the expanded configuration, to provide mechanical support to the joint until the bioresorbable stent resorbs into a body of the subject. Treating a joint of a human subject includes inserting a joint spacer into a space of the joint while a bioresorbable stent of the joint spacer is in a compressed configuration, and transitioning the bioresorbable stent to an expanded configuration within the joint, such that the joint spacer provides mechanical support to the joint until the bioresorbable stent resorbs into a body of the subject.

Embodiments herein are generally directed to vertebral implants and implant trials for use with vertebral implant assemblies. In some embodiments, these implants and implant trials may be used in conjunction with corpectomy procedures.

Provided is an artificial vertebral fixing system. The artificial vertebral fixing system includes: an artificial vertebral main body, arranged between adjacent human physiological vertebrae; two longitudinal connecting rods, respectively arranged at two sides of spinous processes of the human physiological vertebrae; a transverse connecting screw, connected between the artificial vertebral main body and each of the longitudinal connecting rods; and a connecting portion, connected to the artificial vertebral main body; when the connecting portion is provided with a self-tapping through hole, the transverse connecting screw is formed into thread structure by self-tapping when being screwed to the self-tapping through hole; and when the connecting portion is provided with a threaded hole, the transverse connecting screw is matched with the threaded hole. According to the technical scheme of the disclosure, the problem that the artificial vertebra has a poor stability in the related technology is effectively solved.

A prosthetic system that includes a prosthetic implant acrd a support structure secured to an inner surface of a cavity of a bone is disclosed. The support structure may comprise a pair of partially hemispherical components arranged in spaced apart relationship thereby defining a channel between the pair of components.

Spinal interbody cages are provided that include a bulk interbody cage, a top face, a bottom face, pillars, and slots. The pillars are for contacting vertebral bodies. The slots are to be occupied by bone of the vertebral bodies and/or by bone of a bone graft. The spinal interbody cage has a Young's modulus of elasticity of at least 3 GPa, and has a ratio of the sum of (i) the volumes of the slots to (ii) the sum of the volumes of the pillars and the volumes of the slots of 0.40:1 to 0.90:1.

Disclosed are medical articles and processes for forming the medical articles. The medical articles may take the form of a sponge having a three-dimensional shape comprising a reservoir. In an embodiment, the sponge is formed by placing a collagen slurry, optionally further comprising a mineral, in a mold and lyophilizing the slurry. In an embodiment, an improved molding process for such medical articles comprises forcing a slurry through a mold comprising the shape of a tube having an obstruction connected to the sidewall of the tube via an arm extending from the sidewall to the obstruction.

A medical device includes a base ring configured to be implanted within a body of a patient. The base ring provides a contact surface to a vertebra. Multiple layers of multiple leveling plates are configured to equalize forces applied to the contact surface of the base ring, where at least one of the layers of the leveling plates engages an inner surface of the base ring. A layer of multiple pads is included with a top surface of the pads configured to maintain a parallel plane and a bottom surface of each of the multiple pads is configured to engage a top surface of one of the layers of the leveling plates. A cover is configured to enclose the multiple layers of the leveling plates, the layer of the multiple pads and the base ring. The cover provides a contact surface to a vertebra.

Disclosed is an expandable interbody fusion implant that is configured to have an initial configuration having a first footprint width suitable for being inserted into an intervertebral space and an expanded configuration having a second footprint width that is greater than the first footprint width. The implant may include a first body member and a second body member that is pivotally coupled to the first body member. The implant may be expanded using an inflatable balloon. The implant may be expanded bilaterally such that both body members rotate relative to the other or the implant may be expanded unilaterally such that one of the body members rotates relative to the other.
