A cup and a temporary insert are respectively configured to be tightly press fitted into each other along their periphery. The temporary insert includes a through hole communicating outside with a free space between the outer surface of the temporary insert and the inner surface of the cup. In the through hole can be engaged the threaded end of an impactor, for manipulating the cup when it is being set. A syringe can be engaged, enabling a liquid under pressure to be injected into the free space, thus separating the temporary insert from the cup without any risk of damaging the inner surface of the cup. Thus, the cup can be securely manipulated when it is being set without any risk of damaging the inner surface of the cup.

A fiber-based surgical implant stabilized against fraying, includes a thermally crimped flat-knitted fabric of a biocompatible, optionally biodegradable, polymer material having a glass transition temperature or other thermally induced secondary conformational mobility threshold in the temperature range of from 20? C. to +170? C. Also disclosed is a corresponding fabric and methods of producing the implant and the fabric.

Aspects of the present disclosure are directed toward providing enhanced structural support to an organ. As may be implemented in accordance with one or more embodiments, an apparatus includes structure configured and arranged to partially encircle a tubular organ, having a semi-cylindrical shape with a tapered end and blunt end of the cylinder. A gap region provides a region of the organ that is unrestricted/unsupported. Struts/lattice facilitate ingrowth of tissue, and couple the apparatus to the organ, which allows the apparatus to provide support/restrict flow in the organ without necessarily coupling to any other structure (e.g., with the majority or all of the support provided via the apparatus as coupled onto and terminating on a sidewall of the tubular organ).

During hip replacement surgery, a practitioner can attach a distal stem to a femur of the patient and can then fixedly attach a proximal body to the distal stem using a bolt. Prior to tightening, the bolt can be heated to an elevated temperature greater than average human core body temperature. The practitioner can tighten the bolt to a specified torque while the bolt is at the elevated temperature. After tightening, the bolt cools to average human core body temperature and experiences a tensile stress due to the effects of thermal expansion. The tensile stress in the bolt produces a compressive force between the distal stem and the proximal body. The compressive force can increase the attachment strength of the bolt to the distal stem and the proximal body, beyond what can be achieved by solely torquing the bolt to the specified level during surgery without first heating the bolt.

A prosthetic device for replacing at least part of one vertebral body, the prosthetic device being expandable from a fully collapsed state to a fully expanded state and comprising an upper endplate, a lower endplate and an expandable support structure extending between the two endplates, said expandable support structure being configured to displace the two endplates relative to one another along a longitudinal axis of the prosthetic device and to hold the two endplates at a minimum axial distance that corresponds to the height of at least one intervertebral disc and half a vertebral body, wherein the expandable support structure includes an anterior post and a posterior post, wherein the length (L1/L2) of each post is individually adjustable and is lockable independently from one another to hold the two endplates with an inclination of 0 to 40 relative to each other.

A fiber-based surgical implant stabilized against fraying, includes a thermally crimped flat-knitted fabric of a biocompatible, optionally biodegradable, polymer material having a glass transition temperature or other thermally induced secondary conformational mobility threshold in the temperature range of from 20?

The present invention is directed to a low profile intervertebral implant for implantation in an intervertebral disc space in-between adjacent vertebral bodies. The intervertebral implant includes a plate preferably coupled to a spacer. The plate is preferably formed from a first material and the spacer is preferably formed from a second material, the first material being different from the second material. The plate is preferably sized and configured so that the plate does not extend beyond the perimeter of the spacer. In this manner, the plate preferably does not increase the height profile of the spacer and the plate may be implanted within the intervertebral disc space in conjunction with the spacer.

An orthopedic implant comprises an articulation head comprising a bearing surface and a reverse surface and a securement disk. The securement disk comprises an attachment surface attached to at least a portion of the reverse surface of the articulation head, a securement surface opposite the attachment surface and adapted for coupling to a fixation plate secured to a bone, and at least one opening formed in the securement surface of the securement disk and adapted to accept fasteners therein. The securement disk comprises a porous material.

To increase the resistance to liquid and substance flow through a lumen of a tubular organ, a cuff comprising a flexible, mesh base member is appended to an exterior wall of the tubular organ such that it only partially surrounds the tubular organ. Ultimately, tissue ingrowth through the mesh base member integrates the cuff into the wall of the tubular organ. When the cuff is applied to the urethra of an incontinent patient, the increased resistance to flow renders the patient continent while still allowing normal voiding. The base member may also support an optional expandable component, e.g., a balloon-like element that can be selectively inflated and/or deflated to restrict the lumen of the tubular organ by a desired degree.

A method for manufacturing a prosthetic hip acetabulum includes the following steps. First, one provides an insertion cup (1) having an inner concave receiving surface (3) having an opening surface (5) contained in an opening plane (P), and having an outer annular receiving structure (6). Next, one provides an installation and positioning insert (7) having a peripheral annular attachment structure (10) shaped to engage with the receiving surface (9) of the structure (6), fitting around that structure. Next, one heats the insert (7) in order to increase its size. Next, one fits the attachment structure (10) around the receiving surface (9) of the receiving structure (6). Finally, one cools the insert (7) to room temperature to reduce its size and achieve radial tightening of the attachment structure (10) on the outer annular receiving structure (6).
