Devices, systems, and methods for delivering and deploying an implantable medical device with respect to a target site along a tissue wall by applying suction to draw the tissue wall to a delivery and deployment device, such as to a tissue-penetrating end of the delivery and deployment device. An additional implantable device may be deployed distal to the tissue wall, such as to facilitate manipulation of the distal wall. At least a portion of the first implantable medical device may be deployed with respect to the additional implantable medical device, such as within a lumen of the additional implantable medical device. The implantable medical device may shift from a delivery configuration to an expanded deployed configuration, and at least a portion of the implantable medical device may expand beyond the deployed configuration after deployment device to further resist migration of the implantable medical device from the target site.

A surgeon can secure an acetabular component to an acetabular bone. The surgeon can insert a pair of anchors through a corresponding pair of holes in the acetabular component into a corresponding pair of pilot holes drilled into the acetabular bone. Each anchor is attached to a length of suture before insertion. The surgeon can tie the sutures from the anchors together, to secure the acetabular component against the acetabular bone. The surgeon can position the tied lengths of suture in a suture channel formed in the acetabular component. The suture channel can prevent the suture from interfering with a liner that contacts the acetabular component. The surgeon can repeat as needed, using multiple pairs of anchors, multiple holes and suture channels in the acetabular component, and multiple pilot holes in the acetabular bone. The surgeon can use soft anchors or screw anchors.

Systems and methods for planning surgical procedures involving custom medical implants that can involve the selection, design and/or creation of custom medical implants and/or the selection, modification, and/or design of custom surgical procedures related to those implants. Certain embodiments allow implants to be selected, designed, created, or otherwise customized and then placed in patients using non-standard surgical techniques. The invention provides greater flexibility in implant use by allowing a surgeon to revise, create, or otherwise select surgical techniques for custom implants and, ultimately, provide better treatment in a greater variety of medical circumstances. Certain embodiments of the invention involve computer assisted surgery to provide for implant-related surgery involving non-standard surgical steps and/or implants.

An expandable fusion cage system includes an expandable fusion cage having an upper portion, a lower portion, and a hinge portion coupling the lower portion and the upper portion at their distal ends. Positioned between the upper and lower portions is an expansion element that when moved in the proximal direction causes the cage to expand at its proximal end. The system can also include inserter instruments, expandable distraction instruments, and bone funnels.

A hearing protection system including an earplug moveably displaceable in a plane covering an ear of a user from an open position to a closed position in response to a signal received from a trigger mechanism. When in the open position, the earplug is positioned adjacent to the ear of the user to allow the user to hear ambient sound at an unchanged volume. When in the closed position, the earplug is positioned over the ear of the user to at least partly block the ambient sound and allow the user to hear the ambient sound at a reduced volume that is less than the unchanged volume.

An eyeshade structure for bilirubin detection includes a body, a first detection module, and a second detection module. The body includes a bottom plate and a side wall. The side wall is connected to the bottom plate and forms an accommodating space with the bottom plate. The first detection module is arranged on the bottom plate. The second detection module is arranged on the bottom plate and is adjacent to the first detection module. The first detection module and the second detection module each include a circuit board, a light-emitting element, an inner photographing element, and an outer photographing element. The circuit board is connected to the bottom plate. The light-emitting element is electrically connected to the circuit board. The inner photographing element is electrically connected to the circuit board. The outer photographing element is electrically connected to the circuit board.

A prosthetic hip stem for use in a prosthetic hip joint. The hip stem generally includes a core having a stem portion and a neck portion, a polymer matrix layer substantially covering the stem portion of the core, and a porous metal layer substantially covering the polymer matrix layer. The polymer matrix layer connects the core and the porous metal layer, and may be injection molded therebetween. The neck portion of the hip stem has a relatively thin or slender profile which allows for an increased degree of articulating movement of the hip stem with respect to the acetabular component of a prosthetic hip joint. The neck portion of the hip stem additionally includes a version indicator element, such as a bump or a protrusion, which may be tactilely felt by a surgeon to aid the surgeon in positioning the hip stem during a minimally invasive total hip arthroplasty procedure, for example, where direct visualization of the hip stem by the surgeon may not be possible. Additionally, the core of the hip stem includes grooves, ridges, flats, dimples or other features to enhance the mechanical interconnection between the core and the polymer matrix layer.

A medical implant system is described for inhibiting infection associated with a joint prosthesis implant. An inventive system includes an implant body made of a biocompatible material which has a metal component disposed on an external surface of the implant body. A current is allowed to flow to the metal component, stimulating release of metal ions toxic to microbes, such as bacteria, protozoa, fungi, and viruses. One detailed system is completely surgically implantable in the patient such that no part of the system is external to the patient while the system is in use. In addition, externally controlled devices are provided which allow for modulation of implanted components.

A prosthetic implant includes an anterior surface, configured for at least partial contact with an underside of a patient's facial soft tissue. A posterior surface is oppositely placed to the anterior surface. The posterior surface is configured for at least partial contact with a patient's facial bony tissue when the anterior surface is in at least partial contact with the patient's facial soft tissue. An implant body is defined by the anterior and posterior surfaces and extends transversely therebetween. A selected portion of the posterior surface has a texture that mechanically differs from a texture of a majority of the anterior surface.
