摘要:
A monolithic device comprising an ultra-dense stent cell pattern including a plurality of structural members that diverts the majority of blood flow without restricting blood flow completely. The method of making medical devices comprises vapor depositing an initial film onto a substrate, laser cutting a device pattern through the initial film, electropolishing the patterned device while disposed on the substrate, and releasing the patterned device from the substrate.

The invention relates to an instrument set for removing a ceramic cup insert (1) from a metal shell (2) of a hip-joint implant. For cost-effective and efficient removal of a ceramic cup insert (1) from a metal shell (2) of a hip-joint implant, an instrument set is proposed, wherein the instrument set is composed of a holding element (3), a securing device (4) connectable to the holding element (3), at least one spacer (5) and a head (6), wherein the holding element (3) has, at one of its ends, an adapter device (7) for securing the head (6), the head (6) has an adapter location (8) for securing the adapter device (7), the holding element (3) has, at its other end, a coupling device (9) for a tool for rotating the holding element (3) about its longitudinal axis (10), and the holding element (3) has an adjusting thread (11) on its circumferential surface, wherein the securing device (4) is equipped with an inner thread and can be turned on the adjusting thread (11) in the longitudinal axis (10) of the holding element (3), and at least one spacer (5) is arranged on the securing device (4) and extends parallel to the longitudinal axis (10) of the holding element (3) in the direction of the adapter device (7).

Degradation rate is suppressed to be low by suppressing the occurrence of structural defects. Provided is an implant manufacturing method including a molding step (S1) of molding a molded item by treating a raw-material piece constituted of a biodegradable metal material with plastic processing and a grain-size adjusting step (S2) of increasing metal grain size by applying a heat treatment to the molded item molded in the molding step (S1).
摘要:
An endoprosthesis, such as a stent, having anti-migration features. The endoprosthesis includes an expandable tubular framework including a plurality of strut rows and a plurality of connectors extending across interstices between adjacent strut rows and interconnecting adjacent strut rows. The strut rows have an outer diameter in an expanded state and the connectors extend radially outward beyond the outer diameter of the strut rows in the expanded state. The connectors are configured to engage a wall of a body lumen in the expanded state to inhibit migration of the endoprosthesis in the body lumen. The endoprosthesis may include a polymeric cover covering the strut rows and spanning the interstices between adjacent strut rows, while a space between the connectors and the strut rows to which the connectors are interconnected with is devoid of the polymeric cover to permit tissue ingrowth around the connectors.
摘要:
The invention relates to a medical implant device for attaching or re-attaching a flexible graft to a bone, comprising: at least a first insert comprising a synthetic osteoconductive and/or osteoinductive material, and a flexible graft, wherein the flexible graft is connected to the at least one insert, particularly prior to surgical implantation of the medical implant device.
