An implantable rod can be bent three-dimensionally in an automated system, which is especially useful for pre-surgical formation of implantable spinal rods. When local and/or global feedback processing accompanies a series of shaping steps automatically imposed on a rod or other article being shaped into three-dimensional form, formation time may be expedited compared to manual creation, and shapes difficult or impractical to create manually may be constructed simply.

Provided herein are systems, devices and methods for the correction of spinal deformities with the use one or more implantable rods configured to apply a corrective force to the spine. Methods of minimally invasive implantation of a corrective system are provided, such as where the corrective system is attached only to the spinous process of one or more vertebral bodies. Various corrective systems as well as components thereof are also provided.

A distal component for an interphalangeal prosthesis suitable for insertion into a proximal end of a distal phalangeal bone includes a stem portion shaped to be received within a surgically prepared bore in the proximal end of the distal bone. A head portion has an under-surface and an upper-surface, the under-surface of which in use will bear on the bone into which the stem is implanted.

An implantable graft-assembly has a) a radially expandable substantially tubular frame (e.g., a stent); and b) a graft having an at least partially curved periphery, such as an oval or circular graft. Also provided are methods of treating aneurysms using such graft assemblies, methods of making the graft assemblies, use of sheets of materials for making the graft assemblies, and methods of mounting graft-assemblies having partial covers such as grafts on delivery devices such as delivery catheters or inside delivery sheaths.

An implantable stimulation lead for introduction into the brain or other anatomical target in a human body comprises a distal electrode terminal, a proximal connector terminal, and a connecting conductor cable. The led construction enables stylet means to bypass the cable and the connector terminal. A slotted cannula allows the cable and the connector terminal to be decoupled from the lead introduction tools. This enables a substantial stylet means and allows the cable and the connector terminal to be optimized without constraints of the lead introduction tools. The overall length of the lead is minimized and the conductor cable and the connector can be non-iso-diametric. A method of terminating conductors to electrodes using inserts is suitable for very fine wires and stranded conductors. The disclosed leads and accessories are applicable to stimulation leads, sensing leads, or any other lead that may be implanted with or without a stereotactic localization system.

A heart assist system having an implantable pump conveying blood between two vascular locations and an extracorporeal system providing power and control signals to the pump. The system also includes a communication link having an implantable portion coupled to the implantable pump, an extracorporeal portion coupled to the extracorporeal system and an isolation portion between the implantable portion and the extracorporeal portion that minimizes the transmission of movement and forces from the extracorporeal portion to the implantable portion.

An injectable or implantable rod-shaped formulation is disclosed for delivery of osteogenic proteins. The formulation comprises hyaluronic acid derivatives and osteogenic proteins, and optional excipients and active ingredients such as a bone resorption inhibitor. Methods of making injectable rod-shaped pharmaceutical compositions and methods of using the osteogenic compositions to treat osteoporotic and/or osteopenic bone are also disclosed.

A percutaneous cross connector system for use with implantation rods comprising a rod attachment device comprising a first jaw portion and a second jaw portion. The first jaw portion comprises a first concave surface to engage with a surface of a rod, a first biasing member, and a first pivoting mechanism. The second jaw portion comprises a second concave surface to engage with an opposite surface of the rod from the first jaw portion, a second pivoting mechanism, a second biasing surface, and a second locking surface. The first and second jaw portions can be mated so that the first and second concave surfaces are positioned on opposite sides of the rod, the first and second pivoting mechanisms are aligned to pivot on a common axis, and the first biasing member is engaged against the second biasing surface to drive the second jaw portion against the rod.

An implant insertion instrument, and an implant are provided. The instrument includes a handle, a sleeve mounted to a distal end of the handle, and an implant rod disposed within the sleeve. The implant rod includes a gripper disposed on a distal end of the implant rod. The gripper has a first prong spaced apart from a second prong, the second prong being longer than the first prong. The implant includes an implant body, the implant body having a convex surface opposite a concave surface wherein an outer surface of the implant is continuous so as to prevent bone growth within the implant. Accordingly, the instrument facilitates the engagement of the implant by a simple push of the sleeve. Further, the implant has a continuous surface so as to inhibit bone growth and facilitate removal of the implant from the surgical site.

The invention provides an implantation and recovery device for an adsorption wire by surface geochemical exploration. The implantation and recovery device comprises a drilling machine fixing device, a drilling machine lifting device, a drilling machine, a drilling rod, an implantation rod and a signal device, wherein the drilling machine consists of a drilling machine main body, clamping rods, a remote controller and lower inserting feet; a pin hole is formed at the side part of the top end of the drilling rod; clamping holes correspond to the clamping rods; a circular swinging iron sheet is arranged in the center of the bottom of the drilling rod; a swinging magnet is arranged in the drilling rod, in a circular ring shape, and fixed at the bottom of the drilling rod; an opening of the swinging iron sheet faces outwards; the implantation rod is located in the center of the interior of the drilling rod; a pin hole is formed at the side part of the top end of the implantation rod; a gear groove is formed in the implantation rod; a net structure is arranged outside the implantation rod, and provided with a large opening at the middle lower part of the implantation rod; the adsorption wire is arranged at the bottom of the implantation rod; the exterior of the implantation rod is surrounded by a dismountable large-opening protective net; and the signal device comprises a signal transmitting device, a signal positioning device and a signal lamp. In addition, the invention further provides an implantation and recovery method for the adsorption wire by the surface geochemical exploration.

Implementations described and claimed herein provide an implantable lead optimized for an implant environment and methods of manufacturing such implantable leads. The implantable lead includes an insulation layer having one or more transitions along a length of the insulation layer from a proximal end to a distal end. Each of the transitions is a seamless change from a section of the insulation layer having a set of performance characteristics to another section of the insulation layer having a different set of performance characteristics.
