摘要:
A saddle clamp for mounting on a bone with curved surface in a bone-fixing or spinal fusion operation, for carrying a bone-fixing member. The saddle clamp has a rigid body with at least two holes for passing fixing elements to be tightened to the bone and at least one assembly element integral with the body for attaching the bone-fixing member. The rigid body has a contact surface configured to allow at least three points of contact with the curved surface of the bone when the saddle clamp is mounted thereon, at least two of the holes passing through the contact surface at least adjacent to two of the points of contact so as to provide, upon tightening of the fixing elements, at least three spaced apart, non-collinear areas of contact and thereby firm attachment of the saddle clamp to the bone.

A manipulating device includes a hollow tube having a tube wall formed with distal cutouts that define at least one deformable member in the tube wall and proximal cutouts that define an actuator in the tube wall connected to the at least one deformable member. Movement of the actuator deforms the at least one deformable member from a first orientation to a second orientation.

The present application relates to an implantable device (104) and a method for delivering the implant for the repair and closure of annular defects and in particular, to such a device and method in which spinal annular defects are repaired with an elastic-plastic implant adept to securely seal an annular defect while providing a sufficiently compliant implant that adapts to bodily movements.

A temporarily implantable medical device is disclosed. Said device is implantable in a predetermined body portion to be treated; wherein said device comprises (a) a reversibly implantable elongated continuous strip of a predetermined shape having a biocompatible surface; said strip having a distal end within the body of a patient and a proximal end located adjacent to the subcutaneous tissue of said body portion to be treated; and, (b) a cannula having a least one exposed portion located at said subcutaneous tissue of said body portion to be treated, accommodating at least a portion of said proximal end of said strip; said cannula comprises sealing means adapted to seal said cannula.
摘要:
An implant (10) arranged as a tubular member (20) with a longitudinal axis (80). The tubular member exhibits a proximal end (100) and a distal end (110), the distal end arranged to extend to within the inner region of an annulus. Inter-annulus support members (30) are arranged radially about the tubular member, and connected proximally of the distal end, thus defining an axial support member (120) between the connection to the tubular member and the distal end. Proximal securing members are further provided arranged radially about the tubular member and removed proximally from the connection point of the inter-annulus support members. The inter-annulus support members are connected to the axial support member such that ejection forces are opposed by a concavingly curved link member between the axial support member and the inter-annulus support members.
