Implants for creating connections to tissue parts, in particular to skeletal parts, as well as device and method for implantation thereof
First Claim
1. A method for locating a material having thermoplastic properties in pores of bone tissue in a human or animal body, the method comprising the steps of:
- providing a pin comprising the material having thermoplastic properties and a core, wherein the core comprises a distal end and a proximal end and a circumferential surface therebetween, wherein the material having thermoplastic properties is arranged on the circumferential surface of the core constituting an outer region of the pin, and wherein the material having thermoplastic properties is liquefiable with the aid of mechanical vibration energy,providing an opening in the bone tissue, the opening being adapted to the pin,positioning the pin at least partly in the opening,impinging the outer region of the positioned pin with the mechanical vibration energy for a time sufficient for liquefying at least part of the material having thermoplastic properties, and, in a liquefied state, pressing it into the pores of the bone tissue surrounding the opening,stopping the vibration energy for a time sufficient for re-solidification of the liquefied material, and,after the step of stopping, removing the core.

Abstract
A method for locating a material having thermoplastic properties in pores of bone tissue includes providing a pin having the material having thermoplastic properties and a core, wherein the material having thermoplastic properties is arranged on the circumferential surface of the core constituting an outer region of the pin. An opening is provided in the bone tissue, and the pin is positioned at least partly in the opening. The outer region of the pin is then impinged with mechanical vibration energy for a time sufficient for liquefying at least part of the material having thermoplastic properties, and, in a liquefied state, pressing it into the pores of the bone tissue surrounding the opening. The vibration energy is stopped for a time sufficient for re-solidification of the liquefied material, and then the core is removed.

10. A method for fastening a first and a second object relative to bone tissue in a human or animal body with the aid of a material having thermoplastic properties and being liquefiable by application of mechanical vibration energy, the method comprising the steps of:
-
providing the first and second objects, wherein the first object comprises a first surface portion of a first material having thermoplastic properties and at least one of the first and second objects comprises a second surface region of a second material having thermoplastic properties, positioning the first and the second objects relative to each other and relative to the bone tissue such that the first surface region faces the bone tissue and the second surface region faces a third surface region of the other one of the first and second objects, impinging the first or the second object with the mechanical vibration energy for a time sufficient for liquefying at least parts of the first and second surface portions while bringing the first surface portion into contact with the bone tissue and the second surface portion into contact with the third surface portion, stopping the mechanical vibration energy for a time sufficient for re-solidification of the liquefied material while keeping the first surface portion in contact with the bone tissue and the second surface portion in contact with the third surface portion, wherein, in the step of impinging and in the step of stopping, connections are established between the first surface portion and the bone tissue and between the second surface portion and the third surface portion. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)
