Tissue prosthesis insertion system and method

摘要

A tissue prosthesis insertion system (80) includes a first assembly (10) comprising a plurality of nested tubes (12), one of the tubes being a carrier tube (14) which, in use, receives a component (16) of a tissue prosthesis at a distal end of the carrier tube (14). A magnetic mount (44) is carried at a proximal end of the first assembly (10). A second assembly (82) is removably attachable to the first assembly (10). An attachment device (92) is carried at a distal end of the second assembly (92), the attachment device (92) being responsive to the magnetic mount (44) of the first assembly (10), the magnetic mount (44) and the attachment device (92) carrying complementary engaging formations to facilitate hermetic sealing between the magnetic mount (44) and the attachment device (92).

1. A tissue prosthesis insertion system, comprising:
an assembly including a plurality of nested tubes, one of which is a carrier tube for carrying a component of a tissue prosthesis at its distal end and another of which is a filler tube received with clearance in the carrier tube to define a passage between the filler tube and the carrier tube; wherein, the distal end of the filler tube and the proximal end of the carrier tube are configured to facilitate engagement with each other; a withdrawing device attachable to the assembly so that, when the withdrawing device is attached and the component of the tissue prosthesis is mounted on the distal end of the carrier tube, a closed system is formed which allows the withdrawing device to be used to increase a volume of the closed system to form a low pressure region at least in the component; and a first and second magnetic mount, wherein the first magnetic mount is carried at a proximal end of the assembly and wherein the second magnetic mount is carried at a distal end of an another assembly, wherein said set of magnets and said another set of magnets are arranged relative to one another to help maintain a coupling engagement between said assembly and said another assembly and to substantially negate a need for relative rotational movement between the assembly and the another assembly during disengagement from one another, such that the another assembly is used to dispense a filler material to the assembly.
