Device for transluminal implantation
First Claim
1. A device for implantation by insertion into a difficulty accessible location of a substantially tubular, radially expansible prosthesis, including in combination said radially expandable prosthesis surrounding and concentric with a flexible probe and means for maintaining said prosthesis in a radially contracted state and for releasing said expandable prosthesis in the difficulty accessible location, said means for maintaining and releasing the prosthesis comprising a hose concentrically surrounding said probe and radially surrounding the prosthesis to form a compartment therefor with one end of the hose being connected to the probe, wherein the probe has a central axial channel enabling supply of a liquid flushing medium at one end and the probe is provided with at least one radial aperture opening into a compartment of the prosthesis to enable flushing of the prosthesis compartment to remove gases therefrom before implantation of the prosthesis.

Abstract
A device for implantation by insertion into a difficulty accessible location of a substantially tubular, radially expandable prosthesis including in combination such prosthesis and concentric therewith a flexible probe provided with an arrangement for maintaining said prosthesis in a radially contracted state and for releasing same at the desired location. The arrangement includes a hose concentrically surrounding the probe and radially surrounding the prosthesis to form a compartment therefor. The probe has a central axial channel enabling supply of a liquid flushing medium at its other end and the probe is provided with at least one radial aperture opening into the prosthesis compartment to enable flushing of the prosthesis compartment to remove gases therefrom before implantation.
