This application is a continuation of U.S. application Ser. No. 11/612,980, filed on Dec. 19, 2006, which is hereby incorporated by reference. This application is related to co-pending U.S. application Ser. No. 11/612,968, filed Dec. 19, 2006, U.S. application Ser. No. 11/612,974, filed Dec. 19, 2006, and U.S. application Ser. No. 11/612,972, filed Dec. 19, 2006, all of which are hereby incorporated by reference.
In one embodiment, the instrument 1 is adapted for use with a separate delivery tool. The instrument 1, for example, may be sized and shaped for delivery through a lumen of a tube or trocar during a “sutureless” or transapical delivery technique. Likewise, the instrument 1 may be adapted for delivery through a working lumen of a delivery or guide catheter. In this embodiment, for example, the operator may first deliver a guide catheter through the patient's vasculature to the implant site and then advance the instrument 1 through the lumen. According to another embodiment, the instrument 1 includes an axial lumen extending from a proximal end to a distal end. The lumen is sized to allow introduction and advancement of the instrument 1 over a previously-implanted guide wire. In other embodiments, other techniques known in the art are used to reach the implantation site from a location outside the patient's body.
FIGS. 3-5 illustrate exemplary deployment techniques for the embodiment wherein the expandable portions IF, OF are made of a self-expandable material. In FIGS. 3-5, only the armature of the prosthetic cardiac valve prosthesis V is schematically shown (i.e., the valve leaflets are not shown). As shown, the armature includes the expandable entry (inflow) portion IF and the expandable exit (outflow) portion OF, which are connected axially by anchoring formations P. In one embodiment, as described in U.S. Publication 2006/0178740, the formations P are spaced at 120° intervals about the armature circumference and are configured to radially protrude from the prosthesis V so as to penetrate into the sinuses of Valsalva. As shown in FIGS. 3A-3E, in this configuration, the anchoring formations P protrude radially outward beyond the inflow portion IF and the outflow portion OF before and after the deployment of the heart valve prosthesis at an implantation site.
As schematically illustrated in FIGS. 7-9 (the same solution can be adopted also in the case of FIGS. 2-6, it is possible to provide a tubular sheath 30 that surrounds in the manner of a protective tunic the assembly comprised of the carrier portion 2 with the prosthetic valve V mounted therein. This with the purpose of facilitating, typically in a percutaneous implantation procedure, the advancement towards the implantation site through the tortuous paths of the vasculature of the patient without risks of undesired jamming or kinking. It will be appreciated that, for the same goal, the deployment elements 10, 20 normally exhibit a “streamlined” shape, exempt from protruding parts and/or sharp edges. This is particularly the case for the element 20 located at a distal position, which typically exhibits an olive-like shape.
4. The device of claim 1 in which the low friction material comprises Teflon™.
8. The device of claim 1 wherein the cap is coated with a low friction material.
