  • Publication number: 20110015616
    Abstract: A catheter insertion system for inserting an expandable valve stent into the body of a patient and a method of implanting a valve stent. The catheter insertion system includes a catheter having a handle for manipulating a catheter tip, and enables the implantation of a valve prosthesis attached to a valve stent. The handle is configured to enable a pre-set sequence of steps to manipulate the catheter tip and sequentially release the valve stent. The catheter tip is configured to sequentially release the valve stent from a first collapsed mode to a second expanded mode.

  • Publication number: 20100292780
    Abstract: The invention relates to a device (1a-1d) for compressing a stent (100) or a stent (100) with a prosthetic heart valve affixed thereto. The invention further relates to a system as well as a method for loading a stent (100) into a medical delivery system. The device (1a-1d) according to the invention comprises a compressing mechanism (10a-10d), within which a stent (100) to be compressed can be at least partly accommodated, wherein the compressing mechanism (10a-10d) comprises externally-manipulatable clamping means (50; 70.1-70.n; 90.1-90.n; 110.1-110.n) and is designed so as to exert a compressive force in radial direction on at least parts of a stent (100) accommodated within the compressing mechanism (10a-10d) such that the cross-section of the stent (100) is reduced to a predefinable value at least at certain areas. The inventive device (1a-1d) further comprises a manipulating mechanism (40a-40d) for manipulating the at least one clamping means (50; 70.1-70.n; 90.1-90.n; 110.1-110.

  • Publication number: 20100292779
    Abstract: The invention relates to a device (1) for compressing a stent (100) with a prosthetic heart valve affixed as needed thereto. In order to achieve a compressing of the stent (100) with a prosthetic heart valve affixed as needed thereto to a diameter enabling it to be received in a catheter tip of a medical delivery system without running the risk of damaging the stent (100) or the prosthetic heart valve affixed as needed thereto during the compressing of the stent (100), the device (1) comprises a compressing mechanism (10) within which a stent (100) to be compressed can be at least partly accommodated, wherein the compressing mechanism (10) is designed so as to exert a defined compressive force in radial direction on at least parts of a stent (100) at least partly accommodated in the compressing mechanism (10) such that the cross-section of the stent (100) is reduced to a predefinable value at least at certain areas.
