Visualization apparatus for transseptal access
ActiveUS20070293724A1Easy to identify visuallyDifficult to identifyUltrasonic/sonic/infrasonic diagnosticsSurgerySeptal wallVia device
Visualization apparatus and methods for transseptal access are described herein where intravascular access across a septal wall is facilitated via devices which provide for direct visual viewing of tissue area. Such a system may include a deployment catheter and an attached imaging hood deployable into an expanded configuration. In use, the imaging hood is placed against or adjacent to the tissue to be imaged in a body lumen that is normally filled with an opaque bodily fluid such as blood. A translucent or transparent fluid can be pumped into the imaging hood until the fluid displaces any blood leaving a clear region of tissue to be imaged via an imaging element in the deployment catheter. Any number of therapeutic tools or a guidewire can be passed through the catheter and into the imaging hood for crossing the septal wall and passing the guidewire or instruments therethrough.

A medical device (1210) comprises a generally cylindrical treatment element (1220) for location between a pair of valve leaflets (1212) situated between an atrium (1214) and a ventricle (1216) of a heart. The treatment element (1220) supports the valve leaflets (1212) at the region of co-aptation of the valve leaflets (1212) and occludes the valve opening to resist fluid flow in the retrograde direction through the valve opening. The device (1210) comprises a support (1222) to support the treatment element (1210) at the region of co-aptation of the valve leaflets (1212). The support has an anchor (1224) and a tether (1226), the tether (1226) being provided at the end of a guide wire (1228) which is initially utilised in the percutaneous insertion of the treatment element (1220). The anchor (1224) is secured, in use, to a septal wall (1230), while the guide wire (1228) exits the atrium (1214) through a vein adjacent a rear wall (1224) thereof. The treatment element (1220) includes a remotely actuatable clamp therein, in order to allow the treatment element (1220) to be secured to the guide wire (1228) or the tether (1226).

Catheter control systems
ActiveUS20100004633A1Guaranteed simulation effectEfficiently controlling the hood positionSurgeryEndoscopesControl systemSeptal wall
Catheter control systems which facilitate the tracking of an angle of deflection of a catheter distal end can be used for any number of procedures where catheter orientation relative to the body is desirable, e.g., in transseptal access procedures where an accurate angle of puncture of the septal wall is desirable. Such control systems may comprise a steerable handle which is oriented relative to the catheter steerable section to provide for consistent catheter articulation upon corresponding manipulation of the steering ring. Another variation may utilize an orientation indicator to track the deflectable distal end. For instance, an orientation marker as visualized through an imaging hood on the distal end may correspond to identical orientation markers on the control handle such that articulation of a steering mechanism in a direction relative to the orientation markers deflects the catheter distal end in a corresponding direction relative to the visualized orientation markers.

Over-the-wire cardiac implant delivery system for treatment of chf and other conditions
Medical devices, systems, and methods reduce the distance between two locations in tissue in a minimally invasive manner, often for treatment of congestive heart failure. In one embodiment, an anchor of an implant system may, when the implant system is fully deployed, reside within the right ventricle in engagement with the ventricular septum. A tension member may extend from that anchor through the septum and an exterior wall of the left ventricle to a second anchor disposed along an epicardial surface of the heart. Deployment of the anchor within the right ventricle may be performed by inserting a guidewire through the septal wall into the right ventricle. The anchor may be inserted into the right ventricle over the guidewire and through a lumen of a delivery catheter. Delivering the anchor over the guidewire may provide improved control in the delivery and placement of the anchor within the right ventricle.
