Simplicio Velilla

Devices for insertion into an atrial appendage of stasis reducing components such as mesh members, chemical bonding agents or expandable anchors are disclosed.

An electrode support structure comprises a guide body having at its distal end a flexible spline leg. The spline leg is flexed to define an arcuate shape to facilitate intimate contact against tissue. An electrode element is carried by the spline leg for movement along its axis. The structure includes a control element coupled to the electrode element. The control element remotely imparts force to move the electrode element along the axis of the spline leg. Therefore, in use, the physician can cause the electrode element to travel along a path that the spline leg defines, without otherwise changing the location of the guide body.

Systems and associated methods form larger and deeper lesion patterns by shaping a support body with multiple electrodes in ways that increase the density of the electrodes per given tissue area. The support body can carry either elongated, continuous electrodes or arrays of non-contiguous, segmented electrodes.

Systems and methods for forming large lesions in body tissue using curvilinear electrode elements

Systems and associated methods position arrays of multiple emitters of ablating energy in straight or curvilinear positions in contact with tissue to form elongated lesion patterns. The elongated lesion patterns can continuous or interrupted, depending upon the orientation of the energy emitters.

A cardiac ablation catheter has an energy emitting surface for thermally destroying tissue. The surface normally presents a compact, low profile for introduction into the heart. Once introduced, the energy emitting surface can be significantly enlarged. The enlarged surface emits ablation energy sufficient to create a lesion that is significantly larger in terms of volume and geometry than the surface's initial low profile would provide.

Systems and methods supply ablation energy to an electrode in contact with tissue to form a tissue-electrode interface. The system and methods sense, simultaneously with ablation, at least two tissue temperature conditions using at least two tissue temperature sensing elements which are held within a carrier that is substantially isolated from thermal conductive contact with the electrode. The carrier holds the tissue temperature sensing elements in a spaced apart relationship in thermal conductive contact with tissue at different depths beneath the tissue-electrode interface. The systems and methods control the supply of ablation energy to the electrode based, at least in part, upon temperatures sensed by the tissue temperature sensing elements.

The present invention relates to a multiple valve single port manifold for use with a multiple lumen catheter. The inventive manifolds comprise a conduit with an entry port; a plurality of means for connecting the conduit to a plurality of catheter lumens, such that each lumen is capable of being in fluid communication with the entry port; and a plurality of means for controlling access from the conduit to the plurality of catheter lumens, such that each controlling means independently regulates access from the conduit to its corresponding catheter lumen. Because each catheter lumen is independently accessible from the same manifold port, the inventive devices are useful in any medical context where a need exists to independently control access to spatially proximal sites within a patient's passageway. For example, practice of the present invention allows a fluid to be delivered to any combination of spatially proximal vessel sites, or more typically, allows multiple balloons mounted on a catheter to be independently inflated and/or deflated during angioplasty procedures.
