Patent application numberDescriptionPublished
20080255447DIAGNOSTIC CATHETER - A diagnostic catheter having both a guidewire lumen and at least one contrast lumen is disclosed. In one embodiment, the contrast lumens allow the user to deliver contrast to a target area within the patient without removing the guidewire. Preferably, a plurality of contrast exit ports are included along the length of the catheter body to evenly and consistently distribute contrast into the blood stream, thereby providing improved visualization during radioscopy.10-16-2008
20100030114Deflectable Variable Radius Catheters - The invention provides a deflectable catheter capable of forming many variable radius spiral forms from a single, flexible, distal end section. In one aspect, the catheter employs a variable radius control wire to extend or deform a pre-formed loop structure into a three dimensional spiral-like form or geometry. The ability of a single catheter to create a multitude of shapes and sizes allows users to access to a number of anatomical areas without changing the catheter during a procedure or treatment. In another aspect, the invention encompasses methods of producing deflectable variable radius catheters, where two or more regions of the catheter having common control wires are fused or formed onto one another.02-04-2010
20100094392Expandable Sheath for Introducing an Endovascular Delivery Device into a Body - Embodiments of an expandable sheath can be used in conjunction with a catheter assembly to introduce a prosthetic device, such as a tissue heart valve, into a patient. Such embodiments can minimize trauma to the vessel by allowing for temporary expansion of a portion of the introducer sheath to accommodate the delivery apparatus, followed by a return to the original diameter once the prosthetic device passes through. Some embodiments can comprise a sheath with inner and outer tubular layers, and an intermediate tubular layer comprising a shape memory alloy. Other embodiments comprise one or more layers having one or more longitudinal notches or cuts to facilitate expansion of the sheath. Embodiments of the present expandable sheath can avoid the need for multiple insertions for the dilation of the vessel, thus offering advantages over prior art introducer sheaths.04-15-2010
