20100030191 | CATHETER WITH A PRE-SHAPED DISTAL TIP - Catheters having a pre-shaped tip configuration are disclosed. A catheter in accordance with an illustrative embodiment of the present invention can include an elongated tubular shaft equipped with a distal tip section having a pre-shaped tip configuration that can be used to facilitate tracking of the device through particular locations of the vasculature. The catheter may include a number of features that transition the stiffness and flexibility characteristics of the device and provide a means to radiographically visualize the catheter within the body. | 02-04-2010 |
20100145311 | CATHETER SHAFT WITH IMPROVED MANIFOLD BOND - A catheter shaft with an improved manifold bond and methods for making and using the same. The catheter shaft may include a sleeve disposed, for example, near its proximal end. The sleeve may include a first layer that is attached to the catheter shaft and a second layer to which a hub or manifold may be attached. | 06-10-2010 |
20110046522 | Ultrasound Energy Delivery Assembly - In a first embodiment, an ultrasound energy delivery assembly includes a waveguide and a catheter having a capture member. The capture member extends radially inward from an interior surface of the catheter into a lumen of the catheter and is configured to retain the enlarged distal tip so that the enlarged distal tip is temporarily prevented from moving proximally. In a second embodiment, an ultrasound energy delivery assembly includes a waveguide and a sheath covering at least a portion of the waveguide. In a third embodiment, an ultrasound energy delivery assembly includes a waveguide and a dual lumen catheter having a capture member. In a fourth embodiment, an ultrasound energy delivery assembly includes a waveguide and a catheter having a proximal waveguide lumen and a proximal guide wire lumen that merges with the proximal waveguide lumen at their respective distal ends to form a distal lumen. In a fifth embodiment, an ultrasound energy delivery assembly includes a waveguide and a catheter having a helical spring tip disposed over a distal section of the waveguide. In a sixth embodiment, an ultrasound energy delivery assembly includes a waveguide and a catheter extruded from a material such as expanded polytetrafluoroethylene. The catheter includes a braided layer having a multi-wire braided section and a single wire braided section formed from a braid wire from the multi-wire braided section. | 02-24-2011 |

20120323189 | CATHETER SHAFT WITH IMPROVED MANIFOLD BOND - A catheter shaft with an improved manifold bond and methods for making and using the same. The catheter shaft may include a sleeve disposed, for example, near its proximal end. The sleeve may include a first layer that is attached to the catheter shaft and a second layer to which a hub or manifold may be attached. | 12-20-2012 |
20130144267 | REINFORCED ELONGATE MEDICAL DEVICE AND METHOD OF MANUFACTURE - An elongate medical device includes an elongate core and a substantially flat sheet formed into a tubular body defining a longitudinal axis and disposed around at least a portion of the elongate core, where the flat sheet has a length, and where a cross-sectional thickness of the sheet varies along the length of the sheet. The tubular body has proximal and distal portions, and a cross-sectional thickness of the sheet forming the distal portion of the tubular body may be less than a cross-sectional thickness of the sheet forming the proximal portion of the tubular body. A cross-sectional thickness of the sheet forming the tubular body preferably tapers from the proximal portion to the distal portion. | 06-06-2013 |
