| 20080306453 | Coupling wire guide and method for making same - A coupling wire guide and an improved method for bonding a mandrel to a tracking tip in a reliable and long-lasting manner are provided. The coupling wire guide includes a mandrel connected to a tracking tip. The mandrel includes a distal portion, including first and second portions integral to the mandrel, the second portion being wider than the first portion. The tracking tip includes a first tubular section and a second tubular section adapted to receive a previously introduced wire guide therein. The first tubular section is disposed over and bonded to the first and second portions to form the coupling wire guide. A coil may be attached to the distal portion upstream of the second portion. In a preferred embodiment, the second portion is a spherical structure adhesively bonded to the first tubular section. Use of a medical grade adhesive in conjunction with the second portion has been surprisingly found to increase tensile joint strength and decrease tensile joint strength variability. | 12-11-2008 |
| 20090275862 | GUIDEWIRE AND METHOD OF MAKING SAME - In at least one embodiment of the present invention, a method for making a guidewire is provided. The method comprises removing material from a distal portion of a core wire to define a distal tip extending from a proximal portion of the core wire. A collar is positioned adjacent to the distal tip about the proximal portion. | 11-05-2009 |
| 20090312670 | Wire guide having a rib for coil attachment - The present invention generally relates to a medical surgical device and specifically a wire guide for percutaneous placement within a body cavity. In one embodiment, the wire guide includes an elongated core member having a proximal stop and a distal stop and a rib positioned between the proximal stop and the distal stop. A first coil is positioned over the elongated core member and extends between the proximal stop and the rib. A second coil is positioned over the elongated core member and extends between the rib and the distal stop. | 12-17-2009 |
| 20100168619 | COMBINATION WIRE GUIDE AND METHOD OF USE THEREOF - The present embodiments generally relate to a medical surgical device and specifically a wire guide for percutaneous placement within a body cavity. The wire guide includes a multi-filar coil having an increasing pitch towards the distal end of the wire guide. Methods of using the device are also provided. | 07-01-2010 |
| 20100249654 | WIRE GUIDE - The present invention provides a wire guide ( | 09-30-2010 |
| 20110160680 | WIRE GUIDE WITH CANNULA - The present invention generally relates to a medical surgical device and specifically a wire guide for percutaneous placement within a body lumen. The wire guide includes an elongated mandrel having sufficient flexibility and kink resistance and a cannula having a stiffness greater than the mandrel stiffness for sufficient pushability. The mandrel extends through the cannula and has a portion extending distal thereto to form a distal tip of the wire guide. The wire guide can further include a slotted cannula to improve the flexibility of the wire guide at the proximal portion of the wire guide. The slots can be arranged in various patterns for increased flexibility along the longitudinal length of the cannula, as well as increased circumferential flexibility along the wire guide. The mandrel may also have a proximally tapered portion to improve the flexibility of the wire guide at the proximal portion of the wire guide. | 06-30-2011 |
