| 20100274189 | BALLOON CATHETER AND METHOD OF MANUFACTURE OF THE SAME - A balloon catheter, for use with an introducer, includes an outer catheter, a telescopically disposed resilient inner catheter and a high-aspect, distal, inflatable balloon having one end of the balloon coupled to the inner catheter and an opposing end of the balloon coupled to the outer catheter. The balloon is joined at its corresponding ends to the corresponding inner and outer catheters, so that the balloon, when inflated, buckles and twists the inner catheter inside the outer catheter. This creates forces which automatically return the balloon to the wrapped configuration when deflated. The balloon diameter to length aspect ratio is equal to or greater than 1. The balloon is wrapped around the self adjusting inner catheter extended from the outer catheter when the balloon is deflated so that the outer and inner catheters with the deflated balloon fit and are disposable through the introducer. | 10-28-2010 |
| 20090187147 | APPARATUS AND METHOD FOR ACHIEVING MICROPUNCTURE - A method comprises the steps of inserting a microneedle or micropuncture device into a body cavity to achieve a micropuncture into the cavity while reducing tissue trauma at a puncture site. A stepped or tapered guidewire having a reduced diameter distal portion is telescopically disposed through the inner diameter of the microneedle or Micropuncture device. A proximal portion of the guidewire has a diameter larger than the inner diameter of the microneedle or Micropuncture device and extends to a proximal end of the guidewire. The proximal portion is adapted for guiding a larger diameter instrument into and through the vascular system. The microneedle or micropuncture device is withdrawn from the micropuncture while leaving the distal portion of the guidewire extending through the micropuncture. The microneedle or micropuncture device is removed from the guidewire without removing the microneedle or Micropuncture device over the proximal end of the guidewire. As a result, tissue trauma at the puncture site is substantially reduced. | 07-23-2009 |
| 20090182281 | APPARATUS, SYSTEM, AND METHOD OF SHIELDING THE SHARP TIP OF A TRANSSEPTAL GUIDEWIRE - Apparatus, system, and methods for introducing a sharp tip of a transseptal guidewire through a hub of a transseptal needle and into a lumen of a transseptal needle are provided. The apparatus includes a holder that contains the transseptal guidewire and a shield coupled to the holder. The shield has a wall defining a lumen that accommodates the sharp tip of the transseptal guidewire. The cross-sectional shape of the wall is substantially constant along at least a portion of its length and sized to fit within the lumen of the transseptal needle, thereby inhibiting contact between the sharp tip of the transseptal guidewire and the hub of the transseptal needle when the wall of the shield is positioned to extend into the lumen of the transseptal needle. The lumen of the shield has a substantially constant cross-sectional area along at least a portion of its length and an outer surface of the wall of the shield is cylindrical along the same length. | 07-16-2009 |
| 20090105742 | TRANSSEPTAL GUIDEWIRE - A transseptal guidewire and methods for perforating the intra-atrial septum of the heart are disclosed. The transseptal guidewire has an elongated body with an end section and a tapered distal section. At least a portion of the end section has a first dimension in a first direction transverse to a longitudinal axis of the elongated body. The first dimension is larger than a second dimension of the portion of the end section in a second direction transverse to the longitudinal axis. | 04-23-2009 |
