| 发明名称 | Vena cava filter catheter and method | ||
| 摘要 | A vena cava filter catheter includes a catheter having a lumen disposed therethrough and at least one strand of biocompatible wire. The at least one strand has a first state in which the at least one strand has an elongate geometry suitable for traversing the lumen of the catheter and a second state in which the at least one strand assumes a pre-set geometry in which the at least one strand assumes a tortuous configuration adapted to occupy a space approximating a luminal diameter of an inferior vena cava. | ||

| 主权项 | 1. A vena cava filter catheter, comprising: a. a catheter having at least one lumen disposed therethrough; b. a collapsible vena cava filter disposed about a distal portion of the catheter, such that the collapsible vena cava filter is disposed proximal from an opening associated with the at least one lumen; and c. at least one strand of biocompatible wire having a first state in which the at least one strand has an elongate geometry suitable for traversing the at least one lumen of the catheter and exiting from the opening, and having a second state in which the at least one strand assumes a pre-set geometry in which the at least one strand assumes a tortuous configuration adapted to occupy a space approximating a luminal diameter of an inferior vena cava. | ||
