Abstract

The present invention provides devices and methods for percutaneously retrieving an embolized or malpositioned heart valve or foreign bodies from a patient's body. Several of these devices may include a catheter system with expandable and retractable baskets attached to a catheter and guidewire system. The guidewire may be inserted through the lumen of the embolized or malpositioned heart valve, capturing the valve in the baskets, and deploying a mechanism to crush the valve within the baskets. Then the crushed baskets and valve may be retrieved either from the body or to a safer location such as but not limited to the descending aorta. This system is advantageous because it does not require open surgery to retrieve the valve or embolized material.

Claims27

Dependent claims

A device, comprising:

a guide wire;
a first component, comprising:
a first hollow shaft with a first leading end and a first trailing end, wherein the leading end of the first hollow shaft is configured so that it may be advanced over the trailing end of the guide wire;
a capturing umbrella mounted on the first hollow shaft near or at the first leading end, wherein the capturing umbrella has a compressed form and an expanded form;
and
a first delivery catheter housing the first hollow shaft and the capturing umbrella, wherein the capturing umbrella is compressed when the first delivery catheter encloses the capturing umbrella, and wherein the capturing umbrella is expanded when the first delivery catheter does not enclose the capturing umbrella;
a second component, comprising:
a second hollow shaft with a second leading end and a second trailing end, wherein the first hollow shaft can be inserted into the second hollow shaft;
a crushing basket mounted on the second hollow shaft near or at the second leading end, wherein the crushing basket has a compressed form and an expanded form;
a second delivery catheter housing the second hollow shaft and the crushing basket, wherein the crushing basket is compressed when the second delivery catheter encloses the crushing basket, and wherein the crushing basket is expanded when the second delivery catheter does not enclose the crushing basket;
and
a control wire, wherein the control wire is connected to the crushing basket and is threaded through the second hollow shaft, wherein the crushing basket is compressed when the control wire is pulled, and wherein the crushing basket is expanded when the control wire is not pulled;
and
wherein the openings of the expanded capturing umbrella and the expanded crushing basket face each other.
