Embodiment Construction

[0063] Figure 1A-Figure 1F , according to some embodiments of the present invention, illustrates device 100, eg, a surgical tubing system. The device 100 is formed from the inside to the outside with, for example, an inner tube 101, an intermediate tube 102, and an overtube 103, the tubes 101-103 being generally telescoping devices relative to each other, and being, for example, , the axes extending longitudinally are concentric and coaxial.

[0064] The device 100 is shown with a delivery catheter 105 extending through the inner tube 101 and is shown supporting instrumentation, such as a stent supporting a valve 110 (hereinafter "valve 110"). The stent support valve 110 is formed from a stent 110a and a valve 110b for heart implantation, as in Figure 3E shown in detail. Alternatively, the valve 110 may be just a valve without a bracket support.

[0065] As used herein, a "tube" is any type of surgical tube, catheter, instrument, device or cannula having a cylindrical ou...

Abstract

A filter system comprises an expandable filter, with a first end of the filter attached to an end of a first tube, and a second end of the filter attached to an end of a second tube. The tubes are arranged telescopically with respect to each other such that telescopic movement of the first and second tubes with respect to each other causes the filter to move between a first collapsed, position and a second expanded position, where the filter extends outwardly. The filter may be a folded-over member, when in the expanded position, or a spiraling member.

Description

【Technical field】 [0001] This patent application is related to and claims priority from commonly owned U.S. Provisional Patent Application Serial No. 61 / 910,065, entitled: Filtration and Encapsulation Apparatus and Methods of Use, filed November 28, 2013, said Provisional Patent The content of the application is incorporated by reference in its entirety into this application. 【Background technique】 [0002] The present invention relates to a filter device for use in a surgical environment inside the body. During surgical procedures, such as cardiovascular procedures, eg, valve replacement, there is a possibility that particles and tissue material can escape from the host tissue and enter the bloodstream. If the particle enters the bloodstream, it can clog blood vessels, for example, in the brain, causing a stroke, or causing an embolism in the lungs, kidneys or intestines, all disastrous conditions. It is believed here that this may occur in up to 15% of cardiovascular sur...
