Problems solved by technology

In addition, dispersal of the drug tPA may be hindered because the blood clot causing the problem has partially or completely blocked blood flow through said vessel
CTD devices can also employ expandable baskets to mechanically open residual blood clots in vessels, but these expandable baskets generally work best in straight vessels and do not adapt well to the tortuous vasculature of venous anatomy

Abstract

The present disclosure relates to catheter systems including balloons and infusion baskets designed to be deployable in complex tubing systems for optimal treatment of blood and arterial diseases, such as blood clots, thrombus and deep vein thrombosis. The basket may include a rod having a plurality of cutouts along a portion of its length to form a plurality of bifurcations that provide support to a plurality of perforated tubes, thereby forming branches of the basket. When the longitudinal length of the basket decreases, the branches of the basket expand radially away from the longitudinal axis of the basket. The branches may also be connected to a drug delivery system such that the basket of the present disclosure allows for both mechanical and drug thrombolysis.

Description

technical field [0001] The present invention relates to mechanically deployable balloon basket catheter devices and methods for treating arterial and venous thromboembolic diseases, including pulmonary embolism and deep vein thrombosis. Background technique [0002] Conventional catheter-directed thrombolysis (CTD) involves infusion of clot-dissolving drugs, such as recombinant tissue plasminogen activator (r-tPA), via a single-lumen infusion catheter, usually Smaller than the vessel in which the single-lumen infusion catheter is placed. In addition, the drug tPA may be hindered from dispersing because the blood clot causing the problem has partially or completely blocked blood flow through said vessel. CTD devices can also employ expandable baskets to mechanically open residual blood clots in vessels, but these expandable baskets generally work best in straight vessels and do not adapt well to the tortuous vasculature of venous anatomy . For example, in the case of pulmo...
