Abstract
A removable vascular frameless filter system for capture and retrieval of emboli while allowing continuous perfusion of blood. This system is useful for any percutaneous angioplasty, stenting, thrombolysis or tissue ablation procedure. The system may minimize the incidence of stroke, myocardial infarction or other clinical complications that may be associated with these procedures.
Claims13
A removable percutaneously delivered filter system comprising:
- a delivery system, including a sheath;
- and
- a frameless filter section operatively associated with the delivery system having a proximal end and a distal end, the proximal end having at least one opening allowing fluid to flow therethrough and the distal end having a multiplicity of pores for allowing fluid to flow therethrough and capturing particles of a predetermined size, the filter section being formed from a shape memory thin film material.
A vascular filter system comprising:
- a catheter delivery system, including a sheath;
- and
- a collapsible frameless filter comprised of a biocompatible material that expands upon deployment as the sheath is retracted to oppose interior walls of a vessel, the filter having a proximal end with a plurality of openings therein, and a distal end with a plurality of openings therein, wherein blood flow assists the deployment of the filter.
