Delivery systems for expandable elements, such as stents or scaffolds having spikes, flails, or other protruding features for penetrating target tissue and/or delivering drugs within a human patient are described along with associated methods for using such systems. The delivery systems can be provided with a stent that is positioned over an inflatable balloon for expansion and delivery of the stent to a target delivery location. By positioning the stent over and about the inflatable balloon, the stent is ready to be expanded by the balloon immediately upon unsheathing with respect to the outer shaft. Additionally or alternatively, a stent can be positioned in an axially offset arrangement with respect to a balloon to reduce the need for space required by overlapping components.

Delivery systems for stents having protruding features

An intravascular emboli capture and retrieval system for intravascular embolism protection and embolism removal or maceration. Guidewire mounted proximally and distally located multiple opening filters are deployed within the vasculature and used to part, divide and macerate embolic debris and to capture such embolic debris within the confines thereof. A deployable flexible preformed memory shaped capture sleeve is alternatively used to collapse one or more filters and embolic debris therein for subsequent proximal withdrawal from the vasculature.

Intravascular guidewire filter system for pulmonary embolism protection and embolism removal or maceration

The general purpose of the present invention is to provide a catheter for removal of an organized embolic thrombus, preferably in conjunction with a distal occlusion balloon guidewire. The present invention consists of three main components including a capture/delivery sheath, a capture sleeve of mesh attached to a tube and a grasping mechanism attached to another tube which is central to the other components. Operative structures in the form of manifolds are connected to such components in order to manipulate and control the relative positions of the capture/delivery sheath, the capture sleeve and the grasping mechanism. An embolic thrombus is engaged by the deployable automatically expanding serrated fingers of a grasping mechanism in combination with a deployable automatically expanding mesh capture sleeve. The capture/delivery sheath is maneuvered to cause compression of the serrated fingers and of the mesh capture sleeve for subsequent removal of the embolic thrombus.

Catheter for removal of an organized embolic thrombus

A thrombectomy catheter system with occluder and method of using same for removal of tissue, such as thrombus and the like, from a vessel in the body. Multiple catheters and an occluder-bearing guidewire tube at a thrombus site provide for expandable deployment of a compliant occluder against the vasculature walls distal to the thrombus. The expanded occluder is maneuvered proximally to urge thrombus into close proximity with a retractable capture cone located distally on a capture catheter where the thrombus is dislodged, entrained, and broken into pieces by the action of a fluid jet emanator and then evacuated through the capture catheter.
