Filed:

Sep 29, 2011

Appl. No.:

13/249203

Inventors:

Jessica LIANG - Irvine CA, US

Assignee:

TYCO HEALTHCARE GROUP LP - Mansfield MD

International Classification:

A61M 29/00

US Classification:

606195

Abstract:

A medical device detachment system receives an elongate delivery member, having a lumen, and an elongate core member. The system includes a housing, a user input mechanism for receiving a user input to effect detachment of a medical device, such as an embolic coil, from a distal end of the delivery member, and a grasping mechanism for grasping and moving a proximal end of the core member relative to a proximal end of the delivery member. The system also includes a first sensor detecting positioning of the proximal end of the core member within the housing, and a second sensor, detecting movement of the grasping mechanism. An indicator is connected to the first and second proximity sensors and provides feedback to a user.

International Classification:

A61B 17/12

Abstract:

Devices, systems, and methods for treating vascular defects are disclosed herein. One aspect of the present technology, for example, includes an occlusive device comprising a mesh having a low-profile state for intravascular delivery to the aneurysm and a deployed state, the mesh comprising a first end portion, a second end portion, and a length extending between the first and second end portions, and a first lateral edge, a second lateral edge, and a width extending between the first and second lateral edges. The mesh may have a predetermined shape in the deployed state in which (a) the mesh is curved along its width, (b) the mesh is curved along its length, and (c) the mesh has an undulating contour across at least a portion of one or both of its length or its width. The mesh is configured to be positioned within the aneurysm in the deployed state such that the mesh extends over the neck of the aneurysm.

International Classification:

A61B 17/22
A61F 2/95
A61B 17/221

Abstract:

Retrieval of material from vessel lumens can be improved by electrically enhancing attachment of the material to the removal device. The removal device can have a core assembly that includes a hypotube coupled to a first electrical terminal and a pushwire coupled to a second electrical terminal, the pushwire extending through the hypotube lumen. An insulating layer separates the hypotube and the pushwire, and an interventional element is coupled to a distal end of the pushwire. The interventional element can be disposed adjacent to a thrombus. An electrical signal is delivered to the interventional element to promote adhesion of the thrombus to the interventional element. The electrical signal can optionally be a periodic waveform, and the total energy delivered can be between 0.75-24,000 mJ and the peak current delivered via the electrical signal can be between 0.5-5 mA.
