US Classification:

604191, 604224, 604227, 222137, 222288, 222390

Abstract:

Devices and methods for simultaneous injection or delivery of two or more substances from separate syringes. The syringes are loaded into a device that has a handle and a screw driven mechanism for simultaneously depressing the plungers of the syringes. The user grasps the handle and positions the device. Thereafter, the screw mechanism is used to simultaneously advance the plungers of the syringes thereby simultaneously expelling the substances from the syringes.

International Classification:

A61B 17/22

US Classification:

606159, 606128, 606170

Abstract:

An obstruction removal system for percutaneous removal of clots or obstructions within the vascular system is disclosed. The obstruction removal system includes a multi-lumen catheter with a plurality of circulating capture devices attached to or integral with a drive belt. The circulating capture or interference devices affect removal of the clot or obstruction bit-by-bit through a series of passes. The obstruction removal system may include one or more drive mechanisms, such as a pulley system and/or a vacuum source and/or a pressurization source, on its proximal end for driving the drive belt and capture devices through the catheter in a circulating manner. The obstruction removal system may also include one or more cleaning mechanisms, such as a vacuum chamber and/or a fluid rinse chamber, for removing the captured clot pieces from the capture devices.

International Classification:

A61M 25/00

US Classification:

600424, 606130, 604528

Abstract:

Magnetic resonance image (MRI) guided tissue penetrating catheters and their methods of use. One or more MRI apparatus (e. g. , one or more coils) are positioned on or in a catheter device that includes a tissue penetrator that may be used to form a penetration tract from a body lumen in which the catheter is positioned to a target location outside of that body lumen. The MRI apparatus (e. g. , coil(s)) is/are used in conjunction with an MRI imaging system to indicate the position and/or rotational orientation of the penetrating catheter within the subject's body.

International Classification:

A61F 2/24

US Classification:

623 211

Abstract:

Delivery devices and methods for percutaneously delivering a prosthetic valve to the heart of a patient. These prosthetic valves may be configured to provide complimentary features that promote optimal placement of the prosthetic valve in a native heart valve, such as the aortic valve, mitral valve, pulmonic valve, and/or tricuspid valve. The delivery device includes a release sheath assembly housed within an outer delivery sheath. A release sheath component of the assembly captures a portion of the prosthetic valve to the delivery device, and effectuates complete release of the prosthetic valve with retraction of the outer sheath.

Abstract:

Methods and catheter devices/systems for removing some or all of the lipid core material from vulnerable plaque and/or for introducing one or more therapeutic substance into vulnerable plaque. The vulnerable plaque may be entered by a penetrator that is advanced into the vulnerable plaque from a catheter device that incorporates an on-board imaging, sensing or vulnerable plaque locating apparatus.

Assignee:

Medtronic Vascular, Inc. - Santa Rosa CA

International Classification:

A61M 5/46

US Classification:

604117

Abstract:

Devices and methods for limiting the depth to which a penetrator is advanced into an organ or mass of tissue. The device generally comprises a first member and a second member. The penetrator is attached to and extends from a second member. The first member has a penetrator shroud and a hollow bore extending therethrough. The second member is engageable with the first member such that a distal portion of the penetrator extends through the penetrator shroud. The distance to which the penetrator protrudes out of and beyond the distal end of the penetrator shroud is adjustable in accordance with the desired depth of penetration. The penetrator may then be advanced into the organ or tissue mass until the distal end of the shroud abuts against the organ or tissue mass, thereby stopping further advancement of the penetrator. The penetrator may have one or more lumen(s) for aspirating or infusing substances.

International Classification:

A61F 2/06

US Classification:

623 111, 623 123

Abstract:

A delivery system for delivering a stented prosthetic heart valve to a lumen of a patient, the delivery system including a tubular body having a proximal end, a distal end, and a base portion with a plurality of extending elements, wherein each of the extending elements is engageable with a portion of a stent of a prosthetic heart valve. The delivery system further includes a sleeve having an inner area. The sheath is longitudinally moveable relative to the base portion from a first position where the inner area of the sleeve at least partially covers the extending elements of the base portion to a second position where the extending elements are not positioned within the inner area of the sleeve.
