A method of implanting and securing an implantable flow connector in a body of a patient for providing communication of a first space within the body of the patient with a second space within the body of the patient. The method includes providing a flow connector having a lumen having a first orifice and a second orifice, inserting a retention device into the first space within the body, subsequently inserting the flow connector through an opening in the retention device so the second portion of the flow connector extends into the first space within the body and placing the second space within the body over the retention device.

Implantable flow connector

The subject invention is directed to devices and methods for producing devices for regulating blood flow in the venous system. In particular, the invention provides for artificial valves designed to regulate the flow of blood in human vessels, wherein such artificial valves include superior properties including fatigue resistance, biocompatibility, and ease of manufacture.

Fatigue-resistant flow regulating device and manufacturing methods

An implantable device for regulating blood flow through a blood vessel comprising an elongated support dimensioned and configured to be implanted in a blood vessel. The support includes a linking member linking axially spaced apart portions to one another. A valve membrane extends between the axially spaced apart support portions and includes first region folded over the first linking member and attached thereto and a second region adjacent the first region and unattached to the first linking member. The second region is movable between a first position to enable blood flow and a second position to inhibit blood flow.

Device for regulating blood flow

A medical guidewire system including an inner member having an outer diameter and an outer member having an inner diameter, the inner diameter being larger than the outer diameter. The inner and outer members are relatively slidable to adjust a stiffness of the guidewire system. The lumen of the outer member forms a gap for fluid flow therethrough. A connector to the inner member and a fluid infusion channel communicating with the gap for injection of fluid through the gap to exit a distal portion of the outer member.

Guidewire with adjustable stiffness

A system for stapling tissue comprises a flexible endoscope and an operative head including a pair of opposed, curved tissue clamping jaws sized to pass through an esophagus, the jaws being moveable with respect to one another between an open tissue receiving configuration and a closed tissue clamping configuration, a first one of the curved jaws including a stapling mechanism and a second one of the jaws including a staple forming anvil surface, the stapling mechanism including staple slots through which staples are fired arranged in a row extending from a proximal end of the first jaw to a distal end thereof in combination with a control handle which, when the operative head is in an operative position within one of a patient's stomach and esophagus, remains outside the patient, the control handle including a first actuator for moving the jaws relative to one another and a second actuator for operating the stapling mechanism.

Apparatus and method for resectioning gastro-esophageal tissue

A thrombectomy apparatus for breaking up thrombus or other obstructive material in a lumen of a vascular graft or vessel. The apparatus includes a wire having a first configuration and a second deployed configuration, the wire having a straighter configuration in the first configuration. The wire is operatively connected to a motor for rotation of the wire to contact and break up the thrombus or other obstructive material. A blocking device at a distal portion of the apparatus is movable between a collapsed configuration and an expanded configuration, and is configured in the expanded configuration to block thrombus dislodged by rotation of the wire.

Rotational thrombectomy wire with blocking device

A surgical instrument for cutting and grasping tissue comprising a handle assembly, an elongated member and first and second jaws. A first movable member moves the second jaw in a first direction about a first pivot axis in a grasping action and a second movable member moves the second jaw in a second direction different than the first direction and about a second pivot axis in a cutting action. A switch is positioned at the proximal portion of the instrument and a selecting member is actuated by movement of the switch, the selecting member movable between a first position to enable movement of the second jaw in the first direction and prohibit movement in the second direction and a second position to enable movement of the second jaw in the second direction and prohibit movement in the first direction.

Surgical instrument for grasping and cutting tissue

A vascular device comprising a plurality of vessel engaging members and a valve. The device is movable from a collapsed insertion position having a first diameter to a second expanded position having a second diameter larger than the first diameter. The plurality of vessel engaging members extend outwardly from the device for securely engaging the internal wall of a vessel upon expansion of the device to the second expanded position, wherein the vessel engaging members pull the internal wall of the vessel radially inwardly upon movement of the device from the second expanded position toward a first expanded position having a third diameter greater than the first diameter and less than the second diameter. In the first expanded position the valve is movable between an open position to allow blood flow therethrough to a closed position to prevent blood flow.

Vascular device with valve for approximating vessel wall

A medical guidewire system including an inner member having an outer diameter and an outer member having an inner diameter, the inner diameter being larger than the outer diameter. The inner and outer members are relatively slidable to adjust a stiffness of the guidewire system. The lumen of the outer member forms a gap for fluid flow therethrough. A connector has a first end portion connected to the outer member, a second end portion connected to the inner member and a fluid infusion channel communicating with the gap for injection of fluid through the gap to exit a distal portion of the outer member.

A system for stapling tissue includes a stapling head and a control unit. The stapling head includes an endoscope receiving lumen extending therethrough and first and second jaws movable with respect to one another between a tissue receiving configuration and a tissue stapling configuration. The first jaw includes a staple firing mechanism and the second jaw includes a staple forming surface. The stapling head further includes gross and fine movement mechanisms controlling gross and fine movements, respectively, of one of the first and second jaws relative to the other of the first and second jaws. The control unit includes a first actuator controlling the gross and fine movement mechanisms and a second actuator operating the stapling mechanism.
