A method of surgical dissection of tissue with a dissector comprising: an elongate shaft comprising a proximal portion and a distal portion, wherein the distal portion comprises a plurality of segments that articulate with respect to one another and the plurality of segments includes a distal segment having a distal end; and a handle attached to the proximal portion of the shaft, wherein the handle comprises controls for articulating the plurality of segments of the distal portion of the shaft with respect to one another, comprising the steps of: positioning the distal end of the dissector in a body; advancing the distal end through the body to dissect tissue; and simultaneously articulating the plurality of segments with respect to one another. A method of surgical dissection of tissue and guiding a second device to a desired physiological location with a first device.

Method of surgical dissection and/or guidance of other medical devices into body

A novel occluder application and clip device for treatment of embolic stroke caused by atrial fibrillation uses multiple sutures in a non directional handle to affix the occlusion device to the applicator and manipulate the occluder from an open and receiving position to a closed and occluding position. The occluder is retained in place by a clamping means related to locks retainers, resilient material or otherwise. An actuator mechanism is used to manipulate the occluder to a locked or occluding position. The applicator with the occluder attached has a low profile and remote manipulations to allow the occluder to be delivered to the clamping location within a patient through a small incision or delivery port such as a trocar cannula or the like.

Methods and devices for occlusion of an atrial appendage

An apparatus for oxygenating blood including a housing and an oxygenator bundle. The housing defines a primary chamber, a blood inlet port open to the primary chamber, and a blood outlet region. The outlet region includes a blood outlet port, an outlet chamber open to the outlet port, and a partition. The partition establishes spaced apart, first and second passageways from the primary chamber to the outlet chamber. The oxygenator bundle is disposed within the primary chamber. A blood flow path is formed from the blood inlet port, through the oxygenator bundle and to the blood outlet port, and includes first and second outlet flow paths within the outlet chamber via the first and second passageways, respectively. The first and second outlet blood flow paths merge at the blood outlet port. A dual port blood outlet is created, increasing mixing of blood immediately upstream of the outlet port.

Dual outlet oxygenator for treating blood in an extracorporeal blood circuit

The invention provides a system for occluding a left atrial appendage of a patient. The system can include a ring occluder that can be positioned around the left atrial appendage and a ring applicator to position the ring occluder with respect to the left atrial appendage. The system can also provide a tissue-grasping tool that is separable from the ring applicator tool.

Device for occlusion of a left atrial appendage

Disclosed is an apparatus for oxygenating and controlling the temperature of blood in an extracorporeal circuit. The apparatus has an inlet and an outlet that is located radially outward from the inlet in order to define a flowpath through the apparatus. The apparatus comprises: a core that is substantially centrally located in the apparatus and to which blood from a patient can be supplied through the inlet; a heat exchanger comprising a plurality of heat transfer elements that are arranged around the core and between which blood from the core can move radially outward; and an oxygenator comprising a plurality of gas exchange elements that are arranged around the heat exchanger and between which blood from the heat exchanger can move radially outward before exiting the apparatus through the outlet.

Radial design oxygenator with heat exchanger

Tissue stabilizers including a clamp assembly, a turret assembly, an articulating arm having a tension element extending therethrough, a collet assembly and a head-link assembly are disclosed. Methods of stabilizing tissue are also disclosed.
