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

Device and method for sub-xiphoid ablation of patient tissue. A sub-xiphoid access clamp has a handle, an elongate neck coupled to the handle and first and second opposing jaws. The first and second opposing jaws have first and second opposing relief segments being generally co-planar and concave with respect to one another to form a void therebetween, and first and second opposing elongate ablation elements positioned along the first and second opposing jaws and distal of the first and second opposing relief segments relative to the handle. The first and second opposing jaws are articulate between a closed position and an open position to admit, at least in part, a second portion of tissue of the patient within the void created by the first and second opposing relief segments while the first portion of tissue is positioned between the first and second ablation elements in the closed position.

Sub-xiphoid ablation clamp and method of sub-xiphoid ablation

A device and method for ablating tissue is disclosed comprising the steps of acquiring an anatomical image of a patient, correlating the image to the patient, guiding an ablating member within the patient while tracking the position of the ablating member in the patient, positioning the ablating member in a desired position to ablate tissue, emitting ablating energy from the ablating member to form an ablated tissue area and removing the ablating member from the patient.

Methods of using high intensity focused ultrasound to form an ablated tissue area containing a plurality of lesions

A method for treating a human patient includes emitting ultrasound energy from an ultrasound transducer positioned remotely from target tissue of the patient. The ultrasound transducer is positioned at a desired location relative to the patient and target tissue using location and imaging techniques. The method further includes focusing the ultrasound energy such that one or more focal points are directed to the target tissue of the patient and ablating the target tissue at each focal point. The target tissue is ablated via the focused ultrasound energy without ablating non-target tissue through which the ultrasound energy passes between the ultrasound transducer and the one or more focal points.

Method for ablating target tissue of a patient

A method for determining whether a medical device is appropriate for implanting into a cardiovascular conduit of a patient is disclosed comprising imaging a first section of the conduit of the patient into which the medical device is to be implanted during a first expanded state occurring at a first portion of a heart rhythm; reimaging the first section of the conduit of the patient during a first contracted state occurring at a second portion of the heart rhythm; deriving, from the imaging and the reimaging, dimensional characteristics of the first section of the conduit; and determining whether the medical device is appropriate for implantation in the first section of conduit based on the derived dimensional characteristics. The first section of the conduit includes a sizing device providing a selected radial force on the patient.

Image-guided heart valve placement

An ablation apparatus including a maneuvering mechanism, a conductive element attached to the apparatus, a sensor attached to the apparatus and an output device in communication with the sensor is provided. The sensor senses vibration during the ablation procedure and sends a signal to the output device to reduce power to the conductive element.

Vibration sensitive ablation device and method

An ablation catheter assembly including an elongate catheter body having a proximal portion, a distal portion and a lumen therethrough. A helical structure associated with the catheter distal portion carries a plurality of independently operable electrodes and is transformable between a low-profile configuration wherein a straightening element is positioned in the lumen and an expanded configuration wherein the straightening element is at least partially retracted from the spiral structure. When the helical structure is in the expanded configuration, a laterally offset tip portion extends distally therefrom.

Ablation catheters and associated systems and methods

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 ablation catheter assembly includes an elongate catheter body having a proximal portion, a distal portion and a lumen therethrough. A helical structure associated with the catheter distal portion carries a plurality of independently operable electrodes and is transformable between a low-profile configuration wherein a straightening element is positioned in the lumen and an expanded configuration wherein the straightening element is at least partially retracted from the spiral structure. When the helical structure is in the expanded configuration, a laterally offset tip portion extends distally therefrom.

Device, system and method for ablating tissue of a heart of a patient. The tissue is clamped between a pair of opposing jaws. A portion of the tissue is ablated at a first generally linear position on the tissue by applying ablative energy to two of a plurality of elongate electrodes, each of the two of the plurality of elongate electrodes being coupled in opposing relationship to each other and the pair of opposing jaws, respectively. An effectiveness of the ablation is sensed at a second generally linear position on the tissue with at least one of the plurality of elongate electrodes positioned on one of the pair of opposing jaws. The second linear position on the tissue is laterally distal to the first linear position on the tissue with respect to the atrium of the heart.
