Energy based devices and methods for treatment of patent foramen ovale

Номер: US20120010608A1
Автор: Dan Francis, Hanson S. Gifford, Iii, Jose Alejandro, Kenneth Horne, Mark E. Deem, William Malecki
Принадлежит: Terumo Corp

Methods and apparatus for treatment of patent foramen ovale (PFO) provide for applying energy to tissues adjacent the PFO with a catheter device to substantially close the PFO acutely. Apparatus generally includes a catheter device having at least one energy transmission member at or near its distal end configured to apply energy to PFO tissues to acutely, substantially close the PFO. Applied energy may be monopolar or bipolar radiofrequency energy or any other suitable energy, such as laser, microwave, ultrasound, resistive heating or the like. Some embodiments of a catheter device fuirther include one or more tissue apposition members near the distal end for helping bring PFO tissues together, such as a PFO covering member, a vacuum applying member and/or the like. PFO closure via energy-based approaches of the invention may help prevent stroke, treat migraine headache, and possibly treat or prevent other medical conditions.

Endoscopic balloon tissue dissector and retractor

Номер: US20120016196A1
Автор: Parviz Kambin, Sheila P. Kambin
Принадлежит: Individual

In endoscopic surgery, a retractor having independently spreadable retractor blades mounted at the distal end of a tube is introduced percutaneously. A balloon dissector is passed through the tube and expanded. Following dissection by expansion of the balloon, the balloon is contracted, the tube is advanced, and the dissected tissue is spread by moving the blades apart from each other. The balloon dissector is withdrawn and another instrument is then introduced to carry out surgery on the anatomical structure exposed by the dissection and spreading steps.

Minimally invasive suction retractor

Номер: US20120078059A1
Автор: John R. Pepper, Miguelangelo J. Perez-Cruet
Принадлежит: MI4Spine LLC

A suction retractor including an elongated tube that is operable to be inserted through a tubular retractor used in minimally invasive surgical procedures. One end of the tube is coupled to a handle having a chamber and the other end of the tube is coupled to a curved retractor portion, where the retractor portion allows the surgeon to hold back various anatomies during the surgical procedure. Thus, the suction retractor provides two functions that may otherwise require two different instruments. The retractor portion includes a series of parallel groves that allow liquids, such as blood, to flow along the retractor portion and into a suction port at the end of the tube. A suction device can be coupled to an outlet port in the handle that causes the blood and other surgical material to be sucked through the tube and out of the handle.

An air gap retractor illumination system includes any suitable retractor with a channel in the blade to accommodate an air gap illuminator. The illuminator is preferably made from a suitable light conducting plastic material. The illuminator has active portions in which light passes and inactive or dead zones in which light does not pass. The illuminator is formed to have an air gap surrounding any active portion of the illuminator extending from the light input to the light output portion. The dead zones may include elements to allow the illuminator to securely engage the retractor. The light output portion of the illuminator contains from two to eight output zones, each zone having specially designed output optical structures that control and direct light to escape the illuminator to shine onto a predetermined area of interest or to form one or more predetermined shapes or footprints.

A retractor ( 101 ) for retracting the margins of a wound opening ( 103 ) comprises an inner anchoring O-ring ( 105 ) attached to a cylindrical sleeve ( 106 ) at a distal end and a reinforcing O-ring ( 109 ) attached to a proximal end of the sleeve ( 106 ). The sleeve ( 106 ) is led between an inner ring part ( 110 ) and a corresponding recess ( 116 ) in an outer ring part ( 111 ). The outer ring part ( 111 ) has anchor formations ( 120 ) over which the proximal end of the sleeve ( 106 ) is attached to anchor the sleeve ( 106 ). To retract the wound opening ( 103 ) the sleeve ( 106 ) is pulled while the guide rings ( 110, 111 ) are moved against the tissue surrounding the wound opening ( 103 ). This pulls the inner O-ring ( 105 ) against the inside of the tissue adjacent the wound opening ( 103 ), and retracts the wound opening ( 103 ). The sleeve ( 106 ) is manipulated locally for maximum retraction efficiency.

An improved surgical dilator extractor is introduced into the abdominal cavity through a trocar cannula and expanded, forming a tissue receiving space, at the distal end. The tissue receiving space is enlarged by passing a grasper through a lumen of the dilator extractor to interact with a guide surface on the interior of dilator extractor to expand a dilator portion having a single leaf beyond the natural resiliency of the leaf. The tissue being extracted is then manipulated into the space with the grasper. The tissue is then removed from the cavity by the surgeon applying a force onto the dilator extractor that insures the elongation of the tissue and temporarily dilates the entry wound to the extent necessary for the tissue to be removed. Alternative embodiments of the surgical dilator extractor and related instrument tool sets and methods for the use thereof also are disclosed.

Provided herein is a method for treating spinal stenosis comprising percutaneously accessing the epidural space from a first side of the spine. The first side of the spine is located on one side of the medial plane with respect to the spinal cord. A tissue removal tool is then advanced through the first side of the epidural space into the other side of the epidural space, where the other side of the epidural space is located on the other side of the medial plane of the spinal cord. Once the tissue removal tool is located on the second side of the medial plane, stenosis can be reduced using the tissue removal tool.
