Devices and methods for their use in percutaneously increasing the aortic valve flow of a stenotic aortic valve are provided. The subject devices include an aortic valve isolation element, a shunt element and an aortic valve flushing element. Also provided are systems and kits that include the subject devices and can be employed in practicing the subject methods. The subject devices, methods, systems and kits find use in treating conditions associated with the presence of stenotic aortic valves.

The present invention provides various pharmaceutically active topical delivery compositions. In particular, compositions of the present invention are present in a pressurized container comprising a quick-breaking alcoholic foaming agent, such that when the composition is released, i.e., dispensed, from the pressurized container, a quick-breaking temperature sensitive foam is formed. In addition, the present invention provides various aspects related to such compositions, including methods for modulating a foam characteristic, methods for improving the shelf-life of a pharmaceutically active compound, methods for the percutaneous treatment of various diseases, infections, and illnesses, and methods for evaluating foam characteristics.

A medical device and method for percutaneously treating a heart valve. In one embodiment, the medical device includes a catheter having a proximal portion, a distal portion, and a notch formed near the distal portion. A cutting element may be disposed within the distal portion and is moveable across the notch to slice through a heart chord.

Methods and compositions for the topical or transdermal treatment of neuropathy. More particularly, transdermal or topical compositions including a combination of ingredients that provide a surprising degree of effective relief from the symptoms of peripheral neuropathy and methods for administering the compositions to treat various neuropathies.

The methods and devices disclosed herein pertain to the percutaneous treatment of various forms of aortic dissection by at least partially filling the false lumen of the aortic dissection with a stabilization agent percutaneously and steps to decrease the size of the false lumen using the devices. Fluid maybe aspirated from the false lumen to decrease the volume of the false lumen. And the entrance opening between the true lumen and the false lumen may be sealed with a sealing agent such as a biocompatible adhesive. The medical devices disclosed herein generally comprise an extendable sealing element that is used in conjunction with a catheter to expand the true lumen while reducing the size of the false lumen. The device has the ability to aspirate and / or deliver fluid containing the stabilization agent into the false lumen.

The present invention provides devices and methods for percutaneously retrieving an embolized or malpositioned heart valve or foreign bodies from a patient's body. Several of these devices may include a catheter system with expandable and retractable baskets attached to a catheter and guidewire system. The guidewire may be inserted through the lumen of the embolized or malpositioned heart valve, capturing the valve in the baskets, and deploying a mechanism to crush the valve within the baskets. Then the crushed baskets and valve may be retrieved either from the body or to a safer location such as but not limited to the descending aorta. This system is advantageous because it does not require open surgery to retrieve the valve or embolized material.

The invention discloses a novel headache therapeutic apparatus, which comprises a wearing frame arranged in cooperation with a human head, a massage and percutaneous drug permeation device, a drug liquid delivery pipe, a drug liquid delivery device and a drug liquid storage box. The massage frame is provided with at least one acupoint positioning hole opposite to the human head, and the massage and percutaneous drug permeation device are installed on the massage frame and arranged opposite to the acupoint positioning hole. The drug liquid delivery device transfers the drugs in the drug liquidstorage box to the massage and percutaneous drug permeation device through the drug liquid delivery pipe, and the massage and percutaneous drug permeation device can simultaneously permeate and massage the corresponding acupoints. The novel headache therapeutic apparatus provided by the invention is different from the traditional medicine taking and injection, and adopts the mode of percutaneous treatment to infiltrate the medicine into the human body acupoints through the skin, thereby avoiding the drawbacks of oral administration and injection of the medicine, massaging the medicine while infiltrating the medicine, and can effectively alleviate the migraine problem of the patient.

The present invention comprises an implantable subcutaneous port for anchoring a transcutaneous treatment component. The implantable subcutaneous port comprises a body portion and one or more frangible lines formed within the body portion. The body portion is adapted for receiving the transcutaneous treatment component beneath the point of entry into the physiology of a patient and routing the transcutaneous treatment component. The body portion is produced from a deformable material and has an area footprint and defines a support wall through which the transcutaneous treatment component enters the body portion. Fracturing the one or more frangible lines formed within the body portion enables removal of the body portion from the physiology of a patient through a transcutaneous opening defining an area of less than thirty percent of the area footprint of the body portion.

The present invention comprises a deformable, implantable subcutaneous port for anchoring a transcutaneous treatment component. A port body portion having a normal area port footprint is adapted by means of a port orifice for receiving and anchoring the transcutaneous treatment component beneath the point of entry into the physiology of a patient and for routing the transcutaneous treatment component. The port body portion is produced from a deformable material and has structure and / or composition that provides deformability characteristics of the port such that collapsing, folding, stretching, elongating and / or twisting the port body portion into a modified port shape having a reduced-size port profile enables removal of the port body portion from the physiology of a patient through a relatively small transcutaneous opening.

Some embodiments are directed to methods and systems for percutaneously treating dissections in a patient's vasculature, such as, without limitation, the aorta. The method can include deploying a catheter containing a collapsed anchoring element, frame, and cover through a first vessel to an entry point of the dissection. The anchoring element can be secured to the second branch vessel. The frame can be expanded in the first branch vessel. The cover can be unfolded over at least a portion of the entry point. The cover then reduces blood flow into the entry point.
