Abstract: A catheter is usable to treat a hollow anatomical structure (HAS). The catheter comprises one or more shafts which extend away from a proximal end of the catheter toward a distal end thereof. The catheter further comprises an HAS constriction energy source located at or near the distal end of the catheter. The catheter further comprises at least one radially expandable transmural fluid delivery channel located in the catheter near the HAS constriction energy source.

Abstract: Apparatus and methods for treating a hollow anatomical structure comprises an implant sized for insertion into a hollow anatomical structure. The implant comprises a plurality of loose, bulked fibers. The fibers are formed from one or more bioabsorbable materials. Upon implantation, the apparatus causes a partial occlusion of the hollow anatomical structure, followed by a complete or substantially complete occlusion.

Abstract: The disclosure relates to the use of subcutaneous illumination during phlebectomy procedures, and to devices and methods for performing hook phlebectomy while visualizing veins and surrounding tissue using light emitted subcutaneously and beneath the surgical area. An apparatus comprises, in one embodiment, a handle, an illuminator portion extending distally from the handle, the illuminator portion comprising an elongate member configured for insertion into subcutaneous tissue, the illuminator portion comprising an elongate electroluminescent device extending along the illuminator portion, the electroluminescent device being configured to generate and emit light primarily in a generally radial direction, outward and away from a longitudinal axis of the illuminator portion.

Abstract: A method of treating a perforator vein comprises applying ultrasound to the perforator vein and occluding the perforator vein with the ultrasound. An apparatus for treating blood vessels comprises an ultrasound emitter, wherein the ultrasound emitter is configured to emit ultrasound at multiple therapeutic ultrasound frequencies during a treatment cycle. The apparatus further comprises an acoustic coupler in sonic communication with the emitter, wherein the acoustic coupler has an acoustic coupling surface configured to contact a patient and facilitate delivery of ultrasound to the patient and wherein the acoustic coupler provides a conduction path for ultrasound from the emitter to the acoustic coupling surface. The apparatus further comprises an acoustic coupler containing a displaceable acoustic coupling material.

Abstract: A method of treating a vein comprises accessing a vein at an access point spaced from a sapheno-femoral junction. A bioabsorbable fibrous body is implanted into the vein through the access point. The body is moved in the vein toward the sapheno-femoral junction.

Abstract: A method of treating a hollow anatomical structure of a patient comprises implanting a bioabsorbable fibrous body in a hollow anatomical structure. The body is secured in the hollow anatomical structure to limit migration of the body within the hollow anatomical structure.

Abstract: An apparatus for treating a hollow anatomical structure comprises an implant comprising a plurality of bioabsorbable fibers. The implant has a compressed state in which the implant can fit within a cylindrical tube having an inside diameter of 8 French or less. The implant is expandable from the compressed state to an expanded state in which the implant has sufficient size to span the inside diameter of a cylindrical tube having an inside diameter of 12 French or greater.

Abstract: An apparatus for treating a hollow anatomical structure comprises an implant sized for insertion into a hollow anatomical structure. The implant comprises a plurality of loose, bulked fibers. The fibers are formed from one or more bioabsorbable materials.

Abstract: An energy delivering probe is used for thermally coagulating and/or constricting hollow anatomical structures (HAS) including, but not limited to, blood vessels such as perforator veins. The probe includes a shaft and at least two electrodes where at least one of the electrodes has a perimeter that increases as it extends proximally.

Abstract: A treatment system for occluding a hollow anatomical structure comprises a treatment device sized for insertion into a hollow anatomical structure. The treatment device comprises a therapeutic element configured to treat the hollow anatomical structure. The system comprises a sensor configured to sense a first treatment parameter. A controller is in communication with the treatment device and with the sensor. The controller is configured to determine a second treatment parameter based on the first treatment parameter and output the second treatment parameter.

Abstract: This invention relates to occlusion of a hollow anatomical structure by inserting an occluding device or occluding material into a hollow anatomical structure or surrounding native tissue.
