Energy based devices and methods for treatment of patent foramen ovale

Номер: US20120010608A1
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.

Systems for bone fracture repair are disclosed. One system includes a biocompatible putty that may be packed about a bone fracture to provide full loadbearing capabilities within days. The disclosed putties create an osteoconductive scaffold for bone regeneration and degrade over time to harmless 5 resorbable byproducts. Fixation devices for contacting an endosteal wall of an intramedullary (IM) canal of a fractured bone are also disclosed. One such fixation device includes a woven elongated structure fabricated from resorbable polymer filaments. The woven elongated structure has resilient properties that allow the woven 10 structure to be radially compressed and delivered to the IM canal using an insertion tube. When the insertion tube is removed, the woven structure expands towards its relaxed cross-sectional width to engage the endosteal wall. The woven elongated structure is impregnated with a resorbable polymer resin that cures in situ, or in the IM canal.

Clip Apparatus for Closing Septal Defects and Methods of Use

Номер: US20120296346A1
Автор: Richard S. Ginn

A device for closing a septal defect, such as a patent foramen ovale, includes a clip formed from a superelastic material that is inserted into a septum wall of a heart. The clip is advanced through a patient's vasculature, e.g., within a delivery apparatus, until the clip is disposed within a first chamber adjacent the septal defect. Tines of the clip are directed through a flap of tissue of the septal defect until the tines of the clip are disposed within a second opposing chamber. The clip then transforms into its relaxed state, wherein the tines of the clip engage with a surface of the second chamber, thereby substantially closing the septal opening.

Blockstent device and methods of use

Номер: US20140018838A1
Принадлежит: Novita Therapeutics LLC

What is disclosed is a medical device comprising a compressed, cylindrical or oblong, thin-walled, expandable metal structure (a “blockstent”) and a flexible, elongated device (a “delivery catheter”) to position the compressed blockstent into the lumen of a blood vessel segment to be treated, and methods of use for occlusion of treated blood vessel segments. A blockstent can be made with ductile metals such as gold, platinum, or silver such that the blockstent will conform to the shape of the lumen of the treated blood vessel segment during expansion and allow for the shape of the blockstent to be permanently changed by the application of an external force. The surface of the blockstent can be configured to promote local thrombus on the external surface of the blockstent and to promote the growth of tissue into the wall of the blockstent in order to occlude the treated blood vessel and fix the blockstent in place. The wall of the blockstent can also be configured to release drugs or pharmacologically active molecules such as those that promote thrombosis, cell proliferation, extracellular matrix deposition to promote this thrombus formation and tissue growth.
