Patent number: 9615875Abstract: A surgical instrument for thermally-mediated therapies in targeted tissue volumes and for causing thermal effects in polymer tissue-contacting members. In one embodiment, the instrument has a working end with an interior chamber that is supplied with a biocompatible liquid. An energy source causes a liquid-to-vapor phase change within the interior of the instrument. The vapor phase media then is ejected from the working surface of the instrument, and a controlled vapor-to-liquid phase change in an interface with tissue applies thermal energy substantially equal to the heat of vaporization to ablate tissue. The vapor-to-liquid phase transitions, or internal energy releases, can be provided about thin-film flexible structures for engaging body lumens and cavities. An exemplary embodiment can be used for shrinking, sealing, welding or creating lesions in tissue—while causing limited collateral thermal damage and while totally eliminating electrical current flow in the engaged tissue.Type: GrantFiled: March 17, 2014Date of Patent: April 11, 2017Assignee: Tsunami Med Tech, LLCInventor: John H.

Insulin, improves memory; also augments and amplifies the effects of the adjuvant therapeutic agents (paracrine and intracrine effects) and consequently reduces the ? amyloid, its soluble precursors, prevents damage to the neuronal skeletal network (taupathy), and blocks glutamate excitotoxicity, reduces brain inflammation, prevents apoptosis, and increases the acetylcholine levels in the neurons and synapses; by using a combination of insulin, bexarotene, ketamine, Etanercept, IGF-1, and physostigmine therapeutic agents.Type: ApplicationFiled: September 19, 2014Publication date: March 12, 2015Inventor: Totada R.

Publication number: 20150065944Abstract: A drug-delivery device includes a body configured for attachment to a handle of an ablation device, a shaft portion defining a passageway therein, and a delivery lumen to provide for drug delivery to tissue. The body includes a proximal portion, a distal portion, and a contoured portion disposed therebetween. The contoured portion is configured for engagement with a contoured portion of the handle of the ablation device. The shaft portion includes a proximal end and a distal end. The proximal end of the shaft engages with an opening defined in the distal end of the body. The passageway of the shaft portion is configured to receive the delivery lumen slideably moveably therein. The delivery lumen includes a proximal portion and a distal portion. The drug-delivery device also includes a knob member coupled to the proximal portion of the delivery lumen.Type: ApplicationFiled: August 27, 2013Publication date: March 5, 2015Applicant: COVIDIEN LPInventors: RACHIT OHRI, LAN PHAM, PHILLIP D.
