Patent number: 10743862Abstract: A laparoscopic suturing device that allows the insertion and formation of intracorporeal knots in a safe and speedy manner during laparoscopic procedures. The laparoscopic suturing device includes an ergonomic handle and a long tubular shaft that contains a connecting rod inside. The proximal end of said connecting rod is attached to a deploying knob and its distal end is linked to a movable needle support that contains a suturing needle. The suturing device is inserted into the gas distended abdominal cavity with the needle in a straight position through a laparoscopic cannula and then by moving backwards said deploying knob the needle is deployed in a right angle allowing the insertion of a variety of sutures. The laparoscopic suturing device is provided with an encasement to keep a spool of suture material in place.Type: GrantFiled: February 15, 2018Date of Patent: August 18, 2020Inventor: Alfredo Alvarado

Patent number: 10100803Abstract: An ocean wave-crest powered electrical generator comprises a buoyant vessel anchored to the sea floor by mooring chains. The vessel defines a substantial opening at the bow leading to a paddle wheel such that ocean wave crests flow past the paddle wheel while passing through the generator thereby capturing the power of the continuous wave crests passing through the bow opening. The paddle wheel transforms energy from the breaking wave crests into kinetic energy that in turn activates an electric power generator. The wave crest electrical generator is permanently moored near the beach and allowed to rise and fall with the tide thus allowing for a continuous flow of ocean waves to be converted into power. Pumped storage provides a sustained flow of energy that is easy to regulate and this can be accomplished in combination with “energetic marinas” by constructing a reservoir on top of a near-by cliff, hill or tall building.Type: GrantFiled: September 7, 2016Date of Patent: October 16, 2018Inventor: Alfredo Alvarado

Patent number: 8795383Abstract: An improved composite prosthesis for laparoscopic repair of inguinal or femoral hernias, and also for the laparoscopic repair of large incisional ventral hernias incorporates two different layers, namely an upper layer made of polypropylene mesh to promote tissue ingrowth, and a lower layer formed with an adhesion barrier material to prevent adhesions to the intestines. Both layers are secured together with a highly visible dark seam at the perimeter of the prosthesis to assist the surgeon in visualizing the peripheral edge. The lower layer is slightly larger than the polypropylene mesh so there is an adhesion barrier edge around the prosthesis to conceal the edges of the polypropylene mesh. The upper layer includes a guiding cone to facilitate placement of the prosthesis at the exact center of the hernial defect.Type: GrantFiled: June 13, 2005Date of Patent: August 5, 2014Inventor: Alfredo Alvarado

Patent number: 8174409Abstract: An alphanumeric data input system for entering text into portable electronic devices by making linear traces or taps with a thumb or finger on a touch sensitive lineographic keypad. This keypad is conveniently located on the upper and left part of the electronic device in order to facilitate the natural motion of the thumb thus avoiding fatigue and strain of the same. The system allows the user to enter operational commands on the keypad, as well as entering of letters of different alphabets such as the Latin Alphabet, Mathematical Greek and Russian Alphabets and possibly of alphabets of other foreign languages including Japanese, Chinese and Korean. This system can be used for entering a combination of letters to speed up the writing process, and enables the entering of punctuation marks, typographical symbols and a wide range of mathematical symbols.Type: GrantFiled: September 13, 2007Date of Patent: May 8, 2012Inventor: Alfredo Alvarado

Patent number: 7942886Abstract: A transabdominal needle introducer for the repair of large ventral incisional hernias comprises a handle connected to a long tubular shaft and a disposable needle cartridge at its distal end. The handle has a round knob or head, and a needle pusher to extrude the needles out. The long tubular shaft contains two metal rods disposed inside thereof, one to change the angle of the cartridge, and the other one to extrude the needles. At the proximal end of the tubular shaft there is a rotatable cylindrical control provided with a spiral groove that moves a metal rod destined to pivot the needle cartridge. The second metal rod inside the shaft is assigned to extrude the needles and is connected to a flexible resilient wire that protrudes at the distal end of the tubular shaft and is provided at its distal end with an oval tip that engages a piston-type pusher inside the needle cartridge.Type: GrantFiled: June 25, 2008Date of Patent: May 17, 2011Inventor: Alfredo Alvarado
