Publication number: 20230346451Abstract: A system for performing a medical procedure in the intestine of a patient comprises a catheter for insertion into the intestine, a console, and a connector configured to operably attach the catheter to the console. The catheter comprises a shaft including a distal portion, and a functional assembly positioned on the distal portion of the shaft. The functional assembly is configured to receive fluid. The console comprises: a fluid reservoir configured to supply the fluid, a first syringe pump assembly configured to deliver the fluid to the functional assembly, a second syringe pump assembly configured to deliver the fluid to the functional assembly, a fluid heater configured to heat the fluid, and a waste fluid reservoir configured to receive the fluid. The system is configured to treat target tissue of the intestine of the patient. Methods of treating target tissue are also provided.Type: ApplicationFiled: December 6, 2022Publication date: November 2, 2023Applicant: Fractyl Health, Inc.Inventors: Philip Levin, Jay Caplan, Charles Abele, Greg Dierksen, Andrew Hollett, Thomas Kochem, Adam Jaynes, Jeff Johnson, Jeff Lesica, Lionel Stewart Maclean, Sara Morneau, Bruno Piazzarolo, Len Rosberg, Jonathan Seidmann, R.

Publication number: 20210299465Abstract: A system can deliver a specific amount of energy to a target region of a patients body by scanning an energy beam over a precise path. The system can include a beam-path determination unit that defines the path and a duration for an energy beam to deliver a dose and/or a fluence of energy to the target region of the patients body of the shape and/or the size. The system can also include an energy delivery system comprising an energy source that projects the energy beam for the duration and director device that directs (or scans) the energy beam along the path to deliver the dose and/or the fluence to the target region to achieve the dose profile and/or the fluence profile.Type: ApplicationFiled: August 9, 2019Publication date: September 30, 2021Inventor: Philip Levin

Publication number: 20080161748Abstract: The present invention relates to devices and methods for killing and/or debilitating pathogenic microorganisms, such as the H. pylori bacteria within a patient's body. A light source is provided that emits electromagnetic radiation having wavelengths within the visible spectrum. The light source can be internal and/or external to the patient's body. For embodiments having a light source external to the body, a light guide is provided for transferring electromagnetic radiation from the light source to a location within the patient's body. The light guide has a proximal end optically coupled to the light source and a distal end dimensioned for insertion into a patient's body. A delivery element is also provided to optically couple electromagnetic radiation from the light to a location with a patient's body.Type: ApplicationFiled: August 13, 2007Publication date: July 3, 2008Inventors: Marc Joshua Tolkoff, Robert Arcangeli, Philip Levin

Patent number: 5394394Abstract: The classifier device disclosed herein analyzes message headers of the type which comprise a sequence of bit groups presented successively. The device employs a read/write memory for storing at a multiplicity of addresses, an alterable parse graph of instructions. The parse graph instructions include node instructions which comprise opcodes in association with respective next address characterizing data and terminator instructions which comprise identifying data for previously characterized header types. A logical processor responds to a node instruction read from memory either by initiating another memory read at a next address which, given the current state of the processor, is determinable from the current node instruction and the current header bit group or by outputting data indicating recognition failure if no next address is determinable. The logical processor responds to a terminator instruction by outputting respective header identifying data.Type: GrantFiled: June 24, 1993Date of Patent: February 28, 1995Assignee: Bolt Beranek and Newman Inc.Inventors: William R.
