Patent number: 11883029Abstract: The volume of a hyperinflated lung compartment is reduced by sealing a distal end of the catheter in an airway feeding the lung compartment. Air passes out of the lung compartment through a passage in the catheter while the patient exhales. A one-way flow element associated with the catheter prevents air from re-entering the lung compartment as the patient inhales. Over time, the pressure of regions surrounding the lung compartment cause it to collapse as the volume of air diminishes. Residual volume reduction effectively results in functional lung volume expansion. Optionally, the lung compartment may be sealed in order to permanently prevent air from re-entering the lung compartment.Type: GrantFiled: July 19, 2022Date of Patent: January 30, 2024Assignee: Pulmonx CorporationInventors: Nikolai Aljuri, Rodney C. Perkins, Niyazi Beyhan

Patent number: 11805374Abstract: Hearing systems for both hearing impaired and normal hearing subjects comprise an input transducer and a separate output transducer. The input transducer will include a light source for generating a light signal in response to either ambient sound or an external electronic sound signal. The output transducer will comprise a light-responsive transducer component which is adapted to receive light from the input transducer. The output transducer component will vibrate in response to the light input and produce vibrations in a component of a subject's hearing transduction pathway, such as the tympanic membrane, a bone in the ossicular chain, or directly on the cochlea, in order to produce neural signals representative of the original sound.Type: GrantFiled: September 15, 2021Date of Patent: October 31, 2023Assignee: Earlens CorporationInventors: Rodney C. Perkins, Vincent Pluvinage

Publication number: 20230063051Abstract: Prostate treatment using fluid stream to resect prostate tissue, thereby relieving symptoms of conditions such as BPH, prostatitis, and prostatic carcinoma. A device having a fluid delivery element is positioned within a lumen of the urethra within the prostate. A fluid stream is directed outwardly from the fluid delivery element toward a wall of the urethral lumen. The fluid delivery element is moved to scan the fluid stream over the wall to remove a volume of tissue surrounding the lumen. The fluid may be combined with therapeutically active substances or with substances that increase resection efficiency. Fluid force may be adjusted to provide selective tissue resection such that soft tissue is removed while harder tissue is left undamaged. In order to gain a working space within the urethra, another fluid may be introduced to insufflate the urethra in the region of treatment.Type: ApplicationFiled: October 20, 2022Publication date: March 2, 2023Applicant: AquaBeam, LLCInventors: Nikolai ALJURI, Rodney C.

Patent number: 11483665Abstract: Systems, devices, and methods for communication include an ear canal microphone configured for placement in the ear canal to detect high frequency sound localization cues. An external microphone positioned away from the ear canal can detect low frequency sound, such that feedback can be substantially reduced. The canal microphone and the external microphone are coupled to a transducer, such that the user perceives sound from the external microphone and the canal microphone with high frequency localization cues and decreased feedback. Wireless circuitry can be configured to connect to many devices with a wireless protocol, such that the user can receive and transmit audio signals. A bone conduction sensor can detect near-end speech of the user for transmission with the wireless circuitry in a noisy environment. Noise cancellation of background sounds near the user can be provided.Type: GrantFiled: October 22, 2020Date of Patent: October 25, 2022Assignee: Earlens CorporationInventors: Rodney C.

Patent number: 11323829Abstract: A support can be configured for placement in the middle ear to couple a transducer to the round window, such that the transducer can be removed from the round window without damaging the round window. The support can be configured to couple the transducer to the sound window such that the support can be removed from the round window. The support may be configured to decouple the transducer from the round window such that the transducer can be removed from the middle ear of the user, for example when the support is affixed to the middle ear. Removal of the transducer from the middle ear without damaging the round window can allow safe removal of the transducer, for example when the patient wishes to receive MRI imaging.Type: GrantFiled: December 20, 2019Date of Patent: May 3, 2022Assignee: Earlens CorporationInventors: Rodney C.

Publication number: 20210308484Abstract: A catheter treatment apparatus comprises an elongate tubular member and an expandable support. The expandable support comprises a radioactive substance to treat cancerous tissue and is configured to expand from a narrow profile for insertion to a wide profile to engage and treat tissue remaining after resection. The expandable support can be sized to fit within a volume of removed tissue to place the radioactive substance in proximity to the capsule and remaining tissue, to spare the capsule and proximate nerves and vessels to treat tissue in proximity to the capsule. The elongate tubular member may comprise a channel such as a lumen to pass a bodily fluid such as urine when the expandable support engages the tissue to treat the patient for a plurality of days. The treatment apparatus can be used to resect and diagnose tissue concurrently. Based on the diagnosis, targeted segmental treatment may be given.Type: ApplicationFiled: June 22, 2021Publication date: October 7, 2021Applicant: PROCEPT BioRobotics CorporationInventors: Nikolai ALJURI, Surag MANTRI, Rodney C.
