  • Publication number: 20240108820
    Abstract: An atomization device and a method of predicting atomization time for the same are provided. The atomization device includes a control module, an atomization module and a breathing sensing module. The method includes: configuring the breath sensing module to detect inhalations of a user using the atomization device, so as to generate initial breath data correspondingly; and configuring the control module to perform: comparing inhalation data of the initial breath data with a valid inhalation standard to obtain valid inhalation data and filter noise; statistically analyzing the valid inhalation data to generate a predicted value of inhalation time; calculating an atomization time according to the predicted value of the inhalation time; and generating a driving signal to drive the atomization module to perform atomization according to the atomization time.

  • Publication number: 20230092775
    Abstract: Devices and methods are disclosed for managing and/or treating body tissues obstructing a hollow body lumen, including the prostatic lobe tissues obstructing the urethra, for example conditions including benign prostatic hyperplasia (BPH), bladder outlet obstruction (BOO), benign prostatic obstruction (BPO) and associated lower urinary tract symptoms (LUTS). A prostatic implant deployment and delivery system may have a controlled release mechanism, a handle mechanism and an irrigation system. The controlled release mechanism includes a disengageable connection between a pusher member and the prostatic implant with a control member. The handle mechanism includes a plunger for advancing the pusher member and an actuator for withdrawing the control member. The irrigation system may define two fluid paths.

  • Publication number: 20230089310
    Abstract: Devices and methods are disclosed for determining prostatic urethral length. A balloon catheter subassembly is in fluid communication between an inner cavity of a syringe body and an expandable balloon is positioned at a distal end of the balloon catheter subassembly. An adapter secured to the syringe body having a syringe plunger includes a lock that engages the syringe plunger at a predefined position with respect to the syringe body corresponding to a desired inflation state of the expandable balloon. Prostatic urethral length can then be determined using markings indicating distance from the expandable balloon.

  • Publication number: 20220387165
    Abstract: Devices and methods are disclosed for determining prostatic urethral length. A measuring device having an elongated shaft member with associated markings may be advanced through a working channel of the cystoscope so that a positioning aid disposed on the elongated shaft member is located at a bladder neck of the patient. A first position of the elongated shaft member is determined using the markings. The elongated shaft member is then withdrawn to a second position at which the positioning aid is located at the patient's verumontanum. The prostatic urethral length is determined based at least in part on relative translational movement of the elongated shaft member between the first position and the second position using the markings.

  • Patent number: 11219447
    Abstract: Excess suture material may be trimmed after knot tying using a device having an elongated shaft, an elongated tubular cutter disposed over the shaft and an elongated tubular barrel disposed over the cutter. A suture loader at a distal end of the shaft that engages suture material may be opened and closed by a first actuator that causes relative motion between the shaft and the barrel. A second actuator may cause relative motion between the cutter and both of the barrel and the shaft to sever suture material engaged by the closed suture loader.

  • Patent number: 11076849
    Abstract: An elongated deployment shaft carrying a needle deployment assembly with needles carrying sutures and a stabilizer. A catcher tube over the shaft having a catcher assembly at a distal end may retain a portion of the needles when passed through the tissue into engagement with catcher assembly. The catcher and needle deployment assemblies are configured to asynchronously engage the plurality of needles when moved distally beyond the catcher assembly. A sheath over the catcher tube may sandwich the tissue against the stabilizer when expanded. A first actuator may move catcher tube distally to decrease distance between proximal and distal ends of the stabilizer expand it and may move the sheath distally to sandwich the tissue. A second actuator may deflect the needles outward to move proximally through the tissue and engage the catcher and return a portion of each not retained by the catcher to a distal position.

  • Patent number: 10959720
    Abstract: A knot may be formed in suture material using a device having an elongated body with a longitudinal axis and a holder. A rail portion of the suture material is secured with a first grasper on the elongated body and a non-rail portion of the suture material is secured with a second grasper on the holder. A plurality of helical windings may be created with the non-rail portion. Detaching the holder from the elongated body in a motion away from the longitudinal axis of the elongated body completes the knot. The holder may be wrapped around the elongated body in a knot-forming pattern.
