  • Patent number: 11904104
    Abstract: An intravascular heart pump assembly can include a rotor with at least one impeller blade, and a cannula. The present application describes various cannulas that can be manufactured from multiple layers of material to improve flexibility, manufacturability, and durability without increasing an outer diameter of the cannula. In one embodiment, the cannula includes an inflow section having a sheet formed of a shape memory material embedded within a polymer and having at least one lateral hole or aperture in the inflow section. The at least one lateral hole is defined by a first hole in the sheet and a second hole in the outer polymer layer of the cannula.

  • Patent number: 11904105
    Abstract: A cannula-catheter bonding method and apparatus can include a needle having a specifically configured connector end to reduce the risk of the connector end disengaging with an adapter (e.g., a catheter, a cannula, or a connector of a Huber needle assembly, etc.). The specifically configured needle connector end can be a formation, such as a barb, a bead, an annular structure, a rib, etc. The formation can be formed on the connector end, and may be elongated with a conical shaped nose leading to a base with a bottom. The formation can be used to prevent movement of the needle relative to the adapter. A method for producing the formation can include forming a mold for the formation in a plate, where the connector end can then be placed within the mold so that curable material can be disposed within the mold. Upon hardening of the curable material, the formation can take the shape of at least a portion of the mold.

  • Patent number: 11904106
    Abstract: The invention provides an improved indwelling urinary catheter of the inflatable type having a unique, low profile device by which to retain the catheter within the bladder, so that urine can be removed therefrom while avoiding obstruction to the descending fetal vertex during the process of labor and delivery. Thus, making it better suited for obstetrical applications. The retaining device consumes less obstructing volume in the bladder than that which would ordinarily be consumed by a conventional Foley-style balloon, whereby both the frequency and severity of fetal vertex obstruction and its resulting increased time of labor, operative delivery and injury to maternal urologic tissue can be reduced. The obstetrical foley retains the tradition Foley-style balloon distal to the improved low-profile laboring balloon for insufflation in the event a surgical delivery by cesarean section is indicated.

  • Patent number: 11904111
    Abstract: Disclosed herein are catheter assemblies (100) with a locator tip (134) proximal to the distal tip (112) of a catheter tube (110). The locator tip is sized to remain outside a female urethra and configured to allow the catheter tube to pass there through. As an example, the locator tip allows a woman using a urinary catheter to target her urethra without exposing the catheter tube to tissue until the urethra is located and insertion is initiated. This avoids infecting the urethra with a catheter tube that has been contaminated by bacteria around the urethra.

  • Patent number: 11904114
    Abstract: An integrated vascular access device can include strain relief features to minimize the likelihood of the extension tubing becoming kinked during use. These strain relief features can be configured at both ends of the extension tubing to minimize the likelihood of kinking at the interfaces to the catheter adapter and luer adapter. To provide strain relief at the catheter adapter end of the extension tubing, an interface formed of a flexible material can be aligned with an extension of the catheter adapter into which the extension tubing inserts. The interface can be integrated into a stabilization platform or formed separately from a stabilization platform. To provide strain relief at the luer adapter end of the extension tubing, a flexible spacer can be coupled to a distal end of the adapter and have a distal portion that is positioned around the extension tube.

The walls are thicker at the other end than at the one end. The method includes filling the volume with polymer and releasing a molded part from said mold and cooling a molded part resulting from the filling and releasing such that temperature that the widths of the pair of slots is non-uniform after cooling. The needle guard has upper and lower jaws defining a channel and coming together at a hinge. A winged needle can be inserted between the jaws, with the wings of the winged needle passing through slots between the jaws.

  • Patent number: 11904138
    Abstract: Disclosed herein are techniques related to glucose level management without carbohydrate counting. The techniques may involve obtaining contextual information for a meal, predicting amounts of glucose to be absorbed into a bloodstream of the patient over a duration of time due to consumption of the meal based on the contextual information for the meal, determining one or more amounts of insulin to counteract effects of the predicted amounts of glucose, and affecting insulin therapy based on outputting information indicative of the determined one or more amounts of insulin.

  • Patent number: 11904139
    Abstract: A processor-implemented method for closed-loop control in steady-state conditions includes determining, based on data including historical bolus information but excluding historical basal information, an amount of unmetabolized therapeutic substance in a patient; determining, based on a difference between a most recent measurement of a physiological condition of the patient and a target value for the physiological condition, a first amount or rate of a basal dosage for delivery to the patient; adjusting, based on the amount of unmetabolized therapeutic substance, the first amount or rate of the basal dosage to determine a second amount or rate of the basal dosage; and causing delivery of the second amount or rate of the basal dosage based on communicating the second amount or rate in a delivery command.

  • Patent number: 11904140
    Abstract: The exemplary embodiments provide medicament delivery devices that use cost functions in their control systems to determine medicament dosages. The cost function may have a medicament cost component and a performance cost component. The exemplary embodiments may use cost functions having medicament cost components that scale asymmetrically for different ranges of inputs (i.e., different candidate medicament dosages). The variance in scaling for different input ranges provides added flexibility to tailor the medicament cost component to the user and thus provide better management of medicament delivery to the user and better conformance to a performance target. The exemplary embodiments may use a cost function that has a medicament cost component (such as an insulin cost component) of zero for candidate dosages for a range of candidate dosages (e.g., below a reference dosage).

  • Patent number: 11904143
    Abstract: An injector includes a housing having a syringe assembly and an actuating mechanism at least partially disposed within the housing. The syringe assembly includes a syringe barrel that stores a medicament to be injected into a user, a needle assembly, and a filter member disposed adjacent to the needle assembly. The actuating mechanism is operatively coupled to the syringe assembly and includes a torque spring that exerts a torque to urge the medicament through the filter member to be injected into the user. The actuating mechanism further includes a damper mechanism that exerts an opposing force to dampen the motion exerted by the torque spring.
