  • Patent number: 11957853
    Abstract: Various embodiments disclosed relate to drug-coated balloon catheters for treating, preventing, or reducing the recurrence of a stricture and/or cancer, or for treating benign prostatic hyperplasia (BPH), in a non-vascular body lumen and methods of using the same. A drug-coated balloon catheter for delivering a therapeutic agent to a target site of a body lumen stricture includes an elongated balloon having a main diameter. The balloon catheter includes a coating layer overlying an exterior surface of the balloon. The coating layer includes one or more water-soluble additives and an initial drug load of a therapeutic agent. In some embodiments, the balloon catheter includes a length-control mechanism which stretches and elongates the balloon when it is in a deflated state, giving the balloon a smaller cross-sectional deflated profile for tracking through the body lumen and for removal after treatment.

  • Patent number: 11955117
    Abstract: A system and method are provided for analyzing and reacting to interactions between entities using electronic communication channels. The method includes receiving, via the communications module, data captured from a conversational exchange between a first entity communicating with a second entity using an electronic communication channel. The method also includes analyzing the captured data to detect an indication that the first entity is or was distracted during the conversational exchange, is or was disinterested in a portion of the conversational exchange or missed the portion of the conversational exchange. The method also includes determining based on the indication an action to address the distraction during, disinterest in, or missing of, the portion of the conversational exchange; and providing, via the communications module, an automated message to at least one of the first entity and the second entity for executing the action.

  • Patent number: 11946731
    Abstract: An arrow head cluster is created utilizing an injection mold. An upper cluster cavity is formed in an upper die member and a lower cluster cavity is created in a lower die member. The upper and lower cluster cavities, when joined create a cluster cavity. The cluster cavity is used to create the arrow head cluster, after molten material is injected into the injection mold. The cluster cavity includes a plurality of chambers for creating a plurality of arrow heads. The plurality of chambers are connected to each other with a plurality of flow channels and a support frame. The injected material includes metals, ceramic and plastic. The materials are injected into the cluster cavity through the plurality of flow channels. The plurality of flow channels allow the material to flow evenly through the plurality of cluster cavities.

  • Patent number: 11874085
    Abstract: A trigger-traverse crossbow. The crossbow has a trigger latch block slidingly connected to the flight track. The trigger latch block is configured to engage and retain the bowstring. A cocking mechanism is configured to draw the trigger latch block with the bowstring from an initial position near a forward end of the flight track to a cocked position. A one-way retention mechanism is configured to immobilize the trigger latch block against linear movement in a forward direction along the flight track. A trigger-traverse mechanism is configured to slide the trigger latch block in a forward direction to its initial position after the bowstring is released. In one embodiment, the cocking mechanism includes a cocking lever pivotally connected to the crossbow body along with one pair or two pairs of cocking hooks that move in response to the rotation of the cocking lever.

  • Patent number: 11828565
    Abstract: A repeating crossbow having a pump-action reloading mechanism. The crossbow includes an elongated body with a shooting track and a holding chamber configured to house one or more projectiles. A hatch is coupled to the body and configured to move between a first position aligned with the shooting track and a second position at least partially aligned with the holding chamber. A palm rest is slidingly connected to the elongated body. Sliding the palm rest in a rearward direction causes the hatch to move from the first position into the second position. A biasing member within the holding chamber ejects a projectile onto the hatch. Sliding the palm rest in a forward direction to return to its default position causes the hatch to return to its first position, bringing the projectile into alignment with the shooting track.

  • Patent number: 11815326
    Abstract: An improved slingshot band having a tapered outer contour. The slingshot band has a tubular body having a first fork end and a second pouch end. The tubular body comprises a first layer of an elastic polymer. The first layer has a constant thickness. The tubular body further comprises a second layer of an elastic polymer. The second layer has a greater thickness near the fork end of the tubular body and lower thickness near the pouch end of the tubular body. The increased thickness of the section of the tubular body near the fork end of the slingshot band reinforces the most vulnerable section of the slingshot band against failure, thereby extending its longevity.

  • Patent number: 11768052
    Abstract: A break action pistol crossbow having a repeating capability. The crossbow has a loading chamber configured to house a plurality of bolts. A biasing mechanism is disposed within the loading chamber. The crossbow has a forward retainer positioned at the front of a flight rail and a rear retainer positioned at the back of the flight rail. The bowstring is configured to be drawn over a bolt loaded into the chamber. As the bowstring travels over the bolt, the biasing mechanism presses the bolt against the bowstring. When the bowstring clears the bolt, the force applied onto the bolt by the biasing mechanism presses the leading end of the bolt against the retaining bridge and presses the trailing end of the bolt against retaining brush. In this manner, the bolt is aligned with the flight rail.

  • Patent number: 11680767
    Abstract: A multi-stroke lever action crossbow has two sets of cocking hooks. The first cocking hooks are disposed on cocking links slidingly coupled to a crossbow body. The second cocking hooks are retractable. The second cocking hooks are disposed on a cocking arm, which is pivotally attached to a cocking lever. A retractable handover latch operatively engages the cocking arm. During the first stroke of the cocking lever, the first cocking hooks draw the bowstring past the handover latch, where the bowstring is retained in a partially drawn position. During the second stroke of the cocking lever, the second cocking hooks draw the bowstring past a trigger latch, where the bowstring is retained in a fully drawn position. When the cocking lever returns to its initial closed position, the second cocking hooks and the handover latch are retracted into the crossbow body.
