  • Patent number: 11964136
    Abstract: Medical devices for delivering a plug to a void within a patient. The medical device can include a fluid delivery device and a plug holder (e.g., a plug delivery device) coupled to a distal end of the fluid delivery device. The medical device may be configured such that the delivery of fluid from the fluid delivery device wets the plug, ejects the plug from the plug holder, and pushes the plug through a lumen of an elongate tube to a void within a patient.

  • Publication number: 20240001037
    Abstract: Coverings for syringe plunger tips, as well as syringes and syringe components including such coverings, are disclosed. A material of the covering may have at least one different material property than a material of the plunger tip. The coverings may provide a reduced coefficient of friction between the covering and a surface of the syringe relative to the coefficient of friction between the plunger tip and the syringe surface. The coverings may also isolate a substance loaded in the syringe from the plunger tip. The coverings may include a locking member to lock the covering over the plunger tip. Methods for manufacturing a syringe assembly including such coverings are also disclosed.

  • Publication number: 20230372052
    Abstract: A device, and related systems and methods, for inserting a marker into a patient's body. The device may comprise a retention mechanism to hold the device in a first, undeployed, state. The device may be inserted into a patient's body in the first state, transitioned by the user into a second state wherein the retention mechanism is overcome, and then transition the device into a third state to deliver a marker to a precise location. The device may then be removed from the patient's body.

  • Patent number: 11751859
    Abstract: Medical devices for delivering compositions or medical articles to a patient are disclosed. The medical plug delivery devices can include a fluid delivery device (e.g., a syringe), a frame, and a rotatable magazine. The rotatable magazine can include a plurality of chambers that each hold a composition or a medical article (e.g., a medical plug). By rotating the rotatable magazine relative to the frame, material within the chambers of the rotatable magazine can be sequentially deployed to a patient.

  • Publication number: 20230146392
    Abstract: Coatings for syringe plunger tips, as well as syringes and syringe components including such coatings, are disclosed. A material of the coating may have at least one different material property than a material of the syringe component to which it is applied. The coatings may provide a reduced coefficient of friction between the coating and a surface of the syringe relative to the coefficient of friction between the uncoated component and the syringe surface. Methods for manufacturing a syringe or syringe component including such coatings, as well as methods for isolating a substance in a syringe from a syringe component, are also disclosed.

  • Publication number: 20230098300
    Abstract: Devices, systems, and methods used to deploy a localization device into a target lesion are disclosed. The system includes a delivery device configurable in a ready-to-deploy state and a deployed state. When the delivery device is in the ready-to-deploy state, biased engagement members are engaged with proximal detents of a handle of the delivery device. When the delivery device is in the deployed state, the biased engagement members are engaged with distal detents. The delivery device is transitioned from the ready-to-deploy state to the deployed state by distal displacement of a plunger relative to the handle. The localization device is deployed from a cannula of the delivery device into the target lesion when the delivery device transitions from the ready-to-deploy state to the deployed state.
