  • Patent number: 11253293
    Abstract: A fluid vessel insertion device (10), typically for medical use, comprises a puncture member (18) arranged for locaton within a sleeve (20), and a retraction mechanism (44, 48, 60) for retracting the puncture member relative to the sleeve. The puncture member (18) is retractable in use between a first condition in which an end (18A) of the puncture member protrudes beyond an end (24) of the sleeve and a second condition in which the end of the puncture member is within the sleeve (20). The retraction mechanism (44, 48, 60) actuates the puncture member between the first and second conditions in response to fluid pressure at the end (18A) of the puncture member. The device may be used during positioning of the sleeve in a desired fluid vessel, such as, for example, during intravenous cannulation.

  • Patent number: 11207060
    Abstract: Systems, methods and compositions relating to delivering synthetic polymer formulations to the body are described, which can be used by a range of medical personnel including those with minimal experience and training. Under some embodiments, the present invention relates to systems and devices for delivering polymer formulations to a body cavity (e.g. peritoneal cavity) to reduce or stop bleeding. Under some embodiments, an initial percutaneous access pathway is first formed using a delivery device with a probe and needle mechanism that automatically stops the advance of the device upon insertion into a body cavity or space, thus minimizing user error and improving patient safety. The hollow probe then allows transmission of polymer, mixed with gas and/or additional substances, from a holding chamber or canister to flow through the device and hollow probe into the patient's anatomic cavity or space of interest, stopping expansion when the device senses the appropriate pressure.

    Abstract: Apparatus and methods for sealing a puncture through tissue includes an introducer sheath sized for introduction into a puncture, cartridge sized for insertion into the introducer carrying a sealant, and a locking element for coupling the introducer sheath to the cartridge. When the cartridge is advanced into the introducer sheath, the locking element couples the introducer sheath to the cartridge such that subsequent retraction of the cartridge causes the introducer sheath to retract, thereby deploying the sealant from the cartridge within the puncture beyond the introducer sheath.

  • Patent number: 10492811
    Abstract: An endoscopic includes a handle, a tubular member, a control member, and an end effector assembly. The handle has a stationary member and a movable member. The movable member includes a constrained curved path for passage of the control member. The tubular member has an end coupled to the stationary member and a distal end rotatably coupled to the end effector assembly. The control member extends through the curved path, the tubular member, and is coupled to the end effector assembly. A knob is attached to the movable member and control member. Displacement of the movable member relative to the stationary member causes actuation of the end effector assembly, and rotation of the knob on the movable member causes the control member to rotate within both the constrained curved path and the tubular member, and results in rotation of the end effector assembly.

  • Patent number: 10478109
    Abstract: A fluid transfer device for parenterally transferring fluid to and/or from a patient includes a housing, a needle, and an occlusion mechanism. The housing defines a fluid flow path and is couplable to a fluid reservoir. The needle has a distal end portion that is configured to be inserted into the patient and a proximal end portion that is configured to be fluidically coupled to the fluid flow path of the housing, and defines a lumen therebetween. The occlusion mechanism selectively controls a fluid flow between the needle and the fluid flow path. The occlusion mechanism includes an occlusion member that is movable between a first configuration where the lumen of the needle is obstructed during insertion into the patient and a second configuration where the lumen of the needle is unobstructed after the needle has been inserted into the patient allowing fluid transfer to or from the patient.

  • Patent number: 10328239
    Abstract: A catheter insertion device and method for insertion. The catheter insertion device can include a housing, a needle attached to a needle carrier, a catheter including a catheter shaft attached to a catheter hub, and a guidewire. The guidewire can include a coil tip positioned in a lumen of the needle. The method for insertion can include inserting a distal end of the needle and the catheter shaft into a blood vessel of a patient, advancing the coil tip out of the needle lumen and into the blood vessel, advancing the catheter over the guidewire, and withdrawing the guidewire and the needle from the catheter. The coil tip can include a straightened configuration and a coiled configuration. The coil tip can transition from the straightened configuration in the needle lumen to the coiled configuration in the blood vessel.

  • Patent number: 10265097
    Abstract: The disclosure relates to a needle assembly for delivering a lead and methods of use. The needle assembly is configured to cut tissue and reduce the potential for cutting vulnerable bodily structures. The needle assembly includes an outer needle with a blunt tip and an inner needle with a sharp tip. The outer needle may be curved, and the inner needle may be curved. When the inner needle is rotated with respect to the outer needle, the inner needle protracts or retracts with respect to the outer needle. A stopping feature on the needle assembly may be included to resist over-rotation or over-extension. The needle assembly provides an initial path that may be further dilated for delivering a lead, such as a vagus nerve stimulation lead to a target site. The target site may be electrically tested with some embodiments.
