  • Patent number: 10441153
    Abstract: An endoscope particularly suited for endocranial procedures and a method of using the endoscope. In some examples the endoscope is rigid except for a bend/tilt portion near a distal end of a rigid tube that is inserted in a patient's cranium, which distal end is controlled in a degree and direction of tilt with a finger operated controller at the endoscope's handle. Some examples use telescoping tubes that allow customizing the endoscope size for specific procedures. A distal portion of the endoscope can be disposable, supplied in a sterile package for a single procedure, thus taking into account contamination dangers that are particularly high for intracranial and certain other interventions and the fact that it can be difficult or impossible to effectively autoclave heat-sensitive components of certain endoscopes or effectively sterilize them using other techniques.

  • Patent number: 10307340
    Abstract: An occlusion clearing device for a patient has a housing with a motor(s) that generates repetitive motion, which is reciprocating, rotational or both. A clearing stem including a sheath that has a lumen, wherein aspiration is conducted through the sheath lumen. A wire is located in the sheath lumen and receives repetitive motion from the controller. The sheath terminates in a sheath end having at least one sheath opening. The wire terminates in a wire tip, which may be flat, helical, or tubular. The wire tip is positioned within the sheath end, in proximity to the sheath opening(s), and movement of the wire tip and/or sheath end relative to each other creates shearing forces that break up an adjacent occlusion.

  • Patent number: 8894679
    Abstract: A surgical device mitigates over-puncture with a bias spring that biases a leading, cutting edge in the opposite direction of the anticipated over-puncture. An associated locking mechanism is configured to release the force of the bias spring in a direction counter to the direction of insertion when the tension force of tissue against the cutting edge is released. Thus, when an opening in the tissue forms, the tension is released and the cutting edge can move opposite to the direction of insertion of the surgical device at the same time that an applied force drives the instrument in the direction of insertion. In this manner, the spring and locking mechanism cooperate to move the cutting edge opposite to the direction of insertion as soon as an incision is made.

    Abstract: A catheter system including an insertion device and a catheter device. The insertion device includes a housing, a latch, a needle for insertion into a patient; and a spring. The catheter device includes a housing comprising a chamber, and a seal disposed in said chamber. The seal is configured to reseal when the needle is withdrawn from the seal such that blood is sealed in the chamber. The spring relaxes and thereby retracts the needle entirely into the housing of the insertion device when the latch decouples from the catheter device.

  • Patent number: 8715242
    Abstract: Devices and methods are provided for inserting a sterile catheter, and for maintaining a sterilely sealed catheter and catheter insertion site over time. In one embodiment, a four-part integrated system is provided that includes (1) a novel vascular catheter with integrated uniform diameter mounting, capping, and needle safety procurement features, (2) a novel vascular catheter dressing designed to specifically mate with and seal to this vascular catheter to achieve a sterile seal both at the catheter-skin insertion site and the catheter-dressing exit site, (3) a hub protection and sterilizing apparatus that serves to stabilize, protect, and sterilize the working end of the catheter hub as it protrudes from the sterile dressing, and that also helps to improve the ergonomics of the catheter-dressing complex in order to avoid snagging on clothing etc., and (4) a whole dressing accessory secondary cover and securement device.

  • Patent number: 8622967
    Abstract: An intravenous catheter device is provided which includes a catheter adapter having a fluid chamber, a needle adapter being slidably positioned within the fluid chamber, the needle adapter supporting a base of an introducer needle and a terminal end of a section of intravenous tubing such that a fluid pathway of the introducer needle is in fluid communication with a fluid pathway of the section of intravenous tubing. Following catheterization, the needle adapter is slid to a preferred proximal position whereby a sharpened tip of the introducer needle is shielded within a catheter of the intravenous catheter device, or a portion of the fluid chamber of the catheter adapter. When in the preferred proximal position, fluid communication between the catheter and a section of intravenous tubing is facilitated via the hollow body of the introducer needle.

  • Patent number: 8608697
    Abstract: A method and apparatus are provided for a fluid level insertion indicator that provides immediate feedback to a surgeon by draining when a tip of a needle has entered a body lumen, such as peritoneal cavity. An apparatus includes a handle connected to a hollow needle and a hollow stylet that extends through the hollow needle and has a blunt distal end that includes an opening for passing fluid. A spring biases the stylet to extend past the sharp distal end of the needle absent resistance by tissue against the stylet. An at least partially translucent pressure chamber configured to hold a quantity of fluid under pressure is connected to the proximal end of the stylet. The pressure chamber and stylet form a conduit for passing fluid through the opening in the blunt distal end when the stylet extends past the sharp distal end of the hollow needle.
