Puncturing Or Piercing Patents (Class 606/185)
  • Patent number: 10285682
    Abstract: A medical device and treatment method are configured to form a hole as a passage, which is used for treatment, in biological tissues without puncturing the biological tissue and while reducing the influence on a living body The medical device includes: a shaft portion which is elongated, a pressing portion on a distal side of the shaft portion to press the tissue, and a thrusting portion provided further on the distal side of the shaft portion than the pressing portion and configured to be thrust into a joint portion of the tissue. When pressing the biological tissue using the pressing portion, a direction from the shaft portion to the pressing portion and a direction from the shaft portion to the thrusting portion are different from each other, and the pressing portion can be expanded and contracted in an expansion direction intersecting a shaft center direction of the shaft portion.

A catheter extends from outside the patient's body through a major blood vessel and the patient's aortal valve into the left ventricle. The catheter has an external sheath, an outer tubular shaft onto which proximal ends of the shape-retaining wires are affixed, and a middle shaft extending through the hollow core of the outer shaft and which is affixed to a central shaft of the capsule. A control console has mechanical geared drives coupled to the outer and middle catheter shafts within the catheter.

  • Patent number: 9592153
    Abstract: A method is described for treating glaucoma by surgically implanting a shape recoverable member in the sclera of the eye. The shape recovery member is adapted to recover involutely when shape recovery is caused to occur. The bending of the shape recoverable member during its recovery exerts pressure on longitudinal ciliary muscle to supply tension to and open the trabecular meshwork. As a result, aqueous humor flows more freely and reduces the intraocular pressure.

The tip has a blunt point and a pair of shorter side surfaces separated by a relatively longer pair of opposing surfaces to form in radial cross-section a geometric shape that has a longer length and relatively narrower width. The side surfaces and opposing surfaces terminate in end surfaces located proximally from the blunt point. The end surfaces extend radially outwardly from opposite locations of the outer surface. A conical surface facilitates initial insertion of the obturator and the geometric shape facilitates separation of consecutive layers of muscle tissue having fibers oriented in different directions and provides proper alignment of the tip between the layers of muscle.

    Abstract: For cricothyrotomy and the like, a surgical device has, in one embodiment, a device body with a bi-directional scalpel, an end cap, and a tracheal hook that fits within a channel formed in the device body. With the end cap removed to expose the bi-directional scalpel blade and with the tracheal hook fully inserted within the body channel, the device can be held, e.g., in the dominant hand of an operator, and manipulated to make an opening in the patient's neck using the exposed scalpel blade. The tracheal hook can then be slid away from the device body with the hook's barbed tip entering the opening to enable the operator to easily and quickly secure the surgical airway. The design of the surgical device enables an economy of movements that otherwise would typically not be within the skill set of an operator who was not a surgeon.

  • Patent number: 9067063
    Abstract: Brachytherapy treatment apparatus are provided that include an elongate core member, a plurality of expandable catheters or other elongate members and a balloon or other expandable member on a distal portion adjacent the core member. Each catheter includes a distal end coupled to the core member distal end, a proximal end movable relative to the core member, and a lumen extending between the proximal and distal ends for receiving a source of radiation therealong. The balloon is expandable independently of the catheters such that the balloon may be expanded after expanding the catheters, e.g., to facilitate imaging and/or dose planning. Optionally, a working channel may be provided for receiving an aspiration catheter or other instrument or at least one of the catheters may include an aspiration lumen and one or more ports, e.g., for aspirating material from a region surrounding the distal portion.

  • Patent number: 9039723
    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.

  • Patent number: 9039701
    Abstract: System and methods are shown having a tube-within-tube assembly with a deployable curved deflectable tube or cannula that deploys from a straight cannula or trocar. The curved cannula has a pre-curved distal end to create an angular range of 0° to 180° when fully deployed from the straight trocar. The curve is configured such that the flexible element carrying a treatment device can navigate through the angular range of deployment of the curved cannula. The curved cannula allows the flexible element to navigate through a curve within bone without veering off towards an unintended direction.

  • Publication number: 20150126842
    Abstract: A needle electrode is provided incorporating a protective flap and optionally a retraction chamber. By providing an impenetrable barrier covering the area of skin over the needle's tip, the protective flap protects against needle sticks that can occur when the tip of a needle electrode is pushed back out through the skin. An adhesive layer on the skin-side of the protective flap secures the needle in place without the use of a separate piece of adhesive tape. Other types of needles can incorporate flaps for protection or for securing the needle to the patient.
