  • Patent number: 10098656
    Abstract: Embodiments of the present invention provide improved methods and apparatus of treating the prostate. In many embodiments, at least a portion of the prostate is enucleated with a water jet, in order to decrease the invasiveness of the surgery. The access to the prostate can be provided with one or more of open surgical access, percutaneous access, or urethral access. The prostate can be enucleated such that an inner portion of the prostate comprising adenomatous tissue of the prostate is separated from a portion an outer the prostate comprising the capsule. In many embodiments, the patient is treated with energy of the water jet configured to separate the capsule from the inner tissue of the prostate and to inhibit cutting of blood vessels.

    Abstract: A tubular structure comprising multiple overlapping layers surrounding a lumen has flexibility and structural integrity by allowing portions of the layers to slip relative to each other. One embodiment includes a support layer having a wired coil, braid or weave support element underlies at least one overlying layer. The support layer is fixed to the overlying layer at a bonding point and the remaining portion of the support layer is not fixed to the overlying layer, i.e. “free portion”. The support layer is permitted to slip at the free portion of the support layer, relative to the overlying layer. Further flexibility may be provided by a coil element of the support layer having substantial gaps between the loops of the coil to impart high flexibility of the tubular structure.

    Abstract: Devices, systems, and methods for treatment of an eye alter aspiration flow from the eye in response to an occlusion of the aspiration conduit pathway. Where aspiration is drawn from the eye using a volumetric pump, the pump can be reversed so as to induce fluid reflux from the aspiration conduit pathway into the eye to help clear the occlusion. The pump may vary the reverse flow in response to sensed aspiration pressure or the like, and the reverse flow may be halted before the pressure within the aspiration conduit pathway adjacent the eye significantly exceeds the irrigation fluid pressure and/or the pressure within the eye. Reflux may alternatively be generated by modulating a vent valve disposed between an irrigation conduit pathway and the aspiration conduit pathway.

  • Patent number: 9943329
    Abstract: A tissue-removing catheter includes a cutting element. A radially innermost portion of the leading radial wall of a raised element of the cutting element may be spaced a radial distance from the longitudinal axis that is less than 66% of the radius of the annular cutting edge. The cutting element may be extendable through the window during operation such that as the cutting element is being rotated about its longitudinal axis, less than an entire radial portion of the leading radial wall passes through the window. A plurality of abrading members may be formed on at least the central portion of the inner surface of the cutting element to abrade hardened tissue as the cutting element is rotating about its longitudinal axis. A radially outermost portion of the leading radial edge of the raised element may be spaced apart radially from an inner surface of the cutting element.

  • Patent number: 9931161
    Abstract: An energy delivery probe for use in tissue ablation and method of use is presented. The energy delivery device has at least a first energy delivery member and a second energy delivery member that have handle members positioned along a longitudinal axis, each handle member having a proximal and distal end. The distal end of the first handle member is releasably coupled to the proximal end of the second handle member and a portion of each member is defined in a coaxially surrounding relationship to each other along the longitudinal axis. The method of using the probe involves identifying a tissue to be ablated, providing the energy delivery probe, inserting at least a portion of the energy delivery probe into the identified tissue, delivering electrical energy through the energy delivery probe to the identified tissue, and ablating the identified tissue such that at least a first ablation zone is formed.

    Abstract: A phacoemulsification irrigation sleeve having a body configured to operatively connect to a phacoemulsification needle. The body has proximal and distal ends and defines a passageway for liquid. A first irrigation port is formed in the body between its proximal and distal ends. The body is slit to define a first flap configured to swing away from the first irrigation port in response to pressure of fluid flowing in the passageway to thereby reduce resistance of fluid flow through the first irrigation port. The first flap, when swung away from the first irrigation port, is oriented to direct fluid flowing through the first irrigation port in a direction from the proximal end of the body toward the distal end of the body.
