  • Patent number: 10952758
    Abstract: A method of removing a kidney stone from the kidney and ureter of a human includes the steps of introducing a laminar flowing fluid via a ureteroscope into the ureter or kidney and proximal the kidney stone and flowing inward toward the kidney and then switching the laminar flow to a turbulent flow which causes a reverse flow that moves the kidney stone in a direction away from the kidney and down the ureter toward the bladder where the stone may be removed using a wire basket. In one step the kidney stone may first be fragmented into smaller kidney stones or fragments prior to switching to the turbulent flow.

    Abstract: Each arterial bifurcation lesion has a fingerprint-like pattern related to varying amounts of plaque and degree of obstruction in the main vessel proximal to, within the bifurcation itself, and the distal limbs of the main branch and side branch(es) and related to the angle of the bifurcation. A new device and with it a new technique is described to optimize treatment of bifurcation (and trifurcation) lesions. The invention and related method use a catheter capable of delivering two or more guide wires exiting at the distal end of the catheter allowing treatment of lesions more safely and efficaciously. Safety is increased by allowing both guide wires to remain in place throughout the entire procedure. Efficacy is increased, particularly in the long-term, by providing a result that maximizes vessel coverage and normal flow dynamics in the entire bifurcation area.

Consequently, upon removal of the cannula (16), there is essentially no “drumming” or creation of friction-induced negative pressures sufficient to generate blood reflux. The preloaded septum body (64) also has its proximal surface (74) essentially flush and coplanar with the adjacent proximal end (66b) of the tubular septum holder (66) to enhance the cleanliness of the unit (24).

The proximal case portion includes an axially-extending boss that projects distally, with a portion of a distal end of the boss contacting the flow control valve. The valve permits fluid flowing in a distal direction to pass through the slit. Fluid flowing in a proximal direction, however, causes the valve to compresses against the boss and the slit to close, thus restricting fluid flow in a proximal direction.

In other embodiments, the adaptor includes a fluid release opening in fluid communication with the connection port extending generally radially through the adaptor body at a location spaced from the longitudinal ends of the body.

  • Patent number: 8771217
    Abstract: Shunt devices and a method for continuously decompressing elevated intraocular pressure in eyes affected by glaucoma by diverting excess aqueous humor from the anterior chamber of the eye into Schlemm's canal where post-operative patency can be maintained with an indwelling shunt device which surgically connects the canal with the anterior chamber. The shunt devices provide uni- or bi-directional flow of aqueous humor into Schlemm's canal.

  • Publication number: 20140128820
    Abstract: A medical catheter assembly includes a catheter hub, an elongate catheter member extending from the catheter hub and having at least one longitudinal lumen for passage of fluids, an extension tube extending from the catheter hub and defining an internal lumen in fluid communication with the at least one longitudinal lumen of the catheter member and a clamp positionable about the extension tube. The catheter hub defines a reduced profile to facilitate passage of the catheter hub through a surgical tunnel. The clamp includes first and second clamp sections and defines a longitudinal clamp axis. The clamp has a longitudinal opening for passage of the extension tube and a movable member adapted to move from a first position to a second position to substantially close the internal lumen. The first and second clamp sections are separable to facilitate transverse positioning of the clamp sections about the extension tube.

  • Patent number: 8617139
    Abstract: Disclosed are devices, methods and systems for treatment of eye disease such as glaucoma. Implants are described herein that enhance aqueous flow through the normal outflow system of the eye with minimal to no complications. The implant can be reversibly deformed to a first shape, such as a generally linear shape conducive to insertion. Upon insertion, the implant can deform to a second shape, such as a generally non-linear shape conducive to retention within the eye. The shape also improves fluid flow from the anterior chamber and prevents or reduces clogging.

  • Patent number: 8574203
    Abstract: A flushable catheter assembly having features to enable selective activation of fluid flow through the catheter assembly is disclosed herein. A septum is placed within the catheter adapter of the catheter assembly and includes a pathway that is closed prior to being biased open via a septum activator also positioned within the catheter adapter. A plurality of air vent channels is interposed between the septum and the inner surface of the catheter adapter to permit “flashback” of blood during insertion of the catheter into a patient. The septum activator is advanced through the pathway of the septum as a coupler is attached to a proximal opening of the catheter adapter.

  • Patent number: 8512360
    Abstract: Methods and devices for placing a target vessel in fluid communication with a source of blood and a target vessel. A conduit includes first portion adapted to be placed in fluid communication with a source of blood, such as a heart chamber, and a second portion adapted to be placed in fluid communication with a target vessel having a lumen, such as coronary artery. The first and second conduit portions are transverse to each other such that the conduit is generally T-shaped. The conduit lies on an exterior of the heart between the blood source and the target vessel and is configured to deliver blood in multiple directions into the lumen of the target vessel. For example, in an occluded coronary artery, blood flows both toward and away from the occlusion. The conduit may be flexible, rigid, collapsible or non-collapsible, and may be formed of synthetic vascular graft material, tissue, or a combination of the two.
