  • Patent number: 9301756
    Abstract: Surgical coils are disclosed for marking, anchoring, stapling and suturing. Such surgical coils may be implanted in the body by deforming them to a small cross section profile, sliding them through a low profile delivery device then deploying them from an embodiment of a delivery device at a targeted site. Embodiments of surgical coils when deployed revert back to a coiled configuration and circle tissue at the target site. Such surgical coils may be deployed about attachment members, such as suture lines, marker lines and the like for anchoring same.

  • Patent number: 8337509
    Abstract: A cannula for an ocular implant delivery system. In some embodiments, the cannula includes a tubular member having a curved portion, a distal opening surrounded by a distal opening surface, and a distal tip, the distal tip being adapted to be inserted into an anterior chamber of a human subject's eye, through trabecular meshwork and into Schlemm's canal of the eye, a proximal portion of the tubular member being adapted to extend from a location exterior to the eye when the distal tip is in Schlemm's canal of the eye, the cannula being further adapted to cooperate with an advancement mechanism to advance an ocular implant through the tubular member toward and through the distal opening into Schlemm's canal of the eye when the distal tip is disposed in Schlemm's canal.

  • Patent number: 8029470
    Abstract: Systems and methods for penetrating a tissue membrane to gain access to a target site are disclosed. In some examples, systems and methods for accessing the left atrium from the right atrium of a patient's heart are carried out by puncturing the intra-atrial septal wall. One embodiment provides a system for transseptal cardiac access that includes a stabilizer sheath having a side port, a shaped guiding catheter configured to exit the side port and a tissue penetration member disposed within and extendable from the distal end of the guide catheter. The tissue penetration member may be configured to penetrate tissue upon rotation and may be coupled to a distal portion of a torqueable shaft. In some embodiments, the stabilizer sheath and shaped guiding catheter may be moved relative to the patient's body structure and relative to each other so that a desired approach angle may be obtained for the tissue penetration member with respect to the target tissue.

  • Patent number: 7967790
    Abstract: A hemostasis valve is disclosed herein. The hemostasis valve may include an inner bushing, a rotation sleeve, an elastomeric sleeve, and a biasing element. The rotation sleeve may extend about the inner bushing and be rotationally displaceable relative to the inner bushing. The elastomeric sleeve may include a first end operably coupled to the inner bushing, a second end operably coupled to the rotation sleeve, and an iris valve portion. Rotation of the rotation sleeve relative to the inner bushing may cause the iris valve to transition from an open state to a closed state. The biasing element may act between the rotation sleeve and inner bushing to bias the iris valve towards at least one of a closed state or an open state.

  • Patent number: 7890186
    Abstract: An anchoring device and a delivery method thereof can effectively provide a means for securing an implant to a wall of an internal organ within a patient in a variety of clinical applications. In one embodiment, an anchoring device used to retain a cardiac pressure measurement device is provided. The device is implanted in the body by deforming it to a small cross section profile, sliding it through a low profile delivery device and ejecting from the delivery device at a targeted site. The anchoring mechanism, when ejected from the delivery device, reverts back to pre-formed configuration and engages opposite sides of an organ wall, thereby anchoring the implant in the organ wall.

  • Publication number: 20110022057
    Abstract: A transfer guidewire assembly configured to manipulate an implanted elongate body includes a flexible elongate portion, such as a guidewire, and coupler. The flexible elongate body has a proximal end and a distal end attached to the coupler. The coupler can include a catheter and/or a handle. The handle can include a screw. The coupler is configured to be removably attached to the end of an implanted elongate body, for example, by forming an interference fit with the outside diameter of the implanted body. A method for transferring an end of an implanted medical component from first site to a second site within a patient, such as a pacemaker, defibrillator, and/or sensor lead, etc., includes inserting a guidewire into the body at the first site and externalizing the guidewire at the second site. A proximal portion of the implanted component near the first site and is attached to the guidewire.

In some examples, systems and methods for accessing the left atrium from the right atrium of a patient's heart are carried out by puncturing the intra-atrial septal wall. One embodiment provides a system for transseptal cardiac access that includes a guiding catheter, an access catheter and a guidewire. The access catheter may include a tissue penetration member disposed within a housing wherein the tissue penetration member is substantially contained within the housing when in a retracted configuration. When the distal end of the access catheter is disposed adjacent the septal wall, the user can initiate an actuator switch, which may be in a proximal portion of the system, to cause the tissue penetration member to extend through the septal wall.

  • Patent number: 7115052
    Abstract: Sport ball training devices and methods for releasably holding a tennis ball or other sport ball at an appropriate height for the practice of striking the ball, either directly or indirectly with a racket or the like. An embodiment may have a support device with a base and an adjustable vertical tubular assembly for the support of a transverse arm from which a ball sling is suspended. A retainer member of the ball sling circumferentially holds a sport ball. An embodiment of the retainer member may be made from an elastometric material that lightly squeezes the ball with sufficient force to restrain it, but releases easily when the ball is hit so that the trajectory of the ball is not affected by the presence of the retainer member nor is the racquet significantly affected by the presence of the ball sling generally.

  • Patent number: 6875182
    Abstract: Devices, methods and systems for obtaining biopsy tissue samples are provided. Flexible hollow tubes with a rail and a tip cutting element advance within a shaft with an aperture and a bore having a ramp, so that the cutting element emerges from the aperture and cuts tissue as it moves over the ramp. Either or both shaft and bore may have guides, which may engage each other to guide the tube along a tissue cutting pathway. A tube may have a rail and the bore a channel which engages the rail and guides the tube. Cut tissue may be acquired and transported proximally within the tube by suction to a tissue collection chamber. Multiple tissue samples may be obtained from a single insertion point by rotation and/or translation of the shaft between biopsies.
