  • Patent number: 8147480
    Abstract: A therapeutic agent delivery system that includes a catheter having a proximal end and an opposite distal end. The catheter has a body with a lumen defined therein. The body of the catheter includes a non-bulbous region having a substantially uniform outer diameter and a bulbous region made from an elastically deformable material. While in a first state the bulbous region has a maximum outer diameter greater than the substantially uniform outer diameter of the non-bulbous region; and while in a second state the maximum outer diameter of the bulbous region is reduced relative to that while in the first state.

  • Patent number: 8092431
    Abstract: The present disclosure relates to a seal assembly for a cannula. The cannula includes a housing having a proximal portion and a distal portion. The seal assembly is located in the proximal portion of the housing and includes a first seal including a first tri-slit, a second seal disposed co-axially and proximal to the first seal and including a second tri-slit, and a third seal disposed co-axially to the first seal and the second seal and including a central opening. A cap is coupled to the proximal portion of the housing and adjacent the third seal and includes a plurality of suture retaining features, such as tabs, for management of sutures during surgery. Fluid leakage out of the cannula, during surgery, is substantially reduced due to the leakage being limited to a channel defined by the first tri-slit, the second tri-slit, and the central opening.

  • Patent number: 8088111
    Abstract: A needle shroud assembly (10) comprises a barrel (16), a needle shroud (18) captively telescoped relative to the forward end of the barrel for movement between retracted and extended positions and is biased towards said extended position by a spring (25). A separate locking element (42) is mounted within the barrel moveable between a safe position (as seen in FIG. 5) in which it prevents or limits retraction movement of said needle shroud (18), and a live position in which it is clear of the rearward path of the needle shroud (18). The locking member is moved from its safe position to its live position by means of an externally operable actuating member (54), having a cam (52) which cooperates with a cam surface (46) on the locking element (42). The cam (52) is driven back to its original position by the rearward end of the shroud (18) as it moves to the fully retracted position.

  • Patent number: 8083707
    Abstract: Ultrasonic, sonic or vibratory energy, delivered non-invasively, minimally invasively or invasively (e.g. surgically), is utilized to provide direct cleaning action at or to the location of the implanted device such as a prosthetic heart valve with undesirable deposits of at least some amount thereon or therein. Such ultra-sound energy may be aided by the use of a drug in association or cooperation with the acoustic irradiation. The “cleaning” acoustic energy may optionally be delivered under the guidance of an imaging modality and may be delivered in a timed or gated manner such that the valve occluders or leaflets are in a preferred position (assuming they are functioning) during exposures.

  • Patent number: 8083720
    Abstract: A device, system and method deliver an agent to a soft mass, such as an area of the body, and more specifically the brain. One aspect includes creation of one or more channels, tunnels or grooves in tissue using a relatively small diameter, minimally-invasive stylet and then removing the stylet prior to infusion. The stylet-created channels become paths of increased hydraulic conductivity, through which the infusate will tend to flow and produce a predictable infusion pattern. Infusate will be carried into these channels with relatively low resistance, and then infuse outward from these channels into the surrounding tissue. By carefully positioning these channels, one can control and modify the preferred paths and duration of distribution.

  • Patent number: 8070733
    Abstract: A device for regulating the flow rate of a medical liquid includes a body provided with elements associated with corresponding parts connected together but torsionally free, at least one of the parts including a plurality of recesses acting as flow regulator able to modify the flow rate of the liquid directed towards the patient by rotating the parts about a common axis of rotation. Between the parts a seal element enables the recesses to be selectively connected together via communication elements, so achieving flow rate regulation. Transverse sealers are provided between the seal element and at least the second part of the parts which are interconnected but torsionally free. The transverse sealers preventing the escape of liquid from the recesses and from the body of the device following a relative movement or misalignment between the parts in a plane perpendicular to the axis of rotation or along this latter during flow regulation or following any angular misalignment of the parts relative to the axis.

  • Patent number: 8070732
    Abstract: A holding device for locking the head of a syringe piston on a pusher has arms connected to respective pinions pivotable and translationally displaceable so that the corresponding arm is involved in the same motion between a rest position, in which the arms are closed and pressed against the pusher, and an open position, in which the arms are opened and remote therefrom, the translation is carried out prior to rotation during the movement toward the open position or in reverse order toward the rest position. The holding device also has a control member and means for converting a part of the control member movement by transmitting it to at least one pinion as a translation movement, which are translationally locked, and means for converting a part of the control member movement by transmitting it to at least one pinion as a rotation movement.

  • Patent number: 8052651
    Abstract: An apparatus and method for securing a catheter within a target area of the anatomy are disclosed. The catheter includes a passage or opening through which a suture filament may be routed. The suture filament can be secured relative to anatomical tissue to retain the catheter within a desired region. After the catheter has been used to complete the desired medical procedure, the suture filament may be released, permitting the catheter to be easily withdrawn from the anatomy. The catheter may include a biodegradable tip, which when absorbed by the body would enable the catheter to be removed. Biodegradable suture filaments and other components may also be used to facilitate the release of the catheter from the anatomy.

  • Patent number: 8052654
    Abstract: A syringe (10) has a plunger (20), a barrel (11) and a collar (40, 50) with two pawls (42A, 42B). The plunger has two opposed ratchets (23A, 23B) that align with the one each of the pawls and thereby or impede, withdrawal of the plunger during or following depression of the plunger. The barrel has a collar with an inner (50) and an outer member (40) that are incapable of rotation relative with respect to each other. The outer member has the two pawls (42A, 42B) and two fingers that slidably engage opposed guide slots (28) on the plunger to thereby prevent or minimize rotation of the plunger relative to the collar. The inner member of the collar is operable to prevent engagement of the plunger ratchet by the two pawls until the plunger is depressed.
