Abstract: Systems for delivering a bifurcated stent to a bifurcation site include catheters and/or bifurcated systems delivered therefrom. A catheter includes a balloon with a bulge region that allows a portion of the stent to be expanded.

Abstract: A voice coil suspension system comprising a spider formed of flexible dielectric material defining a flexure portion configured to suspend a voice coil for axial displacement and an elongate connector portion for carrying flat electrical conductors for electrically connecting terminals of said voice coil to stationary electric contacts.

Abstract: A medical apparatus and method of use for implanting a catheter in a patient's body which catheter can be easily positioned, repositioned, and replaced. The apparatus includes an elongate sleeve intended to be subcutaneously implanted. The sleeve comprises a wall surrounding an interior elongate passageway which extends from a sleeve proximal end to a sleeve distal end. The sleeve outer peripheral surface carries a layer of porous material intended to be placed just under the patient's outer skin layer in contact with the dermis to promote tissue ingrowth for anchoring the sleeve and forming an infection resistant barrier. The sleeve passageway includes a sealing nib dimensioned to engage the outer surface of the catheter while permitting the catheter to slide relative to the sleeve. The sealing nib prevents deleterious material from migrating into the patient's body along the catheter outer surface.

Abstract: A medical apparatus and method of use for implanting a percutaneous catheter in a patient's body which catheter can be easily positioned, repositioned, and replaced. The apparatus includes an elongate sleeve comprising a wall surrounding an interior elongate passageway. The passageway extends from a sleeve proximal end to a sleeve distal end. The sleeve is intended to be percutaneously implanted through an incision in the patient's skin so that the sleeve distal end resides subcutaneously. The sleeve outer peripheral surface carries a layer of porous material intended to be placed just under the patient's outer skin layer in contact with the dermis to promote tissue ingrowth for anchoring the sleeve and forming an infection resistant barrier. The sleeve passageway is dimensioned to snugly accommodate the outer surface of catheter while permitting the catheter to slide relative to the sleeve.

The sleeve distal end outer surface carries porous material intended to contact the patient's dermis to promote tissue ingrowth. The sleeve passageway is dimensioned to snugly accommodate the outer surface of the catheter while permitting the catheter to slide relative to the sleeve. A split ring locking member is selectively operable in an unlocked state for permitting axial and rotational movement of said catheter relative to said sleeve and operable in a locked state for preventing such relative movement.

Abstract: An implantable device including a housing having a stud projecting percutaneously through an incision in the patient's skin. The stud defines a peripheral surface extending longitudinally inwardly from the stud outer end. The longitudinal peripheral surface is used as a substrate to carry a peripheral fibrous layer which extends longitudinally along the stud from its outer end adjacent to the skin incision to below the patient's epidermal and dermal skin layers for promoting laterally directed soft tissue ingrowth. The housing also defines a lateral shoulder surface oriented substantially perpendicular to the longitudinal peripheral surface. The shoulder surface also carries a porous layer conducive to promoting tissue ingrowth. The porous layers on the device allows tissue ingrowth into the interstices of both porous layers to form an enhanced infection resistant barrier while also providing improved device anchoring.
