The present invention provides a branching endoluminal prosthesis for use in branching body lumen systems which includes a trunk lumen and first and second branch lumens. The prostheses comprises a radially expandable tubular trunk portion having a prosthetic trunk lumen, and radially expandable tubular first and second branch portions with first and second prosthetic branch lumens, respectively. A radially expandable tubular Y-connector portion provides fluid communication between the prosthetic trunk lumen and the first and second prosthetic branch lumens. Although it is often considered desirable to maximize the column strength of endoluminal prostheses, and although the trunk portion will generally have a larger cross-section than much of the remainder of a branching endoluminal prostheses, the expanded trunk portion is more axially flexible than the expanded Y-connector portion, as insufficient flexibility along the trunk portion may result in leakage between the prosthesis and the trunk lumen of the body lumen system. In contrast, the Y-connector portion benefits form a less axially flexible structure to avoid distortion of the flow balance between the luminal branches.

A miniaturized obstruction treatment device, e.g., a resilient brush, particularly adapted for medical use formed at the distal end of an elongated brush drive shaft having a hollow lumen formed therein for introduction over a guidewire. The brush drive shaft is enclosed in the lumen of a brush delivery catheter, and the brush is adapted to be garaged in a distal end section of the brush delivery catheter lumen. A Y-connector and a brush sub-assembly connector are attached to the proximal end of the brush delivery catheter and form a brush sub-assembly with the brush drive shaft and brush. The Y-connector allows infusion of thrombolytic agents into the brush delivery catheter lumen for emission at the distal end opening thereof adjacent the brush. In use, the brush sub-assembly connector connects the brush sub-assembly with a drive motor unit connector of a drive motor unit. The drive motor unit receives the proximal end of the drive shaft and rotates it to rotate the brush bristles. The brush and brush drive shaft distal section are automatically extended out of the catheter lumen distal end opening when the sub-assembly connector and the drive motor unit connector positively lock together. Simultaneously, a drive hub of the brush drive shaft locks into a drive chuck of a drive motor unit to enable rotation of the drive shaft, and the drive shaft proximal end is seated in a dynamic seal that inhibits infiltration of blood and thrombolytic agent into the drive motor housing.

A releasable medical device connector comprises a connector fitting with a spin nut which connects to an adaptor. The connector fitting has at least one radially extending member with a variable radius cross section. The spin nut is disposed upon the connector fitting proximal of the radially extending member and is both axially slidable and rotatable upon the elongated body of the connector fitting. A screw thread within a proximal portion of the spin nut is used to secure the tapering portion of the connector fitting to an external thread disposed upon the adaptor. To release the connector, the spin nut is unscrewed from the adaptor and slid so that a distal receptacle of the spin nut engages the radially extending member of the connector fitting. With the spin nut and connector fitting engaged, the medical line can be released from the adaptor by twisting and pulling upon the spin nut. The radially extending member of the connector fitting may also be used to secure the medical line to a retainer comprising one or more slots.

A dual syringe assembly that allows for two liquids to be sequentially injected through the same needle. By way of example, one syringe may contain a steroid and the other syringe may hold an anesthetic. The syringes are coupled to a needle by a connector. The needle can be inserted into a hand by medical personnel and manipulated until placed in contact with a tendon sheath. The steroid can be administered by depressing a plunger of the syringe that contains the steroid. The anesthetic can then be injected into the hand by depressing the plunger of the other syringe. The needle is then pulled out of the hand. The injection of the anesthetic flushes steroid from the needle and the Y-connector so that steroid is not ejected onto surrounding tissue when the needle is removed from the hand.
