A low profile stepped delivery system for retracting trigger wires from a prosthesis to release the prosthesis from a delivery device. A rod is disposed within an axial bore of a handle. The rod has a first longitudinal surface and a second longitudinal surface. A first engagement mechanism is disposed on the first longitudinal surface and a second engagement mechanism disposed on the second longitudinal surface. A wire coiling assembly is disposed at an end of the of the handle and comprises a first rotary gear that is adapted to be rotated by the first engagement mechanism, a second rotary gear that is adapted to be rotated by the second engagement mechanism, a first wire spool that is coupled to a rotation of the first rotary gear, and a second wire spool that is coupled to the rotation of second rotary gear. The first wire spool is configured to secure a first trigger wire and the second wire spool is configured to secure a second trigger wire.

Low profile stepped delivery system

A device for obtaining selective rigidity with respect to a patient is provided. The device includes a scaffold that is arranged to be flexible when in a first relaxed configuration, wherein the scaffold is configured to become substantially more rigid when a suction force is applied thereto. The scaffold comprises first and second opposing outer flexible layers that are sealed together to form a plurality of elongate pockets therein, and an expanded structure disposed within the plurality of elongate pockets and in communication with a vacuum port that receives the suction force.

Medical device with selective rigidity

An elongate access sheath comprises a proximal portion and a lumen. The proximal portion supports a control handle, a brake pad, a tension gear, and a locking trigger. A deflector filament extends through the lumen and is coupled to the tension gear. The tension gear includes an outside and an inner engagement portion. The brake pad comprises a slot and an outside engagement portion. The locking trigger includes a pin disposed within the brake pad slot. The control handle includes a lever and an engagement portion. Upward movement of the lever engages the engagement portion with the outside engagement portion of the tension gear to rotate the tension gear in a first direction and slides the deflector filament to bend the lumen distal portion. Translation of the locking trigger engages the brake pad and the tension gear to prevent rotation of the tension gear in an opposite second direction.

A valve assembly for controlling fluid communication between fluid chambers in a device such as an inflatable device includes a valve body having first and second ports for fluidly connecting to first and second fluid chambers, and defining a plurality of primary valve seats in series between the ports. A plurality of compound valves are within the valve body and each includes a primary valve member movable to close or open one of the primary valve seats, and a secondary valve member movable to close or open a secondary valve seat in the primary valve member.

An injection device for injecting a medicant into a plurality of tissue sites in a patient for a selected treatment is constructed and arranged such that the number of tissue sites is the total number for the selected treatment thereby requiring a single positioning step. The injection device includes a body having a syringe and a control linkage, the syringe including a plurality of barrels, and a cooperating plunger array including a plurality of plungers. Each barrel receives a corresponding plunger. The injection device further includes a plurality of injection needles connected to the syringe wherein one injection needle is connected to each barrel, a multi-lumen tip, a shaft connected to the multi-lumen tip and extending between said multi-lumen tip and said body. The control linkage is connected to each needle so as to move each needle between a deployed injection position and a retracted position.

Multi-barrel syringe injection system

A deployment device for repair of a transected body vessel is described herein. Device can have a handle and one or more shafts coupled thereto. A prosthesis being retained by a sheath can be coupled to the delivery device. The sheath can have end portions coupled to one or more shafts. Rotation of a shaft can retract a sheath portion away from either end of the prosthesis for expansion thereof prior to the middle of the prosthesis. Continued rotation of a shaft can completely remove the sheath from the prosthesis, so that the prosthesis is fully expanded and couples the first and second vessel portions of the transected vessel together. Prosthesis may be retained by overlapping a tubular sheath and lacing a threading member therethrough. Prosthesis may be retained by a splittable sheath.

Emergency vascular repair prosthesis deployment system

A device for inferior retrieval of a vena cava filter includes an outer sheath with a first radial window closer to the distal end than the proximal end of the outer catheter; an inner sheath generally extending movably inside the lumen of the outer sheath and having a second radial window; and a snare tool having an elongated guide element extending through the inner sheath and a snare loop distally attached to the guide element. The snare loop is extendable outward through the two radial windows.

Filter retrieval device

Among other things, there are disclosed embodiments of a biopsy device using relative rotational motion to obtain a full-core biopsy sample. Inner and outer tubular members are provided connected to a handle. Each member includes a slit, and the members are rotatable with respect to each other. The device is inserted into a patient to a sampling site, and with the slits co-oriented, is extended into the sampling site. Tissue enters the tubular members through the slits, and one or both members are rotated to cut off and enclose tissue within the inner tubular member.

Closed side-sampling biopsy device

Drainage catheters for use in a variety of medical procedures are presented herein. The drainage catheter features an improved tension member locking mechanism. In use, once the drainage catheter is placed as desired, a second connector piece is rotated relative to a first connector piece to wind the tension member around a spooling region and pull the distal end of the catheter tube into a locked configuration. Once the tension member is tensioned, the first and second connector pieces are pulled into a locking engagement thereby securing the catheter tube in the locked configuration.
