A safety IV catheter includes a unitary, resilient needle guard received in a catheter hub. The needle guard includes a proximal arm or wall that includes an opening through which a needle passes for axial movement. When the needle is retracted from the catheter, it releases the force that had previously prevented movement of the needle guard within the catheter hub. This in turn causes the needle guard to snap into a position in which it is clamped onto the needle shaft and in which its distal wall blocks access to the needle tip. In this condition, the spring needle guard and needle can be removed from the catheter hub. A slot or crimp may be formed in the needle shaft that engages with the needle guard after the protected needle and needle guard are removed from the catheter hub, thereby to prevent removal of the protected needle from the needle guard.

Systems for mitral valve repair are disclosed where one or more mitral valve interventional devices may be advanced intravascularly into the heart of a patient and deployed upon or along the mitral valve to stabilize the valve leaflets. The interventional device may also facilitate the placement or anchoring of a prosthetic mitral valve implant. The interventional device may generally comprise a distal set of arms pivotably and / or rotating coupled to a proximal set of arms which are also pivotably and / or rotating coupled. The distal set of arms may be advanced past the catheter opening to a subannular position (e.g., below the mitral valve) and reconfigured from a low-profile delivery configuration to a deployed securement configuration. The proximal arm members may then be deployed such that the distal and proximal arm members may grip the leaflets between the two sets of arms to stabilize the leaflets.

A cutting device includes an elongated shaft that extends between a proximal end and a distal end. A distal arm extends from the distal end of the elongated shaft. The distal arm includes an inner surface defining a cavity and an outer surface defining a blunt tip. At least one proximal arm extends from the distal end of the elongated shaft at a position proximal to the distal arm. The at least one proximal arm has an inner surface defining a cavity including a cutting portion configured to cut tissue.

A tarp deploying apparatus includes radial arm with a proximal arm and a distal arm. The distal arm is formed from a flexible material such as a double-walled hydraulic hose. The distal arm attaches to a tarp roller having a splined end. The distal arm is selectively removable from the distal arm to permit a hand crank with a female splined socket to be attached to the splined end of the tarp roller to permit hand operation of the tarp deploying system when the electric motor is not functional. A mounting bracket including two feet, a pair of legs and a support span allows easy mounting of the tarp deploying apparatus.

A jack and dolly assembly and system including a shaft defining a longitudinal axis extending along the shaft and an interior hollow; a reversible drive mechanism at least partially positioned in the interior hollow of the shaft; a proximal arm removably securable to the shaft and substantially perpendicular to the longitudinal axis; a distal arm removably securable to the drive mechanism, the distal arm being spaced from and substantially parallel to the proximal arm; wherein the reversible drive mechanism is operable to move the distal arm along the shaft.

A dressing aid is described. The dressing aid may include a main arm having a proximal end and a distal end, at least one (preferably at least two) proximal arm extending from the main arm proximal end, the proximal arm(s) having a distal end attached to the main arm proximal end and a proximal end attached to a proximal clip, and at least one (preferably at least two) distal arm extending from the main arm distal end, the distal arm(s) having a proximal end attached to the main arm distal end and a distal end attached to a distal clip. The proximal and distal arms may further comprise a hook. The proximal, distal and main arms are preferably formed of gooseneck tubing or another type of bendable but rigid tubular material.

A tarp deploying apparatus includes radial arm with a proximal arm and a distal arm. A flexible inelastic limit element is provided between the proximal and distal arms to prevent them from crossing over center to an angle that would cause the apparatus to bind.

Rain gutter and downspout cleaning tongs. The rain gutter cleaning tongs include a pair of arms, each having a distal portion and a proximal portion that are arranged at obtuse angles relative to each other. A gripping head is located at a distal end of the distal portion of each arm. The proximal arm portions are pivotally attached to each other and are spring loaded to bias their gripping surfaces away from each other. Optionally, a guide is attached to one of the arms for guiding the two arms relative to each other during operation.

A device and method for forming an anastomotic joint between two parts of a human or animal body having a hollow connector with at least two proximal arms biased towards an open position; and at least two distal arms biased towards an open position, wherein in use when pressure is applied to the proximal arms to overcome the bias into a position in which the proximal arms are closer to each other; similarly pressure is applied to the distal arms to overcome the bias into a position in which the distal arms are closer to each other; the distal end can be pushed into a passage in the first human or animal body part until the distal arms are located in the first lumen of the first body part and released allowing the distal arms to move to the biased position to urge against the first lumen of the first body part; and the proximal end can be pushed into a passage in the second human or animal body part until the proximal arms are located in the second lumen of the second body part and released allowing the proximal arms to move to the biased position to urge against the second lumen of the second body part.

A cutting device includes an elongated shaft that extends between a proximal end and a distal end. A distal arm extends from the distal end of the elongated shaft. The distal arm includes an inner surface defining a cavity and an outer surface defining a blunt tip. At least one proximal arm extends from the distal end of the elongated shaft at a position proximal to the distal arm. The at least one proximal arm having an inner surface defines a cavity including a cutting portion configured to cut tissue.

A securing device for preventing the splitting of a splittable sheath in the body of a treated subject, for facilitating the insertion of a splittable introducer and the splitting of said splittable sheath during removal of said introducer from the body of the subject, and optionally for interfacing said splittable introducer with other devices, comprising a “U”-like shaped portion having a distal arm and one or two proximal arms connected by a base, wherein said distal arm comprises an aperture accessible via a vertical slit passing from its upper side and terminating in said aperture, and wherein the gap defined between said distal arm and proximal arms is suitable for fitting a splittable introducer therebetween such that its splittable sheath is retained in the aperture provided in the distal arm.
