Abstract:
A seal-less, hand-held dispensing device for dispensing microliter quantities of a material at a site, where the device includes a support platform, first and second hollow members on the support platform, a compatibility sized plunger disposed in each hollow member, and an actuator having a thumb actuating surface thereon. The largest outside dimension of each compatibly sized plunger is in a range from about eighty percent (80%) to about ninety-five percent (95%) of the largest inside dimension (diameter) of a hollow member in which it is disposed. The actuator is operatively engagable with each plunger and movable with respect to the support platform through an actuating stroke defined between a fully extended position and a fully dosed position. Movement of the actuator through its actuating stroke displaces each compatibly sized plunger with respect to the hollow member in which it is disposed from a first, loaded, position to a second, dispensed, position.
Abstract:
A self-contained, hand-held spray dispensing device includes an internal source of pressurized fluid that exerts a motive force on a pair of liquid ejecting elements to cause each to eject a liquid into a discharge line. The liquids remain separated until each exits its discharge port. A pressurized fluid is directed over the outlet ends of the discharge line beginning before a flow interrupter in the discharge line is opened to permit flow therethrough and ceasing after liquid flow is terminated. The pressurized fluid flow over the outlet of the discharge line aerosolizes liquids emanating from the outlet ends. Each liquid ejecting element takes the form of a piston disposed within a cylinder. The pistons responds to pressurized fluid imposed directly thereon from the source to generate the motive force on the ejecting element.
Abstract:
Methods and apparatus for sealing a puncture or incision formed percutaneously in tissue separating two internal portions of the body of a living being with an anchor, a sealing plug and a filament connecting the anchor and sealing plug are disclosed. The methods and apparatus provide for automatic tamping of the sealing plug. In addition, torque required to tamp the sealing plug is automatically sensed and gear ratios of an automatic tamping device are automatically changed in response to sensed changes in torque. A planetary transmission may be used to automatically change gear ratios in response to the changes in torque.
Abstract:
Devices and methods are configured to allow transcervical or subclavian access via the common carotid artery to the native aortic valve, and implantation of a prosthetic aortic valve into the heart. The devices and methods also provide means for embolic protection during such an endovascular aortic valve implantation procedure.
Abstract:
Shape memory tissue engagement elements (15) are created using shape memory alloys or shape memory (SM) composite sheets (33, 36) with one or more SM material sheets (20, 32). Arrays of the tissue engagement elements may then be inserted or molded into flexible base materials forming pads for tissue engagement. In certain embodiments, the composite sheets incorporate two SM material layers (20, 32) having differing transition temperatures to allow activation of one layer for tissue engagement and activation of the second layer for tissue release. In exemplary embodiments, insertion of interconnected tissue engagement elements (46) into a base layer (19) with slots (48) provides a completed pad array. In alternative exemplary embodiments, vacuum forming of composite sheets (51) with cutting of corrugated sides (53) to form tissue engagement elements allow production of complete arrays of tissue engagement elements. Overmolding the arrays with a flexible base material (19) provides a completed pad.
Abstract:
A medical treatment device includes an elongate member having an internal volume, a proximal end, and a distal end, the internal volume extending from the proximal end to the distal end. The medical treatment device further includes a first coupler and a second coupler, the first coupler and the second coupler coupled to the internal volume of the elongate member; a first joining member and a second joining member, the first joining member coupled to the first coupler and the second joining member coupled to the second coupler. The first joining member is configured to attach to a first biological matter location, and the second joining member is configured to attach to a second biological matter location, the second location being distal to the first location. The second coupler is configured for manipulation to align relative the first coupler such that the second biological matter location relocates adjacent the first biological matter location. The first joining member and the second joining member are configured to join the first biological matter location to the second biological matter location.
Abstract:
The present invention discloses a minimally invasive multipoint fixation device adapted to laparoscopically locally reposition body tissues. The device comprises: a distal anchor, a proximal anchor and an elongated connecting element, adapted to interconnect between the distal anchor and the proximal anchor. The distal and the proximal anchors are characterized by two configurations: (i) a FOLDED CONFIGURATION; and, (ii) a DEPLOYED CONFIGURATION. The fixation device further comprises deployment means adapted to deploy the distal and the proximal anchors by reconfiguring the same from the FOLDED CONFIGURATION to the DEPLOYED CONFIGURATION.
Abstract:
The present invention relates to wound closure devices, devices and systems for delivery, kits and methods therefor. The wound closure devices can achieve wound closure in lieu of compression and can be configured to be quickly deployable by an introducer or from outside the body.

Abstract:
A system for bonding living tissue including first tissue displacer functionality operative initially to cause displacement of edges of tissue into a mutual touching relationship along a seam prior to bonding thereof and second tissue displacer functionality operative following operation of the first tissue displacer functionality to cause displacement of the edges into a mutual non-touching relationship wherein the edges are in mutual propinquity.
