A device for delivering a fluid to a patient, including an exit port, a dispenser for causing fluid from a reservoir to flow to the exit port, a local processor programmed to cause a flow of fluid to the exit port based on flow instructions from a separate, remote control device, and a wireless receiver connected to the local processor for receiving the flow instructions. The device also includes a housing free of user input components for providing flow instructions to the local processor, in order to reduce the complexity and costs of the device so that the device lends itself to being disposable in nature. A system and a kit are also described that include the fluid delivery device, a separate, remote control device, and accessories for transcutaneous delivery of fluid medications. Methods of utilizing the fluid delivery device to infuse fluid medications are additionally disclosed.

A system for performing minimally invasive cardiac procedures includes a pair of surgical instruments coupled to a pair of robotic arms with end effectors that can be manipulated to hold and suture tissue. The robotic arms are coupled to a pair of master handles by a controller to produce a corresponding movement of the end effectors. The movement of the handles is scaled such that the end effectors movement corresponds differently, typically smaller, than the movement performed by the hands of the surgeon. The input button allows the surgeon to adjust the position of the handles without moving the end effector, so that the handles can be moved to a more comfortable position. The system may include a robotically controlled endoscope allowing the surgeon to remotely view a surgical site. The surgeon may manipulate handles and move end effectors to perform a cardiac procedure.

An implantable intraocular physiological sensor (e.g., 2000) for measuring a physiological characteristic, such as intraocular pressure. The implantable intraocular physiological sensor may include a tubular main body (2102) configured to house one or more electrical components. The implantable intraocular physiological sensor may also include a sensor cap (2108) configured to he inserted into a first end of the tubular main body with a moisture barrier seal. The implantable intraocular physiological sensor may wirelessly transmit measurements to an external device.

A device (810) for delivering fluid to a person includes a reservoir (830) for containing a fluid to be delivered to the person; a fluid transport device (840) for dispensing fluid from the reservoir (830) to the person, the fluid transport device (840) including a proximal end in fluid communication with the reservoir (830) and a distal end having a penetrating member for piercing the skin of the person to facilitate the delivery of fluid to the person through the fluid transport device (840); a housing (820) containing the reservoir (830) and the fluid transport device (840), the housing (820) including an exit port (870) for receiving the distal end of the fluid transport device (840) upon injection of the distal end into the person and means for securing a first wall of the housing to the skin of the person; and an injection activation device including a driving mechanism contacting the fluid transport device (840) for driving the penetrating member from a first position within the housing, through the exit port to a second position external to the housing (820) and into the skin of the person.

Transcutaneous fluid delivery system

A dental laser assembly is disclosed for use in eradicating carious lesions in teeth, the treatment of sensitive teeth, as well as the removal of soft tissue, the incising of the frenum, opurculum, anesthesia of the tooth, etching enamel for restorations or orthodontic appliance fixation, the welding of fixed prosthesis, removal of bacterial flora periodontal pockets, removal and/or vaporization of healthy or necrotic pulp, the vertical and/or horizontal condensation of gutta percha or any other root canal sealant, the cauterization of blood vessels in the oral cavity, vaporizing bone tissue, removing tartar, apical fusion of foramina, enlarging and shaping root canal, removing carbon from surface of teeth, removal of enamel, bleaching teeth, etching dentin, separating orthodontic brackets, merging hydroxyapatite to bone and enamel, amalgam removal and undercutting of carious and/or healthy dentin and/or camentum. The laser assembly includes a housing having a cavity in which a pulsed laser is contained. The laser is excited so that the laser emits a laser beam along a predetermined axis that is in line with a fiber optic delivery system and at a pulse rate of one to 10,000 pulses per second and an average power variable from one tenth to 50 watts. A handpiece is dimensioned to be inserted into a human mouth while an optical fiber optically connects the laser output to the handpiece. The laser assembly also includes a continuous output aiming laser which, upon activation, provides a continuous laser aiming beam coaxial to the treatment beam. Both beams are then introduced into a fiber optic delivery system.

A noninvasive method is described for performing accurate and controlled reshaping of the anterior surface of the cornea in order to correct ocular refractive errors such as myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. The invention uses a light source emitting a wavelength or wavelengths with correct optical penetration depth(s) to induce changes in corneal stromal collagen without damaging the corneal endothelium, together with a light delivery and control means for producing the required irradiance, exposure time, and geometric pattern, in order to achieve the desired change in corneal shape. Corneal shape is monitored before, during, and after the procedure by a corneal topography system. Anterior corneal surface cooling by a transparent heat sink is used to prevent damage to the epithelium and to Bowman's layer.

A fiber optic probe and its use in performing a sclerostomy (forming a small hole in the sclera of an eye) as a treatment of glaucoma. The minimally dimensioned probe is designed to direct laser light out of its side and, as a result, allows a sclerostomy procedure to be performed with minimal trauma to the conjunctiva and other surrounding ocular tissues of the patient. A series of pulses of infrared laser radiation delivered through the side of the probe forms the hole in the sclera.

The tympanic membrane can be tightened by directing energy on spots of the tympanic membrane so as to heat up the collagen matrix layer and cause it to shrink Energy in the frequency range of 14 to 26 microns, which roughly corresponds to a collagen absorption range of from 10 to 150 cm-1, is used
