Abstract

The use of an implantable pump in the treatment of a condition characterised by inadequate fluid flow, in vivo, in or through a vessel, channel or conduit, is disclosed. This comprises inserting said implantable pump into said vessel, channel or conduit and causing it to operate when required. Control is preferably by telemetric means. Conditions susceptible to treatment in this way include urinary incontinence, pulmonary hypertension and inadequate pulmonary ventilation.

Description

Use of Implantable Pumps
This invention relates to the use of implantable pumps and to the treatment of medical conditions; and to apparatus for use therein. A variety of conditions are susceptible to treatment in accordance with this invention, as will be apparent from the examples given hereinafter. In these methods, implantable homeostatic pumps may be used.
According to one aspect of the present invention, there is provided the use of an implantable pump in the treatment of a condition characterised by inadequate fluid flow, in vivo , in or through a vessel, channel or conduit, which comprises inserting said implantable pump into said vessel, channel or conduit and causing it to operate when required.
Operation of the implantable pump is preferably controlled by telemetry. The pump may, in addition, be constructed and arranged to operate as a valve.
The vessel, channel or conduit may be the urethra of a patient; or a blood vessel, for example a pulmonary artery or a peripheral blood vessel. It may also be a tracheotomy tube inserted into the trachea of a patient.
According to a second aspect of the present invention, there is provided a method for the treatment of urinary incontinence, which method comprises:
(a) surgically inserting into the urethra of the patient a miniature pump, said pump comprising:
( 1 ) a motor having an impeller which is arranged so as, in use, to drive fluid in a direction away from the bladder;
( 2 ) means for supplying power to drive the impeller; and
(3) a sensor responsive to signals applied externally of the patient ' s body to activate the power supplying means and thus to drive the impeller, thereby permitting the controllable expulsion of urine from the patient;
and (b) supplying control signals from outside the body of the patient to actuate the pump.
Preferably, the means for supplying power to the motor is a device for generating electrical energy from electromagnetic waves which are directed through the patient ' s body towards the motor from an external source. The electromagnetic waves may be, for example, microwaves or radio waves . Such a power supply arrangement dispenses with the need for a replaceable power source such as a conventional battery.
The pump may, if desired, act as a valve - i.e. it may demonstrate three operative conditions, namely: (a) valve closed - no flow, no pumping action; (b) valve open - flow, but no pumping action; and (c) valve open, pumping activated - giving enhanced flow. In some patients, simple valve control will suffice to control their incontinence; in others, e.g. men with prostatic interference of the urethra, a positive pumping action may be required to expel urine.
Telemetric control of the pump is advantageous in that it allows the patient considerable freedom, thereby liberating him/her from many of the problems associated with urinary incontinence.
According to another aspect of the present invention, there is provided a method for the treatment of pulmonary hypertension, which method comprises:
(a) surgically inserting into a pulmonary artery of the patient a miniature pump, said pump comprising:
( 1 ) a motor having an impeller which is arranged so as, in use, to drive blood in a direction away from the heart towards the lungs;
(2) power supply means for supplying power to drive the impeller; and
( 3 ) a device for regenerating the power supply means in response to signals applied externally of the patient's body;
(b) operating said miniature pump to drive blood from the heart through said pulmonary artery to the lungs; and
(c) regularly supplying control signals from outside the body of the patient to regenerate said power supply means .
Preferably, the device for regenerating said power supply means comprises a device for generating electrical energy from electromagnetic waves which are directed through the patient ' s body towards the motor from an external source. The electromagnetic waves may be, for example, microwaves or radio waves. Such an arrangement dispenses with the need for a replaceable power source such as a conventional battery.
According to a third aspect of the present invention, there is provided a method of treating peripheral vascular ' disease, which comprises:
(a) surgically inserting into a peripheral blood vessel of the patient a miniature pump, said pump comprising:
( 1 ) a motor having an impeller which is arranged so as, in use, to assist blood circulation;
( 2 ) power supply means for supplying power to drive the impeller; and
( 3 ) a device for regenerating the power supply means in response to signals applied externally of the patient's body;
(b) operating said miniature pump to drive blood in the circulatory direction through the peripheral blood vessel; and
(c) regularly supplying control signals from outside the body of the patient to regenerate said power supply means .
According to a fourth aspect of the present invention, there is provided a method of pulmonary ventilation, which comprises:
(a) performing a tracheostomy and inserting a tracheotomy tube into the opening formed in the trachea to provide an artificial airway into the patient ' s lungs; (b) inserting into the tracheostomy tube a miniature pump, said pump comprising:
( 1 ) a motor having an impeller which is arranged so as, in use, to drive air into the lungs in one mode of action and to assist in expelling air from the lungs in a second mode of action;
( 2 ) means for supplying power to drive the impeller; and
( 3 ) a device for regenerating the power supply means in response to signals applied externally of the patient's body;
(b) operating said miniature pump cyclically to drive air into the lungs and to expel air from the lungs; and
(c) regularly supplying control signals from outside the body of the patient to regenerate said power supply means .
In this embodiment, the pump is preferably arranged to maintain a positive pressure of about 5cm Hg in order to prevent alveolar collapse.
If desired, the pump may be provided with a cooling system; this may, for example, be in the form of a water jacket surrounding that part of the tracheostomy tube within which the pump is located.
In all of the embodiments described above, the pump preferably comprises a hollow stator within which is mounted an impeller in the form of a shaft carrying at least one helical ridge or vane. It is also preferred, with each of the embodiments, to incorporate sensors, e.g. pressure sensors and flow sensors, at the two extremities of the pump ( input/output ends ) . These sensors are preferably arranged so that data they obtain can be transmitted externally of the patient by telemetric means.
